5G is the fifth generation of cellular mobile communications. It succeeds the 1G (voice only) , 2G (texting) and 3G (smartphones), and 4G ( connected systems, video etc). 5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. The first phase of 5G specifications in Release-15 will be completed by March 2019 to accommodate the early commercial deployment.

Verizons Ultra-Wide Band 5G network will allow up to 100 times better throughput, 10 times longer battery life and 1,000 times larger data volumes, all while increasing reliability 10 times over 4G.Latency will also be dramatically lowered. On 4G, latency was cut in half from 3G, with response times of 15 and 60 milliseconds, versus 120 milliseconds on 3G. On 5G Verizon is targeting that latency could drop to 1 millisecond or less, which woul make lag times impossible to detect. 

With its combination of greater data transfer speeds and heightened processing power, 5G will enable even more technology to connect, leading the Internet of Things to be deployed on a truly massive scale. Todays estimates of 8 billion IoT devices could climb as high as 20-25 billion devices by 2020 according to Gartner Research. 

The massive improvements in 5G cellular technology will help usher in the deployment of Edge Computer.
