| contents | We present ProtO-RU, the first open source, software-defined O-RAN Split-7.2 Radio Unit built using SDRs and commodity CPUs. Unlike proprietary hardware-based commercial O-RUs, ProtO-RU is built on the open-source srsRAN software stack, and it is fully programmable. We demonstrate that ProtO-RU integrates with the srsRAN and OpenAirInterface5G CU/DU stacks, supports both TDD and FDD duplexing modes, and interoperates with commercial 5G UEs. Our evaluation shows that ProtO-RU remains stable under sustained load with multiple UEs and delivers throughput comparable to Split-8 and commercial O-RUs. ProtO-RU opens up new opportunities for RU-level innovations and lowers the barrier of entry for end-to-end O-RAN research. |
