Abstract: Wireless medium reservation for simultaneous transmission of multiple downlink spatial streams to multiple receiver wireless stations during a multi-user transmit opportunity over a wireless medium, is provided. Such a reservation includes reserving a transmission period for simultaneously transmitting data from a transmitting station to multiple intended receiving stations on multiple downlink spatial streams over a wireless communication medium. Reserving the transmission period includes transmitting a request-to-send (RTS) frame to the multiple receiving stations, the RTS frame including a receiver address (RA) field comprising compressed addresses for the multiple receiving stations.

Abstract: Methods and systems are provided for secure switching of a roaming wireless terminal. The system includes a network having a plurality of access points for communicating with a wireless terminal. The network includes a first access point configured to couple with the wireless terminal, and a second access point configured to couple with the wireless terminal. The first access point is further configured to generate a first authentication information with the wireless terminal, and connect the wireless terminal with the network upon an authentication of the wireless terminal based on the first authentication information. The first access point is further configured to transmit the first authentication information to the second access point via the network upon the authentication of the wireless terminal. The second access point is further configured to connect the wireless terminal with the network using the first authentication information.

Abstract: A site survey device including a location sensor and a processor coupled to the location sensor. The processor acquires location information from the location sensor and determines reception data relating to a signal received from a wireless device to identify a location wherein the reception data is determined. The location sensor may include an electronic compass to produce electrical signals corresponding to a heading of a surveyor and an inertial sensor to produce electrical signals corresponding to a magnitude of a change in location. The location information may be determined as a change in location. In operation, a plurality of location information may be acquired together with corresponding reception data from a wireless infrastructure. The device may indicate each of the plurality of location information and corresponding reception data on an electronic indication of a site map.
