Eridan and OCUDU show Open RAN interoperability in less than a day

Eridan said it integrated its 5G Open RAN radio platform with the latest OCUDU open-source CU/DU software stack in under one day using standard ORAN interfaces. The demonstration is meant to show faster Open RAN interoperability for commercial, private, government, and defense 5G deployments.

Why it matters: - The integration shows how quickly open-source software and U.S.-developed radio hardware can work together on standard Open RAN interfaces. - Faster interoperability can shorten testing cycles for operators, private networks, government users, utilities, defense and critical infrastructure deployments. - The pairing is aimed at reducing energy use and infrastructure costs while preserving carrier-grade performance.

What happened: - Eridan announced successful integration of its 5G Open RAN radio platform with the latest release of the OCUDU open-source CU/DU software stack. - The integration was completed in less than one day. - The work used standard ORAN interfaces. - The combined platform brings together OCUDU’s CU/DU software and Eridan’s Ultra-Clean Signal™ radio technology. - The demonstration supports a broad range of wireless applications, including mobile operator networks, private 5G deployments, government systems, utilities, defense and critical infrastructure. - Eridan also said it has integrated its radio platform with 15 CU/DU solutions.

The details: - Eridan’s radio technology uses a low-power direct polar architecture, according to Dr. Tom Rondeau, Principal Director of FutureG, OUSW(R&E). - OCUDU makes its CU/DU software available as open source. - OCUDU says the software provides a common foundation for testing, validation, feature enhancement and AI-RAN applications across the ecosystem. - Eridan said it is actively contributing to interoperability testing and feature validation within the OCUDU project. - Omid Tahernia, Eridan CEO, said the rapid integration shows progress in Open RAN interoperability and that open interfaces matter only when independent platforms can work together in practice. - Dr. Rondeau said the integration demonstrates the model’s ability to deliver scalable, carrier-grade performance and could help lower the energy footprint and infrastructure costs for commercial 5G and tactical DoW edge deployments. - Eridan builds 5G cellular radios designed to deliver Ultra-Clean Signal™ performance with less power. - OCUDU Ecosystem Foundation is hosted by the Linux Foundation. - OCUDU describes itself as a global public-private initiative focused on building a commercial and research ecosystem around a production-ready open source CU/DU stack. - OCUDU also provides reference architectures, conformance tooling and “super blueprints” intended to help scale Open RAN from pilots to global production. - Eridan is based in Sunnyvale, California.

Between the lines: - The partnership underscores a push in Open RAN toward faster plug-and-play validation, not just theoretical standards compliance. - The mention of AI-RAN, edge deployments and tactical DoW use cases signals interest in both commercial and government markets. - The 15-solution integration tally suggests Eridan is trying to position its radio platform as broadly compatible across the Open RAN ecosystem.

What's next: - Eridan is expected to continue interoperability testing and feature validation with OCUDU. - The companies are positioning the integrated stack for broader use in commercial 5G and edge deployments. - Further ecosystem testing could determine how quickly the approach scales into production networks.

The bottom line: - Eridan’s latest integration is a speed test for Open RAN, and the result is a working radio-software pairing completed in under a day.
