Abstract

In recent years, a variety of ITS services are available such as driving information, road conditions, V2X messages as well as navigation and traffic jams notification. The development of ITS services is accelerating by V2X communication technologies for high-speed vehicles. In this paper, WAVE communication devices based on the IEEE802.11p standard is introduced as a solution of V2X communication technologies. The H/W and S/W structures of the WAVE communication device and the characteristics of RF/antenna are described. The performance is evaluated in the test road by measuring throughput, PER and latency. The implemented WAVE communication device has 6~7 Mbps throughput with 10% PER at 1km coverage. The packet latency is less than 3ms for the whole test road. It is shown that the implemented WAVE technology is satisfactory to provide ITS services and Internet video-streaming services.

최근에는 차량용 센서와 통신 기술의 발달로 길안내와 교통체증 알림 서비스뿐만 아니라 주변 차량의 주행 정보, 도로 상태 정보, 차량 간 긴급 메시지 전달 등과 같은 다양한 ITS 서비스가 가능해졌다. ITS 서비스의 발전은 고속 주행용 차량을 위한 V2X 통신 기술이 소개되면서 가속화 되고 있다. 본 논문에서는 V2X 통신기술 중에서 IEEE802.11p 규격을 기반으로 개발한 WAVE 통신장치를 소개한다. WAVE 기술로 구현된 기지국 및 차량 통신장치에 대한 구조 및 특징 그리고 각 통신장치에 사용된 RF/안테나의 특성에 대해서도 설명하였다. 개발한 WAVE 통신장치의 성능 평가를 위해 시험차량에 설치된 통신장치와 시험 도로에 설치된 기지국 통신장치간의 데이터 전송량과 PER 그리고 지연시간 등을 실제시험도로에서 측정하였다. WAVE 통신장치는 전반적으로 6~7Mbps의 데이터 전송량을 가지며 1km 통신영역에서 10% 내외의 PER를 나타내었다. 그리고 모든 구간에서 3ms이내의 패킷 지연시간을 만족하였다. 측정된 WAVE 성능은 ITS 서비스에 충분한 성능이며 인터넷 동영상 서비스도 가능함을 실제 시연을 통해서 입증하였다.
