🧠AI Telecom: Samsung and KT Take 6G AI-RAN Out of the Lab and Onto Live Networks
Samsung Electronics and KT Corp. have achieved a key milestone in next-generation communications by validating 6G AI-RAN technology on a live commercial network. The successful field trial demonstrates that AI-driven network optimization can operate reliably outside laboratory environments, maintaining stable performance under everyday user conditions.

The trial was conducted in selected areas of Seongnam (Gyeonggi Province, south of Seoul), covering approximately 18,000 active mobile users per day. By testing across diverse signal and environmental conditions, the companies confirmed that AI-RAN delivers consistent connectivity even in challenging real-world scenarios such as mobility between cells, fluctuating traffic loads, and variable signal strength.
Unlike conventional networks that apply uniform configurations to all users, AI-RAN dynamically analyzes individual user movement patterns, historical connection disruptions, and real-time signal quality. It then predicts potential connection degradation and proactively adjusts network parameters on a per-user basis. During the trial, users with frequent disconnection histories experienced a significant reduction in service dropouts, while overall network stability also improved for nearby users.
This marks the first live commercial deployment of AI-RAN optimization, following simulation-based verification completed earlier this year. Samsung and KT emphasized that such autonomous, adaptive control will be essential for the 6G era, which is expected to support data-intensive services including XR, autonomous mobility, dense IoT environments, and mission-critical low-latency applications.
This field success also fits into Samsung’s broader global AI-RAN strategy. In October, Samsung Electronics signed a memorandum of understanding (MOU) with SoftBank Corp. to jointly research next-generation communications technologies, including 6G and AI-RAN. The collaboration focuses on areas such as AI for RAN, AI–RAN orchestration, and large telecom models, underscoring Samsung’s intent to scale AI-native network technologies beyond domestic trials and toward global commercialization.
Together, the live-network validation with KT and the strategic partnership with SoftBank position Samsung at the center of emerging AI-driven 6G ecosystems, as standardization discussions and international collaboration intensify.
