5G, or fifth-generation mobile communication technology, is the latest generation of cellular mobile technology and an extension of the 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems, which for the first time realizes the unification of global standards.
       The performance of 5G is characterized by ultra-high speed, ultra-low latency, ultra-low energy consumption, and ultra-multiple (large-scale device) connectivity. With the help of 5G technology, the technology of drones, unmanned aerial vehicles, smart homes, VR/AR, industrial Internet, smart cities, and other industries that have changed the way human beings live and work will be developed at a high speed.
