UK Chipmaker RANsemi Accelerates Open RAN Plans with New Chairman at the Helm
At this year’s Mobile World Congress, Peter Claydon, CEO of UK-based semiconductor startup RANsemi, shared updates on the company’s role in advancing Open RAN adoption through purpose-built silicon for radio units. “We make semiconductors for radio access networks,” Claydon explained. “Our chips are designed specifically for Open RAN, offering strong performance in a small, cost-efficient package.” RANsemi’s products are now being used in customer deployments across Asia, North America, and Europe, including in the UK, where private network provider Antevia Networks has built a network using RANsemi-powered radios.
One of the key differentiators of RANsemi’s approach is its full support for the O-RAN Open Fronthaul interface, including synchronisation features often challenging to implement. “By integrating synchronisation directly into our chips, we help eliminate one of the major pain points for vendors,” said Claydon. With customer deployments now ramping from thousands to tens of thousands of units, RANsemi is transitioning from R&D to commercial scale. “We’re seeing real momentum now, with third-party validation of both our performance and reliability.”
The company’s growth trajectory is further underscored by the recent appointment of Rupert Baines as Chairman. Baines, a veteran of the UK semiconductor ecosystem, brings deep experience in scaling startups and guiding them through investment rounds, strategic partnerships, and exits. His arrival comes at a key moment for RANsemi, as Open RAN moves from pilot to production
“RANsemi is at a pivotal point in its journey,” said Baines. “I’m delighted to work alongside the team to help realise the company’s potential and create value for stakeholders. As a champion of UK technology, particularly semiconductors, I’m excited to be involved with this new British startup. RANsemi is bringing exciting technology to market and has the opportunity to reshape the landscape of wireless radio access networks.”
