摘要： Determining the location of a radio tag or client station of a wireless network, and the location of coverage holes by receiving from a plurality of wireless stations of the wireless network path loss information of the path loss of one or more location frames received at the respective wireless stations. The location frames transmitted by the radio tag or client station having a pre-defined frame structure. The radio tags and client stations use a common infrastructure for transmitting a location frame configured for radiolocation by path loss measurement. The common infrastructure includes a pre-defined protocol common for both radio tags and client stations for transmitting information for reception by the plurality of stations of the wireless network for radiolocation. The pre-defined protocol includes using the location frame having the pre-defined frame structure.

摘要： A method, an apparatus, and a software program to implement a method to detect a rogue access point of a wireless network. The method includes maintaining an AP database that includes information about managed access point (APs) and friendly APs, including the MAC address of each managed AP. The method further includes sending a scan request to one or more managed APs, including one or more of a request for the receiving managed AP to scan for beacons and probe responses and a request for the receiving managed AP to request its clients to scan for beacons and probe responses. The method further includes receiving reports from at least one of the receiving managed APs, a report including information on any beacon or probe response received that was sent by an AP. For each beacon or probe response on which information is received, the method analyzes the information received in the report about the AP that sent the beacon or probe response, the analyzing including ascertaining if the MAC address of the AP that sent the beacon or probe response matches a MAC address of an AP in the AP database to ascertain whether or not the AP is a potential rogue AP or a managed or friendly AP.

摘要： In an access point operating in a wireless local area network, a method is disclosed for assisting a radio manager to manage a radio environment without location information. By performing radio discovery to receive beacon signals from neighboring access points, an initial configuration of a radio environment is generated based on said received beacon signals. Measurements are received from a client device that performs measurements by a user walking through a desired coverage area while operating the client device and the radio configuration is adjusted based on the received measurements.
