• The OCUDU Project is the home to CU and DU open source RAN software; the Ecosystem Foundation and associated assets for CI/CD/CT to establish foundational code base for 5G and early 6G
• Global industry leaders AMD, AT&T, DeepSig, Ericsson, Nokia, NVIDIA, Softbank Corp., SRS and Verizon along with 21 general members and 17 research institutions join as founding members to spearhead this private-public partnership enabling direct access to the AI Native OCUDU software-defined RAN solution upon which to build and innovate 5G and early 6G networks solutions and applications

BARCELONA, Spain (Mobile World Congress 2026) — 1 March, 2026 — The Linux Foundation (LF), the world’s leading home for open collaboration on open source software, hardware, standards, and data, today announced the formation of the Open Centralized Unit Distributed Unit (OCUDU) Ecosystem Foundation, an open collaboration hub dedicated to building, scaling, and sustaining the OCUDU technical project assets and leveraging them to establish a foundational reference platform for RAN including AI based algorithms and solutions. The OCUDU Ecosystem Foundation provides a critical mechanism for industry vendors to optimally guide OCUDU development to support 5G and early AI Native 6G services.

OCUDU started with an investment from the National Spectrum Consortium (NSC) and the FutureG Office, which awarded funds to AI Native wireless company DeepSig and Software Radio Systems (SRS) to build the initial software for OCUDU.

The OCUDU Ecosystem Foundation brings together an ecosystem across enterprise, telecom operators, cloud providers, equipment vendors, and research institutions to co-develop and integrate critical components required for 5G and early 6G deployments. This community-driven model complements global standards from 3GPP and O-RAN alliance and industry alliances like AI-RAN alliance. This global effort ensures that innovation, transparency, and interoperability remain at the core of global software-defined RAN evolution.

“By aligning global efforts under the Linux Foundation, we’re building an open, trusted, and secure open source platform to power the next decade of wireless innovation,” said Arpit Joshipura, general manager, Networking, Edge and IoT, at the Linux Foundation. “The OCUDU Ecosystem Foundation represents a key step forward in open source RAN, specifically for CU and DU.”

“This initiative brings the best of the open source model to one of the most critical layers of future wireless: the foundation for an interoperable, software-defined radio access network,” said Dr. Tom Rondeau, principal director for FutureG. “By shifting the maintenance of these common components to a collaborative, open-source project, under neutral governance at the Linux Foundation, we enable our industry partners to focus their resources on the innovative and monetizable technologies that are most effective for the nation. We are building a foundation that enables shared success and accelerates progress for the entire ecosystem. We are looking forward to seeing this approach provide a vital platform for strengthening our relationships and collaboration with our allies and international partners.”

“The key to driving innovation in wireless is to leverage a broad ecosystem of experts in networking, radio software, and emerging AI technologies,” said Joe Kochan, CEO of NSC. “What started with a competitive proposal process to elicit the best technology solutions from among NSC’s large and diverse membership is now expanding under the Linux Foundation, and NSC is proud to continue partnering with both LF and the FutureG team to advance OCUDU development efforts and build the next generation of wireless capabilities.”

General members of the OCUDU Ecosystem Foundation include 1Finity, Aalyria, Abside Networks, Airspan, Altio Labs, Booz Allen, Cirrus360, Cisco, Cohere Technologies, ISCO International, JMA Wireless, Keysight Technologies, Marvell, ORAN Development Company, Raycom Wireless, Radisys, Red Hat, Sempre.ai, Skylark Wireless, T-Mobile, and Viavi.

Key Objectives of the OCUDU Ecosystem Foundation

Create a public-private commercial and research ecosystem and an open source stack for open source CU and DU (part of Open RAN)
House the OCUDU Project and other associated open source projects over time
Foster global collaboration across all areas in the RAN along with end-to-end solutions based on super blueprints across other open source foundations (including documentation, testing, integration and the creation of other artifacts) that aid the development, deployment, operation or adoption of the open source project.

The OCUDU Ecosystem Foundation combined with ongoing open networking initiatives such as LF Networking (LFN) extends the open source communities deeper into RAN intelligence, automation, and edge orchestration.

University Participation and Research & Labs Collaboration

The OCUDU Ecosystem Foundation also welcomes participation from universities and research labs to help strengthen the initiative’s research-to-production pipeline and workforce development. By bringing academic partners into the same open governance model as industry and government stakeholders, the Foundation will accelerate applied research, reproducible experimentation, and validation of CU/DU innovations in real-world environments. University collaborators can contribute to areas such as next-generation PHY/MAC research, AI/ML-driven RAN optimization, security and resilience, energy efficiency, and test methodologies, while helping to educate and grow the next generation of open source RAN engineers. Participating institutions include Georgia Tech Applied Research Corporation, Idaho National Laboratory, Iowa State University of Science and Technology, Mississippi State University, North Carolina State University, Northeastern University, Rice University, SRI International, Texas A&M University System, The MITRE Corporation, UC San Diego, UNH Interoperability Labs, University of Notre Dame, University of Texas at Austin, University of Texas at San Antonio, University of Utah, and VT Research Contracting Services.

"Through the U.S. National Science Foundation (NSF) Platforms for Advanced Wireless Research (PAWR) program and other wireless infrastructure efforts, NSF has spent years fostering an open-source environment and has played a crucial role in supporting the early development of infrastructure that enables open-source wireless research," said Behrooz Shirazi, NSF Senior Science Advisor. "OCUDU will build on these efforts with the support of partnering universities and scale them to create a global, production-ready research ecosystem."
