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.
Communications: An international history of the formative years traces the evolution of communications from 500 BC, when fire beacons were used for signalling, to the 1940s, when high definition television systems were developed for the entertainment, education and enlightenment of society. The book does not simply provide a chronicle of dates and events, nor is it a descriptive catalogue of devices and systems. Rather, it discusses the essential factors - technical, political, social, economic and general - that enabled the evolution of modern communications. The author has taken a contextual approach to show the influence of one discipline upon another, and the unfolding story has been widely illustrated with contemporary quotations, allowing the progress of communications to be seen from the perspective of the times and not from the standpoint of a later generation.
“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.
Down to Earth presents the first comprehensive overview of the geopolitical maneuvers, financial investments, technological innovations, and ideological struggles that take place behind the scenes of the satellite industry. Satellite projects that have not received extensive coverage—microsatellites in China, WorldSpace in South Africa, SiriusXM, the failures of USA 193 and Cosmos 954, and Iridium—are explored. This collection takes readers on a voyage through a truly global industry, from the sites where satellites are launched to the corporate clean rooms where they are designed, and along the orbits and paths that satellites traverse. Combining a practical introduction to the mechanics of the satellite industry, a history of how its practices and technologies have evolved, and a sophisticated theoretical analysis of satellite cultures, Down to Earth opens up a new space for global media studies.
Empires of Entertainment integrates legal, regulatory, industrial, and political histories to chronicle the dramatic transformation within the media between 1980 and 1996. As film, broadcast, and cable grew from fundamentally separate industries to interconnected, synergistic components of global media conglomerates, the concepts of vertical and horizontal integration were redesigned. The parameters and boundaries of market concentration, consolidation, and government scrutiny began to shift as America's politics changed under the Reagan administration. Through the use of case studies that highlight key moments in this transformation, Jennifer Holt explores the politics of deregulation, the reinterpretation of antitrust law, and lasting modifications in the media landscape.
Holt skillfully expands the conventional models and boundaries of media history. A fundamental part of her argument is that these media industries have been intertwined for decades and, as such, cannot be considered separately. Instead, film, cable and broadcast must be understood in relation to one another, as critical components of a common history. Empires of Entertainment is a unique account of deregulation and its impact on political economy, industrial strategies, and media culture at the end of the twentieth century.
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.
In Haunted Media Jeffrey Sconce examines American culture’s persistent association of new electronic media—from the invention of the telegraph to the introduction of television and computers—with paranormal or spiritual phenomena. By offering a historical analysis of the relation between communication technologies, discourses of modernity, and metaphysical preoccupations, Sconce demonstrates how accounts of “electronic presence” have gradually changed over the decades from a fascination with the boundaries of space and time to a more generalized anxiety over the seeming sovereignty of technology. Sconce focuses on five important cultural moments in the history of telecommunication from the mid-nineteenth century to the present: the advent of telegraphy; the arrival of wireless communication; radio’s transformation into network broadcasting; the introduction of television; and contemporary debates over computers, cyberspace, and virtual reality. In the process of examining the trajectory of these technological innovations, he discusses topics such as the rise of spiritualism as a utopian response to the electronic powers presented by telegraphy and how radio, in the twentieth century, came to be regarded as a way of connecting to a more atomized vision of the afterlife. Sconce also considers how an early preoccupation with extraterrestrial radio communications tranformed during the network era into more unsettling fantasies of mediated annihilation, culminating with Orson Welles’s legendary broadcast of War of the Worlds. Likewise, in his exploration of the early years of television, Sconce describes how programs such as The Twilight Zone and The Outer Limits continued to feed the fantastical and increasingly paranoid public imagination of electronic media. Finally, Sconce discusses the rise of postmodern media criticism as yet another occult fiction of electronic presence, a mythology that continues to dominate contemporary debates over television, cyberspace, virtual reality, and the Internet. As an engaging cultural history of telecommunications, Haunted Media will interest a wide range of readers including students and scholars of media, history, American studies, cultural studies, and literary and social theory.
It’s common wisdom that the U.S. economy has continued to thrive despite the loss of industry because of the booming information sector, with high-paying jobs for everything from wireless networks to video games. We are told we live in the Information Age, in which communications networks, and media and information services drive the larger economy. While the Information Age may have looked sunny in the beginning, as it has developed it looks increasingly ominous: its economy and benefits grow more and more centralized-and in the United States, it has become less and less subject to democratic oversight.
