Abstract
A computer-implemented method comprising: monitoring transmissions representing estimation of a wireless channel, between at least one wireless access point (AP) and a plurality of wireless stations (STAs); at a training stage, training a machine learning model on a training dataset comprising: (i) a plurality dataframes of a standard beamforming protocol associated with at least some of the monitored transmissions, and (ii) labels indicating an association between the dataframes and the STAs; and at an inference stage, applying the trained machine learning model to a target transmission representing estimation of a wireless channel, to predict whether the target transmission was transmitted from one of the STAs.
