  • Patent number: 8437263
    Abstract: An access point in a wireless network is traced by sending an internet protocol (IP) packet from a detector to the access point through the wireless network. The detector and the access point are connected through a private wired network. The IP packet is sent with the source IP address field and the destination IP address of the IP packet set to the wireless IP address and wired IP address, respectively, of the detector. The IP packet is routed back to the detector through a switch in the private wired network. When the IP packet is received at the detector, a source IP address, which corresponds to the port on the switch used to send the IP packet, is determined from the received IP packet.

  • Patent number: 7836166
    Abstract: The service set identification (SSID) of an access point (AP) in a wireless local area network (WLAN), where the AP suppresses its SSID in beacon frames broadcasted by the AP, is determined. At a detector located in the WLAN, a probe request broadcasted by a station through the WLAN is received. At the detector, a probe response sent by the AP to the station through the WLAN in response to the probe request broadcasted by the station is received. At the detector, the SSID of the AP is obtained from the received probe response.

  • Patent number: 7711809
    Abstract: In a wireless local area network a probe request frame is transmitted over the wireless local area network by a station. The probe request frame is received at a detector in the wireless local area network. The received probe request frame is analyzed to determine if the station that transmitted the probe request frame is an unauthorized station.

  • Patent number: 7702775
    Abstract: A wireless local area network (WLAN) is monitored by receiving transmissions exchanged between one or more stations and an access point (AP) in the WLAN using a detector located in the WLAN. A database is compiled based on the received transmissions. The received transmissions are analyzed to determine the state of a station. The compiled database and the determined state of the station are used to diagnose connectivity problems of the station.

  • Patent number: 7613139
    Abstract: In a wireless local area network, an access point failing to adhere to proper power management protocol is detected by analyzing a beacon frame sent by the access point to determine if a traffic information map (TIM) in the beacon frame is zero. A frame sent by a station is analyzed to determine if the station is in a power save mode. A data frame sent by the access point is analyzed to determine if the data frame is destined for the station. An improper power management protocol condition of the access point is determined based on the foregoing analysis.

  • Patent number: 7539146
    Abstract: In a wireless local area network, beacon frames are transmitted over the wireless local area network by one or more access points. The beacon frames are received at a detector in the wireless local area network. The received beacon frames are analyzed at the detector to detect a counterfeit access point in the wireless local area network.

  • Patent number: 7385948
    Abstract: In a wireless local area network, transmissions exchanged between a station and an access point is received using a detector located adjacent to the station. The received transmissions are analyzed to determine the state of the station, where the state of the station indicates whether the station has authenticated and/or associated with the access point in the wireless local area network.

  • Patent number: 7292562
    Abstract: A method and system for measuring the throughput of transmissions over a wireless local area network having a station and an access point. The station can send messages to the access point during a test period, where the messages can be sent as data frames. The access point can receive messages sent from the station during the test period. For messages received by the access point, the access point can send acknowledgements to the station, where the acknowledgements can be sent as control frames. The station can receive acknowledgements from the access point for messages received by the access point. The station can determine a throughput from the station to the access point for the test period based on the acknowledgements received at the station from the access point during the test period.

  • Publication number: 20070036091
    Abstract: A method and system for detecting a hidden node in a wireless local area network having a first station, a second station, and an access point. The first station can send a message, where the message can be sent as a data frame. After receiving the message, the access point can send the message to the second station. The second station can receive the message from the access point. In response to receiving the message, the second station can send an acknowledgement to the access point, where the acknowledgement can be sent as a control frame. The first station can monitor for the acknowledgement sent from the second station to the access point.
