KT is preparing to launch LTE-A service this month using carrier aggregation technology to achieve downlink speeds of up to 150 Mbps. The Korean operator secured the 1.8 GHz frequency band at auction last week. The license covers 20 MHz in the band.
The company has about 100,000 base stations ready for upgrade.
KT also claims its LTE-A will be more energy efficient at the handset, enabling longer battery life for end users.
SK Telecom plans to deploy 32,000 LTE-Advanced base stations by the end of the year, which will cover 84 cities nationwide and approximately 300 college campuses.
Ericsson confirmed its major role in the SK Tel 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.
