The widespread use of mobile internet and smart applications has led to an explosive growth in mobile data traffic, which will continue due to the emerging need of connecting people, machines, and applications in an ubiquitous manner through the mobile infrastructure. The efficient and satisfactory operation of all these densely deployed networks hinges on a suitable backhaul and fronthaul provisioning. The research community is working to provide innovative technologies with extensive performance evaluation metrics along with the required standardisation milestones, hardware and components for a fully deployed network by 2020 and beyond.
Access, Fronthaul and Backhaul Networks for 5G & Beyond provides an overview from both academic and industrial stakeholders of innovative backhaul/fronthaul solutions. Covering a wide spectrum of underlying themes ranging from the recent thrust in edge caching for backhaul relaxation to mmWave-based fronthauling for radio access networks, this book is essential reading for engineers, researchers, designers, architects, technicians, students and service providers in the field of networking, mobile and wireless and computing technologies working towards the deployment of 5G networks.
The Criminal Justice Technology Forecasting Group (CJTFG) deliberated on the effects that major technology and social trends could have on criminal justice in the next two to five years and identified potential responses. This report captures the results of the group’s meetings and initiatives, presents the emerging trends and highlights of the group’s discussion, and presents the results of analyses to assess connections between the trends.

Advanced Signal Processing
D.J. Creasey The Institution of Engineering and Technology, 1985 Library of Congress TK5102.5.A33 1985 | Dewey Decimal 621.38043
The IEE in association with the IEEE and IERE organised an international specialist seminar on Advanced Signal Processing in Radar, Sonar and Communications, in September 1984. The Seminar was held at the University of Warwick and this book contains a collection of the papers presented. Some of the material is of a tutorial nature while some of it represents the latest state-of-the-art. Inevitably, because signal processing is limited by the components available, the subject matter ranges from the individual components and their impact on signal processing, through to the design and assessment of complete systems. The individual contributions come from industry, educational establishments and government research laboratories in the UK and the USA. The order of presentation in the book mainly follows the order in which the papers were presented at the seminar.
Body centric wireless networking and communications is an emerging 4G technology for short (1-5 m) and very short (below 1 m) range communications systems, used to connect devices worn on (or in) the body, or between two people in close proximity. It has great potential for applications in healthcare delivery, entertainment, surveillance, and emergency services. This book brings together contributions from a multidisciplinary team of researchers in the field of wireless and mobile communications, signal processing and medical measurements to present the underlying theory, implementation challenges and applications of this exciting new technology.
Topics covered include: diversity and cooperative communications in body area networks; ultra wideband radio channel characterisation for body-centric wireless communication; sparse characterisation of body-centric radio channels; antenna / human body interactions in the 60 GHz band; antennas for ingestible capsule telemetry; in vivo wireless channel modelling; diversity and MIMO for efficient front-end design of body-centric wireless communications devices; on-body antennas and radio channels for GPS applications; textile substrate integrated waveguide technology for the next-generation wearable microwave systems; ultra wideband body-centric networks for localisation and motion capture application; down scaling to the nano-scale in body-centric nano-networks; and the road ahead for body-centric wireless communication and networks.
The International Communications Satellite Systems Conference (ICSSC) is one of the most influential technical conferences in the field. The 36th edition was held in October 2018 in Niagara Falls, Canada. These proceedings present a broad spectrum of space communications topics from the conference, from the evolution of GEO from traditional area coverage to Ultra High Throughput Satellites (UHTS), the growing number of mega constellations expected to enter service in the next decade, navigation applications such as vehicle autonomy, wideband data backhaul from scientific and remote sensing payloads in LEO, and the extension of the 5G network to near earth, lunar and deep space environments in support of human exploration.
As biometrics-based identification and identity authentication become increasingly widespread in their deployment, it becomes correspondingly important to consider more carefully issues relating to reliability, usability and inclusion. One factor which is particularly important in this context is that of the relationship between the nature of the measurements extracted from a particular biometric modality and the age of the sample donor, and the effect which age has on physiological and behavioural characteristics invoked in a biometric transaction.
In Age Factors in Biometric Processing an international panel of experts explore the implications of ageing on biometric technologies, and how such factors can be managed in practical situations. Topics include understanding the impact of ageing on biometric measurements; age factors as barriers/opportunities in relation to performance; modality-related approaches to management of age factors; implications for practical application; and future trends and research challenges.
Age Factors in Biometric Processing provides an outstanding overview of this topic for the rapidly expanding community of stakeholders in biometrics based identification solutions in academia, industry and government.
One of the many problems facing designers of fibre systems is the basic question of how best to transmit analogue-sourced signals; either on dedicated point-to-point links or as part of mixed-mode traffic on a predominantly digital fibre service network. This book discusses the fundamental principles involved and describes a variety of techniques and applications. The chapters have been contributed by invited researchers with expertise in a range of areas and outline the latest methods and analytical approaches, components and systems.
The general topics covered include subcarrier multiplexing (SCM) and coherent techniques, transmissions of TV signals, soliton and pulse time modulation methods and performance assessment of subcarrier multiplexed optical systems. Specific technological and system component issues addressed include generation and delivery of millimetre-waves over fibre systems for mobile communications, tuned optical receivers for fibre SCM systems and optical fibre amplifiers, and wavelength division multiplexing (WDM).
Written by leading authorities in their fields, this graduate level text should be of interest to all scientists and engineers concerned with transmission of analogue-sourced information over fibre systems.
Since ATM was identified by the CCITT in 1988 as the target transfer mode for broadband communications, there has been considerable research activity on the topic world-wide. Within Europe, the RACE programme of the European Community has brought together experts from a wide variety of organisations to work on several projects. This book results from the work of one of those projects.
Aimed at those interested in ATM generally, or those needing to understand the issues in designing or implementing broadband networks, the book draws on the results of the research project to present a description of ATM from a network point of view. Starting with the principles of ATM, it goes on to cover topics such as network performance, network structure, evolution and interworking. It also discusses more general issues including numbering, charging and the need for intelligence in the network. It concludes by explaining the current position on traffic engineering for broadband ATM networks.
Cable television is arguably the dominant mass media technology in the U.S. today. Blue Skies traces its history in detail, depicting the important events and people that shaped its development, from the precursors of cable TV in the 1920s and '30s to the first community antenna systems in the 1950s, and from the creation of the national satellite-distributed cable networks in the 1970s to the current incarnation of "info-structure" that dominates our lives. Author Patrick Parsons also considers the ways that economics, public perception, public policy, entrepreneurial personalities, the social construction of the possibilities of cable, and simple chance all influenced the development of cable TV.
Since the 1960s, one of the pervasive visions of "cable" has been of a ubiquitous, flexible, interactive communications system capable of providing news, information, entertainment, diverse local programming, and even social services. That set of utopian hopes became known as the "Blue Sky" vision of cable television, from which the book takes its title.
Thoroughly documented and carefully researched, yet lively, occasionally humorous, and consistently insightful, Blue Skies is the genealogy of our media society.
This book explores some of the technological challenges in the application of digital communications technology in the home, including provision of fast, 'always on' internet connections. It looks at the ways consumers will use broadband access and what the key applications will be for provider and consumer. More broadly it aims to describe how communication to and within the home is evolving, and how people's lives are changing as they take advantage of the new technology and its applications.
The expert contributors consider delivery mechanisms for broadband, connecting the home to external networks as well as connecting devices and applications within the home. They discuss how people use and relate to the technology, and how it should be developed to meet their evolving needs. Current applications are described and how new applications are being developed to take advantage of new digital technology. Finally two visionaries give their insights into aspects of the future for the home environment and how much it will be a digital home.
This fascinating book provides balanced coverage of the issues surrounding this next phase of the development of communications and the Internet, which may transform our homes and the way we live. It will be of major interest to engineers and other professionals working in communications, IT, new technology and entertainment, as well as those active in research within a number of fields of technology.
This book provides the engineer and manager with a very good understanding of the processes needed to effectively perform the system design for broadband communication systems and home networking approaches. It is ideal for all engineers that design and analyze wireless, spread spectrum and basic broadband communication systems and are involved with the design of basic networking systems. It provides a good intuitive approach starting from basic telephony to satellite communications.
