This book showcases state-of-the-art research and innovations in communications technologies for connected smart cities. The interfaces of various communication technologies are explored, alongside design-specific issues for the integration of different architectural components, and the interoperability of various solutions.

Satellite communications plays a vital role in ensuring seamless access to any telecommunications service anytime and anywhere, and is only 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 complements terrestrial telecommunication solutions in various scenarios and will ensure the expansion of the 5G ecosystem towards highly reliable and secure global wireless networks.Satellite Communications in the 5G Era explores promising scenarios for 5G Satellite Communications (SatCom), novel paradigms for satellite-terrestrial integration and emerging technologies for the next generation of satellite systems and hybrid/integrated satellite-terrestrial systems, and focuses on recent research efforts towards 5G and beyond.Topics covered include the role of SatComs in the 5G ecosystem; satellite use cases and scenarios for 5G enhanced Mobile Broadband (eMBB); Software Defined Networking (SDN)-enabled SatCom networks for satellite-terrestrial integration; Network Function Virtualization (NFV)-based scenarios for satellite-terrestrial integration; propagation and system dimensions in extremely high frequency broadband aeronautical SatCom systems; link characterization and system perspective of the next generation non-geostationary SatCom systems; diversity combining and handover techniques in Medium Earth Orbit (MEO) satellites; powerful nonlinear countermeasures for multicarrier satellites; Software Defined Radio (SDR)-based multibeam satellite precoding demonstrator; beam-hopping systems for the next generation SatCom systems; optical on-off keying data links for low earth orbit downlink applications; ultra-high speed data relay systems; on-board processing for satellite-terrestrial integration; on-board interference detection and localization for SatComs; advanced random access schemes in SatComs; interference avoidance and mitigation techniques for hybrid satellite-terrestrial networks; dynamic spectrum sharing in hybrid satellite-terrestrial systems; and two-way satellite relaying.
