SK Telecom (SKM 0.70%) launched the world's first 4G LTE-Advanced network in South Korea today, providing the fastest available data speeds for the same price as 4G LTE. 

The company's LTE-A network brings download speeds of up to 150Mbps, which is two times faster than LTE speeds and 10 times faster than 3G speeds. The new network is currently available in Seoul and areas of Gyeongg-do and Chungcheong-do, with plans to expand coverage to 84 cities across South Korea.

Park In-sik, president of network business operations at SK Telecom, said in a press release, "SK Telecom is proud to announce the world's first commercialization of LTE-A. By supporting twice faster speeds than LTE, LTE-A will not only enhance customers' satisfaction in network quality, but also give birth to new mobile value added services that can bring innovative changes to our customers' lives."

Right now, the only LTE-A phone available is the Samsung Galaxy S4 LTE-A, but SK Telecom said in a statement that it will have seven LTE-A phones available in the second half of 2013.
