Zusammenfassung: | Disclosed is an interior experimental apparatus of wireless communication system performance capable of improving the reliability of radio wave measurement by reducing a beam incident angle to an absorber to improve radio wave absorption performance. The experimental apparatus comprises: an electromagnetic wave reflection chamber having a horizontal cross-section polygonal structure; a base station antenna disposed in the center of the electromagnetic wave reflection chamber; a transmission device transmitting radio waves to the base station antenna in the electromagnetic wave reflection chamber; and a support stand disposed at the center of each surface of the polygon to support a wireless communication terminal as a test target and simulating shortening of a transmission distance due to propagation loss.
흡수체로의 빔 입사각을 줄여 전파 흡수성능을 좋게 함으로써 전파 측정의 신뢰성을 향상시킬 수 있는 무선통신 시스템 성능의 실내 실험장치가 개시된다. 상기 실험장치는, 수평 단면이 다각형 구조를 갖는 전자파무반사실; 상기 전자파무반사실의 중앙에 배치된 기지국 안테나; 상기 전자파무반사실의 내부에서 상기 기지국 안테나로 전파를 전송하는 송신장치; 및 상기 다각형의 각 면의 중앙에 배치되어 실험대상인 무선통신단말기를 지지하고, 전파 손실에 의한 전송 거리의 단축을 모의할 수 있는 지지 스탠드를 포함한다. |