Communications networks are now dominated by Internet protocol (IP) technologies. Every aspect of networking, from access to the core network to the surrounding operational support systems, has been radically affected by the rapid development of IP technologies. This book comprehensively reviews the design, provision and operations of carrier-scale Internet networks. A good balance between leading edge technology and many of the practical issues surrounding carrier-scale IP networks is presented, including: the challenges in building and scaling a carrier-scale IP network, how to physically build and maintain Points of Presence (PoP) around the world, core transmission networks for the new millenium, delivery of IP over broadband access technologies and wireless access, dial access platform, an overview of satellite access networks, operations for the IP environment, operational support systems for carrier-scale IP networks, IP address management, traffic engineering, and IP virtual private networks. This makes for essential reading for telecommunications engineers and managers, researchers and postgraduate students in this rapidly changing area of communications technology.
A cognitive radio is a transceiver which is aware of its environment, its own technical capabilities and limitations, and those of the radios with which it may communicate; is capable of acting on that awareness and past experience to configure itself in a way that optimizes its performance; and is capable of learning from experience. In a real sense, a cognitive radio is an intelligent communications system that designs and redesigns itself in real time.
Cognitive Radio Engineering is both a text and a reference book about cognitive radio architecture and implementation, intended for readers who want to design and build working cognitive radios. It takes the reader from conceptual block diagrams through the design and evaluation of illustrative prototypes. An important goal is to bridge the divide between radio engineers, who often have little experience with the computational resource and timing issues inherent in cognitive radios, and computer engineers who often are unaware of RF issues like dynamic range, intermodulation products, and acquisition time.
Following a brief overview of cognitive radio history and a high-level look at cognitive radio operation, the book presents a detailed study of cognitive engine design and analysis. After treating RF subsystems the book considers computational platforms and computation issues in cognitive radios, followed by system integration, evaluation methods for cognitive radio, and cognitive radio design for networking. The book concludes with coverage of cognitive radio applications in communications.

Signalling is the life-blood of telecommunications and common-channel signalling is the key to providing flexible and cost-effective services to customers. This book commences with the basics of signalling and then unveils the complexities of common-channel signalling systems. The book is written to appeal to a wide range of readership. The novice can build up a comprehensive understanding of signalling by systematically making progress through the book. Experts in telecommunications who wish to understand the specialist subject can select appropriate text, guided by the chapter summaries. Experts in signalling will find the book useful in extending their knowledge of a very broad subject. The glossary cuts through the maze of jargon.
The book describes basic principles, channel-associated signalling systems and the CCITT Signalling System No. 6. However, the focus of the book is upon common-channel signalling and CCITT Signalling System No. 7 and the Digital Subscriber Signalling System No. 1 are described in detail. The latest techniques are explained including, for example, the form of signalling required for gaining access to remote databases. The interworking of common-channel signalling systems is also described.
“Alaska is now open to civilization.” With those six words in 1900, the northernmost territory finally had a connection with the rest of the country. The telegraph system put in place by the US Army Signal Corps heralded the start of Alaska’s communication network. Yet, as hopeful as that message was, Alaska faced decades of infrastructure challenges as remote locations, extreme weather, and massive distances all contributed to less-than-ideal conditions for establishing reliable telecommunications.
Connecting Alaskans tells the unique history of providing radio, television, phone, and Internet services to more than six hundred thousand square miles. It is a history of a place where military needs often trumped civilian ones, where ham radios offered better connections than telephone lines, and where television shows aired an entire day later than in the rest of the country.
Heather E. Hudson covers more than a century of successes while clearly explaining the connection problems still faced by remote communities today. Her comprehensive history is perfect for anyone interested in telecommunications technology and history, and she provides an important template for policy makers, rural communities, and developing countries struggling to develop their own twenty-first-century infrastructure.
This book describes how smart cities can be designed with data at their heart, moving from a broad vision to a consistent city-wide collaborative configuration of activities. The authors present a comprehensive framework of techniques to help decision makers in cities analyse their business strategies, design data infrastructures to support these activities, understand stakeholders' expectations, and translate this analysis into a competitive strategy for creating a smart city data infrastructure. Readers can take advantage of unprecedented insights into how cities and infrastructures function and be ready to overcome complex challenges. The framework presented in this book has guided the design of several urban platforms in the European Union and the design of the City Data Strategy of the Mayor of London, UK.
There has been unprecedented development in data communications and services since the first edition of this book was published in 1986. In less than a decade the technology has advanced beyond all recognition and the first edition is now really no more than an interesting historical record. The second edition, published in 1989, reflected some of these developments and introduced the then emerging proposals for an integrated services digital network (ISDN). Since that date ISDN has become a fact and has already begun to be superseded by proposals and standards for a broadband ISDN (B-ISDN), offering greatly enhanced and flexible data rates over a public network based mainly on optical fibre transmission. Optical fibre technology is also being used in wide-area private digital networks and for high-capacity internetworking operations.
This third edition has new chapters on broadband ISDN, wide-area internetworking and second generation (broadband) LANs and MANs. The chapters from the second edition on data services over cellular and broadcast radio have been retained and updated. The chapter on standards and interfaces has needed to be completely revised.
The final chapter gives a network user's view of the likely scenario for the development of image networks in the foreseeable future. On the back cover of the second edition I commented that what four years ago appeared as simply speculation was now a reality. The same is true for this third edition. If there should be a fourth edition in another four years time, we should not be surprised to find that duplex visual image communication, as opposed to broadcast TV, has become an accepted part of our way of life.
A worldwide digital and wireless communication revolution has taken place in the last 20 years which has created a high demand in industry for graduates with in-depth expertise in digital transmission techniques and a sound and complete understanding of their core principles. Digital communications: Principles and systems recognises that although digital communications is developing at a fast pace, the core principles remain the same. It therefore concentrates on giving the reader a thorough understanding of core principles and extensive coaching in the solution of practical problems drawn from various application areas. The intention is that after studying the material presented, the student will have a solid foundation free of knowledge gaps, and will be fully equipped to undertake digital communication systems analysis, design and computer simulations, and to deal with specialised applications and follow advances in the technology. Topics covered include:
overview of digital communication
linear and nonlinear channels and systems
sampling of baseband and bandpass signals
quantisation and PCM
source coding and lossless data compression
line codes and modulation
transmission through bandlimited AWGN channels
transmitted digital signals
error control coding
link analysis and design.
Many works on emerging digital transmission techniques are largely confined to academic research papers. This book will give postgraduate students and practicing engineers a sound mastery of the subject.
The processing and analysis of signals and data is today a fast-growing and crucial activity in a diverse range of fields, not only in communications and image technology itself but in almost every other research area in science. The purpose of this book is to explain some of the theoretical concepts that underly the methods now in common use. The author starts from the assumption that some knowledge of the basic principles should be in the toolkit of every engineer or scientist working with signals or data.
Thus the book introduces the basic theory of discrete-time systems, processes and signals including discrete transforms. It explains classical digital filtering, and averaging methods to improve the signal-to-noise ratio or repetitive signals. Correlation and spectral analysis approaches to analysing signals are covered as well as methods to estimate and define unknown signals. Non-linear processing is introduced including the use of neural networks. The final chapter extends what the reader has learnt into the arena of multidimensional signals and data.
The aim of the book is not to be deeply rigorous mathematically but rather to provide full and practical explanation of the theories and concepts behind these processing techniques which are largely available today as software programs and packages.
In this smart and incisive work, Karen J. Head describes her experience teaching a Massive Open Online Course (MOOC) and the attendant pressure on professors, especially those in the humanities, to embrace new technologies in the STEM era. And yet, as she argues, MOOCs are just the latest example of the near-religious faith that some universities have in the promise of technological advances. As a teacher of rhetoric, Head is well versed at sniffing out the sophistry embedded in the tech jargon increasingly rife in the academy. Disrupt This! is a broader-based critique of the promises of technological “disruption” and the impact of Silicon Valley thinking on an unsuspecting, ill-prepared, and often gullible university community grasping for relevance, while remaining in thrall to the technologists.
The Internet of Things (IoT) - the emerging global interconnection of billions of 'smart' devices - will be collecting increasing amounts of private and sensitive data about our lives, and will require increasing degrees of reliability and trustworthiness in terms of the levels of assurance provided with respect to confidentiality, integrity and availability. This book examines these important security considerations for the IoT.
Topics covered include a security survey of middleware for the IoT; privacy in the IoT; privacy and consumer IoT - a sensemaking perspective; a secure platform for smart cities and IoT; model - based security engineering for the IoT; federated identity and access management in IoT systems; the security of the MQTT protocol; securing communications among severely constrained, wireless embedded devices; lightweight cryptographic identity solutions for the IoT; and a reputation model for the IoT.
Restrictions on foreign investment in U.S. telecommunications firms have harmed the interests of American consumers and investors, argues J. Gregory Sidak in this convincing study. Sidak shows why these restrictions, originally intended to protect America from the perils of wireless telegraphy by foreign agents, should be repealed.
