Ericsson supports expansion of SK Telecom’s LTE-Advanced service in South Korea

Ericsson has supported SK Telecom, South Korea’s leading telecommunications operator, in expanding its LTE-Advanced commercial service network, via its local entity Ericsson-LG, to downtown areas of 84 cities nationwide, including the entire Seoul metropolitan area and six other major cities.

SK Telecom commercialised its LTE-Advanced service with up to 150Mbps mobile broadband speeds, twice that of LTE, for the first time in the world on 26 June 2013. At that time, the service included the entire Seoul area, the downtowns of 42 cities in Gyeonggi-do and Chungcheong-do provinces, and 103 campus towns.

With a plan to deploy 32,000 LTE-Advanced base stations by the end of the year, SK Telecom announced that it will expand LTE-Advanced service areas to 84 cities nationwide and start its LTE-Advanced service on approximately 300 college campuses.

Jan Signell, head of region North East Asia, Ericsson, said: "SK Telecom will be able to offer its users broader network coverage and an enhanced mobile broadband experience, ensuring continued loyalty among its customers and market leadership. Ericsson will keep collaborating with SK Telecom to exceed increasing user expectations in South Korea."

Ericsson was responsible for the upgrade, providing the software for carrier aggregation and multi-carrier technology for the B5 (850MHz) and B3 (1.8GHz) bands in South Korea’s southeastern regions, where Ericsson partnered with SK Telecom for the LTE network deployment and commercial service launch in 2011.

Through this LTE-Advanced commercial service expansion, SK Telecom can continue to differentiate itself on service quality, enabling high-speed mobile broadband services, such as HD video and better voice quality to a broader geographical area.

SK Telecom and Ericsson signed a memorandum of understanding (MoU) on R&D collaboration in February at the Mobile World Congress 2013, to cooperate in the development and demonstration of LTE-Advanced technologies. With this MoU, Ericsson has strengthened its technological cooperation in cutting-edge LTE-Advanced technologies, including small cell-related technologies, to accommodate surging data traffic with SK Telecom.
