    • 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.
    • 无线设备包括处理电路,接收机部分,发射机部分和天线。 处理电路确定RF多频带多标准(MFBMS)信号的一组信息信号。 接收器部分将RF MFBMS信号的一部分下变频一个或多个相应的移位频率,以产生相应的基带/低中频(BB / IF)信息信号,处理电路从该信号信号中提取数据。 发射机部分将从处理电路接收到的相应BB / IF信息信号转换相应的移位频率,以产生对应的RF信息信号和组合RF信号信号以形成RF MFBMS信号的组合器。 接收机部分和发射机部分分别包括基于RF MFBMS信号,BB / IF MFBMS信号的特性和/或基于其中携带的信号可调节的ADC和/或DAC,例如调制类型,SNR 要求等

    • A management unit allocates network resources multiservice communication devices capable of communicating via a plurality of networks. The management unit includes a communication device interface for facilitating a bidirectional data communication with the multiservice communication devices via a wireless control channel, the bidirectional data communication including outbound control data sent to multiservice communication devices and inbound control data received from at multiservice communication devices. The wireless control channel is separate from the communication between multiservice communication devices and the networks. A network interface receives network resource data from the networks. A management processing unit generates the outbound control data in response. The management processing unit facilities the handoff of a real-time service accessed by the multiservice communication devices via a first network to a second network.