Basing his analysis on legislative history, statutory and constitutional interpretation, and finance and trade theory, Sidak shows that these restrictions no longer serve their national security purpose (if they ever did). Instead they deny American consumers lower prices and more robust innovation, hamper access of American investors to foreign telecommunications markets, and unconstitutionally impinge on freedom of speech. Sidak's study encompasses the Telecommunications Act of 1996, recent global mergers such as British Telecom-MCI, and the 1997 World Trade Organization agreement to liberalize trade in telecommunications services.
Digital media histories are part of a global network, and South Asia is a key nexus in shaping the trajectory of digital media in the twenty-first century. Digital platforms like Facebook, WhatsApp, and others are deeply embedded in the daily lives of millions of people around the world, shaping how people engage with others as kin, as citizens, and as consumers. Moving away from Anglo-American and strictly national frameworks, the essays in this book explore the intersections of local, national, regional, and global forces that shape contemporary digital culture(s) in regions like South Asia: the rise of digital and mobile media technologies, the ongoing transformation of established media industries, and emergent forms of digital media practice and use that are reconfiguring sociocultural, political, and economic terrains across the Indian subcontinent. From massive state-driven digital identity projects and YouTube censorship to Tinder and dating culture, from Twitter and primetime television to Facebook and political rumors, Global Digital Cultures focuses on enduring concerns of representation, identity, and power while grappling with algorithmic curation and data-driven processes of production, circulation, and consumption.
Hand-based biometrics identifies users by unique features in their hands, such as fingerprints, palmprints, hand geometry, and finger and palm vein patterns. This book explores the range of technologies and methods under development and in use for hand-based biometrics, with evaluations of the advantages and performance of each. The inclusion of significant material on the relevant aspects of the physiology of the hand is a particularly useful and innovative feature.
Topics covered in this book include inner and outer hand physiology and diseases; nail structure and common disorders; fingerprint recognition; synthetic fingerprints; finger vein recognition; palm vein biometrics; hand shape recognition and palm print recognition; 3D hand shape recognition; and spoofing and anti-spoofing methods.
With contributions from an international panel of experts in this field, Hand-Based Biometrics is essential reading for researchers, students and engineers working in biometrics and security.
The Hello Girls
Elizabeth Cobbs Harvard University Press, 2017 Library of Congress D639.T4C63 2017 | Dewey Decimal 940.4173082
In 1918 the U.S. Army Signal Corps sent 223 women to France to help win World War I. Elizabeth Cobbs reveals the challenges these patriotic young women faced in a war zone where male soldiers resented, wooed, mocked, saluted, and ultimately celebrated them. Back on the home front, they fought the army for veterans’ benefits and medals, and won.
An innovative approach to the relationship between filmmaking and society during Hollywood's golden age.
The 1910s and 1920s witnessed the inception of a particular brand of negotiation between filmdom and its public in the United States. Hollywood, its proponents, and its critics sought to establish new connections between audience and industry, suggesting means by which Hollywood outsiders could become insiders. Hollywood Outsiders looks at how four disparate entities--the Palmer Photoplay correspondence school of screenwriting, juvenile series fiction about youngsters involved in the film industry, film appreciation and character education programs for high school students, and Catholic and Protestant efforts to use and influence filmmaking--conceived of these connections, and thus of the relationship of Hollywood to the individual and society. Anne Morey's exploration of the diverse discourses generated by these different conjunctions leads to a fresh and compelling interpretation of Hollywood's place in American cultural history.
In its analysis of how four distinct groups, each addressing constituencies of various ages and degrees of social authority, defined their interest in the film industry, Hollywood Outsiders combines concrete discussions of cultural politics with a broader argument about how outsiders viewed the film industry as a vehicle of self-validation and of democratic ideals.
Anne Morey is assistant professor of English and performance studies at Texas A&M University.
This book describes the stage-by-stage creation and development, from the mid-nineteenth century to the present day, of the remarkable global communications technologies that have profoundly transformed the way that people live and work.
Written in a highly readable style, this book provides a fascinating account of the key innovators from Faraday, Maxwell and Hertz to the inventors of the transistor, microchip, optical fibre systems and the World Wide Web. The book explores the background and motivation of these pioneers and the social and economic environment in which they worked. The significance of each innovative step is shown in terms of the impact - in scale and relevance - on today's communications world. John Bray also looks to the future for innovations yet to come.
This book will be interest to all those interested in the human thread running through the history of technological advances in telecommunications and broadcasting.
This book explains how intelligence can be introduced into digital telephone networks. Beginning by outlining the basic principles of Intelligent Networks (IN), it tracks the application of the IN principle of separation of the service logic for advanced telephony services from the underlying call control infrastructures. The book explains how large public networks are updated to incorporate IN principles for advanced telephony services. This is illustrated using many practical examples which are set against a background of following the ETSI standards within the overall ITU-T framework of recommendations. This book is targeted at postgraduate telecommunications students, or engineers requiring a concise and practical introduction to IN.
This report examines the portfolio of tools funded by the State Department’s Bureau of Democracy, Human Rights, and Labor that help support Internet freedom and assesses the impact of these tools in promoting U.S. interests (such as freedom of expression, freedom of the press, and the free flow of information) without enabling criminal activity.
Broadband networks, such as asynchronous transfer mode (ATM), frame relay, and leased lines, allow us to easily access multimedia services (data, voice, and video) in one package. Exploring why broadband networks are important in modern-day telecommunications, Introduction to Broadband Communication Systems covers the concepts and components of both standard and emerging broadband communication network systems.
After introducing the fundamental concepts of broadband communication systems, the book discusses Internet-based networks, such as intranets and extranets. It then addresses the networking technologies of X.25 and frame relay, fiber channels, a synchronous optical network (SONET), a virtual private network (VPN), an integrated service digital network (ISDN), broadband ISDN (B-ISDN), and ATM. The authors also cover access networks, including digital subscriber lines (DSL), cable modems, and passive optical networks, as well as explore wireless networks, such as wireless data services, personal communications services (PCS), and satellite communications. The book concludes with chapters on network management, network security, and network testing, fault tolerance, and analysis.
With up-to-date, detailed information on the state-of-the-art technology in broadband communication systems, this resource illustrates how some networks have the potential of eventually replacing traditional dial-up Internet. Requiring only a general knowledge of communication systems theory, the text is suitable for a one- or two-semester course for advanced undergraduate and beginning graduate students in engineering, as well as for short seminars on broadband communication systems.
The aim of this book is to give a clear and concise exposition of the principles and practice of satellite communications by describing the development of communications-satellite services. It will be useful both to engineers who have worked in other fields of telecommunication and to students.
The book describes the development of communications satellite services and explains how satellites and earth stations have evolved to meet changing requirements. It deals in a simple but practical way with the physics and geometry of the geostationary orbit, and the construction and operation of satellites and launch vehicles. It gives a thorough analysis of the essential factors governing the quality of speech, data and television signals received via satellite. Particular attention is paid to growth areas in satellite communications, including analogue television transmission, digital methods of transmission of speech and data, the use of satellites for maritime, aeronautical and land-mobile communications and VSATs (very-small aperture terminals).
Iris recognition technologies for identity management are already deployed globally in several large-scale nationwide biometric projects and are currently entering the mobile market. More recently, periocular recognition has been employed to augment the biometric performance of the iris in unconstrained environments where only the ocular region is present in the image.
Iris and Periocular Biometric Recognition provides an overview of scientific fundamentals and principles of iris and periocular biometric recognition over six broad areas: an introduction to iris and periocular recognition; a selective overview of issues and challenges; soft biometric classification; security aspects; privacy protection and forensics; and future trends. With contributions from experts in industry and academia, this book is essential reading for researchers, graduate students and practitioners in biometrics and related fields.
ISDN presents a new challenge for educators and trainers. This book provides an introduction to the technology for educators interested firstly in whether to use it and secondly in how to use it. The first three chapters discuss practical, educational and strategic issues related to these two questions. The following ten chapters provide case studies of education and training uses of ISDN technologies in Europe, the US and Australia. These involve videoconferencing, audiographics, desktop conferencing and image banks. The book concludes with a large glossary of explanatory material.
