Cambridge Broadband Networks Group in UK collapses after Verizon ends deal
Some 75 jobs at the UK-based Cambridge Broadband Networks Group (CBNG), which developed network technology for mobile and wireless broadband operators, have been cast into uncertainty after the business fell into administration. The situation occurred after the company’s main customer, Verizon, chose not to adopt their mmW product for 5G Fixed Wireless Access (FWA) networks.
So far 2026 is shaping up to be a bad year for UK developers of wireless broadband kit, starting with the recent administration of Cambium Networks (although they were later rescued by the Florida-based Airspan Networks) and now continuing with CBNG.
At the time of writing CBNG’s website appears to have been taken completely offline (it’s currently just a blank page) and the latest details on Companies House show that they have now appointed an administrator – PKF Littlejohn Advisory Limited on 7th October 2026, albeit only publicly confirmed this week.

Stephen Goderski, Partner at PKF Littlejohn, said:
“They had one major customer, and when that major customer decided to go elsewhere, that was the end of the company’s business.”
According to Light Reading, the situation occurred after CBNG lost key partner Verizon. In an emailed statement, Verizon confirmed: “Cambridge offered a technology product that complemented our mmWave solution. As production timelines increasingly fell short, we made the decision to end the relationship with the company, in the best interest of our customers and our business.”

I noted that CBNL and a number of other similar providers were at Connected Britain, almost surprisingly so considering its all about fibre. We know that its not cheap to have a stand there, so a bit of a leap of faith from them.
As someone who bought from CBNL and had always liked what they did, this is a sad reality.
Whilst I know there are still those who see a place for WISPs and their eco system, the reality is that recently we have also lost Cambium, its a tough gig and being reliant on a single major supplier has risks which has sadly come home here.
