KT 5G Development Forum(KT 5G-DF) was organized by KT in May 2016 in order to promote early development of the devices and systems for the PyeongChang 5G trial service based on the KT 5G-SIG specification. Besides jointly developing 5G network devices and systems and testing compatibility between the devices developed by each manufacturer, it will also provide end-to-end platform for 5G service verification. Through KT 5G Development Forum, KT will provide its leadership in accelerating the 5G development and commit to providing the world’s first 5G trial service at the PyeongChang 2018 Olympic Winter Games.

KT will use 28GHz mmWave for 5G trial service at the PyeongChang 2018 Olympic Winter Games. However, using mmWave for the mobile communication was unprecedented. KT took the initiative to study, test, analyze and plan for the 5G trial system deployment. KT had completed the actual field measurements at Gangnam and PyeongChang areas for cell site planning and results were also contributed to 3GPP for channel modeling study. KT will continue the effort to further optimize the 5G deployment for the successful 5G Olympics.

On 2016 October 25th, KT and Samsung have managed to successfully test the world’s first connection on 5G network. The 5G connection was established through a network built on end to end 5G technologies. It includes all the necessary processes such as synchronization and authentication for 5G access communication. This demonstration is different from other tests conducted earlier. The earlier tests used prototypes base stations and proprietary specifications. KT and Samsung instead used a common specification as put forward by KT 5G-SIG.
