Validating mMIMO radio transceiver performance up to 64 TRX

Implementing dynamic Massive MIMO (mMIMO) RF beamforming involves sophisticated hardware and software algorithms that must be verified throughout the entire 5G radio design workflow. Critical testing phases include antenna array integration and calibration, beam validation from physical RF signals at layer-1 (L1) in uplink and downlink, and layer-1 / layer-2 (L1 / L2) scheduling in single-user and multi-user transceiver modes.

Testing mMIMO RF beamforming radios requires measuring phase- and time-coherent RF signals across all transmit and receive antenna ports simultaneously. Having more mMIMO RF antenna ports typically increases the time and cost of testing. Therefore, the complex multiport RF test system must be calibrated for phase, time, and amplitude. Consistent results across all workflow test stages are essential for cross-correlation and efficient troubleshooting.
