Samsung Electronics at present introduced the profitable trial of its AI-powered RAN Speed Optimizer (RSO) on KDDI’s business 5G Standalone (SA) community in Japan. The joint trial, which started in late 2025 and lasted for a number of months, demonstrated how AI options can ship advantages in each day operations and actualize a transformative leap in enhancing community efficiency.
Conducted in and round Tokyo, spanning dense city, suburban and rural areas, the take a look at leveraged 100 MHz of three.7 GHz TDD spectrum throughout a whole lot of cells. The numerous visitors and community environments allowed sturdy AI mannequin coaching to be carried out throughout real-world situations. During peak hours, Samsung’s RSO delivered a median enhance of 31% in 5G downlink throughput throughout the general trial space, with good points reaching a most enhance of 52% in dense city areas. In addition to substantial efficiency good points, the trial highlighted the potential and effectiveness of AI-based options to allow extra exact and adaptive community optimization in business environments.
Samsung’s AI-powered RSO is constructed to reinforce community efficiency by way of distinctive parameter optimization per cell. This is a major change and development, the place AI-tuned customization strikes past the standard cluster-level method that applies the identical parameter settings throughout a number of cells. Samsung’s RSO makes use of its personal AI-based prediction mannequin to investigate web site surroundings information routinely and suggest optimized parameters tailor-made to every particular person cell. The RSO is a part of the Samsung CognitiV Network Operations Suite (NOS), a set of numerous AI-powered community automation options, AI brokers and clever functions.
This trial advantages operators by routinely adjusting to altering situations throughout completely different community eventualities, permitting for diminished guide intervention and higher value effectivity. For finish customers, this implies quicker and extra dependable connections whether or not they’re streaming movies, searching the net or making calls.
“Combining KDDI’s accumulated expertise in network innovation and Samsung’s technical leadership, this field trial proves that individual tuning for cells — a long-standing industry challenge — has now become a reality through the integration of AI,” stated Kazuhiro Furuhata, Chief Network Officer at KDDI. “Moving forward, we remain committed to pushing the boundaries of AI-based technologies to continuously elevate network experience for our customers.”
“Samsung continues to help operators like KDDI build intelligent and efficient networks by weaving in AI-powered innovation,” stated June Moon, Executive Vice President, Head of R&D, Networks Business at Samsung Electronics. “Since 2024, we have been actively testing and training our AI-powered RSO technology in the field and we have demonstrated breakthrough progress in its capabilities. This trial with KDDI exemplified how Samsung’s AI-powered innovation can bring advanced optimization to live commercial networks while facilitating steady, seamless connectivity in an array of different network environments.”
Building on this profitable trial, Samsung and KDDI plan to proceed evaluating AI-based optimization applied sciences for broader business community functions. The corporations’ long-standing collaboration on absolutely virtualized community deployments offers KDDI with an optimum basis for advancing towards AI-native community operations.
