South Korea to launch world’s first national 5G mobile networks

South Korea launches the world’s first fully-fledged 5G mobile networks Friday, a transformational 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 heralded by fifth-generation wireless technology will ultimately underpin everything from toasters to telephones; from electric cars to power grids. But while the South has won the race to be first to provide the user experience, that is only one part of a wider battle that has pit the United States against China and ensnared giants including Huawei.

Hyper-wired South Korea has long had a reputation for technical prowess, and Seoul has made the 5G rollout a priority as it seeks to stimulate stuttering economic growth. The system will bring smartphones near-instantaneous connectivity — 20 times faster than the existing 4G — allowing users to download entire movies in less than a second.
