Abstract: This disclosure provides systems, methods and apparatuses for detecting motion based on one or more wireless signals. In some implementations, a receiving device may receive a first frame and a second frame from a transmitting device, may determine a first channel impulse response (CIR) based on the first frame, may determine a second CIR based on the second frame, may determine a difference between a shape of the first CIR and a shape of the second CIR, and may detect motion based on the determined difference.
