Validated over the O-RAN 7.2x interface, the collaboration combines Eridan’s Ultra-Clean Signal™ radio with SRS’s CU/DU software to deliver high-performance, energy-efficient 5G solutions
SUNNYVALE, Calif. & DUBLIN, Ireland – November 13th, 2025 – Eridan, a technology-driven 5G radio product and solutions company, and Software Radio Systems (SRS), a global leader in open wireless software, have completed the integration of a product-grade 5G gNB (RU + CU/DU) solution designed for commercial deployment.
The collaboration connects Eridan’s fully digital radio unit, powered by its proprietary Ultra-Clean Signal™ technology, with SRS’s carrier-grade CU/DU software stack through the O-RAN 7.2x interface. The joint integration demonstrates validated interoperability, stable high-throughput performance, and energy-efficient operation across U.S. and European test environments. The Eridan RU supports 1024QAM modulation for enhanced downlink capacity, positioning it perfectly for long term scalability and the future of AI growth in mobile networks.
“We prioritize working with partners who see the opportunities through the same lens as we do. Technical performance and efficiency that go hand in hand,” said Doug Kirkpatrick, CTO of Eridan. “SRS has been deeply engaged, bridging two continents to resolve technical challenges, advance the solution for commercial scale, and expand capabilities to new 5G use cases. Together, we’ve built an interoperable foundation that advances open RAN performance and business value for both companies.”
Leveraging SRS’s expertise in carrier-grade RAN software, the integration reflects close collaboration between engineering teams to deliver an end-to-end, performance-driven 5G base station solution. The project underscores how open, standards-based architectures can deliver carrier-grade reliability without compromising efficiency.
“At SRS, we believe interoperability is the key to advancing open RAN without compromising performance,” said Paul Sutton, CEO of Software Radio Systems. “Working closely with Eridan, we’ve validated an integrated solution that brings together robust software and a uniquely efficient radio design. This partnership demonstrates how openness and technical precision can translate directly into commercial readiness.”
This successful collaboration marks another milestone in Eridan’s growing network of strategic interoperability partnerships, reinforcing its goal of ensuring compatibility across the 5G ecosystem. The achievement positions both companies to pursue commercial opportunities and expand into advanced 5G and 5G-Advanced deployments, strengthening the open RAN supply chain and accelerating adoption of energy-efficient wireless infrastructure.
