Samsung and KT Validate AI-RAN Optimisation on Live Networks, Paving the Way for 6G

Samsung and South Korean telecoms operator KT have achieved a significant breakthrough in network optimisation by demonstrating the effectiveness of AI-RAN technology on live commercial networks. This landmark trial confirms that artificial intelligence can maintain stable connectivity even in challenging environments—an essential capability as network usage patterns become increasingly dynamic. The achievement not only marks a step forward for 5G reliability but also lays the groundwork for the future of 6G connectivity.

AI-RAN: A Game-Changer for Network Performance

The conventional approach to network management often involves applying a one-size-fits-all configuration across entire cell sectors. This can result in suboptimal performance, especially when users are located in diverse conditions—such as stationary in areas with strong signals or moving rapidly through zones with interference. Samsung and KT aim to revolutionize this model with AI-RAN optimisation, which customizes network settings for individual devices in real time based on changing conditions. By using predictive analysis, the AI evaluates factors such as user movement, connectivity history, and environmental challenges to anticipate potential disruptions and adapt proactively.

The trial conducted by Samsung Research and KT’s Future Network Laboratory focused on the city of Seongnam, Gyeonggi Province, involving approximately 18,000 users. Historically, many of these users had experienced frequent connection interruptions, providing an ideal testbed for AI-RAN technology. Results revealed significant improvements in connection reliability, with reductions in disruption not only for targeted users but also for others sharing the same network region. This indicates that optimizing for edge cases boosts overall network performance.

Paving the Path to 6G Excellence

As data demands surge and 5G still transitions to maturity, the implications of AI-RAN extend far beyond its current applications. This technology offers a glimpse into the capabilities of next-generation, software-defined networks that will prioritize adaptability, user-specific configurations, and seamless service continuity in complex mobility scenarios. Looking ahead, 6G networks will need to manage higher data volumes and increasingly sophisticated connectivity needs. AI-driven solutions like AI-RAN will be integral to meeting these challenges without sacrificing reliability.

According to JinGuk Jeong, Executive VP and Head of the Advanced Communications Research Center at Samsung Research, “This is a major milestone that shows how AI can improve user experience on real-world commercial networks.” Similarly, Jong-Sik Lee, Executive VP and Head of the Future Network Laboratory at KT, emphasized, “This achievement demonstrates that AI can transform network operations around users. Together with Samsung, we will continue developing customised optimisation technologies to deliver stable, uninterrupted service and drive core 6G capabilities.”

Implications for the Telecom Industry

The validation of AI-RAN highlights the increasing role of predictive analytics and software-defined solutions in telecom infrastructure. By leveraging AI, operators can achieve better service-level agreements (SLAs) for mobile workforces and IoT-connected assets, ensuring robust connectivity even in traditionally weak signal areas. These advancements will be critical for enterprises evaluating telecommunications partners as AI-driven networks become the standard for high-mobility and high-volume data environments.

The collaboration between Samsung and KT exemplifies how partnerships between technology innovators and service providers can redefine network capabilities. With the revolutionary potential of AI-RAN now established, industry stakeholders have a clear direction for realizing the next wave of connectivity advancements, from smarter automation to seamless global communication in the 6G era.
