Published2017.02.10 19:27SK Telecom announced on the 9th that it has completed the construction of a next-generation railway communication standard 'Integrated Railway Wireless Network (LTE-R)' on Busan Metro Line 1 together with Busan Transportation Corporation.
Following the contract signing for the 'LTE-R Construction Project' with Busan Transportation Corporation in August 2015, SK Telecom has converted the existing analog voice communication network to a data environment-based LTE-R network across a 40.48 km section covering 40 stations on Busan Metro Line 1.
After approximately two months of trial operation and preparation phases, LTE-R is scheduled to commence full-scale operation around April.
In existing railway radio communications, only voice calls and radio transmission between personnel were possible, but through the LTE-R network, control centers, train operators, station staff, and rescue personnel can simultaneously exchange information in various ways including real-time video transmission, group calls, and text messaging.
