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： Symmetrical and asymmetrical ad-hoc, wireless networks and a method for saving power in the same may include causing a first station to determine whether a second station has a master capability to buffer data traffic for the first station. A first station requests the second station to buffer the data traffic intended for the first station for a first predetermined period. The first station enters a first power save mode, and the second station buffers the data traffic for the first station for the first predetermined period. The first station exits the first power save mode after the first predetermined period and the second station sends the buffered data traffic to the first station. Both the first and second stations may have master capabilities, or only one of the first and second stations may have a master capability.

摘要： An ad-hoc network approach for addressing ad-hoc network address assignment, name resolution, and service discovery in ad-hoc networks. The size of the ad-hoc network may be limited to a selected number of ad-hoc network stations. A first portion of the ad-hoc network address assigned to stations joining the ad-hoc network may be fixed and a second portion of the ad-hoc network address may be selected dynamically, as each new station joins the ad-hoc network. A station may generate an information element that may be included in ad-hoc network messages. An exemplary information element may include a last byte of the ad-hoc network address associated with the transmitting station, a 4-byte timestamp field which indicates a number of milliseconds since the station claimed the network address, a user-friendly name to identify the station, a universally unique identifier (UUID) for each service offered by the transmitting station, and a network-address-in-use bitmap.

摘要： A first wireless device including a control module and a transmitter. The control module is configured to estimate a first path loss between the first wireless device and a second wireless device, estimate a second path loss between the first wireless device and the second wireless device, generate an absolute value of a difference between the first path loss and the second path loss, and compare the absolute value of the difference between the first path loss and the second path loss to a predetermined threshold. The transmitter is configured to transmit a radio frequency signal at the first minimum transmit power in response to the absolute value of the difference being less than or equal to the predetermined threshold, and transmit the radio frequency signal at a second minimum transmit power in response to the absolute value being greater than the predetermined threshold.
