Open RAN, as a new approach to building mobile networks, offers faster innovation and the possibility of lowering costs. This whitepaper provides an overview of Open RAN in general, and O-RAN specifically. The O-RAN concept, relevant standardization, and ecosystem players are introduced. The architecture as defined by the O-RAN Alliance is described. Near-Real-Time RAN Intelligent Controller (RIC) along with the idea of xApps is discussed. The use cases for O-RAN are overviewed with a particular focus on Traffic Steering.

Like almost everything in Telecom's, Open RAN is complicated. It's not a single idea. It's not a single product or service. It's not an optimization technique or path towards improved efficiency. It’s hardly even an agreed term. Open RAN is essentially 2 foundational ideas: 1) The disaggregation of network functionality from the underlying hardware. 2) The specification of discrete functional blocks having well-defined interfaces. In other words, modularity.
