srsRAN: Open Source 4G/5G Software Defined Radio

srsRAN is an open-source collection of 4G and 5G software radio applications developed by SRS. Implemented in portable C++ with minimal third-party dependencies, srsRAN runs on Linux with off-the-shelf compute and radio hardware. The srsRAN Project features a complete O-RAN native 5G RAN CU+DU, and a full-stack 4G network implementation covering UE, eNodeB, and EPC. The project is hosted on GitHub with comprehensive documentation and an active community forum.
