Abstract
Described are a method and system for determining a location of an unauthorized wireless access point (“AP”) accessing a communication network. Upon notification of existence of the unauthorized AP, at least three authorized APs of the communication network initiate tracking a beacon of the unauthorized AP. A tracking data record is generated partially based on information obtained during the tracking of the tracking beacon. The tracking record may include a location of each of the authorized APs and at least one of (i) a first strength data corresponding to a strength of the tracking beacon as measured by each of the authorized APs and (ii) a first time data corresponding to a time period that it takes for the tracking beacon to arrive at each of the authorized APs. The location of the unauthorized AP is determined as a function of at least one of (i) the tracking record and (ii) a calibrating record. The calibrating record may include (a) at least one of a second strength data corresponding to a strength of a calibrating beacon as transmitted from a predetermined location within the communication network and received by each of the authorized APs and a second time data correspond…
