ABSTRACT:
A system and method for locating a wireless device in one or more wireless networks within a selected geographic region. The method includes generating a computer model of a selected geographic region including a layout and inputting information associated with one or more components of a wireless network into the computer model. The one or more components includes at least one or more sniffer devices. Additionally, the method includes determining signal intensity characteristics of the one or more components of the wireless network over at least a portion of the selected geographic region and receiving one or more wireless signals from one or more wireless devices. Moreover, the method includes determining a plurality of probabilities associated with a plurality of locations for at least one of the one or more wireless devices.
