1Finity completes 5G open RAN radio deployment at Rakuten Mobile in Japan and plans massive MIMO rollout this year; the vendor is also scaling open RAN with AT&T in the US and Vodafone in Europe, marking rare commercial traction for open RAN technology after years of scepticism.

This Wire brief sits within Fusion42's coverage of Semiconductors. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

The Wire takeaway

If you make antenna arrays, power supplies, cooling systems, or baseband processing gear, 1Finity just proved there's a buyer at scale—Rakuten's deployment and AT&T's rollout mean the open RAN bill of materials is now real. Massive MIMO at commercial scale removes the last technical doubt; the suppliers who win these integration slots will set the standard for the next decade of network builds.
