Abstract
A wireless access device in a wireless network, whether a known or unknown entity, can be located using a geolocation system. A signal strength is determined by a wireless intrusion detection system (WIDS) node in a wireless network for each wireless access device that it detects. Based on the signal strength, an approximate distance from the node is determined, which, in one embodiment corresponds to a radius of a circle around the node. To account for error, an approximation band of the circle is calculated that will allow a user to determine the approximate location of the device within the wireless network.