Companies around the world have identified the value of information, and are now seeking to control its production, transmission, and consumption. In How to Think about Information, Dan Schiller explores the ways information has been increasingly commodified as a result, and how it both resembles and differs from other commodities. Through a linked series of theoretical, historical, and contemporary studies, Schiller reveals this commodification as both dynamic and expansionary, but also deeply conflicted and uncertain. He examines the transformative political and economic changes occurring throughout the informational realm, and analyzes key dimensions of the process, including the build-up of new technological platforms, the growth of a transnationalizing culture industry, and the role played by China as it reinserts itself into an informationalized capitalism.
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.
Christopher Beauchamp debunks the myth of Alexander Graham Bell as the telephone’s sole inventor, exposing that story’s origins in the arguments advanced by Bell’s lawyers during fiercely contested battles for patent monopoly. The courts anointed Bell father of the telephone—likely the most consequential intellectual property right ever granted.
Latinas on the Line provides a compelling analysis and historical and theoretical grounding of the oral histories, never before seen, of Latina information workers in the Bell System from their entrance in 1973 to their retirements by 2015. Author Melissa Villa-Nicholas demonstrates the importance of Latinas of the field of telecommunications through their own words and uses supporting archival research to provide an overview of how Latinas engage and remember a critical analysis of their work place, information technologies, and the larger globalized economy and shifting borderlands through their intersectional identities as information workers. The book offers a rich and engaging portrait of the critical history of Latinas in telecommunications, from their manual to automated to digitized labor.
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.
On a daily basis we are confronted with "more speech, not less"—more news reports, more television channels, more publications, more electronic communications. Communications laws have expanded in response to the proliferation of communications, and these laws affect everyone.
Communications lawyer Mark Sableman uses recent case studies, practical examples, and plain language to describe and analyze the broad spectrum of modern communications laws and policies. In these essays, Sableman helps communications professionals as well as informed citizens understand the law.
The constitutional foundation for the information age is settled: radical solutions on either side have been rejected. Neither First Amendment absolutism nor untrammeled content-based censorship will rule in America. But within the remaining middle area, many key policy choices are being made by courts and policy makers. Intricate webs of legal do’s and don’ts, practical pitfalls, and effective safe harbors are being developed across the broad spectrum of communications law.
In this guide to existing law, developing trends, and critical policy determinations, Sableman discusses privacy, Internet communications and policy, censorship, libel and slander, copyright and intellectual property, advertising, broadcasting, and journalistic confidentiality. Through actual cases and practical examples, he examines and explains both the existing rules for communications professionals and the developing policies that deserve the attention and scrutiny of informed citizens. Sableman approaches these subjects as a practicing lawyer experienced in both business and media communications.
The phrase "more speech, not less" describes not only the growing cacophony of the information age, but also one approach to legal policy—Justice Louis D. Brandeis’s preference for "more speech, not enforced silence" in all but the most extreme situations. Drawing from his strong advocacy of free speech, Sableman hopes to stimulate informed debate among all who are concerned about the power of information and the magic of words and images.
The telegraph and the telephone were the first electrical communications networks to become hallmarks of modernity. Yet they were not initially expected to achieve universal accessibility. In this pioneering history of their evolution, Richard R. John demonstrates how access to these networks was determined not only by technological imperatives and economic incentives but also by political decision making at the federal, state, and municipal levels.
In the decades between the Civil War and the First World War, Western Union and the Bell System emerged as the dominant providers for the telegraph and telephone. Both operated networks that were products not only of technology and economics but also of a distinctive political economy. Western Union arose in an antimonopolistic political economy that glorified equal rights and vilified special privilege. The Bell System flourished in a progressive political economy that idealized public utility and disparaged unnecessary waste.
The popularization of the telegraph and the telephone was opposed by business lobbies that were intent on perpetuating specialty services. In fact, it wasn’t until 1900 that the civic ideal of mass access trumped the elitist ideal of exclusivity in shaping the commercialization of the telephone. The telegraph did not become widely accessible until 1910, sixty-five years after the first fee-for-service telegraph line opened in 1845.
Network Nation places the history of telecommunications within the broader context of American politics, business, and discourse. This engrossing and provocative book persuades us of the critical role of political economy in the development of new technologies and their implementation.
This compelling new interdisciplinary study investigates the scientific and cultural roots of contemporary conceptions of the network, including computer information systems, the human nervous system, and communications technology. Laura Otis, neuroscientist, literary scholar, and recent recipient of a MacArthur Fellowship, demonstrates that the image of the network is centuries old; it is by no means a modern notion. Placing current comparisons of nerve and computer networks in perspective, Otis explores early analogies linking nerves and telegraphs and demonstrates the influence that nineteenth-century neurobiologists, engineers, and fiction writers influenced each other's ideas about communication.
