ICT기술이 차량 교통 시스템에 적용되면서 스마트한 도로 교통 시대(ITS)가 열리고 있다. 이러한 기술적 진보를 가져온 요소 중 하나는 고속으로 이동하는 차량과 인프라 간의 통신기술이다. IEEE802.11p기반의 WAVE 통신기술을 적용하여 도로교통의 다양한 안전서비스들과 운전자 편의 서비스들이 개발되고 있다. 본 논문에서는 이러한 ITS 서비스들의 품질을 보장하기 위해 필요한 link budget 분석을 수행하였다. 고속도로 환경에 적합한 경로손실 모델로 자유공간 모델과 two-ray모델을 통한 비교 분석을 통해 안정적인 통신 서비스가 가능한 셀 커버리지를 분석하였다.
