    Abstract: A wireless device includes processing circuitry, a receiver section, a transmitter section, and an antenna. The processing circuitry determines a set of information signals of a RF Multiple Frequency Bands Multiple Standards (MFBMS) signal. The receiver section down-converts a portion of the RF MFBMS signal by one or more respective shift frequencies to produce a corresponding baseband/low Intermediate Frequency (BB/IF) information signal from which the processing circuitry extracts data. The transmitter section converts a respective BB/IF information signal received from the processing circuitry by a respective shift frequency to produce a corresponding RF information signal and a combiner that combines the RF information signals to form a RF MFBMS signal. The receiver section and the transmitter section include ADCs and/or DACs, respectively, that are adjustable based upon characteristics of the RF MFBMS signal, the BB/IF MFBMS signal, and/or based upon signals carried therein, e.g., modulation type, SNR requirements, etc.

    Abstract: A multiservice communication device includes a plurality of transceivers that wirelessly transceive data with a corresponding plurality of networks in accordance with a corresponding plurality of network protocols. An environmental monitoring receiver processes received RF signals over a broadband spectrum and that generates environmental data in response thereto. A processing module processes the environmental data and generates a least one control signal in response thereto, the at least one control signal for adapting at least one of the plurality of transceivers based on the environmental data. In an embodiment of the present invention, the environmental monitoring receiver can be implemented via one of the plurality of transceivers when operating in an environmental monitoring mode.
