The Korean telecom operator developed the tri-band LTE-A CA technology in January 2014 and demonstrated the 450Mbps tri-band LTE-A by binding three 20MHz bands at the Mobile World Congress 2014 in February 2014.
The company has already secured Wideband LTE-A coverage in main areas of 84 cities and can offer tri-band LTE-A service by adding 2.1GHz base stations. SK Telecom plans to build more than 26,000 2.1GHz base stations during the first quarter of 2015 in Seoul/ Seoul Metropolitan Area, central areas of all cities as well as all subway lines in Korea.
SK Telecom customers can use Galaxy Note 4 S-LTE, the first tri-band LTE-A capable device, to access tri-band LTE-A in Korea.
