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. At the same time that all of the transceiver elements are powered on, any selected application element receives power. Thus, application elements such as address books, calendar functions, games, word processors, etc may receive power when selected. |
