One of the crucial challenges for future smart cities is to devise a citywide network infrastructure capable of effectively guaranteeing resource-efficient and reliable communications while managing the complexity of heterogeneous devices and access technologies. This edited book highlights and showcases state of the art research and innovations in 5G and beyond wireless communications technologies for connected smart cities. The main objectives of this work include the exploration of recent advances and application potentials of various communication technologies as promising enablers for future networked smart cities, the investigation of design-specific issues for the integration of different architectural components of smart cities, and addressing various challenges and identifying opportunities in terms of interoperability of potential solutions.

Power Line Communication (PLC) is a well-established technology that allows the transmission of data through electrical wires. A key advantage of PLC is its low cost of deployment when the electrical wiring infrastructure already exists, enabling it to compete or work in conjunction with wireless technologies. PLC has recently received growing attention and significant investments within the development of the Smart Grid (SG), that in turn requires sophisticated data exchange and communication.
