Open RAN contains multitudes. It’s an ideological movement grounded in the belief that a diverse radio supplier ecosystem begets competitions which begets advantageous economics which begets more and faster innovation. It’s an ongoing and collaborative process of standardizing interfaces between different parts of a radio system. And it’s also very much an exercise in performance and interoperability testing that lets an operator stitch together different pieces of hardware and software, then confidently deploy in a commercial network.
