5G Essentials

Learn the design motivation and underlying technology of 5G service.

GK# 100414

Course Overview


5G is the next generation of mobile networks beyond today's 4G LTE mobile network. The vision of 5G is becoming clearer, and most experts predict 5G will feature blazingly fast network speeds at 20 Gbps or higher with latency at mere milliseconds. The entire 5G approach takes advantage of containers, virtualization, SDN, and NFV. This course will help you understand how 5G accomplishes these goals by observing how it works.
