It'll enable functions such as accommodating more internet of things devices and streaming HD videos on mobile networks.  > KT said 5G will be available to users in 85 cities in Korea by the end of the month. US carriers are also scrambling to roll out the technology. Verizon launched a limited 5G home broadband service last year, and the company plans to roll out mobile 5G service in 30 cities this year. AT&T's 5G network went live in select cities in December, though customers can only access it using Wi-Fi hotspots. The company also plans to launch mobile 5G in 2019.
