摘要： A mobile wireless device adapts roaming parameters used to determine searching for and switching among access points. The roaming parameters are adjusted based on a wireless network characterization for access points that includes a detected wireless network type. In an embodiment, the wireless network type is characterized by a service set identifier and a number of unique basic service set identifiers associated with the service set identifier per radio frequency band. Roaming parameters include a scan threshold, a roam threshold and a time interval between successive scans.

摘要： A network device including a transceiver and a control module. The transceiver is configured to detect beacons or probe responses transmitted between stations in a network, wherein each of the stations is separate from other ones of the stations, and a first one of the stations includes the network device. The control module is configured to (i) determine a number of active conversations in the network based on the beacons or probe responses, (ii) adjust a length of a window based on the number of active conversations, and (iii) transition between power modes based on the length of the window. During the window, the control module is configured to transmit a frame via the transceiver, and wherein the frame indicates the network device has a packet to transmit to a second one of the stations.

摘要： Techniques for establishing a dynamic ad-hoc wireless network are disclosed. A node transitions between wake and sleep modes during periods defined as beacon intervals. Before a network connection is established and while it is awake, the node transmits network connection request and also listens for network activity. If a beacon or response message is not detected while the node is listening, the node enters sleep mode and thereby conserves power. The node optionally changes the duration of its detection period and/or the time at which it listens for network activity relative to the start of each beacon interval. Information elements are optionally included with transmitted beacons or response messages.

摘要： A protocol governing the operation of an ad-hoc WLAN enables each device in the WLAN to be configured as a registrar and/or an enrollee. Accordingly, each device is configurable to support both the registrar as well as enrollee modes of operations. In response to a time-driven user action, the device may be configured to enter into a registrar mode or an enrollee mode. While in the registrar mode, the device enters into an aggressive beaconing phase by setting its beacon contention window to a relatively very small value. The aggressive beaconing increases the probability of the discovery of the registrar by the enrollees. Optionally the device may prompt the user to select between a registrar and an enrollee mode of operation by displaying the option on an LCD panel.

摘要： In response to determining that a Bluetooth inquiry phase or a Bluetooth paging phase is beginning, a power save (PS) mode signal is sent from a first device to a second device via a wireless local area network (WLAN) communication link, wherein the PS mode signal indicates that the first device is in a WLAN PS mode. A PS poll signal is sent from the first device to the second device via the WLAN communication link in a gap between Bluetooth inquiry phase message transmissions during the Bluetooth inquiry phase or between Bluetooth paging phase message transmissions during the Bluetooth paging phase.

摘要： Methods and systems for providing location-aware WiFi access for a portable device include determining an initial location of the portable device and transmitting the initial location to a WiFi location provider, wherein the WiFi location provider comprises locations and WiFi parameters for a plurality of WiFi access points, wherein each WiFi access point has a corresponding wireless range. The locations and the WiFi parameters for a set of WiFi access points are then received from the WiFi location provider, wherein the set of WiFi access points are within a radius of the initial location of the portable device. At least one WiFi access point in the set of WiFi access points is scanned for that contains the portable device within its wireless range. The portable device then connects to the at least one WiFi access point, thereby forming a WiFi connection.
