Abstract

This paper investigated the channel link budget for Wireless Avionics Intra-Communication (WAIC) in 4.4GHz. The band 4.2~4.2GHz was allocated for the communication service among aeronautical applications in world radiocommunication conference (WRC). Wireless channels in aircraft was modelled by the combination of path loss, shadowing effect caused by obstacles, and fading caused by multipath signals. In addition, wireless channels in aircraft are categorized into 6 groups according to various locations of transmitter and receiver. We analyzed the channel link budget for the 6 channel groups in terms of maximum transmission distance and outage probability. Our analysis and intensive computer simulation results show that the propagation characteristics of group A, B, and F is superior to group C, D, E, and the propagation of group E is the most vulnerable. Also, these results can be utilized as basic reference for the channel analysis of intra-aircraft or similar environment.

본 논문에서는 4.4GHz 대역에서 항공기내 무선 통신을 위한 채널 링크 버짓을 분석하였다. 항공기내의 채널을 일반적인 경로 손실, 장애물로 인한 음영효과, 그리고 다중 경로 신호로 인한 페이딩의 조합으로 모델링하였다. 그리고, 항공기내에 존재할 수 있는 송수신기의 다양한 위치에 따라서 채널을 A~F의 6개 그룹으로 분류하고, 6개의 채널 그룹별로 최대 전송 가능 거리와 전송 오류 확률 측면에서 링크 버짓을 분석하였다. 다양한 분석과 컴퓨터 시뮬레이션 결과에 따르면, A, B, F 채널 그룹이 C, D, E 그룹 대비 우수한 전파 특성을 가지며, 그룹 E의 전파 특성이 가장 열악한 것으로 확인되었다. 이러한 결과들은 항공기내 또는 이와 유사한 환경에서의 채널 분석을 위한 기초자료로 활용 가능하다.
