Abstract

Vehicular communications extend their application areas by combining communication technologies with roads/vehicles, and one of major applications is Smart Highway project. Smart Highway is a new advanced highway system which enhances the current highway system in Korea by improving reliability, safety and convenience. In this paper, we introduce wireless access technologies for vehicular communications especially focusing on Smart Highway. We first introduce the overall communication system architecture and the basic service and communication requirements for Smart Highway. Then, we discuss wireless access technologies including L2-level hand-over scheme. In addition, the results of experimental measurements of Wireless Access in Vehicular Environments (WAVE) system are introduced.

차량통신은 통신기술과 도로/자동차기술을 융합함으로써 응용분야를 확장해왔으며, 여러 응용분야 중 중요한 한 가지가 스마트하이웨이 프로젝트이다. 스마트하이웨이는 현재의 고속도로 시스템에서 정시성, 안전성 및 편의성을 향상시킨 진보된 차세대 고속도로이다. 본 논문에서는 차량통신을 위한 무선전송기술을 스마트하이웨이에 중점을 두고 소개한다. 먼저 전제적인 통신시스템의 구조 및 기본적인 서비스/통신 요구사항에 대해 소개한 후 L2레벨 핸드오버 및 무선전송기술에 대해 논의한다. 마지막으로 WAVE시스템을 이용한 기본시험결과에 대해서도 소개한다.
