LG Uplus announced on the 8th that it will launch an open innovation project to lead the evolution of LTE-R technology together with small and medium-sized enterprises at its 'LTE-R Comprehensive Verification Center.'

LTE-R (LTE-R) is a technology that utilizes LTE, a 4G mobile communications technology, for railways. It aims to improve aging train radio equipment (VHF) and efficiently transmit necessary voice, video, and data between running trains, between trains and control centers, and between maintenance personnel.

Through this project, LG U+ will explore ways to integrate new technologies and solutions with small and medium-sized enterprises (SMEs) to support LTE-R deployment on existing and new railway lines. The goal is to strengthen collaboration with SMEs and startups seeking to enter the LTE-R field and enhance the competitiveness of the LTE-R Comprehensive Verification Center.

The LTE-R Comprehensive Verification Center is an LTE-R test center built earlier this year through a long-distance transmission network between the LG Science Park in Magok, Seoul (center facilities) and the Daejeon R&D Center (field facilities). It is the only platform in Korea with a structure 100% identical to the actual railway operating environment, providing an optimal environment for various partners to extract various test and verification data.

The Integrated Verification Center also boasts a backpack-type mobile base station equipped with center equipment, enabling it to measure radio environment and conduct call testing tailored to each regional railway operation site. Furthermore, facilities for testing eMBMS (eMBMS) technology have been established, enabling stable group call service testing and verification in response to peak call volumes.

LG U+ also offers comprehensive training programs for LTE-R. The state-of-the-art training facility at its Daejeon R&D Center allows for a combination of theory and practice. In addition to basic 700MHz wireless network technology for communication between the LTE-R Center and field sites, the company has developed and operates specialized LTE training programs covering transmission, networking, and power generation. Through these programs, LG U+ plans to support the development of specialized personnel and technological advancements for its partners and customers.

Oh Young-hyun, head of LG Uplus' wireless business division, said, "As the LTE-R construction project has recently been in full swing, we have established an open testing environment based on collaboration with small and medium-sized enterprises." He emphasized, "Through this project, we will lay the foundation for improving the stability and quality of products to be supplied to the railway integrated wireless network site, and furthermore, we will strive to lead the market so that the entire domestic LTE-R technology can be upgraded to the next level."

Meanwhile, LG U+ has been upgrading the aging train wireless system of subway lines 2 and 5 with LTE-R in cooperation with Seoul Metro since June 2018. Last month, we won the contract for the Sillim Line light rail LTE-R project, and are currently building an integrated railway wireless network in the Wonju-Jecheon section of the Jungang Line, including the Osong Test Line of the Korea Railroad Facilities Corporation.
