KT Corporation (formerly Korea Telecom) has officially launched its 5G network commercial service through an artificial intelligence-equipped robot named Lota, which will guide visitors through the Seoul Sky Observatory on top of the 123-story Lotte World Tower in eastern Seoul. The company plans to expand into new businesses with more pilot clients, using intelligent machines and business-to-business (B2B) operators.
KT deployed the first phase of its 5G network in late November in the greater Seoul metropolitan area, in the country’s most populated, major metropolitan cities outside Seoul as well as in more isolated areas.
KT plans to expand its nationwide 5G network to 24 major cities, key transport routes such as expressways, subways, high-speed railways, large universities and neighborhood shopping areas. The next phase of the new network will provide seamless 5G mobile coverage.
KT’s 5G service owes its ultra-low latency to an Internet backbone with full mesh topology and edge communication centers based on control and user plane separation (CUPS) technology.
“Full mesh topology is an up-to-date technology in which every node in the network has a circuit connection to every other node. CUPS is an advanced architecture enhancement technology indispensable for standalone (SA)-based networks of 3rd Generation Partnership Project (3GPP) standards,” Oh Sung-Mok, head of the Network Group, said.
The first customer service available on KT’s 5G network is 10 gigabytes of data for a mobile hotspot terminal. A smartphone with a mobile hotspot function provides an Internet connection for other mobile devices, such as notebook computers.
“KT has ushered in the 5G era by launching commercial 5G service on our 5G network across the country, and we will do our best to extend our coverage to every nook and cranny of the most remote mountain areas and islands, as well as urban cores,” KT’s Oh said. “We will provide the best quality 5G service to our clients by continuing to develop cutting-edge technologies.”