The interdisciplinary sweep of this book is impressive. Otis focuses simultaneously on literary works by such authors as George Eliot, Bram Stoker, Henry James, and Mark Twain and on the scientific and technological achievements of such pioneers as Luigi Galvani, Hermann von Helmholtz, Charles Babbage, Samuel Morse, and Werner von Siemens.
This unique juxtaposition of physiology, engineering, and literature reveals the common thoughts shared by writers in widely diverse fields and suggests that our current comparisons of nerve and computer networks may not only enhance but shape our understanding of both neurobiology and technology.
Highly accessible and jargon-free, Networking will appeal to general readers as well as to scholars in the fields of interdisciplinary studies, nineteenth-century literature, and the history of science and technology.
Laura Otis is Associate Professor of English, Hofstra University. In 2000, she was awarded a MacArthur Foundation Fellowship for her interdisciplinary studies of literature and science. Her previous books include Membranes: Metaphors of Invasion in Nineteenth-Century Literature, Science, and Politics and Organic Memory: History and the Body in the Late Nineteenth and Early Twentieth Centuries.
Recent debates surrounding human security have focused on the satisfaction of human needs as the vital goal for global development. Peter Wilkin highlights the limitations of this view and argues that unless we incorporate an account of human autonomy into human security then the concept is flawed. He reveals how human security is a concern with social relations that connect people in local, national and global networks of power, structured through capitalism and hierarchical inter-state systems. Autonomy, as an aspect of human security, depends upon the ability of citizens to gain information about the processes that shape their lives. In this respect autonomy and communication are inherently linked and are prerequisites for the establishment of meaningful democratic systems.
To what extent do developments in global communication enhance or undermine autonomy? As the world's media companies continue to merge, we are moving towards an ever more commercially driven system of global information. Wilkin argues that private ownership provides an increasingly powerful obstacle to human autonomy, and that the neo-liberal institutional and policy framework – now a global tendency – raises major problems for the attainment of human security. At the same time it has provided the ideological justification for the extension of private power into ever wider areas of public life. Changes in global communication reflect wider tendencies to enhance the power of global elites at the expense of working people and the author illustrates how and why these changes have taken place and the forms of opposition that have arisen in response to them.
Of the many groundbreaking developments in the 2008 presidential election, the most important may well be the use of the Internet. In Politicking Online contributors explorethe impact of technology for electioneering purposes, from running campaigns andincreasing representation to ultimately strengthening democracy. The book reveals how social networking sites such as MySpace and Facebook are used in campaigns along withe-mail, SMS text messaging, and mobile phones to help inform, target, mobilize, and communicate with voters.
While the Internet may have transformed the landscape of modern political campaigns throughout the world, Costas Panagopoulos reminds readers that officials and campaign workers need to adapt to changing circumstances, know the limits of their methods, and combine new technologies with more traditional techniques to achieve an overall balance.
Practical Communication Theory
Dave Adamy The Institution of Engineering and Technology, 2014 Library of Congress TK5105.A35 2014 | Dewey Decimal 621.384
Practical Communication Theory, 2nd Edition enables the reader to quickly and easily generate the answers to real-world problems encountered in specifying, testing, and fielding any type of systems that involve radio propagation. It deals with free space radio propagation and propagation near the ground and over the ridge lines. As a bonus, this book also includes a special antenna and propagation slide rule, with unique scales, along with detailed explanations, and examples, of how to use it.
In Pump and Dump: The Rancid Rules of the New Economy,Robert H. Tillman and Michael L. Indergaard argue that these scandals are symptoms of a corporate governance problem that began in the 1990s as New Economy pundits claimed that advances in technology and forms of business organization were changing the rules. A decade later, it looked more like a case of no rules. Endless revelations of fraud in the wake of corporate bankruptcies left ordinary investors bewildered and employees out of work with little or nothing.
Tillman and Indergaard observe that victims were taken in by organized behavior that calls to mind “pump and dump” schemes where shadowy swindlers push penny stocks. Yet, in the 1990s it was high-profile firms and high-status accomplices (financial analysts, bankers, and accountants) who used powerful institutional levers to pump the value of stock—duping investors while insiders sold their holdings for fantastic profits before the crash.
