5G test networks to be built in key areas of Pyeongchang, Gangneung, and Seoul.
Testing previously impossible environments with a 'mobile 5G system'

KT announced that it has successfully conducted 5G field tests in major areas of Pyeongchang, Gangneung, and Seoul, following Gwanghwamun, in order to successfully present 5G pilot services at the 2018 Pyeongchang Winter Olympics.

Last December, KT built a '5G test network' in the Gwanghwamun Square area of Seoul and successfully conducted a 'handover' to minimize mobile communication interruptions by using buses equipped with 5G terminals in urban areas for the first time in Korea.

KT explained that for this test, it expanded to major areas in Seoul, including the 'PyeongChang Mountain Cluster' and 'Gangneung Coastal Cluster' where the 2018 PyeongChang Winter Olympics will be held, and Gangnam Station with a large floating population, and built a '5G test network' based on the 'PyeongChang 5G standard'.

KT announced that it successfully implemented essential 5G technologies such as massive antenna and wireless beam forming and transmitted data normally in an Olympic stadium with many radio wave obstacles and an environment with explosive LTE data usage by utilizing the '5G test network'.

In particular, KT was able to quickly build a '5G test network' by utilizing a 'mobile 5G system' that links 5G base stations and antennas with mobile base stations in this test, allowing testing in environments that were previously impossible.

Based on the results of this field test, KT plans to develop 5G equipment optimized for commercial use in the second half of the year.

Seo Chang-seok, executive director of KT’s network strategy division, said, “KT is accelerating the construction of a 5G pilot network in the PyeongChang Winter Olympics venue area and major areas of Seoul,” and added, “We will provide the highest level of 5G wireless quality through sufficient field tests within 2017.”
