Open Radio Access Networks (Open RAN)

1 Day / 2 Live Online Sessions (0900-1230) / Technical Level: Level 1

Course Code: RP2001

Live Online: 30-31 Oct

Open RAN set to transform the Radio Access Networks (RAN) and in turn the Industry that supports it. The ORAN Alliance is working towards an architecture which is open, intelligent, virtualized and fully interoperable with the intention of enabling a more competitive and innovative RAN supplier ecosystem. For the telecommunications operator, Open RAN-compliant mobile networks improve the efficiency and flexibility of RAN deployments and operations – both essential as networks are densified, and as they evolve through the deployment phases of 5G.

This course provides a solid introduction to Open RAN, exploring the purpose, features, architecture, operation and deployment options. The way Open RAN principles, and its foundation in virtualisation, supports the evolution to 5G is also discussed, as well as the impact of using ORAN architecture on both the open and standardised interfaces.
