O-RAN specifications for AI RAN, open RAN interfaces, functions and procedures provide the foundation for the industry to supply and innovate in the RAN.
Companies of different sizes and specializations can use O-RAN Specifications to create their innovative and competitive open solutions.
Since 2018, the O-RAN Software Community has successfully jumpstarted open source RAN software, supporting the industry in building open and intelligent RAN.
In 2026, the O-RAN SC is being migrated to the Linux Foundation Networking (LFN). The full integration of O-RAN SC into LFN enables tighter, more efficient, and more streamlined collaboration with fellow LFN projects under a single, unified governance structure.
O-RAN Global PlugFests are periodic events organized and co-sponsored by O-RAN ALLIANCE to enable efficient progress of the O-RAN ecosystem through well-organized testing and integration. Vendors and providers come together to test, evaluate and verify their products and solutions.
Learn about O-RAN PlugFestsThe O-RAN Certification and Badging Program ensures confidence in O-RAN products. Open Testing and Integration Centres (OTIC) provide a collaborative and neutral environment, and are qualified to issue O-RAN Certificates and Badges.
