A system for locating and identifying a mobile device in an environment comprising a plurality of access devices disposed in an environment is provided. Each access device detects a signal strength of a mobile device in relation to the plurality of access devices in addition to a media access control address to identify the mobile device. A trilateration processor computed a distance between the plurality of access devices and the mobile device, and a non-linear regression processor determines the second distance from a sum of errors received from the trilateral processor to establish a location of the mobile device. A wireless network is in communication with the plurality of access devices, the mobile device, and a server to associate the distance with the media access control address of the mobile device.
