Continued 1Finity and Rakuten collaboration advances global Open RAN adoption
July 13, 2026 – 1Finity, a Fujitsu company and leading global network solutions provider, today announced that Rakuten Mobile has deployed 1Finity compact radios in their fully virtualized commercial nationwide network to support ongoing strategic 5G Sub6 (3.7GHz) network expansion. The Open RAN-compliant, energy-efficient radios are delivering local coverage densification for Rakuten Mobile subscribers across Japan. This deployment, which was completed in May 2026, is based on the rollout plan announced by Rakuten Mobile and Fujitsu in March 2025.
1Finity’s extensive portfolio of 5G radio units (RUs) are designed for outstanding performance, high reliability and energy efficiency. The 1Finity O-RAN-compliant 44R21 RU delivers high power in a compact and lightweight form factor, which helps reduce installation space and lower lease costs.
Building on a proven track record of multivendor interoperability, the 1Finity 44R21 RU has been seamlessly integrated with both Rakuten Symphony’s vCU/DU and Rakuten Mobile’s network management system, empowering more efficient, seamless multivendor management.
“Rakuten Mobile is committed to building the most advanced and efficient cloud-native 5G network, and 1Finity’s high-performance radios are a key component of this strategy,” said Sudhakar Pandey, Head of Rakuten Mobile’s RAN department. “Having recently achieved a significant milestone by surpassing 10 million subscribers, we remain committed to delivering even more high-quality services that enrich our customers’ lives.”
“Our continued work with Rakuten Mobile enables us to support their goals of building a sustainable, open 5G architecture to deliver a high-quality customer experience,” said Patrik Eriksson, Vice President and Head of the Mobile System Business Unit at 1Finity. “This is yet another example of how 1Finity is driving global Open RAN adoption with a robust portfolio of high-performance, energy-efficient radio units.”
