The South Korean telecom giant SK Telecom Corp Ltd ( SKM - Analyst Report ) has joined hands with telecom carriers for the commercial deployment of Long Term Evolution (LTE) services, also known as 4G networks. Given the surge in data traffic demand, the company will launch its LTE services in Seoul.

SK Telecom has selected Samsung Electronics, LG-Ericsson and Nokia Siemens Networks as the key equipment suppliers for its 4G LTE network. The LTE network allows up to 75 Mbps downlink and 37.5 Mbps uplink speed, which are five and seven times faster than those of WCDMA networks, respectively.

The demand for high-speed data services is growing rapidly, leading to a growing requirement for wireless data services. Following the LTE launch in the South Korean capital, SK Telecom expects to add 0.3 million LTE subscribers from its domestic market in 2011. This number is expected to reach 6 million and 10 million by 2013 and 2015, respectively.
