摘要： A method and apparatus for dynamic frequency selection in a wireless communication system or network includes processing that begins when an access point determines interference on a wireless channel that is being used by the access point. When the interference exceeds an interference threshold, the access point provides a request packet to affiliated stations being serviced by the access point for channel spectrum information. The processing continues as the affiliated stations generate the channel spectrum information regarding each of the wireless channels in the wireless communication network. The processing proceeds then as the affiliated stations provide the channel spectrum information to the access point via the current wireless channel. The access point interprets the channel spectrum information to determine a desired wireless channel of the plurality of wireless channels within the wireless communication network. The access point then provides a selection packet to the affiliated stations via the current wireless channel to indicate that the access point will begin using the desired wireless channel at a particular future time.

摘要： A wireless local area network (WLAN) transmitter includes a baseband processing module and a plurality of radio frequency (RF) transmitters. The processing module selects one of a plurality of modes of operation based on a mode selection signal. The processing module determines a number of transmit streams based on the mode selection signal. The processing of the data further continues by converting encoded data into streams of symbols in accordance with the number of transmit streams and the mode selection signal. A number of the plurality of RF transmitters are enabled based on the mode selection signal to convert a corresponding one of the streams of symbols into a corresponding RF signal such that a corresponding number of RF signals is produced.

摘要： Protocol adaptation layer for wireless communications. Communication devices that include one or more radio modules operable in accordance with multiple communication protocols establish communications using one communication protocol and then switch to another communication protocol. This switching to another communication protocol may be performed based on a variety of factors including effectuating communications of higher throughput, supporting uni-directional communications vs. bi-directional communications, or any other desired factor. In some embodiments, various communication devices include two radio modules that are each implemented to operate in accordance with one particular communication protocol. Alternatively, a multi-protocol capable radio module may support and operate in accordance with more than one communication protocol. Examples of possible communication protocols include those compliant with Bluetooth, IEEE 802.11, and/or 802.15.3c.

摘要： A first device wirelessly transmits and/or receives swept 60 GHz beacon signals to and/or from other devices. Beacon signals indicate angle of reception and/or relative direction with respect to other devices. Knowing reception angle and/or relative direction enables beamforming of adaptive and/or steered antennas for communication. 60 GHz beacons are swept over one or more angles. Identity information, configuration information, timing information and/or spatial information are communicated via 60 GHz beacons. Control and/or coordination information are transmitted and/or received. Reception angle, relative direction and/or distance between devices are determined based on 60 GHz beacons. Adaptive and/or steered antennas used for communication are initialized and/or undergo beamforming for 60 GHz, based on the angle, direction and/or distance between devices. Devices are mobile and/or stationary. Devices comprise mobile stations, base stations, wireless phones, access points, set-top-boxes, computers, game consoles, video servers, video recorders, video playback devices, residential gateways and internet browsing devices.

摘要： A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna, generating a carrier detect field. The method continues by, for a first grouping of the transmit antennas, generating a first guard interval, and at least one channel sounding field. Continuing, the method applies cyclical shift prior to transmission via the first grouping of the transmit antennas. When the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas. For the another grouping of the transmit antennas, generating at least one other channel sounding field. The method proceeds by generating the first guard interval prior to the at least one other channel sounding field, and applying another cyclical shift prior to transmission via the another grouping of the transmit antennas.
