Abstract
A method for assessing receiver signal reception performance during wireless beam steering operation of a radio frequency (RF) data packet signal transceiver capable of multiple input, multiple output (MIMO) operation. In response to transmissions of a sounding packet (SP) from a beamforming device ('beamformer'), a receiving device ('beamformee') transmits a response data packet containing matrix data representing a beamforming feedback matrix (BFM) related to signal attenuation by the wireless signal path environment through which the beamformer and beamformee are communicating. Using the matrix data, a statistical variation can be computed which is indicative of signal reception performance of the beamformee.
