Abstract

본 발명은 셀룰라폰의 출력신호 조절장치 및 방법에 관한 것으로 기지국측으로부터 수신되는 고주파신호(RF)인 수신전계강도신호(RSSI)를 주파수 범위에 따라 8단계로 분리한 후 설정된 기준신호값과 비교하여 기지국측으로의 송신 출력신호 레벨이 자동조절되도록 하여 전계효율을 최대화시킴과 동시에 배터리의 사용시간을 연장시킨 것이다.The present invention relates to an apparatus and method for controlling an output signal of a cellular phone. The received field strength signal (RSSI), which is a high frequency signal (RF) received from a base station, is divided into eight levels according to a frequency range, and then compared with a reference signal value. Therefore, the transmission output signal level to the base station is automatically adjusted to maximize the field efficiency and extend the battery usage time.
