A hand held radio host includes circuitry for selectively providing power to radiating transceiver elements and non-radiating application elements according to a plurality of power modes of operation to achieve desired effects and in a way that saves power and extends battery life. In one embodiment of the invention, the hand held host operates in one of three modes. In a full power mode, any selected application element, as well as all transceiver elements, are powered on at the same time. Thus, for example, a cell phone module, a wireless personal access network module, a wireless local area network module, and one of a pager/short message service message module may all be powered on at the same time to receive corresponding messages, calls, data sessions, etc.
