LTE-R technology for railway control, soon to be commercialized? U+ completes verification
Published2019.11.16 12:01Immediately applicable to railway operation sites
LG Uplus announced on the 16th that it has completed verification of its new LTE-R technology solution.
LTE-R is a technology for utilizing LTE in railway business. It is used to improve the aging Very High Frequency (VHF) train radio equipment and transmit necessary voice, video, and data between running trains, between trains and the control center, and between maintenance personnel.
The LTE-R technology that U+ recently completed verification was conducted at the LTE-R Comprehensive Verification Center, which has conditions identical to the actual railway operation environment, so it can be immediately applied to railway operation sites.
An official from LG Uplus said, “We are currently reviewing ways to develop additional solutions with our partners based on LTE-R technology and even support their entry into overseas markets,” adding, “Through this, we will be able to increase the competitiveness of the LTE-R Comprehensive Verification Center and secure a bridgehead for technology exports.”
U+ also recently succeeded in conducting a mock driving test using actual route environments, ground devices, and onboard devices at the LTE-R Comprehensive Verification Center. Through this, the foundation for upgrading the train control system 'KTCS (Korean Train Control System)-2', which is currently transmitted through a wired network via train tracks, to a wireless network based on LTE-R has been established.
Oh Young-hyun, head of LG Uplus’ wireless business division, emphasized, “The open lab-style LTE-R comprehensive verification center is playing a central role in the LTE-R railway integrated wireless network project, which is essential for industry-academia-research cooperation and technology exchange,” and “We will continue to strive to lead the advancement of domestic LTE-R service quality and technological development.”
Meanwhile, the LG U+ LTE-R Comprehensive Verification Center is an LTE-R test center built in May through a 'Dense Wavelength Division Multiplexing (DWDM)' long-distance transmission network between the LG Science Park in Magok, Seoul (center facility) and the Daejeon R&D Center (field facility).

Railway communications become 10x faster with DWDM devices
SK Telecom has concluded a construction contract with the Korea Railroad Infrastructure Corporation for the "procurement and installation of high-density wavelength division multiplexing (DWDM) devices" for the Gungjang Industrial Complex access railroad and four other projects. SK Telecom, in consortium with Woo-net and others, has secured the contract for the southern high-density wavelength division multiplexing (DWDM) device project, which involves constructing a railroad communication network in southern regions outside the Seoul metropolitan area, including Gwangju, Daejeon, Daegu, and Busan. The contract period extends until December 31, 2020, with a total contract value of approximately 6.8 billion won. DWDM transmission equipment is a device that transmits signals by encoding them onto light wavelengths. All communications ranging from LTE-R, the integrated railroad wireless network, and KTCS for inter-train communication, to security services such as CCTV and computerized communications for train ticket reservations are all conducted through the DWDM network, making it a critical infrastructure for railroad communications.

SK Telecom First Applies AI-Based Network Operations at Gwanghwamun K-Pop Concert
SK Telecom announced that it applied an AI-based network operation system for the first time at a large-scale K-pop concert held in the Gwanghwamun area of Seoul on March 21st, managing communication quality throughout the event. Mobile data usage during the three hours before and after the concert reached 12.15TB, approximately doubling compared to the same time slot the previous weekend. SK Telecom monitored traffic using the AI system 'A-One' in five-minute and 50-meter units to respond to potential overload situations, while also operating temporary communication facilities and on-site personnel in parallel. This case is interpreted as confirmation of the practical applicability of AI-based autonomous network operation in an environment where demand from dense events and foreign users increases simultaneously.
