Abstract
The disclosed system for testing a massive MIMO beamforming antenna array of arbitrary size includes an anechoic chamber, and a mount for a MIMO array antenna positioned in the chamber, wherein the array has at least 8×4 antenna elements that are individually activated to steer transmissions from the array. The system includes dual element antenna probes positionable in the anechoic chamber, with feeds coupling one or more UE sources to the antenna probes; and the UE sources generate RF in OTA communication with the array, emulating multiple UE devices. Additionally the system includes base station electronics coupled to the array, and a test controller coupled to the base station electronics. The test controller signals the UE sources OTA via the array to invoke a connection to the UE sources and measure OTA channel performance between the array and the multiple UE devices emulated, the performance including at least throughput.
