Abstract
In a general aspect, a method is presented for determining a motion zone for a location of motion detected by wireless signals. In some aspects, the method includes obtaining a time series of statistical parameters derived from sets of channel response data. The method also includes identifying time intervals in the time series of statistical parameters, each time interval associated with a respective motion zone in the space. The method additionally includes determining, by analyzing multiple time windows within each of the time intervals, ranges of motion-zone parameters associated with each respective motion zone. The method further includes storing, in a database of a motion detection system, the ranges of motion-zone parameters for the respective motion zones. The ranges of motion-zone parameters are used to identify one of the motion zones based on a motion event detected by the motion detection system.