The authors explain how it was that so much of corporate America came to resemble a two-bit securities scam by focusing on the rules that mattered in three critical industries—energy trading, telecommunications, and dot-coms. Free-market hype and policies at the national level set the tone. While Wall Street wrapped itself in star-spangled packaging and celebrated its purported “democratization,” in the real halls of democracy congressional allies of business gutted protections for ordinary investors. In the regulatory vacuum that resulted, business professionals who were supposed to watch corporations instead promoted New Economy doctrines and worked with executives to tout their firms as New Economy contenders. Ringleaders in the inner circles that committed fraud made their own rules, which they enforced through a mix of bribery and bullying.
At a time when there is growing debate about proposals to privatize programs like Social Security and to promote an “ownership society,” Pump and Dump offers a path-breaking analysis of America’s most urgent economic problem: a system that relies on self-regulation and the rancid politics that continue to support the short-term interests of financial elites over the long-term interests of most Americans.
Thanks to inexpensive computers and data communications, the speed and volume of human communication are exponentially greater than they were even a quarter-century ago. Not since the advent of the telephone and telegraph in the nineteenth century has information technology changed daily life so radically. We are in the midst of what Gerald Brock calls a second information revolution.
Brock traces the complex history of this revolution, from its roots in World War II through the bursting bubble of the Internet economy. As he explains, the revolution sprang from an interdependent series of technological advances, entrepreneurial innovations, and changes to public policy. Innovations in radar, computers, and electronic components for defense projects translated into rapid expansion in the private sector, but some opportunities were blocked by regulatory policies. The contentious political effort to accommodate new technology while protecting beneficiaries of the earlier regulated monopoly eventually resulted in a regulatory structure that facilitated the explosive growth in data communications. Brock synthesizes these complex factors into a readable economic history of the wholesale transformation of the way we exchange and process information.

Reviews of this book: The Second Information Revolution is important reading for anyone who needs to understand the functioning of American telecommunications, either to be able to analyse today's financial markets or to understand or influence public policy in this area. --Wendy M. Grossman, Times Higher Education Supplement [UK]
Reviews of this book: Brock traces a phenomenon he refers to as the 'second information revolution.' According to Brock, there have been two times in history when information technology has dramatically changed daily life. The first 'information revolution' occurred with the advent of the telephone and telegraph, which made communication less expensive and more readily available. The second information revolution is currently in progress...A concise, thorough, and well-written history of the transformation in exchanging and processing of information. --K. A. Coombs, Choice
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.
Tracing the development of communication markets and the regulation of international communications from the 1840s through World War I, Jill Hills examines the political, technological, and economic forces at work during the formative century of global communication.
Hills analyzes power relations within the arena of global communications from the inception of the telegraph through the successive technologies of submarine telegraph cables, ship-to-shore wireless, broadcast radio, shortwave wireless, the telephone, and movies with sound. As she shows, global communication began to overtake transportation as an economic, political, and social force after the inception of the telegraph, which shifted communications from national to international. From that point on, information was a commodity and ownership of the communications infrastructure became valuable as the means of distributing information. The struggle for control of that infrastructure occurred in part because British control of communications hindered the growing economic power of the United States.
Hills outlines the technological advancements and regulations that allowed the United States to challenge British hegemony and enter the global communications market. She demonstrates that control of global communication was part of a complex web of relations between and within the government and corporations of Britain and the United States. Detailing the interplay between American federal regulation and economic power, Hills shows how these forces shaped communications technologies and illuminates the contemporary systems of power in global communications.
Technologies of Freedom
Ithiel de Sola Pool Harvard University Press, 1983 Library of Congress KF2750.P66 1983 | Dewey Decimal 343.730998
How can we preserve free speech in an electronic age? In a masterly synthesis of history, law, and technology, Ithiel de Sola Pool analyzes the confrontation between the regulators of the new communications technology and the First Amendment.
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.
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.
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.
In recent years the tremendous growth of the service sector—including international trade in services—has outstripped that of manufacturing in many industrialized nations. As the importance of services has grown, economists have begun to focus on policy issues raised by them and have tried to understand what, if any, differences there are between production and delivery of goods and services.
This volume is the first book-length attempt to analyze trade in services in the Asia-Pacific region. Contributors provide overviews of basic issues involved in studying the service sector; investigate the impact of increasing trade in services on the economies of Taiwan, Korea, and Hong Kong; present detailed analyses of specific service sectors (telecommunications, financial services, international tourism, and accounting); and extend our understanding of trade in services beyond the usual concept (measured in balance of payment statistics) to include indirect services and services undertaken abroad by subsidiaries and affiliates.
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 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.
