  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.
