In FIG. 1, reference numerals 100 and 200 denote radio devices that are in a one-to-one opposite talk with each other, and each includes a transmission / reception unit 11, a reception electric field detection unit 12 that detects electric field strength of a received radio wave, and a detected reception electric field intensity. And a transmission output control unit 13 that controls the transmission output level in accordance with the above. a is the first radio wave transmitted from the radio device 100 to the radio device 200, and b is the radio wave from the radio device 200 after the radio device 200 detects the level of the radio wave a and sets the transmission output to the required minimum level. This is a radio wave transmitted to the machine 100. Further, c is a radio wave which is transmitted to the radio device 200 again by the radio device 100 which has received the radio wave b, sets the transmission output to the necessary minimum according to the detection level of the radio wave b.

In the above-described embodiment, when the wireless device 100 maximizes the set output and sends out the radio wave a from the transmission / reception unit 11, the wireless device 200 detects the reception level by the reception electric field detection unit 12 and transmits it to the wireless device 100. The output for control is switched to the minimum required level by the transmission output control unit 13 and the radio wave b is transmitted. On the other hand, the radio device 100 receives the radio wave b received from the radio device 200 when transmitting again to the radio device 200.
The electric field intensity is detected by the reception electric field detection unit 12, and the transmission output control unit 13 switches to the minimum required output level according to the intensity and sends the radio wave c. Hereinafter, between the wireless devices 100 and 200, the call is always performed while the transmission output level is controlled.
