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.
◆ ◆ 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.
