    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.

    Abstract: A search algorithm to find a globally optimal radio plan for a wireless network, including assignments of frequency and transmission power to multiple access points. Two different evaluation metrics are used in order to provide an optimal solution in a reasonable time period. Frequency searches are performed using a special rapid evaluation metric. Transmission powers are selected using a more refined metric that estimates data throughput. The search results are deterministic and execution time is also substantially deterministic.

    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. 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.

    Abstract: Methods and apparatus are disclosed for locating and disabling the switch port of a rogue wireless access point. In one embodiment, a network management device is configured to detect the presence of a rogue access point on a managed wireless network. Once detected, the management device may then instruct a special client, such as a scanning AP, to associate with the rogue access point and send a discovery packet through the rogue access point to network management device. The network management device upon receiving the discovery packet may thereby determine that the rogue access point is connected to a network managed by said network device. The network device may then utilize information contained in the discovery packet to locate the switch port to which the rogue access point is connected, and ultimately disable the switch port to which the rogue access point is connected.

    Abstract: Systems and methods for evaluating wireless network quality. A metric provided by embodiments of the present invention relies on information that is relatively easy to collect, can be very efficiently computed, and yet provides a realistic estimate of likely wireless network performance. In one implementation, the input includes path loss data and access point transmitter power level and frequency settings. A capacity indicator is computed for each client and each access point. A data rate indicator is computed for each client location. The traffic load is computed for each access point. Based on these computed indicators, a bidirectional client throughput can be computed for each client and a combined metric can be determined for the network as a whole.
