Abstract
In a general aspect, a method for determining motion zones in a space traversed by wireless signals. In some aspects, the method includes obtaining, over a time frame, sets of channel response data based on wireless signals communicated over wireless links through a space between wireless communication devices. A time series of statistical parameters is generated for each wireless link based on a respective set of channel response data. The method additionally includes determining a plurality of motion zones in the space based on changes in the time series of statistical parameters for each wireless link. Sets of motion-zone parameters are generated that characterize respective motion zones of the plurality of motion zones. The method further includes storing, in a database of a motion detection system, the plurality of motion zones and sets of motion-zone parameters. The sets of motion-zone parameters are used to identify one of the plurality of motion zones based on a motion event detected by the motion detection system.
