Abstract

본 발명은 셀룰라폰의 전파수신 지시장치에 관한 것으로서, 이는 단말기에서 기지국으로 보내지는 전파와 기지국에서 단말기로 보내어지는 전파의 경로손실이 같다는 점에 착안하여 기지국과 단말기와의 통화시, 또는 비통화시에 가장 양호한 전파의 송수신경로를 감지하고 이를 통화자에게 알려주어 그 위치로 이동시키도록 함으로써 단말기와 기지국간의 송수신 통화 실패율을 최소화시키도록 한 것이다. 이와 같은 본 발명은 안테나를 통해 수신된 고주파신호를 저잡음증폭수단을 통해 증폭하고 혼합수단을 통해 기준 국부발진 주파수와 혼합하여 얻어진 낮은 전파의 일부를 샘플링하여 전달하는 전파전달수단과, 상기 전파전달수단에서 얻어진 수신전파의 세기를 측정하는 전력측정수단과, 상기 전력측정수단에서 얻어진 현재의 수신전파의 세기와 기준치와를 비교하는 전력비교수단과, 상기 전력비교수단에서 얻어진 결과에 따라 전력의 세기를 표시하여 주는 표시수단으로 이루어짐으로써 달성된다.The present invention relates to an apparatus for indicating a radio wave reception of a cellular phone, which is focused on the fact that the path loss of the radio wave transmitted from the terminal to the base station and the radio wave transmitted from the base station to the terminal is the same. It is to minimize the transmission and reception failure rate between the terminal and the base station by detecting the best transmission and reception path of the radio wave and notify the caller to move to the location. The present invention is a radio wave transmission means for amplifying a high frequency signal received through the antenna through a low noise amplification means and a portion of the low wave obtained by mixing with a reference local oscillation frequency through a mixing means, and the radio wave transmission means Power measuring means for measuring the intensity of the received radio wave obtained by the power source; power comparing means for comparing the intensity of the current received radio wave obtained from the power measuring means with a reference value; This is accomplished by being made up of display means for displaying.
