Abstract
Method for testing implicit beamforming operation of a radio frequency (RF) data packet signal transceiver device under test (DUT), including transmitting to the DUT combinations of a multidirectional (e.g., legacy) RF test signal and at least two unidirectional (e.g., beamformed) RF test signals with different signal directivity patterns, and monitoring signal strengths of signals received from the DUT in response to each signal. Signal directivity patterns can be controlled by transmitting multiple phase-controlled RF signals via separate arrays of multiple antenna elements to the DUT within a multipath RF signal environment, such as an electromagnetically shielded enclosure.