Telecommunication and internet services are constantly subject to change, seeking the customer's full satisfaction. Enriching these services with innovative approaches such as contextaware, social, mobile, adaptable and interactive mechanisms, enables users to experience a variety of personalized services seamlessly across different platforms and technologies. In this sense, advertising is no exception, especially if we consider that it will become the business enabler for next generation services. Nevertheless, currently there is no cross-domain solution capable of delivering real-time advertising across heterogeneous environments or domains, and at the same time, address user needs, desires and intentions. This is because most of the products available today are only used within isolated environments / silos. Therefore, managing advertising campaigns across different verticals is still very complex. However, leveraging on the advances provided by Next Generation Networks, together with the design principles inherent to Service Oriented Architectures and capabilities offered by Service Delivery Platforms, this scenario is about to change. Based on key conceptual entities called enablers, this work aims to change the current scenario. More concretely, this book introduces three distinct but complementary enablers. The Human Enabler provides a real-time context brokerage system capable of securely managing different types of user-related data in a standardized way. The Reasoning Enabler is the result of a welldefined methodology that enables new knowledge to be reasoned, based on previously stored data, by aggregating, correlating and inferring new information about people and their contexts. Lastly, the Session Management Enabler is responsible for abstracting the communication layers. It provides a context-aware multimedia delivery system capable of personalizing and adapting multimedia content according to a set of user and system pre-defined context data or rules, respectively. Altogether, they form the Converged User-Centric Advertising System and introduce new features that address the needs of both users and advertisers.
The business of telecommunications is undergoing a period of change driven by changes in regulation, increasing demands for services and the development of new access technologies. The market structure of telecommunications is evolving rapidly as new and existing players strive to compete in an increasingly volatile market, while the advent of new data services is placing greater demands on the network as operators strive to offer new broadband services. Underpinning much of this change is the access technology itself, not only in the transitional form of copper twisted pairs, but also increasingly through the use of new fibre, radio and copper systems. The dominant cost of most telecommunication networks is the access network itself, which typically can demand up to 80% of the total investment required.
This book presents an overview of the access network and discusses the technologies that are available. It begins with an introductory chapter defining terms and technologies and goes on to discuss each technology in turn, not only from a technology viewpoint but with a view on how it might be best deployed. Chapters are also included on planning systems, network management, DSL, fibre access networks, optical access networks, fixed wireless access, broadband, wireless LANs, UMTS, and SDH in the access network.
The world is charging towards the new network technologies of broadband and 3G, and new application technologies face the challenge of where they can be used. This book takes a pragmatic look at two particular application technologies - location and personalisation - and presents an understanding of the technical and business impact of these technologies. With a combination of overview papers, detailed technical case studies and a deep understanding of actual implementatio of these services within a telecommunications environment, this book will help those wishing to deliver improved services based on these capabilities. Other key topics covered include CRM and content management.
The Internet of Things (IoT) refers to the evolution of the internet as the interconnection not just of computers, but also uniquely identifiable, pervasive embedded devices. Research has estimated there will be nearly 30 billion devices on the Internet of Things within the next decade. The implementation and deployment of the IoT brings with it management challenges around seamless integration, heterogeneity, scalability, mobility, security, and many other issues. This book explores these challenges and possible solutions.
Topics covered include topology control for building scalable energy efficient IoT; a survey of wireless sensor network operating systems; concepts, designs and implementation of wireless sensor network operating systems; OSIRIS - a framework for sensor-based monitoring systems; modeling and tracing events in RFID-enabled supply chains; a new clone detection approach in RFID-enabled supply chains; participatory sensing networks - a paradigm to achieve IoT applications; market structure analysis of the economics of IoT; and IoT and big data applications for urban planning and building smart cities.
This book is essential reading for researchers in academia and industry developing IoT technologies - an interdisciplinary area that brings together researchers in telecommunications, sensor networks, computing and security.
Scientific knowledge grows at a phenomenal pace--but few books have had as lasting an impact or played as important a role in our modern world as The Mathematical Theory of Communication, published originally as a paper on communication theory more than fifty years ago. Republished in book form shortly thereafter, it has since gone through four hardcover and sixteen paperback printings. It is a revolutionary work, astounding in its foresight and contemporaneity. The University of Illinois Press is pleased and honored to issue this commemorative reprinting of a classic.

Mobile biometrics - the use of physical and/or behavioral characteristics of humans to allow their recognition by mobile/smart phones - aims to achieve conventional functionality and robustness while also supporting portability and mobility, bringing greater convenience and opportunity for its deployment in a wide range of operational environments from consumer applications to law enforcement. But achieving these aims brings new challenges such as issues with power consumption, algorithm complexity, device memory limitations, frequent changes in operational environment, security, durability, reliability, and connectivity. Mobile Biometrics provides a timely survey of the state of the art research and developments in this rapidly growing area.
Topics covered in Mobile Biometrics include mobile biometric sensor design, deep neural network for mobile person recognition with audio-visual signals, active authentication using facial attributes, fusion of shape and texture features for lip biometry in mobile devices, mobile device usage data as behavioral biometrics, continuous mobile authentication using user phone interaction, smartwatch-based gait biometrics, mobile four-fingers biometrics system, palm print recognition on mobile devices, periocular region for smartphone biometrics, and face anti-spoofing on mobile devices.
Now part and parcel of everyday life almost everywhere, mobile phones have radically transformed how we acquire and exchange information. Many anticipated that in Africa, where most have gone from no phone to mobile phone, improved access to telecommunication would enhance everything from entrepreneurialism to democratization to service delivery, ushering in socio-economic development.
With Mobile Secrets, Julie Soleil Archambault offers a complete rethinking of how we understand uncertainty, truth, and ignorance by revealing how better access to information may in fact be anything but desirable. By engaging with young adults in a Mozambique suburb, Archambault shows how, in their efforts to create fulfilling lives, young men and women rely on mobile communication not only to mitigate everyday uncertainty but also to juggle the demands of intimacy by courting, producing, and sustaining uncertainty. In their hands, the phone has become a necessary tool in a wider arsenal of pretense—a means of creating the open-endedness on which harmonious social relations depend in postwar postsocialist Mozambique. As Mobile Secrets shows, Mozambicans have harnessed the technology not only to acquire information but also to subvert regimes of truth and preserve public secrets, allowing everyone to feign ignorance about the workings of the postwar intimate economy.
Modern Personal Radio Systems
R.C.V. Macario The Institution of Engineering and Technology, 1996 Library of Congress TK5103.485.M64 1996 | Dewey Decimal 621.3845
This topical book builds upon an earlier IEE text Personal & mobile radio systems, by the same editor, which set out the fundamental issues in a discipline that appeared to have global expansion potential. That potential has now become a reality, and something more than a new edition of the previous book was needed to bring it up to date. This book is completely new, drawing on the experience and the many intensive studies that have been concentrated in this field in the past five years.
The book gives a clear and detailed insight into the fundamental problems and solutions found in modern personal communications: service requirements, coverage problems, multipath interference, cellular architectures and signalling, network management, data and supplementary services, satellite services. In particular it describes the approach of the GSM methodology, as one of the most intensively developed standards, to some of these problems, although the same principles also apply to DCS 1800 and other technologies.
With the rapid progress in networking and computing technologies, a wide variety of network-based computing applications have been developed and deployed on the internet. Flexible and effective service provisioning for supporting the diverse applications is a key requirement for the next generation internet. However, the current internet lacks sufficient capability for meeting this requirement, mainly due to the ossification caused by tight coupling between network architecture and infrastructure. Service-Oriented Architecture (SOA), which has been widely adopted in cloud computing via the Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) paradigms, may be applied in networking to decouple network architecture and infrastructure; thus offering a promising approach to addressing some fundamental challenges to the next generation Internet. In general, such a service-oriented networking paradigm is referred to as Network-as-a-Service (NaaS). This book presents the state of the art of the NaaS paradigm, including its concepts, architecture, key technologies, applications, and development directions for future network service provisioning. It provides readers with a comprehensive reference that reflects the most current technical developments related to NaaS.
Designed for ICT professionals involved in the planning, design, development, testing and operation of network services, this book is ideal for self-teaching. It will help readers evaluate a network situation and identify the most important aspects to be monitored and analysed. The author provides a detailed step by step methodological approach to network design from the analysis of the initial network requirements to architecture design, modelling, simulation and evaluation, with a special focus on statistical and queuing models. The chapters are structured as a series of independent modules that can be combined for designing university courses. Practice exercises are given for selected chapters, and case studies will take the reader through the whole network design process.
