The company's headquarters are in Cambridge, as part of the Cambridge technology cluster. CBNL also has offices in South Africa, Nigeria and Kenya.

The company's VectaStar product uses its PMP topology to share wireless backhaul and access resource between several cell sites, each generating voice and packet traffic. This technology means spectrum can be managed dynamically and efficiently and can reduce capital and operating costs. VectaStar is used by telecoms network providers across the globe to build a variety of wireless backhaul and access networks. This includes new packet networks; mobile broadband network upgrades; ethernet enterprise networks and 2G - 3G IP backhaul migration. VectaStar delivers up to and over 300Mbit/s full duplex per sector and is deployable in 2G, 3G, 4G, small cell and Long Term Evolution (LTE) backhaul networks.

The company offers services including network planning and design; network deployment; network operation; customer training; 24-hour customer support and WEEE recycling.

Cambridge Broadband Networks Ltd (CBNL) was established in the year 2000 when ten engineers from Cambridge University secured private equity funding to develop an innovative solution to the increased demand for mobile communications.

From this vision, CBNL developed its VectaStar platform which established the company as the clear market leader in point to multipoint microwave space. Indeed, VectaStar networks have been deployed by service providers in over 50 countries for mobile backhaul, small cell backhaul, enterprise access and ISP networks. CBNL’s customers include over 100 service providers, including seven of the world’s top ten mobile operators.

The period of 2005-10 saw the Company grow 864 per cent - growth which ranked the Company in the top 200 on the Deloitte Technology Fast 500 EMEA 2010, a ranking of the 500 fastest growing technology companies in EMEA, and reaching number 38 in the Sunday Times Microsoft Tech Track 100 in 2011.In November 2011 the Company supplied microwave radio equipment to backhaul Telefónica UK's O2 4G trial network in London, UK.[6]

In early 2020, driven by the need to meet the evolving challenges of the licensed point to multipoint, fixed wireless access market, CBNL was restructured into two new companies. As a result, Cambridge Broadband Networks Group (CBNG) Ltd and Cambridge Broadband Networks Limited Africa were formed.

In April 2012 CBNL announced that it had been accepted as a member of the Small Cell Forum,[7] a not-for-profit membership organisation that seeks to enable and promote small cell technology worldwide. CBNL has since been appointed Vice Chair of Small Cell Forum Backhaul Special Interest group.

As a member of Next Generation Mobile Networks (NGMN) Alliance, CBNL recently led a mixed group of both operators and vendors to generate consensus around the specific needs for Small Cell backhaul technology. Results from this work were published in July 2012 in the NGMN Alliance's white paper ‘Small Cell Backhaul Requirements’.[8]
