초록

실내 로비 환경에서 다중 경로에서 6, 10, 17 GHz 주파수 대역의 전파 특성을 분석하였다. 가시선(Line-of-sight, LOS) 및 비가시선(Non-line-of-sight, NLOS) 경로는 송신 안테나 위치에서 수신 안테나 위치까지 2-16 m (0.5 m 간격) 거리에서 측정되었다. 기본 전송 손실은 경로에 해당하는 FI(Floating intercept) 경로 손실 모델을 사용하여 세 가지 매개변수를 비교하였다. RMS(Root mean square) 지연 확산은 측정 결과를 누적 확률 10, 50, 90%로 비교하였다. 기둥의 존재와 특이한 로비 구조로 인해 측정된 모든 주파수에서 전파 손실과 전파 지연이 발생하였다. 이에 실내 로비 환경에 대한 측정 시나리오와 표준 측정 데이터 제공을 제안하였다. 이를 통해 다양한 구조의 실내 로비 환경에서 5G 및 밀리미터파 대역의 전파 특성에 대한 연구에 기여할 것이다.

The radio propagation characteristics of the 6, 10, and 17 GHz frequency bands in multiple paths in an indoor lobby environment were analyzed. The line-of-sight (LOS) and non-LOS (NLOS) paths were measured from a distance of 2-16 m (0.5 m intervals) from the transmitting to the receiving antenna positions. For basic transmission losses, three parameters were compared using the floating intercept path loss model corresponding to the path. For a root mean square delay spread, the measurement results were compared for cumulative probabilities of 10, 50, and 90%. Propagation loss and propagation delay occurred in all measured frequencies owing to the existence of pillars and an unusual lobby structure. Thus, a measurement scenario for an indoor lobby environment and the provision of standard measurement data was proposed. The results may facilitate research on the radio propagation characteristics of 5G and millimeter-wave bands in indoor lobby environments with various structures.
