摘要： A single chip radio transceiver includes circuitry that enables detection of radar signals to enable the radio transceiver to halt communications in overlapping communication bands to avoid interference with the radar transmitting the radar pulses. A method in a radio transceiver includes grouping a plurality of pulse data entries, generating a first list of pulse repetition intervals having pulses with a pulse width within a specified range, counting a number of most and second most common pulse interval values and determining whether a radar signal is present. Generally, the method includes determining a radar is present in one of three different ways, namely, determining whether the number of the most common pulse interval values exceeds a specified value, determining a radar signal is present with an extra pulse and finally, determining a radar is present with a missing pulse.

摘要： A single chip radio transceiver includes circuitry that enables detection of radar signals to enable the radio transceiver to halt communications in overlapping communication bands to avoid interference with the radar transmitting the radar pulses. The radio transceiver is operable to evaluate a number of most and second most common pulse interval values to determine whether a traditional radar signal is present. The radio transceiver also is operable to FM demodulate an incoming signal to determine whether a non-traditional radar signal, such as a bin-5 radar signal, is present. After. FM demodulation, the signal is averaged wherein a substantially large value is produced for non-traditional radar signals and a value approximately equal to zero is produced for a communication signal that is not FM modulated with a continuously increasing frequency signal. Gain control is used to limit incoming signal magnitude to a specified range of magnitudes.

摘要： An integrated circuit radio transceiver and associated method comprises a multi-mode device operable to support personal area network communications as well as traditional wireless local area network communications. In one embodiment, IEEE 802.11 protocol IBSS communications are used to transport Bluetooth communication data packets. In another embodiment, a direct link comprising direct packet transfers without beaconing is performed between the multi-mode device and another multi-mode device. Thus, the multi-mode device is operable to establish traditional BSS communications with an Access Point in addition to establishing peer-to-peer communications with another multi-mode device to transport the Bluetooth communications over the 802.11 IBSS communication link or over an IEEE 802.11 direct communication link.

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.
