South Korea’s LG U + officially launched its LTE-Advanced service, promising download speeds of 75 Mbps to 150 Mbps — roughly twice the performance of its standard LTE service.
The LTE-A network is using carrier aggregation of 800 MHz and 2.1 GHz spectrum. Compatible handset initially include a version of the Samsung Galaxy S4 and soon the LG Electornics Optimus G2. By the end of the year, the company expects there will be six LTE-A terminal devices on the market.
- LG U+ said its network will offer pure LTE connectivity between compatible handsets, where voice is carried by VoLTE rather than falling back to CDMA.
- LTE-A is initially available in Seoul / Manila / Gwangju, Daejeon and other major cities.
- LG U+ vendors include LG, Ericsson, Nokia Siemens Networks and Samsung.

- In late June 2013, SK Telecom launched the world’s first LTE-Advanced (LTE-A) service through smartphones. The LTE-A service offers download speeds of up to 150 Mbps, which is two times faster than its regular LTE service, and 10 times faster than its 3G network. LTE-A coverage initially is available in Seoul and central city areas of Gyeongg-do and Chungcheong-do. Expansion to 84 cities nationwide is planned. At top speed, LTE-A users can download an 800MB movie in just 43 seconds. The LTE-A implementation leverages several advanced mobile network technologies including Carrier Aggregation (CA) and Coordinated Multi Point (CoMP). SK Telecom plans to implement Enhanced Inter-Cell Interference Coordination (eICIC) in 2014.
