A mobile communication device configured to receive two or more wireless signals in at least a first frequency band and a second frequency band comprising: an antenna configured to receive over the first frequency band cellular communication signals and receive over the second frequency band at least one other signal that is not a cellular communication signal; or two or more antennas (404, 420), one of which is configured to receive, over the first frequency band, cellular communication signals, and the others of which are configured to receive, over the second frequency band, signals that are not cellular communication signals; the communication device further comprising: a mixed signal device on a single integrated circuit configured to perform analog and digital processing, and share processing between the cellular communication signals and the signals that are not cellular communication signals; characterised in that the cellular communication signal is a paging signal used during a paging mode to maintain synchronization with the cellular network, the mixed signal device being configured to demodulate the cellular communication signals and the signals that are not cellular communication signals; and the communication device comprises a digital signal processor configured to concurrently process both the demodulated paging signal and the at least one other signal, the processing resources of the processor being such that processing of the paging signal during paging mode requires only a portion of the processor's processing resources required to sustain the maximum data rate supported by the communication device. an antenna configured to receive over the first frequency band cellular communication signals and receive over the second frequency band at least one other signal that is not a cellular communication signal; or two or more antennas (404, 420), one of which is configured to receive, over the first frequency band, cellular communication signals, and the others of which are configured to receive, over the second frequency band, signals that are not cellular communication signals; the communication device further comprising: a mixed signal device on a single integrated circuit configured to perform analog and digital processing, and share processing between the cellular communication signals and the signals that are not cellular communication signals; characterised in that the cellular communication signal is a paging signal used during a paging mode to maintain synchronization with the cellular network, the mixed signal device being configured to demodulate the cellular communication signals and the signals that are not cellular communication signals; and the communication device comprises a digital signal processor configured to concurrently process both the demodulated paging signal and the at least one other signal, the processing resources of the processor being such that processing of the paging signal during paging mode requires only a portion of the processor's processing resources required to sustain the maximum data rate supported by the communication device. a mixed signal device on a single integrated circuit configured to perform analog and digital processing, and share processing between the cellular communication signals and the signals that are not cellular communication signals; characterised in that the cellular communication signal is a paging signal used during a paging mode to maintain synchronization with the cellular network, the mixed signal device being configured to demodulate the cellular communication signals and the signals that are not cellular communication signals; and the communication device comprises a digital signal processor configured to concurrently process both the demodulated paging signal and the at least one other signal, the processing resources of the processor being such that processing of the paging signal during paging mode requires only a portion of the processor's processing resources required to sustain the maximum data rate supported by the communication device.
