Abstract: 본 발명은 단순한 페이더(fader)가능만을 가지고 있는 기존의 이동통신용 시뮬레이터와는 다러리, 본 장치를 이용하여 실제로 공중으로 전파를 발사하지 않고 양 방향 통시상태에서 기지국과 이동국간의 다양한 기능을 시뮬레이션 할 수 있는 것으로, 본 발명은 구성은 순방향 링크용과 역방향 링크용으로 구성되어 있으며 기지국과 이동국간의 full duplex(양방향)통신이 가능하도록 감쇠기와 전력 분배기(spoitter)를 이용한 루트와 페이더그리고 이를 전기적으로 제어하는 컴퓨터 드으로 구성되어 있으며, 본 장치를 이용함으로써 실제로 전파를 발사하지 않고도 이동통신에서의 전파 환경을 완벽히 구현함으로서 이동통신 시스템 분석을 위항 상단한 필드 시험의 시간을 줄일 수 있으며 그 구성 자체도 간단한 부품들로 구성함으로써 가격면에서도 값싸게 성할 수 있다.
