Abstract:
In an example embodiment, there is disclosed herein, an apparatus comprising an interface and location determination logic coupled with the interface. The location determination logic receives data representative of measured signal strengths for a wireless device from a plurality of receiving devices at known locations via the interface. The location determination logic determines an estimated location based on the measured signal strengths and a first transmit power for the wireless device. The location determination logic determines a revised transmit power for the wireless device based on the measured signal strengths from the plurality of devices at known locations and the estimated location. The location determination logic determines a revised estimated location based on the measured signal strengths and the revised transmit power for the wireless device.
Abstract:
A secure localization method for wireless networks utilizes access point variable transmission power capability to transmit encoded localization signals at different power levels to a wireless device in the network. Based on the particular combination of encoded signals collected by the wireless device and reported back to a network controller, the location of the wireless device may be determined in conjunction with information contained in a location database.
Abstract:
A system and method for locating a wireless client using trusted wireless detectors is described. Sniffers may sense signal strength information and transmit the information to a database. The database may store signal strength-based location information. Information from the database may then be used to determine the location of a wireless client based on new signal strength information from one or more sniffers.

Abstract:
In an example embodiment, unauthorized wireless services and advertisements can be detected by access points via active or passive scanning. Unauthorized, or rogue, service advertisements are reported to the venue owner along with contextual information for further mitigation.
