SK Telecom says it covers 53 cities in Korea with LTE-Advanced Pro coverage that utilizes five component-carrier carrier aggregation and four-by-four multiple-input-multiple-output antenna technology, and that it’s getting ready to launch gigabit-speed LTE-A Pro in the first half of 2018.
The 5CC carrier aggregation implementation supports speeds up to 700 Mbps, and SK Telecom said that it has just added six cities where users on the Samsung Galaxy S8 (with an over-the-air firmware upgrade) can achieve speeds of up to 900 Mbps LTE-A Pro through a combination of 4×4 MIMO and three-band/four-band CA. Those cities are Seoul, Busan, Daegu, Gwangju, Daejeon and Ulsan.
