Abstract:
An apparatus for detecting events includes a processor and a storage device storing instructions that when executed by the processor cause the processor to train a classifier for classifying channel state information (CSI) and detecting an event based on the classification of the CSI obtained during a monitoring phase. The training of the classifier includes: for each of the known events to be detected, during a time period in which the known event occurs in a venue, obtain training CSI of a wireless multipath channel between a wireless transmitter and a wireless receiver in the venue, in which the training CSI is derived from one or more probing signals sent from the transmitter through the wireless multipath channel to the receiver, and train the classifier based on the known events and the training CSI associated with each of the events.

Claim (Index 40):
A method for monitoring events using WiFi signals, the method comprising:\n for each of a plurality of known events that may occur in a venue, transmitting at least one WiFi signal from a transmitter to a receiver in the venue during at least one time period when the known event occurs, wherein the WiFi signal comply with IEEE 802.11 standard; for each Win signal received at the receiver, estimating a set of channel state information from the WiFi signal, in which the set of channel state information is associated with the known event that is associated with the WiFi signal; training, using principal component analysis, a classifier based on the known events and the sets of channel state information associated with the known events: and during a monitoring phase,\n transmitting at least one WiFi signal from the transmitter to the receiver during a second time period, \n determining a second set of channel state information from the WiFi signal received at the receiver during the second time period, and \n applying the classifier to the second set of channel state information or data derived from the second set of channel state information to determine which of the known events occurred during the second time period.
