摘要： Disclosed are a system and method for permitting communication between subscribers in a wireless network and devices coupled to one or more wired communication networks. A transceiving circuit transmits data to or receives data from one or more subscribers through a wireless transmission medium. A first data link control (DLC) circuit is adapted to transmit data between the transceiveing circuit and one or more devices coupled to a first wired communication network. A second DLC circuit is adapted to transmit data between the transceiving circuit and one or more devices coupled to a second wired communication network.

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： 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： A method, apparatus and system for transmitting a data link descriptor or MAP signal describing sub-burst transmissions having a common number of resource units allocated thereto. The MAP signal may include the length of the common number of resource units allocated thereto and the modulation and coding schemes to be used thereby. A method, apparatus and system for transmitting an ordered MAP signal sequence describing a series of transmissions each having a number of resource units allocated thereto. A first plurality of locations in the ordered sequence may describe lengths of resource units. A second plurality of locations in the ordered sequence may describe numbers of transmissions having the lengths described in one of the first plurality of locations. A third plurality of locations in the ordered sequence may describe a number of transmissions using one of a plurality of modulation and coding schemes. Other embodiments are described and claimed.

摘要： A way of managing bandwidth in a network supporting variable bit rate is provided. An apparatus is provided that comprises an interface to transmit data to a receiving device. The apparatus comprises a controller that is communicatively coupled to the interface, the controller to detect a bit rate change event and transmit a first portion of the data using reserved bandwidth and a second portion of the data using unreserved bandwidth in response to detecting the bit rate change event.

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.
