    摘要: A wireless station prepares to roam by pre-authenticating itself with a neighboring access point. The wireless station sends a rekey request, which can include an incremented rekey number. The wireless station receives a rekey response. The rekey response can include the incremented rekey number. Because the wireless station is pre-authenticated, after it roams it only needs to perform a two-way handshake with a new access point to establish secure communications with the new access point. The two-way handshake starts by the wireless station sending a reassociation request to the neighboring access point, the reassociation request comprising the incremented rekey number established during pre-authentication. The wireless station receives a reassociation response from the neighboring access point. To protect against replay attacks, the neighboring access point can verify the rekey number sent in the reassociation request matches the rekey number sent in the rekey response.

    摘要: A proxy server that is inserted between a plurality of network access servers, typically an access points, and an authentication server. When an original authentication request is received by a network access server, the network access server forwards the request to the proxy server which forwards the request to an authentication server. The authentication server then sends the session information to the proxy server which stores the keying material as a dynamic credentials. When the client re-authenticates with one of the plurality of access servers, the re-authentication request is handled by the proxy server using the dynamic credentials. The proxy server may re-authenticate the client using a different method than the method that was originally used. For example, the original authentication may be by Extensible Authentication Protocol—Transport Layer Security (EAP-TLS) and subsequent re-authentications may use Wi-Fi Protected Access (WPA).

    摘要: A system for automatically selecting communication frequencies for wireless communication devices (e.g., base unit, access point, and controller) being added to an existing wireless network. The operating frequencies, evaluated signal strength, and loads are used in determining the most suitable operating frequency. This automatic selection process eliminates the problems inherent in manual frequency selection.

    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 dynamic packet consolidation algorithm for a wireless transmission regime. At least first and second packets of a plurality of packets are sampled. The respective throughput times of each first and second packet are then calculated. The first and second packets are consolidated into a third packet if the sum of the corresponding throughput times exceeds a predetermined limit.