The New American Cinema
Jon Lewis Duke University Press, 1998 Library of Congress PN1993.5.U6N47 1998 | Dewey Decimal 384.830973
This collection of essays provides the first comprehensive survey of Hollywood and independent films from the mid-sixties to the present. Deliberately eclectic and panoramic, The New American Cinema brings together thirteen leading film scholars who present a range of theoretical, critical, and historical perspectives on this rich and pivotal era in American cinema. The essays are divided into three sections: "Movies and Money," "Cinema and Culture," and "Independents and Independence." The first section focuses on the economics of the industry and analyzes the connection between the film business and the finished product. Topics include a look at the economic conditions that made the seventies’ auteur renaissance possible, the distribution of studio and independent films, and the recent spate of mergers and acquisitions that have come to characterize the new Hollywood. The second part of The New American Cinema deals with the political and cultural significance of war and Vietnam films (Platoon, Apocalypse Now, Born on the Fourth of July); "male rampage" films (Rambo, Lethal Weapon, Die Hard); women’s psychothrillers (The Silence of the Lambs); special effects pictures (2001: A Space Odyssey, Star Wars); and historical re-presentations (Oliver Stone’s JFK). The final section casts a keen eye on films produced and exhibited outside the commercial mainstream, examining the financial realities of "indie" films; the influence of independent filmmaker John Cassavetes on Coppola, Altman, and Scorsese; the stereotyping of African Americans in mainstream cinema; and the films of independent women filmmakers.
When three deaf men in the 1960s invented and sold TTYs, the first teletypewriting devices that allowed deaf people to communicate by telephone, they started a telecommunications revolution for deaf people throughout America. A New Civil Right: Telecommunications Equality for Deaf and Hard of Hearing Americans chronicles the history of this movement, which lagged behind new technical developments decades after the advent of TTYs.
In this highly original work, Author Karen Peltz Strauss reveals how the paternalism of the hearing-oriented telecommunications industries slowed support for technology for deaf users. Throughout this comprehensive account, she emphasizes the grassroots efforts behind all of the eventual successes. A New Civil Right recounts each advance in turn, such as the pursuit of special customer premises equipment (SCPE) from telephone companies; the Telecommunications Act of 1982 and the Telecommunications Accessibility Enhancement Act of 1988 and the 1990 Americans with Disabilities Act, which required nationwide relay telephone services for deaf and hard of hearing users.
Strauss painstakingly details how all of these advances occurred incrementally, first on local and state levels, and later through federal law. It took exhaustive campaigning to establish 711 for nationwide relay dialing, while universal access to television captioning required diligent legal and legislative work to pass the Decoder Circuitry Act in 1990. The same persistence resulted in the enactment of the Telecommunications Act of 1996, which required all off-the-shelf communications equipment, including new wireless technology, to be readily accessible to deaf users.
Communications policy as been a fertile area for testing theories of regulation, subsidy and incentives, free speech, political participation, and the public interest. The capacities of new communications technology have changed markedly since much of the governing legislation in the communications field was written. Such a change is likely to continue and have considerable impact on specific communications sectors and in communications policy. This two volume set of analyses undertakes a review of telecommunications policy in transition—of actions taken and not taken, of goals pursued or ignored, of the adequacy of policy vehicles and their strengths and weaknesses. The authors evaluate three categories of policy problems: those of concept, scope, and judgment in communications policy; those specific to media industries and forces affecting them; and those concerning wider public policy concerns intersecting with communication.
This book contains a thorough treatment of phase noise, its relationship to thermal noise and associated subjects such as frequency stability. The design of low phase noise signal sources, including oscillators and synthesisers, is explained and in many cases the measured phase noise characteristics are compared with the theoretical predictions. Full theoretical treatments are combined with physical explanations, helpful comments, examples of manufactured equipment and practical tips.
Overall system performance degradations due to unwanted phase noise are fully analysed for radar systems and for both analogue and digital communications systems. Specifications for the acceptable phase noise performance of signal sources to be used in such systems are derived after allowing for both technical and economic optimisation.
The mature engineer whose mathematics may be somewhat rusty will find that every effort has been made to use the lowest level of mathematical sophistication that is compatible with a full analysis and every line of each mathematical argument has been set out so that the book may be read and understood even in an armchair.
Due to a novel approach to the analytical treatment of narrow band noise, the book is simple to understand while simultaneously carrying the analysis further in several areas than any existing publication.
"Inspired." - Publishers Weekly
In 1964, of the more than 85 million telephones in the United States and Canada, less than one percent were used regularly by deaf people. If they didn't ask their hearing neighbors for help, they depended upon their hearing children, some as young as three years old, to act as intermediaries for business calls or medical consultations. In that same year, three enterprising deaf men, Robert H. Weitbrecht, James C. Marsters, and Andrew Saks, started the process that led to deaf people around the world having an affordable phone system that they could use.
Weitbrecht, a successful physicist with the Stanford Research Institute, had been experimenting with a teletypewriter (TTY) used with shortwave radios. When Marsters, a prominent deaf orthodontist, met Weitbrecht and saw his TTY, he immediately suggested the possibility of resolving deaf people's decades-long struggle to have access to telecommunications without relying totally upon hearing people as go-betweens. Andrew Saks brought his business acumen to the group, which soon set to work overcoming the daunting problems they faced.
Harry Lang's A Phone of Their Own: The Deaf Insurrection Against Ma Bell tells how these three men collaborated to solve the technical difficulties of developing a coupling device for TTYs that would translate sounds into discernible letters. More remarkably, and with the help of an expanding corps of Deaf advocates, they successfully assaulted the American Telephone and Telegraph Company (AT&T), which in its efforts to protect its monopoly, smashed old TTYs to keep them from being used for potentially competitive purposes. The Federal Communications Commission (FCC) also resisted efforts to build a telephone system for deaf people that was available, affordable, portable, and fully accessible. Lang recounts in vivid terms how many other Deaf individuals and groups from all walks of life joined Weitbrecht, Marsters, and Saks against these forces. A Phone of Their Own is an entertaining and engrossing story of how they fought and won, and changed the world for the better for deaf people everywhere.
Harry G. Lang is Professor/Research Associate at the Center for Research, Teaching and Learning at the National Technical Institute for the Deaf in Rochester, NY.
Free Space Optical (FSO) Communication uses light propagation in free space (air, outer space, and vacuum) to wirelessly transmit data for telecommunications and communication networking. FSO Communication is a key wireless and high-bandwidth technology for high speed large-capacity terrestrial and aerospace communications, which is often chosen as a complement or alternative to radio frequency communication. The propagating optical wave can be influenced negatively by random atmospheric changes such as wind speed, temperature, relative humidity, and pressure, thermal expansion, earthquakes, and high-rise buildings. This edited book covers the principles, challenges, methodologies, techniques, and applications of Free Space Optical Communication for an audience of engineers, researchers, scientists, designers, and advanced students.
The term 'teletraffic engineering' has been used since the early days of the century to describe the design of switched telecommunications networks in terms of probabilities. More recent advances in queuing theory, and the growing realisation that the basic techniques can be applied to many other aspects of system design, has led to an extension of the subject and to the term 'performance engineering'.
This book describes the basic theory of performance engineering and its application to both circuit- and packet-switched systems. For the increasing number of systems that are too complex to be analysed by theoretical methods, an introduction is given to simulation techniques. Other applications such as reliability, tolerances and the system implications of radio fading are covered, and the principles of design are discussed in terms of the basic theory.
Final-year undergraduate and postgraduate students will find the text useful in relation to a wide range of systems, as will practising telecommunication engineers. The book will also be of interest to telecommunication managers who are more interested in system performance than in detailed hardware and software design.
From all sides, we hear that computer technology, with its undeniable power to disseminate information and connect individuals, holds enormous potential for a reinvigoration of political life. But will the Internet really spark a democratic revolution? And will the changes it brings be so profound that past political thought will be of little use in helping us to understand them?
In Prometheus Wired, Darin Barney debunks claims that a networked society will provide the infrastructure for a political revolution and shows that the resources we need for understanding and making sound judgments about this new technology are surprisingly close at hand. By looking to thinkers who grappled with the relationship of society and technology, such as Plato, Aristotle, Marx, and Heidegger, Barney critically examines such assertions about the character of digital networks.
Along the way, Barney offers an eye-opening history of digital networks and then explores a wide range of contemporary issues, such as electronic commerce, telecommuting, privacy, virtual community, digital surveillance, and the possibility of sovereign governance in an age of global networks. Ultimately, Barney argues that instead of placing power back in the hands of the public, a networked economy seems to exacerbate the worst features of industrial capitalism, and, in terms of the surveillance and control it exerts, reduces our political freedom.
Of vital interest to politicians, communicators, and anyone concerned about the future of democracy in the digital age, Prometheus Wired adds a provocative new voice to the debate swirling around "the Net" and the ways in which it will, or will not, change our political lives.
Vast numbers of radio systems are now in use, and with new users and new uses constantly emerging, these systems have the potential to interfere with each other.
