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.
