AmpliTech and Northeastern University Demonstrate First Open-Source Massive MIMO O-RAN System with Category B Fronthaul

AmpliTech Group and Northeastern University have demonstrated the first open-source massive MIMO O-RAN system with Category B fronthaul. The system integrates AmpliTech's commercial-grade radio unit with the OpenAirInterface CU/DU stack, marking the first time a full, end-to-end massive MIMO O-RAN system has been assembled entirely from open, interoperable components. The demonstration validates the system's ability to operate at full performance within a fully open, multi-vendor stack.
