System and method for identifying stolen wireless devices

摘要

A first antenna configured to receive a signal from each of a plurality of devices. A library contains at least one unique identifier for at least one target device. A second antenna is used to geolocate the target device once the first antenna locates it in the vicinity of the system. A processor is coupled to the first antenna to receive the signal from the plurality of devices and extract the unique identifier from the signal. The processor compares the unique identifier from the signal to the unique identifiers in the library. Upon a match, the second antenna is used to locate the target device.

1. A system for identifying wireless devices, the system comprising:
an omnidirectional antenna operable to receive a signal from each of a plurality of devices; a library containing at least one unique identifier for at least one target device; a directional antenna for locating the at least one target device; a processor coupled to the omnidirectional antenna and operable to receive the signal from each of the plurality of devices and extract the unique identifier from the signal and a strength of the signal, the processor is operable to compare the unique identifier from the signal with the library of at least one unique identifier to identify at least one target device among the plurality of devices, and the processor is coupled to the directional antenna; a user interface coupled to the processor, the processor operable to provide an alert signal to the user interface in response to the unique identifier from the signal being in the library; and wherein the plurality of devices includes the at least one target device and the processor cooperates with the directional antenna to locate the at least one target device based on the strength of the signal from the target device and provides the signal strength to the user interface to locate the at least one target device, and wherein the processor in response to identifying the at least one target device the processor filters out the signal from each of the plurality of devices except for the signal from the target device and removes a remaining portion of the signal from each of the plurality of devices from memory.
