ABSTRACT:
A pocket transceiver can be, for example a portable wireless telephone apparatus small enough to be put into a pocket of a user. The apparatus operates at a low power level. The pocket transceiver as an independent unit only handles signals at a low power level and is suitable for communication over close range. The pocket transceiver can also be used as a telephone apparatus for communication over long range, such as a mobile transceiver in a vehicle, by being connected to an adapter, which includes a power amplifier and a power controller for selecting an output power level out of multiple levels in response to an instruction from a transmitting-receiving unit of the pocket transceiver.
