  • Patent number: 7385945
    Abstract: 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 the 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.

  • Publication number: 20080076430
    Abstract: A method to facilitate handover includes detecting that a mobile unit resides within at least one predetermined zone where a handover event from a first radio technology to a second radio technology may need to occur, the second radio technology being different from the first radio technology.

  • Publication number: 20080032727
    Abstract: Methods, apparatuses and systems directed to identifying coverage holes in wireless networks. According to one implementation of the present invention, the wireless network infrastructure analyzes signal strength data to detect potential coverage holes associated with one or more wireless clients and validates the potential coverage holes based on observed coverage data.

  • Patent number: 7293088
    Abstract: 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.

  • Patent number: 7286515
    Abstract: 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.
