Abstract
In a general aspect, a method for determining a location of motion detected by wireless communication devices in a wireless communication network includes obtaining motion data associated with a first time frame. The method also includes identifying a first wireless link, of a plurality of wireless links, based on a magnitude of a motion indicator value associated with the first wireless link relative to the other motion indicator values in a set of motion indicator values. The method additionally includes generating a first probability vector based on a predetermined map and the first wireless link and obtaining a second probability vector generated from motion data associated with a prior time frame. The method further includes determining, by operation of a data processing apparatus, a location of motion detected from wireless signals exchanged during the first time frame.
