South Korea has launched the world’s first nationwide 5G mobile networks. South Korean telecom operators SK Telecom, KT, and LG Uplus began their services on 4^th April, despite previously announcing the launch date would be April 5.
5G (5^th Generation) is a version of mobile communications. It succeeds LTE mobile networks- 4G, 3G, and 2G (GSM). In telecommunication, Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals.
According to experts, 5G would provide near-instantaneous connectivity —20 times faster than 4G. The other expected benefits of 5G include reduced latency (faster response time), energy saving, cost reduction, higher system capacity, and mass device connectivity.
