Abstract

A multi-band communication device configured with a mobile communication device for voice or data communication over a cellular, satellite or other communication network and configured with an auxiliary communication system configured to receive and/or transmit an auxiliary communication signal. The mobile communication device and auxiliary communication system are integrated into the same components within the multi-band communication device thereby allowing the components to share the processing tasks associated with each communication device within the multi-band communication device. The auxiliary communication device may be configured to operate during standby mode of the mobile communication device, such as during reception of a paging signal. The auxiliary communication device may comprise, but is not limited to, AM or FM radio, personal communication devices such as FRS, GMRS, or weather band radio.

Claims

1. A multi-band communication device comprising:

a first antenna configured to receive a first signal comprising a mobile communication device signal in a first frequency band;

a second antenna configured to receive at least a second signal in a second frequency band;

a mixed signal device comprising;

a first radio frequency device connected to the first antenna and configured to;

transmit and receive a mobile communication device signal;

convert the first signal to a first baseband signal;

convert the first baseband signal to a digital format;

a second radio frequency device configured to;

receive the second signal radio frequency signal;

convert the second signal to a second baseband signal;

convert the second baseband signal to a digital format;

wherein the first radio frequency device and the second radio frequency device are integrated into the same integrated circuit and are capable of concurrently outputting the digital versions of the first baseband signal and the second baseband signal;

a digital signal processor configured to concurrently receive and concurrently process the digital versions of the first baseband signal and the second baseband signal to thereby create one or more processed signals, which may be in analog or digital format;

a user interface configured to;

control at least one aspect of operation of the first radio frequency device and the second radio frequency device; and

receive at least one processed signal and provide the at least one processed signal to a user.

2. The device of claim 1, further comprising one or more digital to analog converters configured to convert the processed signal, if in digital format, to an analog signal.

3. The device of claim 1, wherein the second signal is selected from the group of signals consisting of an FM signal, an FRS signal, and a GMRS signal.

4. The device of claim 1, wherein the first baseband signal may comprise a paging signal or an active communication signal.

5. The device of claim 4, wherein the digital signal processor is configured to concurrently process the paging signal and the second baseband signal or process the active communication signal.

6. The device of claim 1, further comprising a memory integrated with or connected to the digital signal processor, the memory configured to store machine readable code capable of processing the first baseband signal and the second baseband signal.
