Abstract
Systems and methods for Wi-Fi sensing are provided. A networking device is configured to transmit a sensing trigger message including information about a plurality of fast sounding sensing signals to be transmitted. The networking device receives the plurality of fast sounding sensing signals transmitted by a sensing transmitter in response to the sensing trigger message within a transmission opportunity. The networking device performs a plurality of sensing measurements on the plurality of fast sounding sensing signals wherein the plurality of sensing measurements include measurements of Doppler frequency information associated with motion in a sensing space.
