Latest release expands network performance, deployment flexibility, and positioning and security for open source software for CU/DU – explored during the upcoming OCUDU Ecosystem Developer Summit Oct. 20-22 near Washington, D.C.
Summary
SAN FRANCISCO, Oct. 8, 2026 – The OCUDU Ecosystem Foundation, a collaborative initiative hosted by the Linux Foundation to advance the open source RAN ecosystem, today announced the availability of OCUDU 26.10. The OCUDU technical project’s new release significantly expands the capabilities of the project’s open source CU/DU platform with 3GPP Release 17 Non-Terrestrial Network (NTN) support, 8T8R MIMO, enhanced beamforming and multi-beam operation, O-RAN Split 7.2b, native 5G positioning and new capabilities designed to reduce latency and strengthen security.
The release reflects the growing breadth of open source RAN technology as operators, vendors, researchers and governments explore more flexible approaches to advanced wireless infrastructure. By extending the platform across terrestrial and satellite connectivity, higher-order antenna configurations, positioning and additional O-RAN architectures, OCUDU 26.10 gives developers and implementers more options for building and testing sophisticated 5G networks while establishing a foundation for emerging 6G use cases.
“Open source RAN is advancing from foundational implementations toward increasingly sophisticated capabilities that can support a much wider range of real-world networks,” said Arpit Joshipura, general manager, networking, edge and IoT at the Linux Foundation. “OCUDU 26.10 brings together important advances in satellite connectivity, radio performance, positioning and interoperability in an openly developed platform. Since the OCUDU Ecosystem Foundation launched within the Linux Foundation, it has welcomed 95 new members and doubled the OCUDU Technical Project’s active contributor count, while participating organizations have expanded tenfold, providing the industry with a shared foundation to drive the future of 5G and next-generation networks."
Key capabilities of OCUDU 26.10 include:
“OCUDU 26.10 introduces Split 7.2b, enhanced MIMO and satellite NTN,” said Ismael Gomez, chair of the OCUDU Technical Steering Committee and CTO of SRS. “Thank you to the community, whose feedback and contributions are strengthening the project and expanding its capabilities.”
OCUDU 26.10 is available now.
OCUDU Ecosystem Developer Summit 2026
The OCUDU community will come together October 20-22 in Alexandria, Virginia, for the OCUDU Ecosystem Developer Summit, co-hosted with Virginia Tech and the Commonwealth Cyber Initiative. The three-day event will bring developers, researchers, operators, vendors and ecosystem partners together for technical collaboration, hands-on learning and discussions around open source RAN, real-world deployments, integration and the future of 5G and 6G wireless innovation.
Developers can explore the new release with the engineers who built it at the OCUDU Ecosystem Developer Summit, taking place Oct. 20-22 in Alexandria, Virginia. To learn more about the OCUDU Ecosystem Foundation and contribute to the OCUDU technical project, visit gitlab.com/ocudu.
The OCUDU Ecosystem Foundation, hosted by the Linux Foundation, is an open collaboration hub dedicated to building, scaling, and sustaining the OCUDU technical project and its associated ecosystem. The Foundation brings together communications service providers, technology vendors, silicon providers, cloud providers, system integrators, research institutions, and the open source community to accelerate the development and adoption of open, interoperable, cloud-native radio access networks through collaboration, reference architectures, validation, CI/CD/CT infrastructure, and ecosystem alignment.
