Core Network Equipment Linked with Base Station and Terminal Wireless Connection
Ultra-Low Latency Service Available for Preview at KT Booth 5G Zone

KT announced on the 28th that it unveiled a '5G Network Environment (5G End-to-End Network)' based on PyeongChang 5G specifications at MWC 2017.

This is the first time a complete 5G network has been demonstrated by integrating 5G terminals, base stations, and core equipment.

The '5G Network Environment' (5G End-to-End Network) jointly developed by KT and Samsung Electronics not only wirelessly connects base stations and terminals, but also links core network equipment that serves as a control tower. It was reported to perform all core functions necessary to provide 5G services to customers, including authentication, mobility, and interoperability with external networks.

Additionally, KT applied '5G Distributed Architecture' technology to the '5G Network Environment', which efficiently improves the existing 4G (LTE) network structure that previously required centralized data traffic processing at a central network center.

By utilizing '5G Distributed Architecture' technology, the core network that processes data traffic can be virtualized and easily distributed to any desired location. Data transmission and reception begins from the location closest to the customer, enabling smooth transmission of large-scale media that is difficult to handle in 4G (LTE) networks with ultra-low latency.

The '5G Network Environment' can be seen at the 5G Zone in the KT booth located in the 'Innovation City', the joint themed pavilion of the Global System for Mobile Communications Association (GSMA). Visitors can preview the 'ultra-low latency 5G service' where, when wearing wearable devices such as gloves equipped with motion sensors and moving, real-time images are transmitted to the studio as large-scale holograms through the '5G Network Environment'.

Jeon Hong-beom, Executive Director of KT Infrastructure Research Institute, stated, "Based on the 5G network environment including core equipment revealed this time, we plan to provide new experiential 5G services such as Sync View and Omni-view to visitors at PyeongChang in 2018," and added, "We plan to complete an intelligent 5G network based on the know-how of the world's first 5G trial service."
