The open RAN venture backed by NEC and NTT DoCoMo has appointed a chief operating officer, a move the partners frame as preparation for scaling the business beyond Japan and into international markets.

The COO appointment signals a shift in emphasis for the venture. To date, the collaboration between the Japanese vendor and the country's largest mobile operator has been closely associated with NTT DoCoMo's domestic 5G network, where NEC equipment has supported the operator's multi-vendor rollout. Naming a dedicated operations chief with a global mandate suggests the partners now intend to treat the venture as an export business rather than a joint development exercise.

That distinction matters commercially. Open RAN promises operators the ability to mix radio units, baseband software and management platforms from different suppliers, loosening the grip that Ericsson, Huawei, Nokia and ZTE have held over radio access networks. In practice, most large operators have moved cautiously, citing integration risk and performance concerns. Ventures that pair a vendor with a tier-one operator — as NEC and NTT DoCoMo have done — are one way the industry has tried to close that credibility gap, using a live carrier network as proof that disaggregated gear performs at scale.

The leadership hire also lands at a moment when the open RAN market is under scrutiny. Early enthusiasm, driven partly by government pressure to exclude Chinese vendors from 5G networks in the US, the UK, Japan and elsewhere, has given way to a more sober phase in which operators demand evidence of total cost of ownership savings rather than architecture diagrams. Vendor marketing around open interfaces remains strong; signed, revenue-generating contracts remain comparatively scarce outside a handful of markets, including Japan, where operators have been among the most aggressive early adopters.

For NEC, the venture is a component of a broader strategy to convert its domestic open RAN credentials into international carrier business, targeting markets where operators are restructuring their vendor supply chains. For NTT DoCoMo, the arrangement provides early visibility into disaggregated network technology and a channel to monetize operational know-how accumulated during its own 5G deployment.

The appointment of a COO is a routine governance step on its own, but in context it indicates the venture is building the management structure needed to run multi-market delivery, support and partner management — functions that scale-out ambitions require and that joint development projects typically do not. Whether the venture converts that structure into carrier wins outside Japan will depend on the same factors that have constrained open RAN uptake generally: integration cost, performance guarantees and the willingness of operators to re-architect supply chains that already work.

The partners have not tied the announcement to a specific rollout deadline or revenue target, but the stated intent is global scale-out, with the new COO charged with turning the venture's Japanese track record into a foundation for international commercial deployment.
