Abstract
A method for Wi-Fi sensing carried out by networked device is described. Initially, first set of time domain pulses is obtained from first channel representation information determined from first sensing measurement based on first sensing transmission transmitted by sensing transmitter and received by sensing receiver. A first amplitude attenuation is detected between first selected time domain pulse of first set of time domain pulses and first corresponding time domain pulse. Further, second set of time domain pulses is obtained from second channel representation information determined from second sensing measurement based on second sensing transmission transmitted by sensing transmitter and received by sensing receiver. A second amplitude attenuation is detected between second selected time domain pulse of second set of time domain pulses and second corresponding time domain pulse. A time lag is determined between first amplitude attenuation and second amplitude attenuation, and near-far indicator is determined based on time lag.
