The Linux Foundation launched the Open Centralized Unit Distributed Unit (OCUDU) Ecosystem Foundation at Mobile World Congress 2026 in Barcelona, establishing a new open collaboration hub for carrier-grade CU and DU software in Open RAN. The initiative formalizes OCUDU as the home for open source centralized unit (CU) and distributed unit (DU) code, along with CI/CD and continuous testing assets, to create a foundational reference platform for 5G and early AI-native 6G networks.
OCUDU began with funding from the National Spectrum Consortium (NSC) and the U.S. FutureG Office, which awarded contracts to DeepSig and Software Radio Systems (SRS) to develop the initial software stack. Under the Linux Foundation’s governance model, the Ecosystem Foundation now provides vendors and operators with a structured mechanism to guide development of AI-native, software-defined RAN components. The effort aligns with 3GPP and O-RAN Alliance specifications and complements broader initiatives such as LF Networking, extending open source collaboration deeper into RAN intelligence, automation, and edge orchestration.
Founding members include AMD, AT&T, DeepSig, Ericsson, Nokia, NVIDIA, SoftBank Corp., SRS, and Verizon, alongside 21 general members and 17 research institutions. The foundation aims to scale Open RAN from pilot deployments to production environments by delivering reference architectures, conformance tooling, integration frameworks, and “super blueprints” that support documentation, validation, and end-to-end deployment. Universities and national labs will contribute research in PHY/MAC innovation, AI/ML-based RAN optimization, security, energy efficiency, and reproducible test methodologies to accelerate the research-to-production pipeline.
• Establishes a public-private open source ecosystem focused on CU and DU software for Open RAN
• Hosts the OCUDU Project and related CI/CD and continuous testing frameworks
• Supports AI-based algorithms embedded directly into the software-defined RAN stack
• Aligns with 3GPP and O-RAN standards while operating under neutral Linux Foundation governance
• Includes participation from major operators, silicon vendors, cloud providers, equipment makers, and research institutions
• Targets production-ready 5G and early AI-native 6G deployments
“Open collaboration is essential to accelerating the AI native transformation of the RAN,” said Pallavi Mahajan, Chief Technology and AI Officer at Nokia. “By participating in the OCUDU Ecosystem Foundation, we are deepening our commitment to open, interoperable, software-defined networks. This initiative brings together the best of industry, academia, and government to build a robust foundation for 5G and early 6G innovation. We are proud to contribute our expertise to the OCUDU Ecosystem Foundation, and we are looking forward to working closely with FutureG to help drive the next wave of intelligent, energy-efficient, and globally scalable RAN technologies.”
🌐 Analysis: OCUDU positions the Linux Foundation as a central governance layer for AI-native RAN software at a time when operators and vendors push to industrialize Open RAN beyond trials. The involvement of major silicon suppliers and GPU platform providers signals tighter integration between AI acceleration and baseband software, reflecting broader industry momentum toward software-defined, cloud-native RAN architectures that bridge 5G evolution and early 6G research.
