KT Corporation WiBro Network, Seoul, South Korea

KT Corporation is one of Korea’s leading telecommunications companies, which provides services to residential and business users across South Korea.

The company offers fixed-line telephone services, business and data communication services including broadband internet access and leased-line, mobile services through KT, one of its subsidiaries (previously KT Free tel), which is the second largest mobile provider.

Other telecommunications services provided include system and network integration, as well as satellite communications. The corporation owns two satellites, all of South Korea’s domestic public exchanges, the complete network of local telephone lines, public long-distance telephone transmission facilities and the primary data communications network in the country.

The latest innovation the company has introduced is mobile WiMAX coverage; the company started a trial of the technology across Seoul in the first quarter of 2006.

WiBro got off the ground at some high-demand areas in Seoul and the city’s outskirts, including Sinchon, Gangnam-gu, Seocho-gu, Songpa-gu, Bundang and along the Bundang subway line.

Although the trial service has attracted few users (less than 1,000 due to lack of access devices) in April 2007 they decided to expand the network to cover the whole of the city.
