Company History

KT was the first and is the largest telecom company in Korea. The company’s operation initially started in 1885, then known as Hanseong Telegraph Office. In 1980’s, KT introduced fixed line telephones to households as a leader in the communication market, and in 1990’s, it became a leader both in wired and wireless communication markets by introducing as many as 20 million lines in fixed telephones and mobile phone with PCS as well as high-speed internet ADSL, paving a way for KT to become a representative communication service provider in Korea. After its complete privatization in 2002, KT has led the informatization era by introducing high speed internet and 3G mobile communication service for the first time within the country.

In 2019 KT Sat successfully conducted the world’s first 5G data transmission with a satellite connection. The test was carried out using Koreasat-6, positioned at 116° E, and was done in collaboration with the KT Institute of Convergence Technology.

KT SAT plans to launch Koreasat-6A (Mugunghwa-6A) satellite in 2025 to succeed Koreasat-6, which will be decommissioned after 15 years of service. The satellite will provide high-speed data transmission over 10 times faster than that of the classic fixed-satellite service (FSS). Construction will start in 2021 and the launch will be conducted by Arianespace launch operator.
