Multi-vendor interoperability: how O-RAN enables it

Breaking Vendor Lock-in

Multi-vendor interoperability is the fundamental promise of O-RAN. The O-RAN Alliance publishes detailed specifications for each interface — fronthaul, E2, A1, O1, O2 — so any vendor implementing these specs can interoperate with components from other vendors. Regular PlugFest events bring vendors together for interoperability testing, while permanent OTIC (Open Testing and Integration Centre) labs in Berlin, Beijing, Washington D.C., Bangalore, and Tokyo provide ongoing certification facilities.
