Fujitsu Showcases Open RAN Progress and AI-RAN Innovation at MWC25

At this year’s Mobile World Congress in Barcelona, Rob Hughes, Head of Wireless Marketing at Fujitsu Network Communications, offered a deep dive into the company’s growing Open RAN portfolio and its next frontier: AI-RAN.

Fujitsu brought a full suite of products to the show, including high-performance Massive MIMO radios, powerful new small cells, and traditional macro solutions. These are already deployed in live networks across the world, with notable partnerships including a joint effort with Ericsson and AT&T to roll out high-power small cells, with broader deployment planned for 2026.

Fujitsu also highlighted its progress on AI-RAN in collaboration with NVIDIA and SoftBank, that has been five years in the making. Leveraging NVIDIA’s super chips, Fujitsu has developed AI-powered algorithms that significantly improve uplink throughput through advanced channel estimation techniques. Real-world use cases like emergency drone dispatch highlight the benefits of ultra-low-latency AI processing at the network edge.

Just as importantly, Fujitsu is also helping operators monetise excess GPU capacity in their networks through “GPU-as-a-service” models integrated with SMO tools.

By supporting open standards, hardware agnosticism, and new monetisation paths, Fujitsu is helping operators leverage the benefits of Open RAN next-generation mobile infrastructure.
