Open RAN brings multi-vendor diversity and interoperability to mobile/cellular networks. It is becoming part of governmental strategies for diversifying telecoms supply chains. This paper describes the approach and key achievements of the BEACON-5G project, jointly funded by the UK government and industry. The BEACON-5G project aims at developing a competitive edge for 5G Open RAN and contributing toward its maturity. It addresses some of the key challenges in this respect and provides various innovations for system integration, network slicing, marketplace integration, cyber security, and white-box RAN. It also conducts real-world technology trials for urban use-cases. The paper also captures some of the key lessons learned during delivery, the main outcomes, and highlights potential impact on the wider UK 5G diversification strategy.
