Abstract
Abstract The present invention provides a radio communication apparatus capable of automatically setting a frequency band, a transmission power and the like in accordance with radio wave specifications of an area where it is used. A positional information detecting section (31) receives a radio wave from a GPS satellite through an antenna (33) and inputs the radio wave to a GPS receiving section (34). The GPS receiving section (34) despreads and demodulates the spectrum-spread signal transmitted from the GPS satellite, and transmits the demodulated signal to a positioning section (35). The positioning section (35) extracts the information about a current position where the radio communication apparatus from the demodulated signal, and outputs the information to a CPU (37) of a specification controlling section (32) as information about a position where the radio communication apparatus is to be used. In accordance with the positional information transmitted from the positioning section (35), the CPU (37) makes access to a memory (36), reads radio wave specifications corresponding to the area from the memory (36), controls oscillation frequencies of oscillator (23, 29) and controls gains of amplifiers (24, 27) to control the power.
