Abstract

본 발명은 무선전화기의 송신출력 조절방법 및 장치에 관한 것이다.The present invention relates to a method and an apparatus for adjusting the transmission power of a wireless telephone.

종래의 무선전화기 및 동시통화 무전기는 안테나를 통해 수신된 고주파 신호를 증폭, 주파수 변환 복조함과 아울러 수신 전계강도를 발생하는데 이와 같은 수신 전계강도가 약할 경우 변조된 고주파신호를 항상 일정하게 증폭하여 안테나를 통해 송출하게 되는데, 이와 같이 통화거리와 관계없이 근거리 사용시에도 고주파신호를 항상 일정하게 증폭하여 전송하므로서, 밧데리의 소모전류가 많고 타무선 전화기와의 간섭 영향이 많은 문제점이 있었다.Conventional radiotelephones and simultaneous talk radios amplify and frequency demodulate high-frequency signals received through antennas and generate received field strengths.When such received field strengths are weak, modulated high-frequency signals are constantly amplified. In this way, regardless of the distance, regardless of the distance, the high-frequency signal is always amplified and transmitted constantly, even when using a short distance, there is a problem that the consumption current of the battery has a lot and the interference effect with other wireless telephones.

따라서 본 발명은 상기한 종래기술의 문제점을 개선코자 하여 무선전화기의 고정장치 수신단에서 휴대장치의 출력 레벨을 측정한 데이타를 휴대장치로 송출하면 휴대장치에서 이를 분석하여 휴대장치의 출력을 조절하도록 한 것이다.Therefore, the present invention is to improve the above-mentioned problems of the prior art to transmit the data measured the output level of the portable device to the portable device at the fixed device receiving end of the radiotelephone device to analyze the output to adjust the output of the portable device will be.
