It’s predicted that 5G, the fifth generation of mobile network, would be commercially available worldwide shortly as 5G currently deployed has limited coverage. There will be a substantial boost in performance and reliability compared to the current generation - 4G mobile network. The packet latency of 5G is roughly ten-fold less than that of existing 4G networks. For several applications of 5G, packet latency must be at about one millisecond. For emerging new services such as virtual reality (VR), live streaming using mobile networks, autonomous vehicles, and tactile Internet with the capability of machines and equipment remote operation and high sensitivity via mobile network, significantly low latency is required.
