摘要： A method is presented for adapting the packet size for VoIP communications, determined on-the-fly by the total network delay inherent at the time of packet transmission. If network delays are small relative to the maximum permissible latency for VoIP communications, the payload size per packet may be increased to maximize efficiency for the transmitted call. Alternatively, if network delays are large, the payload size per packet may be decreased in order to assure that the perceived quality of the transmitted call is acceptable.

摘要： If a handoff by a mobile station currently associated with a particular access point is probable, then the particular access point sends an activation alert to one or more other access points. An access point receiving the activation alert that is in a low-power state enters a higher-power state. An access point receiving the activation alert that is in a higher-power state, remains in that higher-power state.

摘要： Methods and apparatus for controlling a wireless access point (AP) (e.g. a battery-powered wireless AP) for reduced power consumption are provided. In one illustrative example, the AP is adapted to provide communication access for end stations in one or more activated service intervals of each superframe. During operation, the AP changes the number of activated service intervals that are available to end stations for the communication access, as well as the durations of their active subinterval durations, in accordance with a change in traffic requirements. The AP regularly broadcasts data which indicates the activated service intervals that are made available to the mobile devices. A wireless transceiver of the AP is enabled during each activated service interval made available to the mobile devices, but the AP is placed in a power conservation mode during each deactivated service interval provided in between the activated service intervals. The AP may also be placed in the power conservation mode during inactive subintervals of each activated service interval.

摘要： A mesh node of an infrastructure wireless local area network ‘WLAN’ is coupled to a battery which is coupled to a device that is able to harness energy from a source of renewable energy. Energy management of the mesh node includes conducting simulations of a system comprising the mesh node, the device, and the battery in its current state of charge, determining an admissible load for the mesh node from the simulations, and withholding communication services by the mesh node for one or more periods of time a cumulative duration of which is related to power consumption of the mesh node when handling the admissible load. The simulations involve meteorological data related to the source of renewable energy in the vicinity of the mesh node.

摘要： A wireless access point supports data rates and advertises an indication of a minimum data rate for advertisement. Those of the supported data rates that are less than the minimum data rate for advertisement are reserved for limited use. A mobile station that requests to communicate with the wireless access point at one of the one or more supported data rates that are reserved for limited use is informed by the wireless access point how much time communications with the wireless access point at one or more of the one or more supported data rates reserved for limited use will be permitted.

摘要： A wireless local area network includes multiple access points with overlapping coverage, and modes of different power consumption are available to the access points. It is assessed whether the traffic load of the network may be adequately supported using fewer access points in an active mode. If so, the traffic load is redistributed from certain active access points among the remaining access points in the active mode. The certain access points are switched into a mode of lower power consumption than the active mode. Similarly, it is assessed whether the traffic load of the network is adequately supported by the current number of access points in an active mode. If not, certain access points which are in a mode of lower power consumption are switched to the active mode. The traffic load is redistributed among the access points in the active mode including the certain access points.
摘要翻译： 无线局域网包括具有重叠覆盖的多个接入点，并且接入点可以使用不同功耗的模式。 评估是否可以在活动模式下使用更少的接入点来充分支持网络的流量负载。 如果是这样，则在活动模式下的剩余接入点中的某些活动接入点重新分配流量负载。 某些接入点切换到比活动模式更低的功耗模式。 类似地，评估网络的业务负载是否由活动模式中的当前接入点数量充分支持。 如果不是，则处于较低功耗模式的某些接入点被切换到活动模式。 流量负载在包括某些接入点的活动模式的接入点之间重新分配。

摘要： A mobile station is assisted to perform a handoff from a current access point in a current extended service set (ESS) to a new access point in a target ESS. A HandOver Mediator, possibly in conjunction with a handover server, performs an authentication process and an association process with an access point in the target ESS while masquerading as the mobile station. Parameters resulting from the authentication process and the association process are then passed to the mobile station and the mobile station can perform a handoff to the new access point.
