Abstract

This article studied the radio station inspection method, which utilizes the 8T8R combiner to reduce 5G radio station inspection measurement times. It is a common that 5G radio station inspections measure RF (Radio Frequency) output signals, which correspond to the number of arrayed antennas individually. However, this study suggested a way to save the time spent on existing methods, by comparing measurement values of individual channels and 8T8R. As a result, it is confirmed that when the 8T8R combiner is used, not only the resulting value of radio station inspections was accurate, but also the measurement time being shortened by up to 8 times compared to existing method.

본 논문에서는 5G 무선국 검사에 있어, 측정 시간 단축을 위한 8T8R 콤바이너를 활용한 무선국 검사 방법에 관하여 연구하였다. 5G 무선국 검사는 배열된 안테나 수에 대응하는 RF(: Radio Frequency) 출력 신호를 개별적으로 측정해야 한다. 하지만, 본 연구에서는 개별 채널 측정 결과와 8T8R을 이용한 측정값 비교를 통해 기존 방식을 시간적으로 단축할 수 있는 5G 무선국 검사 방법을 제시하였다. 연구 결과 8T8R 콤바이너를 이용하는 경우, 정확한 무선국 검사를 수행할 수 있을 뿐만 아니라, 기존방식의 소요 시간을 1/8으로 줄일 수 있었다.