National agencies are empowered to control the use of radio to ensure that systems within their jurisdiction do not disrupt each other's services. Interference may also arise between radio systems operating in different countries. An elaborate code of regulations has been agreed, under the aegis of the International Telecommunication Union, to facilitate cooperation between the national agencies to control interference across frontiers. The Union also provides the global forum for the standardisation of radio systems where this has been found to be desirable.
For some kinds of radio system, especially broadcasting and land mobile radio, governments may also find it necessary to determine which of the organisations competing to provide radio facilities for public use should be licensed and which should not. This process is known as regulation.
Intended as a handbook for administrators and engineers, this book reviews the processes of interference management, regulation of competing service providers and system standardisation for the control and use of the radio spectrum. At a time when telecommunication services and broadcasting are being liberalised in many countries, this book will also provide new operators of radio facilities, private and public, with valuable insights into the regulatory process.
The history of cable television in America is far older than networks like MTV, ESPN, and HBO, which are so familiar to us today. Tracing the origins of cable TV back to the late 1940s, media scholar John McMurria also locates the roots of many current debates about premium television, cultural elitism, minority programming, content restriction, and corporate ownership.
Republic on the Wire takes us back to the pivotal years in which media regulators and members of the viewing public presciently weighed the potential benefits and risks of a two-tiered television system, split between free broadcasts and pay cable service. Digging into rare archives, McMurria reconstructs the arguments of policymakers, whose often sincere advocacy for the public benefits of cable television were fueled by cultural elitism and the priority to maintain order during a period of urban Black rebellions. He also tells the story of the people of color, rural residents, women’s groups, veterans, seniors, and low-income viewers who challenged this reasoning and demanded an equal say over the future of television.
By excavating this early cable history, and placing equality at the center of our understanding of media democracy, Republic on the Wire is a real eye-opener as it develops a new methodology for studying media policy in the past and present.
Resilience in Wireless Networks is the first book to cover this topic at an advanced level. It provides a unified view of the latest research and illustrates the issues, challenges and solutions currently under discussion. The book divides wireless networks into infrastructure and ad hoc topologies and considers the resilience of each separately.
This is an academic monograph with some mathematical analysis and numerical examples, with an emphasis on concepts and generalisation rather than specific software tools or implementation aspects. It also contains practical examples of real-life attacks and diagnostic tools to improve future resilience of networks.
Resilience in Wireless Networks is an essential reference for researchers and professionals in IT security and resilience.
Satellite Communication Systems
B.G. Evans The Institution of Engineering and Technology, 1999 Library of Congress TK5104.S3627 1999 | Dewey Decimal 621.38254
This updated and extended new edition has been compiled from the course material of the highly successful IEE Vacation School of the same name. The vacation school was designed to give a broad introduction to the subject of satellite communications and provide the background knowledge and tools of the trade for those entering the field. The 3rd edition of the book continues this theme and up-to-date information on mobile and personal satellite constellations, navigation and positioning, and military and small satellite systems has been added, as well as a look to future Ka-band multimedia systems. We have also included updated ITU information and sections on history, organisation and the satellite business. The book differs from others on the subject in its pragmatic and engineering-oriented approach. The contributors are all current practitioners from industry or academics specialising in the field.
The book is ideal for undergraduate or postgraduate students and practising engineers meeting the subject for the first time. However, it also providers the breadth and detail that make it suitable as a reference text.
Satellite communications (SatCom) plays a vital role in ensuring seamless access to telecommunications services anytime, and is a viable option for delivering telecommunication services in a wide range of sectors such as aeronautical, military, maritime, rescue and disaster relief. It should be an important component of 5G-and-beyond wireless architectures as it can complement terrestrial telecommunication solutions in various scenarios to provide highly reliable and secure connectivity over a wide geographical area. This book explores promising scenarios for 5G SatCom, novel paradigms for hybrid/integrated satellite-terrestrial integration, and emerging technologies for the next generation of SatCom systems. Topics covered include: Role of SatCom in the 5G Era; 5G satellite use cases and scenarios; SDN-enabled networks, NFV-based scenarios and on-board processing for satellite-terrestrial integration; EHF broadband aeronautical SatCom systems; Next-generation NGSO SatCom systems; Diversity combining and handover techniques for MEO satellites; Non-linear countermeasures for multicarrier satellites; SDN demonstrator for multi-beam satellite precoding; Beam-hopping SatCom systems; Optical on-off keying data links for LEO downlink applications; Ultra-high speed data relay systems; On-board interference detection and localization; Advanced random access schemes for SatCom systems; Interference avoidance, mitigation and dynamic spectrum sharing for hybrid satellite-terrestrial systems; and Two-way satellite relaying.
Security for Mobility
Chris J. Mitchell The Institution of Engineering and Technology, 2004 Library of Congress QA76.9.A25S433 2004 | Dewey Decimal 005.8
Over the last two decades, mobile telecommunications has grown dramatically, from a small niche technology to a massive industry. Mobile telephones are now ubiquitous, and the divisions between PCs, PDAs, mobile telephones and other mobile devices are becoming increasingly blurred. Against this background, the security of information of both the devices themselves, and the information handled by these devices, is becoming ever more important.
Security for Mobility pulls together up to the minute research from an international group of academics and professionals working in industry. The main text of the book is divided into five parts - underlying technologies; network security; mobile code issues; application security; and the future. Each chapter of the book is the collaboration of different authors, including many of the leading European experts currently working within the field. Thus each chapter is self-contained and can be read independently, although there are many relationships between the various chapters.
The book will be of interest to engineers and computer scientists working in security-related aspects of the communications, computing and telecommunications industries, as well as postgraduate students and academics working within these fields.
The contributors to Signal Traffic investigate how the material artifacts of media infrastructure--transoceanic cables, mobile telephone towers, Internet data centers, and the like--intersect with everyday life. Essayists confront the multiple and hybrid forms networks take, the different ways networks are imagined and engaged with by publics around the world, their local effects, and what human beings experience when a network fails.
Some contributors explore the physical objects and industrial relations that make up an infrastructure. Others venture into the marginalized communities orphaned from the knowledge economies, technological literacies, and epistemological questions linked to infrastructural formation and use. The wide-ranging insights delineate the oft-ignored contrasts between industrialized and developing regions, rich and poor areas, and urban and rural settings, bringing technological differences into focus.
Contributors include Charles R. Acland, Paul Dourish, Sarah Harris, Jennifer Holt and Patrick Vonderau, Shannon Mattern, Toby Miller, Lisa Parks, Christian Sandvig, Nicole Starosielski, Jonathan Sterne, and Helga Tawil-Souri.
Spectrum and Network Measurements
Robert A. Witte The Institution of Engineering and Technology, 2001 Library of Congress TK7879.4.W58 2001 | Dewey Decimal 621.381548
This book covers the theory and practice of spectrum and network measurements in electronic systems. Intended for readers who have a background in electrical engineering and use spectrum or network analyzers to characterize electronic signals or systems, this classic volume successfully consolidates the pertinent theory into one comprehensive treatment of frequency domain measurements. Witte's thorough coverage of critical concepts, such as Fourier analysis, transmission lines, intermodulation distortion, signal-to-noise ratio and S-parameters enables the reader to understand the basic theory of signals and systems, relate it to measured results, and apply it when creating new designs.
The book is devoted to advanced radiocommunication, discussing the merits and operational aspects of spread spectrum signalling. Spread spectrum modulation is emerging as one of the most important tools for combatting a wide range of problems usually encountered in radiocommunication. For military applications the signalling is able to resist difficulties deliberately introduced by an enemy, such as jamming and eavesdropping. For civil application, the efficient signal multiplexing and multipath rejection capability is of great interest. The price paid however is the need for very complex processing of the radio signals. This task put great challenges on new technologies and design, and it is only recently that operational systems have started to emerge from the laboratories.
The book starts by comparing spread spectrum modulation and conventional modulation methods, and then discusses demodulation, which requires both special acquisition and synchronisation techniques. The electronic warfare scenario is introduced, discussing the principles of various spreading techniques and possible countermeasures. The coding for bandwidth spreading in a direct sequence spread spectrum system is treated by discussing the most common codes and their different figures of merit with respect to multipath, code division multiplexing and signal concealment. The book also illustrates the possible benefits, as well as limits to the use of new hardware technology to accomplish the various functions necessary for successful operation of a spread spectrum system. The effect of the propagation environment on spread spectrum is treated both analytically and through reported experiments and simulations. Finally the book considers the task of designing a complete communication network and discusses the usefulness and technology for additional interference suppressing techniques suitable to work with spread spectrum systems.
