Abstract

Vehicular communications can be applied for transmission of various safety messages or Intelligent Transportation Systems(ITS) applications by combining vehicle/road technology with Information and Communication Technology(ICT). In this paper, we represent measurement results of radio characteristics of vehicular communications using IEEE 802.11p based system in urban environments. Radio characteristics are based on the packet error rate (PER) and received spectrum mask. Using measurement results, we discuss implementation issues of vehicular communication systems for supporting reliable services.

차량통신시스템은 차량/도로기술과 정보통신기술을 접목하여 다양한 안전메시지를 전송하거나 지능형 교통시스템에 적용이 가능하다. 본 논문에서는 IEEE 802.11p를 기반으로 한 차량통신시스템을 소개하고 이 시스템의 전파특성을 도심환경에서 측정한 결과를 보인다. 전파특성은 패킷오류율과 수신스펙트럼을 이용하여 측정한다. 이 결과를 바탕으로 하여 실제 서비스 적용에 있어서 필요한 구현 이슈에 대해 논의한다.
