Utilizing '5G-LTE interoperability technology' based on NSA, the international 5G standard
We will contribute to the creation of a global 5G ecosystem through technological cooperation.


KT announced that it has successfully demonstrated data roaming between the Pyeongchang 5G pilot network and Japan's NTT Docomo's commercial LTE (4G) network.

KT's '5G-LTE interoperability technology' used in the demonstration is based on '5G NSA (Non-Standalone, 5G-4G compatible standard),' a standard defined by 3GPP, and is a method scheduled to be adopted for the early commercialization of 5G. Following the establishment of the '5G NSA' international standard last December, rapid 5G commercialization is expected through the utilization of this standard.

This achievement follows the resolution for 5G cooperation among participants at the SCFA (Strategic Cooperation Framework Agreement) General Assembly, and preparations for 5G-LTE roaming between the two companies have been underway since last October. By concluding the demonstration, KT plans to continue global technology cooperation through SCFA to discover differentiated 5G technologies and services.



Meanwhile, KT completed the construction of 5G in Pyeongchang last October and finished preparing for 5G pilot services, and is accelerating preparations for commercialization through the development and verification of 5G technologies such as this 5G-LTE roaming.

"KT INS Division Head Executive Vice President Kim Young-sik said, 'KT is continuously striving to build a global 5G ecosystem through SCFA technology cooperation.' He added, 'Based on the know-how from the PyeongChang 5G service, we will continue to provide differentiated satisfaction to customers with the best 5G technology and lead the technology.'"
