摘要： Briefly, in accordance with one embodiment of the invention, a client node transmits a wakeup notification message to a supporter node when the client node is in a higher power awake mode. The supporter node may transmit data, if any, to the client node until there is no more data to be transmitted to the client node. The supporter node then transmits a done transmitting packet to the client node when the buffer memory is empty to indicate there is no more data to be transmitted. Upon receiving a done transmitting packet, the client node may enter into a lower power sleep mode until a subsequent awake event. The wakeup notification message may be transmitted by the client node at a time or interval selected to provide a power savings to the client node.
摘要翻译：简而言之，根据本发明的一个实施例，当客户端节点处于较高功率唤醒模式时，客户端节点向支持者节点发送唤醒通知消息。支持者节点可以将数据（如果有的话）发送到客户机节点，直到没有更多的数据被发送到客户机节点。然后，当缓冲存储器为空时，支持者节点将完成的发送分组发送到客户机节点，以指示不再有要发送的数据。在接收到完成的发送分组之后，客户端节点可以进入较低功率睡眠模式，直到后续的清醒事件。唤醒通知消息可以由客户端节点在选择的时间或间隔中传送以向客户端节点提供功率节省。

摘要： Two separate radio frequency networks may be operated within interference distance from one another in a way which mitigates the possibility of interference. Using received signal strength indicator data, the nature of the interference may be determined without actually demodulating the interfering signal. The timing of the interfering signal and its characteristic features may be determined. Using that information, together with the probability that any given slot will actually be occupied by an interfering transmission, a statistics package may be developed which gives an indication of the probability of a transmission from the interferer at any given time. That package may be transmitted to other nodes in the same network. When a first node wishes to transmit information to a second node, the first node may analyze the statistics package received from the second node. The first node may thereby make a determination about when to actually initiate the transmission to the second node.

摘要： Briefly, in accordance with one embodiment of the invention, an access point may preemptively broadcast an alternate channel to switch to, along with an indication of the beacon timing for the alternate channel, prior to any catastrophic interference. The access point may switch to the alternate channel in the event of interference on the original channel without attempting to broadcast the alternate channel during the interference event. A mobile user may then know in advance of the interference event which alternate channel the access point switched to and may switch to the alternate channel.

摘要： An access point in a wireless network may receive packets over a wired network. The access point may be provided with instructions from the host to determine when to awaken the host from a reduced power consumption state in response to the receipt of a packet. Thus, the access point can enforce wake packet filtering rules while the host is maintained in a reduced power consumption state. This may reduce the power consumption of the host by avoiding the unnecessary awakening of the host every time a packet of little importance arrives over the network.
