"This comprehensive guide contains cutting-edge information from telecommunications experts working at the forefront of 5G innovation. You will learn about the foundations of 5G technology-not just the new standards, but the reasons and stories behind them. The book shows how to get the most out of 5G, including high data rates, ultra-reliability, ultra-low latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. Fundamentals of 5G Communications offers comprehensive coverage of all major vertical domains and applications, with a focus on practical, commercial implications. You will get complete explanations of commercial applications, including eXtended Reality (XR) applications, factory automation, remote/autonomous driving and platooning, sensor sharing, and more. The book serves both as an essential reference for telecom professionals and as a textbook for students learning about 5G."

"Evolving across the previous four generations, wireless cellular technology has transformed the way in which people communicate and acquire information. This transformation has taken place gradually from the 90s to the first decade of the twenty-first century, with the first and second generation of cellular systems sup- porting mobile voice transmission, and the third and fourth generation enabling mobile Internet access. With its fourth generation (4G), wireless cellular technology has arguably completed an arc that was started by the work of Claude Shannon at the Bell Labs in the 40s. In his seminal 1948 paper, Shannon derived a theoretical upper bound on the amount of information that can be conveyed on a communication link between two end points. His proof was famously non-constructive, and hence it left open the problem of engineering efficient systems for the encoding and decoding of information at transmitter and receiver, respectively. The problem was essentially solved by the discovery of turbo and Low-Density Parity Check (LDPC) codes and corresponding decoders, all of which are included in the 4G standard. As suggested by the discussion above, the path followed by the first four gener- ations of cellular technology was one inspired by the goal of reaching the Shannon limit for communication over point-to-point links. In the process, communica- tion engineers strived, and eventually succeeded, to design practical solutions that matched the theoretical results developed by Shannon. In contrast, the next generations of wireless systems, starting with the fifth (5G), face a new de- sign landscape that lacks the strong theoretical guiding principles of Shannon's analysis of point-to-point communications" [Publisher]

Toutes les cinq secondes en moyenne, votre portable se manifeste à vous. Cet ouvrage se penche sur ce phénomène de société et montre comment cette sollicitation permanente se transforme en dispositif de mobilisation. Qui dit mobilisation dit militarisation. Ainsi le mobile nous transforme en militaires, abolissant la distinction entre public et privée, entre jour et nuit, entre travail et repos, en nous mobilisant en permanence : nous voilà sommés d'être sans cesse responsables, de ne rien oublier ni pardonner.Le portable aurait-il contribué à l'émergence d'un nouvel état de guerre ?
