The technology development and standardization of 5G radio access have been rapidly progressing. A major agreement was reached in the past few weeks, enabling industry to complete its product development, with early commercial network deployments expected in 2018. In addition to enhancing mobile broadband services, which have dominated 4G, 5G aims to enable critical machine type communications (cMTC) and support Internet of Things (IoT) using the same network. This ambition poses stringent design requirements and performance objectives in many different dimensions. For example, in addition to significant improvements in peak data rates and network capacity compared to existing cellular technologies, 5G performance objectives further include ultra-low latency and ultra-reliability for cMTC, and superior device energy efficiency, low device cost, ubiquitous coverage reaching devices deep indoors, and ultra-high device connection density for IoT. The three pillars of 5G technologies, enhanced MBB, cMTC, and IoT, extend 5G services vastly to many new use cases. In this talk, we first describe the principles adopted in 5G to achieve its performance objectives. We give an overview of upcoming early deployments, which address MBB primarily. We also give examples of how 5G enables smart city and connected industry. Finally, we discuss the next steps in 5G and what may come beyond 5G.
