South Korea launches the world’s first fully-fledged 5G mobile networks Friday, a transformation leap that already has superpowers sparring for control of an innovation that could potentially change the day-to-day lives of billions of people.
The superfast communications which operates by fifth-generation wireless technology will ultimately underpin everything from toasters to telephones; from electric cars to power grids.

It is crucial for the future development of devices ranging from self-driving vehicles that send data traffic to one another in real time, industrial robots, drones and other elements of the Internet of Things. 5G’s hyper speed can connect one million devices within a one square kilometre zone simultaneously.
