The Open RAN concept is about disaggregating the RAN functionality by building networks using a fully programmable software-defined mobile network solution based on open interfaces – radios, base stations, etc. – that runs on commercial, off-the-shelf hardware (COTS) with open interfaces. The Open RAN concept and movement is not new – mobile operators and network and technology vendors have been developing solutions, conducting trials and deploying networks for the last few years.
This white paper, which was sponsored by Altiostar, Mavenir and Parallel Wireless, provides an overview of the Open RAN ecosystem and basic architecture. The white paper also discusses the industry challenges that drive its implementation and the resulting benefits of its deployment, and includes several case studies of successful Open RAN deployments.