Mobile communication is one of the most important applications in the tele-communications and IT field. Developments in technology are enabling the design of advanced mobile radio networks linking information processing and data routing, with the radio segment sandwiched between layers of digital signal processors. Spread spectrum technology adapts radio communication to computational data information processing networks.
This book presents the concepts of modern mobile communication and discusses the user requirements and operational environment which influence mobile systems design. Its focus is on the mobility issues for a decentralised network topology and the effects of spread spectrum modulation on radios used in packet-switched networks. Connecting radio terminals using packet switching gives a highly flexible and efficient solution for mobile users, and the book gives considerable space to discussing packet switching in radio networks, protocols and routing strategies. Providing vital information for all those in the mobile systems field, the book is supported by detailed case study information to illustrate the practical issues involved in implementing the technology.
A substantially updated edition of Video Coding: An introduction to standard codecs (IEE 1999, winner of IEE Rayleigh Award as the best book of 2000), this book discusses the growth of digital television technology, from image compression to advanced video coding. This third edition also includes the latest developments on H.264/MPEG-4 video coding and the scalability defined for this codec, which were not available at the time of the previous edition (IEE 2003). The book highlights the need for standardisation in processing static and moving images and extensively exploits the ITU and ISO/IEC standards defined in this field. The book gives an authoritative explanation of pictures and video coding algorithms, working from basic principles through to the advanced video compression systems now being developed. It discusses the reasons behind the introduction of a standard codec for a specific application and its chosen parameters. Each chapter is devoted to a standard video codec, and chapters are introduced in an evolutionary manner complementing the earlier chapters. This book will enable readers to appreciate the fundamentals needed to design a video codec for any given application and should prove a valuable resource for managers, engineers and researchers working in this field.

Telecommunications is vital to modern life, and the global telecommunication network that has developed is an essential part of the infrastructure of society. Although there is an extensive literature on many aspects of telecommunication technology, comparatively little has been published on the functioning and planning of complete telecommunication networks. The first edition of this book was intended to help fill that gap and this new edition has been thoroughly revised and includes much new material.
The initial chapters describe the structure of local, national and international networks, and cover switching systems, transmission systems, signalling, numbering schemes, routeing ard call charging. The principles of traffic engineering, mobile networks, ISDN, ATM, intelligent networks, network management, investment appraisal and network planning are also explained. Although the book mainly deals with public telephone networks, there is also a chapter on private networks and data networks. Finally, the principles explained in the earlier chapters are illustrated by several case studies on network planning.
The book is intended both to provide the young engineer with a general knowledge of telecommunications and to give the experienced specialist a deeper understanding of his/her own work against the background of the complete telecommunication network. The book evolved from IEE vacation schools at Aston University, and the chapters are mainly based on teaching contributions made by the authors at these schools.
Telecommunications Network Modelling, Planning and Design addresses sophisticated modelling techniques from the perspective of the communications industry and covers some of the major issues facing telecommunications network engineers and managers today. Topics covered include network planning for transmission systems, modelling of SDH transport network structures and telecommunications network design and performance modelling, as well as network costs, ROI modelling and QoS in 3G networks. This practical book will prove a valuable resource to network engineers and managers working in today's competitive telecommunications environment.
Service quality and cost control are critical success factors for the communications industry and performance engineering is vital in achieving both. It enables service quality to be 'built in' to products; cost control is achieved by addressing potential problems at an early stage, before the costs to remedy problems rise and large failure costs are incurred.
Telecommunications Performance Engineering includes both introductory material, giving a comprehensive overview of the subject area, and in-depth case studies illustrating the latest tools and techniques. Performance engineering throughout the whole life-cycle is discussed, including modelling, measurement, testing and capacity management. In addition, the book covers cutting-edge information and technology on the designs used to protect the performance levels of overloaded networks. A wide range of system and network applications are covered, from broadband, IP networks, and intelligent networks providing telemarketing services to combined Web/telephony systems, operational support systems and call centres. This book is essential reading for communications managers, designers, performance engineers and students.
In today's increasingly competitive communications environment, Quality of Service (QoS) is of paramount importance in the battle to win market share. However, the enhanced expectations of customers and the introduction of many new services and technologies makes comprehending and meeting customer requirements a real challenge. Building on the issues covered in Quality of Service in Telecommunications (1997), this book examines the technical, service and human issues that need to be addressed in order to provide a level of QoS that will meet those requirements. One key objective is to increase the reader's understanding of the importance of QoS and to show how the concepts presented can be applied to the reader's own circumstances. The book provides a comprehensive overview of definitions and standards, frameworks and models, network performance, internet, mobile and satellite services, the impact on customers, external drivers, economics, fraud and security and future trends. The authors, established experts in their fields, have wide-ranging experience in both UK and US telecommunications companies, reflecting the global nature of this industry and the universal concept of QoS.

Telecommunications Regulation examines the background to regulation and the work of the regulator. It discusses typical regulatory rules and the legal and administrative framework for regulation, and looks at regulatory strategies, market structures and approaches to price control. The book includes a number of case studies which show how regulators engage with such topical issues as interconnection and loop unbundling, and also features technical coverage of both numbering and number portability. Finally, it looks at new products and services such as virtual network operators, intelligent networks, radio spectrum and next generation networks, and considers the impact these might have on the future of regulation.
A comprehensive, in-depth guide to the subject, this book will be a valuable resource for engineers and managers in the industry, as well as lawyers and economists needing an insight into current telecommunications regulation.

As the Information Age evolves, customers need communications of high quality, excellent value and widespread mobility. The response is to establish efficient networks carrying a wide range of services. Signalling is at the heart of this revolution, energising networks to meet customer expectations.
This book gives an introduction to the principles of signalling systems along with an in-depth examination of their architecture. Modern signalling systems are described in detail, including Signalling System No.7 and the Digital Subscriber Systems, while older systems are outlined in the appendices. Chapters are devoted to signalling for mobile networks, intelligent networks and private networks. Signalling interworking, the role in network management and meeting broadband requirements are also covered. Internet technologies are coming to the fore and a chapter explains some common Internet Protocols and highlights the striking similarities with telecommunications systems. The glossary and list of abbreviations cut through the maze of jargon.
The book will appeal to a wide range of readership. Reading the chapters in sequence will provide a comprehensive description of signalling. Communications experts will find the chapter summaries useful in selecting appropriate text. Experts in specialised areas of signalling can use the book to expand their range of knowledge.
This book has been written with the intention of helping those who ore concerned with planning, ordering, managing and using telecommunications facilities in connection with their business activities, and who do not wish to obtain a detailed technical and mathematical knowledge of the subject. The various types of telecommunications traffic are analysed without recourse to the underlying theory, and the reader is introduced to the terminology and operation of modern telecommunications systems and networks. Particular attention is paid to the relationship between traffic-carrying capacity and cost, and to the importance of traffic measurement and forecasting as a means of matching equipment provision to demand. The role of performance targets is discussed and the book explains how a comparison between public-network tariff options and the cost of private system and network alternatives can ensure a cost-effective solution to any communications problem. The principles are demonstrated by simple worked examples and a detailed glossary of terms is included.
Now in its 3rd edition, this successful book provides an intuitive approach to transceiver design, allowing a broad spectrum of readers to understand the topics clearly. It covers a wide range of data link communication design techniques, including link budgets, dynamic range and system analysis of receivers and transmitters used in data link communications, digital modulation and demodulation techniques of phase-shift keyed and frequency hopped spread spectrum systems using phase diagrams, multipath, gain control, an intuitive approach to probability, jamming reduction method using various adaptive processes, global positioning systems (GPS) data link, and direction-finding and interferometers, plus a section on broadband communications and home networking. Various techniques and designs are evaluated for modulating and sending digital data. Thus readers gain a firm understanding of the processes needed to effectively design wireless data link communication systems.

How did the telegraph, a new and revolutionary form of communication, affect diplomats, who tended to resist change? In a study based on impressive multinational research, David Paull Nickles examines the critical impact of the telegraph on the diplomacy of the nineteenth and early twentieth centuries.
Case studies in crisis diplomacy--the War of 1812, the Trent affair during the U.S. Civil War, and the famous 1917 Zimmermann telegram--introduce wide-ranging thematic discussions on the autonomy of diplomats; the effects of increased speed on decision making and public opinion; the neglected role of clerks in diplomacy; and the issues of expense, garbled text, espionage, and technophobia that initially made foreign ministries wary of telegraphy. Ultimately, the introduction of the telegraph contributed to the centralization of foreign ministries and the rising importance of signals intelligence. The faster pace of diplomatic disputes invited more emotional decisions by statesmen, while public opinion often exercised a belligerent influence on crises developing over a shorter time period.
