Abstract
Disclosed herein is a people-counting system that counts people in a given area based on the signals that are emitted by the respective people's mobile devices, such as cell phones. In order to count passively, the system receives and analyzes network probes transmitted by the wireless devices and correlates groups of fake machine identifiers in order to identify a given device. Where this passive approach is unsuccessful, or determined low certainty, an active approach involving data layer packets such as: CTS/RTS, authentication and dissociation packets. Device's response or lack thereof is analyzed to provide further accuracy to a local device count.
