A privacy-enhancing wireless communication method for use by a transmitting wireless device having a first location, the method comprising: obtaining a frame preamble using a transceiver device at a location, wherein the frame preamble includes a predetermined pattern and wherein movement information corresponding to the location is detectable based on channel state information of the transceiver device in accordance with the pre-determined pattern; modifying the predetermined pattern of the frame preamble to include amplitude or phase distortion; and masking the movement information by transmitting, using the transceiver device, a frame including the frame preamble with the modified predetermined pattern.
