KT Begins Field Testing of 5G-V2X Technology on Real Roads

| High-capacity Data Transmission Possible Without Communication Distance Constraints
KT announced on the 17th that it has conducted field testing of 5G-V2X (Vehicle to Everything) technology on actual roads.
in Gangbuk, Seoul using an autonomous bus
KT verified scenarios such as forward collision warnings and pedestrian alerts by installing 5G-V2X terminals in vehicles in the Gangbuk district of Seoul.
Vehicles connect to the C-ITS (Cooperative Intelligent Transport System) platform through the 5G network to receive traffic information necessary for driving.
C-V2X is a technology that identifies and delivers situations in real-time between vehicle-to-vehicle, vehicle-to-pedestrian, and vehicle-to-traffic infrastructure communications.
Since communication occurs directly between vehicle terminals without passing through base stations, there are communication distance constraints, and transmission of large-volume messages is not possible.
Smartphones do not support C-V2X technology, so vehicle-to-pedestrian communication is currently not possible.
5G-V2X overcomes these limitations by combining C-V2X with 5G communication technology.
Utilizing 5G's ultra-low latency and high-capacity data transmission characteristics, various sizes of data can be transmitted without communication distance constraints, and communication between pedestrians and vehicles is also possible using 5G.
KT plans to first verify basic functions focused on vehicle safety using V2X messages through the 5G network, and subsequently expand to functions such as video transmission and other high-capacity data transmission capabilities.
This 5G-V2X technology field testing is being conducted as part of the autonomous driving demonstration project under the Giga Korea initiative, and KT is collaborating with IT Telecom for technology development.
Field testing is scheduled to be completed by 2019, and in 2020 demonstration projects combined with autonomous driving services will be conducted in three regions: Seoul, Daegu, and Pangyo.
Lee Sun-woo, Director of KT's Infrastructure Research Institute, stated, "This 5G-V2X technology field testing is a stage to verify the results of KT's continuous development in preparation for the autonomous driving era," and added, "Going forward, KT will demonstrate its technological capabilities by applying core technologies such as 5G-V2X, autonomous driving, and the C-ITS platform to various demonstration projects."
Ok Kyung-hwa, Head of KT's Software Development Division, remarked, "KT's autonomous driving/C-ITS platform is the first platform to support both direct communication and V2X using the 5G commercial network," and stated, "We plan to continuously enhance it to support safe cooperative driving of fully autonomous vehicles."

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.
