OpenAirInterface Software Alliance

The OpenAirInterface Software Alliance (OSA) is a non-profit consortium fostering a community of industrial as well as academic contributors for open source software and hardware development for the end-to-end 4G, 5G and beyond 3GPP cellular networks. The OpenAirInterface (OAI) software includes implementations of the core network (CN), the access network (RAN) and user equipment (UE). More recently, it further includes Orchestration and Management (O&M) as well as RAN Intelligent Control (RIC) software and cloud-native deployment frameworks.

Today the OAI stack is a leading exemplar open reference design for 3GPP and Open RAN specifications with broad adoption across Academia, Industry, as well as government organizations particularly in many parts of the globe.
