Open RAN Architecture Gains Genuine Commercial Traction
Rakuten Mobile's fully virtualized open RAN deployment has moved beyond proof-of-concept status into genuine commercial validation at national network scale, pressuring established carriers to reconsider decades-old proprietary vendor relationships. This shift reflects growing carrier confidence that interoperable, multi-vendor architecture can deliver comparable reliability to integrated single-vendor systems while restoring meaningful procurement negotiating leverage. Open RAN infrastructure now represents roughly 22 percent of total radio access network deployment, up considerably from a negligible share just a few years earlier as NTT Docomo and KDDI both announced accelerated open architecture rollout timelines following Rakuten's demonstrated commercial success across its national coverage footprint.
