At the heart of this solution is an external control server that collects user distribution data every minute from deployed base stations. An AI model analyzes these data — including beam estimation and spatial distribution signals — to automatically determine whether an event or change in traffic patterns is occurring. From there, it dynamically selects the optimal coverage pattern for the Massive MIMO arrays without human intervention.<\/p>
This real‑time external control approach allows the system to adapt its radio footprint based on observed usage rather than static scheduling, providing flexibility and sustained network performance under varied conditions.<\/p>
One of the most compelling validations of this technology came from deployment at the Expo 2025 Osaka venue, where SoftBank and Ericsson tested the AI‑driven coverage system in outdoor areas highly susceptible to traffic variability. The results showed an approximate 24 % increase in downlink throughput (from 76.9 Mbps to 95.5 Mbps) during periods of rapid traffic changes compared with conventional operation — a significant improvement in user experience and network efficiency.<\/p>
This gain not only enhanced peak data speeds but also helped mitigate the phenomenon known as “packet stalling”, where congestion during sudden surges in usage can slow or freeze data traffic altogether.<\/p>

At such sites, traffic distribution may differ dramatically between off‑peak times and event periods, requiring base stations to behave in a highly flexible manner to maintain performance. The AI system’s ability to detect and respond automatically provides significant advantages over static coverage strategies.<\/p>

This venture is a big leap for the application of artificial intelligence to radio access network (RAN) operations. It facilitates the improvement of communication performance and adaptability in scenarios where user traffic changes rapidly.The system builds on successful trials conducted during Expo 2025 Osaka, Kansai, Japan, demonstrating uplifts in coverage performance and responding dynamically to fluctuations in user demand — a capability that conventional preset configurations often fail […]<\/p>\n","protected":false},"author":7,"featured_media":27444,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"wprm-recipe-roundup-name":"","wprm-recipe-roundup-description":"","postBodyCss":"","postBodyMargin":[],"postBodyPadding":[],"postBodyBackground":{"backgroundType":"classic","gradient":""},"footnotes":""},"categories":[189,92,8098],"tags":[1030,2300,1675,11142,774],"ppma_author":[572],"class_list":["post-27443","post","type-post","status-publish","format-standard","has-post-thumbnail","category-cloud-communications-martech","category-martech","category-news-articles","tag-5g-network","tag-cloud-communications","tag-ericsson","tag-mimo-coverage","tag-softbank"],"yoast_head":"\n\u5c06\u6765\u306e5G\u3068\u305d\u306e\u5148\u3078\u306e\u793a\u5506<\/strong><\/h3>
