What OpenAirInterface does
OpenAirInterface Software Alliance (OSA) is a non-profit endowment fund (Fonds de dotation) established under French law in November 2014 at the initiative of EURECOM, headquartered at Campus SophiaTech in Biot, France. The organization develops and maintains the OpenAirInterface (OAI) platform — an open-source, 3GPP-compliant cellular networking stack covering 4G LTE and 5G NR radio access networks (gNB, UE), 5G standalone core network with Service-Based Architecture functions (AMF, SMF, UPF, NSSF, AUSF), and an O-RAN-aligned Operations, Administration & Management (OAM) platform including the FlexRIC near-real-time RIC and xApp framework. The software runs on commercial off-the-shelf hardware with interoperability to commercial devices and is distributed under the Collaborative Standards Software License (CSSL) and 3-Clause BSD licenses.
The platform serves four primary user segments: academic and research institutions conducting 4G/5G/6G research; telecom operators seeking open-source reference implementations to avoid vendor lock-in; network equipment and semiconductor vendors (Ericsson, Qualcomm, Nokia, NVIDIA, Red Hat, InterDigital) using OAI for product development and interoperability testing; and system integrators/SMEs (Allbesmart/OAIBOX, BubbleRAN, Firecell, Phine.tech) building commercial 5G products and private network solutions on top of OAI. The organization does not sell software; revenue derives entirely from membership contributions, with strategic partners paying a minimum of €40,000 annually and associate partners €10,000 (€2,500 for qualifying SMEs).
OpenAirInterface maintains a core engineering team of full-time staff supported by global community contributions, and has grown over a decade to become the self-described fastest-growing open source community in cellular wireless, with tens of thousands of users across academia, research, and industry. Recent strategic developments include the August 2025 launch of the Duranta incubation project with Linux Foundation Networking, the establishment of the OAI Foundation as a separate entity in November 2025, a September 2024 partnership with Canonical for cloud-native Open RAN, and an AI-driven 6G roadmap incorporating NWDAF analytics, LLM-based scheduler generation (ALLSTaR), and GPU-accelerated Layer 1 processing via NVIDIA Aerial integration.
