Ericsson says that KT is in the final stages of testing its new 5G trial network in the city of PyeongChang, host of the 2018 Winter Games.
Following an MoU that was signed in 2015, KT, Ericsson, and several other technology partners are cooperating to build, test and optimize a 5G network in preparation for Winter Games. At an April 2017 meeting, KT and its partners agreed on steps to deploy and optimize a trial 5G network during 2017 including plans for joint technology development.
Also, Ericsson and KT conducted tests along the Incheon Airport Railway – a new high speed rail line linking the capital of Seoul with Incheon International Airport. The tests – which included handover between 5G base stations along the railway – achieved a peak throughput of 4 Gbps.
Moving forward, Ericsson and KT have agreed to jointly develop beam forming/beam tracking technology and 5G-LTE inter-working technology to optimize capacity and coverage with robust performance.
Infrastructure for the 28-GHz trial 5G trial network will include virtual RAN (vRAN) and virtualized core. Ericsson said KT is already in the process of conducting interoperability tests based on the PyeongChang 5G SIG specification.
“Stability and interoperability among multiple services, systems and device manufacturers needs to be verified well in in advance of the trial network,” said Seong-Mok Oh, head of Network Group at KT. “We are raising the bar through our collaboration with partners such as Ericsson.”
