KT Builds 5G Standalone Mode Network

[Asia Economy Reporter Koo Chae-eun] KT announced on the 25th that it has built a 5G Standalone (SA) network on the commercial network in the Paju Industrial Complex, Gyeonggi-do.

To provide 5G SA services to customers, KT has been conducting equipment interworking and functional tests in both testbed and commercial network environments since early this year. Recently, KT established the SA network in the Paju Industrial Complex and focused on verifying B2C services in the commercial network environment to secure service quality at a commercial level.

Stable voice calls and data communication functions are essential to provide 5G SA services to customers. In the early stages of SA service, it is expected that voice calls will be provided using system fallback technology. This technology offers voice services based on smooth signal processing between 5G and LTE. KT has succeeded in securing quality that provides stable 5G SA data communication without interruption in mobile environments. Through SA testing in the commercial environment, KT has succeeded in securing voice call services and data communication stability, while also laying the foundation to provide network slicing functions that support customized quality according to the service.

Lee Cheol-gyu, Vice President and Head of KT’s Network Division, said, “5G SA is expected to be an important opportunity for industrial innovation in Korea as a true 5G network,” and added, “KT will continue to develop differentiated technologies and stabilize services until the launch of 5G SA services to provide ‘customer-centric 5G services’ that meet customers’ needs.”
