KT Deploys AI-Driven Upgrades in Seoul Ahead of Major Concert for Global Streams
KT says it has strengthened its network infrastructure in central Seoul ahead of a large-scale concert at Gwanghwamun Square and nearby City Hall Square on the 21st. The telecom operator deployed six mobile base stations and installed 79 wireless base stations along with 14 Wi-Fi nodes to significantly expand capacity in the event area.
The company will run an emergency operations posture from its Gwacheon Network Operations Center, with real-time monitoring of upload and download traffic. KT plans to respond immediately to any unexpected variable in the network environment to keep services stable during the event.
About 80 network professionals will be deployed on site, including roughly 40 engineers, to oversee performance and handle contingencies during the performance.
To manage surging traffic from social media uploads and individual live streams, KT will employ its AI-based traffic control system, known as W-SDN (Wireless Software Defined Network). The system is designed to automatically detect overload signs and adjust network resources within about a minute.
W-SDN continuously monitors traffic, performs precise frequency distribution, and modulates base station output to sustain stable operation in large crowds and high-traffic scenarios. KT says this supports reliable networks for both domestic viewers and international audiences watching via global live streams.
KT has also expanded its backbone network capacity well beyond normal levels to accommodate high-definition, high-volume streaming associated with global broadcasts. The goal is to ensure seamless access for viewers in South Korea and overseas.
Oh Taek-kyun, a senior executive in KT’s Network Operation Innovation Division, noted that delivering stable telecom services during large events and global broadcasts is a core responsibility of carriers, and that the company will continue strengthening AI-based network management to ensure reliable service anytime, anywhere.
For international readers, the event illustrates how major telecoms in tech-forward markets are preparing for spikes in demand driven by large public gatherings and global streaming. The approach—mobile base station augmentation, expanded Wi‑Fi coverage, enhanced backbone capacity, and AI-driven traffic control—highlights ongoing efforts to ensure resilient networks that support media distribution, digital services, and cross-border connectivity, with implications for U.S. media producers, cloud services, and policy discussions on network reliability and security.
