Introduction

The new 5G technology is not just the next version of mobile communications, evolving from 1G to 2G, 3G, 4G, but it provides a new approach giving ubiquitous connectivity.

5G technology is very different. Previous systems had evolved driven more by what could be done with the latest technology. The new 5G technology has been driven by specific uses ad applications.

5G mobile communications has been driven by the need to provide ubiquitous connectivity for applications as diverse as automotive communications, remote control with haptic style feedback, huge video downloads, as well as the very low data rate applications like remote sensors and what is being termed the IoT, Internet of Things.

5G standardisation

Like all widely used systems, the 5G mobile communications is governed by a series of standards. Building on 2G GSM, 3G UMTS and then 4G LTE, the 5G standard come under the auspices of 3GPP - Third generation Partnership Project.

3GPP has a number of different work groups, each addressing different elements of the required standards. They draw on industry expert who give of their time and are sponsored by relevant mobile communications companies. In this way the standards are written and developed.
