The National Telecommunications and Information Administration (NTIA) awarded Cirrus360 LLC a $2,120,140 Project Grant under the Public Wireless Supply Chain Innovation Fund Grant Program (CFDA 11.038). The purpose of the grant is for Cirrus360 to develop a new test method that uses a digital twin of integrated radio access network (RAN) components to model system implementation and identify potential issues. Key activities include demonstrating efficient testing via formal traffic constraints and digital twinning, integrating identified bugs into the digital twin model, and creating documentation to enable stakeholders to use the new test method. The expected outcome is an automated test framework that addresses multivendor interoperability and deployment-specific optimizations for open RAN systems, which is critical for reducing the cost and complexity of RAN integration and testing. Cirrus360 will collaborate with partners to test the new method in their distributed unit (DU) and testbeds. The grant period of performance is from January 15, 2024 to July 14, 2026.
