South Korea mobilizes AI-enabled networks for BTS comeback concert in Seoul

South Korea’s three leading mobile operators are staging a coordinated, AI-enabled network response ahead of a high-profile BTS comeback concert on the 21st at Gwanghwamun Square in central Seoul. The event is drawing tens of thousands of attendees and is a stress test for the country’s 5G and broadband networks, with operators deploying temporary infrastructure and advanced traffic management systems.

SK Telecom says it will activate its AI-based network operating system, called A-One, for the first time to design an optimized communications environment for the concert. On the day of the show, SKT will monitor现场 traffic in real time to respond to surges in user connections, changes in network quality, and equipment anomalies. The operator is adding temporary facilities to boost capacity and is installing extra, zone-based network configurations to target different areas around Gwanghwamun and Seoul City Hall.

KT Corp. will run an emergency operations posture from its Gwacheon Network Operations Center, with live monitoring of upload and download traffic and immediate response to any unexpected changes. About 80 network professionals will be deployed, including around 40 engineers. KT is applying an AI-based traffic control system known as W-SDN, designed to detect load-related issues at base stations and autonomously adjust traffic within a minute.

In the field, KT is placing six mobile base stations and installing additional wireless base stations and Wi-Fi access points to expand capacity. Specifically, the plan includes six mobile sites plus 79 wireless base stations and 14 Wi-Fi units in and around the event areas to accommodate surges in data usage from on-site fans and live streaming.

LG Uplus is leveraging autonomous network technology to forecast traffic fluctuations before and during the event. The company will operate from a command center connected to a field operation team, coordinating traffic management in real time. It is deploying mobile base stations and temporary relays at around ten locations in and near Gwanghwamun Square and Seoul City Hall, alongside pre-event optimization of existing base stations. On the day of the concert, LG Uplus will staff on-site personnel and a Magok Network Situation Room to monitor conditions and implement immediate optimizations as needed.

Police and city officials estimate that the event could draw up to about 260,000 people, including around 22,000 ticket holders. Major road closures around the venue are expected to funnel crowds into confined spaces, making robust mobile and wireless coverage crucial for safety, security communications, and real-time information.

The arrangements illustrate how South Korea’s telecoms sector uses AI, portable infrastructure, and centralized command centers to maintain service quality for mass gatherings. For U.S. readers, the approach highlights methods that could inform large-scale event planning, network resilience, and disaster-response strategies in the United States, where similar challenges arise for sports games, concerts, and other major public events. It also underscores ongoing global interest in AI-driven network management as 5G and future wireless technologies continue to evolve and expand capacity for high-demand environments.
