초록

실내 환경에서 송수신기의 위치 변화에 따른 전파 전달 특성을 시뮬레이션을 통하여 예측하고, 경로손실 측정을 통하여 얻어진 결과를 예측결과와 비교하고 분석하였다. 경로손실 측정 환경으로는 대회의실을 선택하였으며, 또한 실내 장식물 및 비품이 없는 전시실을 선택하여 두 환경의 전파 전달 특성을 비교하였다. 각 실내 환경에서 송신기의 위치는 전방 벽면 중앙과 측면 벽면 중앙에 위치하는 두 가지 경우를 선택하였고, 수신기의 위치는 실내 공간의 중심선과 측면 벽을 따라 움직이며 수신 전력을 측정하였다. 각각의 송수신기 위치변화에 대하여 3GHz와 6GHz의 수신 전력을 측정하고 시뮬레이션 예측 결과와 비교하였다. 송신기의 위치 및 주파수 대역 변화에 따라 각 수신점에서 수신 전력의 변화를 분석하였다.

The radio wave propagation characteristics of the transmitter and receiver position change in the indoor environment were predicted through simulation, then the results obtained through the transmission loss measurement were compared and analyzed with the simulation results. The conference room was chosen as the environment for measuring transmission loss, and the radio transmission characteristics of the two environments were compared by selecting the exhibition hall without interior decorations and fixtures. In each indoor environment, the position of the transmitter chose two cases. One located in the center of the front wall and the other in the center of the side wall, and the position of the receiver moved along the centerline of the conference room and the side wall, measuring the receiving power. For each change in transmitter-receiver position, received power of 3GHz and 6GHz band were measured and compared with the simulation forecast results. The changes in received power at each receiving point were analyzed according to the location of the transmitter and the frequency band variation.