Under the Wire offers a fascinating new perspective on the culture of diplomacy and the social history of technology.

Reviews of this book: David Paull Nickles has plumbed the archives of four countries to determine just how transformative [the invention of the telegraph] really was. Under the Wire is a subtle and impressive examination of history. --Christian D. Brose, Wall Street Journal
In this study of the impact of telegraphy on the management of international relations, the reader is rewarded time and again by finding original observations regarding familiar events. This is a book that can have a shaping effect not only on the field of international relations but on many others, since it compels one to think hard about how changes in technology affect behavior and thought among groups with deeply rooted traditions and beliefs. --Ernest R. May, Harvard University
We all enjoy the benefits of the 'information age' but we may not be aware of the range of technologies and infrastructure that underpins the Internet and the services that it supports. There are many companies involved in the business of providing and operating such resources. This book attempts to explain the complex interplay between the companies, how their businesses operate, and how they seek to make a profit.
The authors consider how telecommunications companies tackle the challenging Information and Communication Technology market place - how they make a case for investment, develop and market products, and how they operate telecommunications networks and computer-server resources. Topics covered include: an introduction to the telecommunications business; regulation; business strategy; corporate finance and governance; network economics; network strategy and planning; customers and marketing; product management; network and service operations; and people and organisation development. In particular, this book provides a comprehensive introduction to the tools for analysing markets, constructing business cases and providing customer service - all with specific reference to telecommunications and reallife case studies.
The authors have based this book on the material used to teach Masters Degree students over the last 10 years, as well as drawing on their knowledge gained through a combined experience of over 80 years working within the industry. Understanding Telecommunications Business is essential for undergraduate and graduate students studying telecommunications, and will also find a place on the bookshelves of the many people already working in the industry, or considering joining it. Although selfcontained, this book forms a companion to Understanding Telecommunications Networks, which is also in the IET Telecommunications series.
A telecommunications network is an electronic system of links, nodes and the controls that govern their operations to allow voice and data transfer among users and devices. Examples of telecommunications networks are the telephone networks, computer networks and the Internet. Understanding Telecommunications Networks provides a comprehensive explanation of how various systems and technologies link together to construct fixed and mobile telecommunications networks and provide services. It uses straightforward language supported by block-schematic diagrams so that non-engineers and engineers alike can learn about the principles.
This fully revised, updated and expanded second edition covers all aspects of today's networks, including how they are planned, formed and operated. After an introductory chapter on telephony, the book describes all of today's networks and considers how they link. Individual chapters then consider the principles, technologies and network structures relating to network components; transmission systems and networks; circuit switching systems and networks; signalling and control; data (packet) switching and routeing; and mobile systems and networks. The book concludes with a chapter designed to pull everything together, considering architecture, quality of service and performance, operations, network evolution and next generation networks. This is a companion volume to Understanding Telecommunications Business authored by Andy Valdar & Ian Morfett (ISBN: 9781849197458).
This book explains how telecommunications networks work. It uses straightforward language supported by copious block-schematic diagrams so that non-engineers and engineers alike can learn about the principles of fixed and mobile telecommunications networks carrying voice and data. The book covers all aspects of today's networks, including how they are planned, formed and operated, plus next generation networks and how they will be implemented.
After an introductory chapter on telephony the book briefly describes all of today's networks – PSTN, mobile, cable television, the Internet, etc. – and considers how they interconnect. Individual chapters then consider the principles, technologies and network structures relating to transmission, circuit switching, signalling and control, data (including voice-over-IP) networks, and mobile networks. The important subject of numbering and addressing for telephony and IP is then covered. The book concludes with a chapter designed to pull everything together, considering architecture, quality of service and performance, operations and network evolution.
Despite the rapid changes taking place in telecommunications today - covering customer expectations, commercial arrangements, regulation, markets and services, as well as technology - this book's coverage of the basic principles makes it a helpful and enduring reference for undergraduate and postgraduate students, and for professionals working in the industry.
The interplay of privacy, security and user-determination is an important consideration in the roll-out of biometric technologies. It brings into play requirements such as privacy of biometric data in systems, communication and databases, soft biometric profiling, biometric recognition of persons across distributed systems and in nomadic scenarios, and the convergence between user convenience, usability and authentication reliability.
User-Centric Privacy and Security in Biometrics explores how developments in biometrics will address security and privacy aspects. The book surveys and evaluates how biometric techniques can enhance and increase the reliability of security strategies in a variety of applications. This includes privacy-preserving state-of-the-art works and future directions in the view of biometrics as part of broader security concepts. The fundamental emphasis is on privacy within and for biometrics, particularly for the protection of biometric data, informed consent of data usage, transparency on biometric data, and big data fraud prevention.
One of the most significant developments in telecommunications in the last decade, the very small aperture terminal (VSAT), as part of a satellite communications network, is the culmination of technology that allows earth terminals to be located on users' premises to provide data, voice and even video services. Networks based on VSATs can be established rapidly and reconfigured to respond to changing communications needs in a flexible and cost-effective manner.
In 28 chapters written by individuals who have made major contributions to the VSAT scene, Very Small Aperture Terminals describes the key technology underlying these systems, representative systems from leading vendors, link budgets, system protocols, data distribution based on television broadcasting, service provision, economic and, perhaps most importantly, regulatory issues.
Very Small Aperture Terminals is essential reading for anyone involved in telecommunications systems management or the engineering aspects, from equipment manufacturers to those who will use the systems. The technology and systems chapters will be of interest to practising engineers and postgraduate engineering students who require an introduction to the subject. Those with responsibilities for licensing and regulation will find their functions put into context.
Digital video compression has revolutionised the broadcast industry. Its implementation has been the vital key to the expansion of video via satellite, cable, internet and terrestrial TV. However, new technologies not only enable new applications, they also create new challenges such as how to measure video quality, and how to maintain video quality in concatenated compression systems.
Video Compression Systems provides an overview on many issues concerning today's complex digital video systems: from video quality measurements to statistical multiplexing, from pre-processing to transcoding and concatenation. It explains video compression systems from first principles and gives a detailed summary of currently used MPEG standards, as well as non-MPEG algorithms. Furthermore, it provides a summary of motion estimation algorithms and explains processing priorities for mobile applications, HDTV, contribution and distribution systems, as well as for end user systems.
Video Compression Systems focuses intentionally on the principles rather than the mathematics in order to make it more readable and accessible to a wider audience. It is aimed at senior undergraduate students taking modules in video technologies, multimedia processing or video compression, as well as television engineers working on video compression systems.

Voice over Internet Protocol (VoIP) has recently evolved from a simple capability for transporting voice communications into a much more powerful technology capable of changing the way voice applications are constructed, delivered, marketed and sold. Whilst VoIP has clearly provided a focus for much debate within the telecommunications industry, there has been a clear gulf between hype and reality. However the questions now being asked have migrated from 'Will it work?' to 'What will the industry look like when it is delivered at scale?'
In Voice over IP: systems and solutions, Richard Swale has brought together key contributors from within the BT Group and externally, to cover all of the important issues surrounding telephony over IP networks. This authoritative book examines VoIP as a technology and its consideration within the industry, the motivations for VoIP networks, a review of the status of the major components of a VoIP network and their development, and both current and emerging applications. VoIP technology blurs the boundaries between fixed, mobile and multimedia communications and the implications are explored and discussed.
The primary market for this comprehensive book is telecommunications engineers and developers, service providers and regulators. However, all those with a technical or business interest in this rapidly developing area of communications technology will also find this book highly relevant.
This book bridges the worlds of the economist, the engineer, the regulator and the manager. It outlines the technology of the subject in sufficient detail to provide an understanding of the industry's economics, and presents a comprehensive picture of the markets into which its products and services are sold.
Service supply monopolies are dissolving under the combined pressures of technological change, managerial inventiveness and regulation, leading the industry into uncharted waters. Competition is appearing in the local loop. International telecommunications services have been among the fastest to change, both technologically and in market structure. These developments, along with resale operations and their associated cost structures are analysed, as are the comparative advantages of satellite and cable systems.
There are good economic reasons for optimism about what these changes will bring, not least in more efficient pricing and resource allocation, but important matters of public welfare are at stake, and these too are discussed.
Examples and statistics are drawn across the full range of the world's nations, offering insights which may be missed when concentrating on the rich countries alone. While the book is of most value to industry professionals, the clarity of its analysis makes it useful to anyone with a business or academic interest in telecommunications
