Abstract
In a general aspect, motion is passively detected in an environment using wireless signals. In one example, a wireless sensor device that resides outside an environment receives wireless signals transmitted by wireless communication devices that reside inside the environment. One or more sets of motion data are generated, each having a corresponding set of link identifiers. The one or more sets of motion data may be based on beamforming reports in a first subset of the wireless signals and on physical (PHY) frames in a second subset of the wireless signals. The corresponding set of link identifiers may be based on address information in the first and second subsets of the wireless signals. A combined motion data set including the one or more sets of motion data is generated, and motion within the environment is analyzed based on the combined motion data set.
