1. A method for classifying motion, by a first wireless local area network (WLAN) device, the method comprising:
transmitting, by the first WLAN device, a sounding packet to a second WLAN device, the first WLAN device being a WLAN Access Point (AP) and the second WLAN device being a WLAN AP;
receiving, from the second WLAN device, an acknowledgement (ACK) of receiving the sounding packet by the second WLAN device;
using the received ACK, determining Channel State Information (CSI) for a radio frequency (RF) signal path between the first WLAN device and the second WLAN device;
aggregating the determined CSI with additional CSI; and
determining, using the aggregated CSI, a presence or a motion within a structure for classification.
