PROBLEM TO BE SOLVED: To properly adjust the transmission strength of a radio signal in the communication terminal at a transmission side in accordance with the intensi ty of the received radio signal when the radio signal is transmitted/received between plural communication terminal. SOLUTION: When CPU 2 receives a radio signal transmitted from a communication destination through an antenna 7 in communication terminal 1 transmitting/receiving the radio signal with the prescribed communication terminal, a signal strength detection part in radio transmission/reception terminal 6 detects the signal strength at the time of reception and CPU controls the current supplied to a high frequency amplifier in the radio transmission/reception terminal 6 based on detected signal strength. Thus, transmission signal strength is adjusted. |
