5G Networks : Background, Issues and Security

Since the first mobile phones were made available in the 1980s, telecommunication providers have been investing in mobile networks to expand coverage, improve services, and attract more users. First-generation networks supported mobile voice calls but were limited in coverage and capacity. To address those limitations, providers developed and deployed second-generation (2G) mobile networks, then third-generation (3G), and fourth-generation (4G) networks. Each generation offered improved speeds, greater capacity, and new features and services. In 2018, telecommunication providers began deploying fifth-generation (5G) networks to meet growing demands for data from consumer and industrial users. 5G networks are expected to enable providers to expand consumer services (eg: video streaming, virtual reality applications), support the growing number of connected devices (eg: medical devices, smart homes, Internet of Things), support new industrial uses (eg: industrial sensors, industrial monitoring systems), perform advanced data analytics, and enable the use of advanced technologies (eg: smart city applications, autonomous vehicles). This book provides a background on mobile technologies, and addresses the race to 5G, factors affecting 5G deployment, and national security.
