초록

최근 자동차 시장은 기존의 기계 위주의 기술에서 차량 정보화 및 전자화 기술로 빠르게 패러다임 변화가 이루어지고 있다. 특히, 텔레매틱스 분야는 자동차 제조사 및 이동통신 업체 간의 긴밀한 협조체제를 구축하여 차량 정보화 서비스를 위한 기술 개발을 가속화하고 있다. 그러나 텔레매틱스 서비스는 기지국과 차량, 차량 대 차량 간에 무선통신에 의해 정보교환이 이루어지고 있으므로 전파 간섭에 의한 서비스 품질의 저하를 피할 수 없다. 이에 본 논문에서는 무선통신기반의 차량 네트워크 환경에서 차량과 무선 통신 상호간 간섭을 분석할 수 있는 장비를 설계 구현하고, 시뮬레이션과 실제 차량의 실측실험을 통하여 차량 내 외부에 발생하는 간섭을 감소시켜 통신 품질을 높일 수 있는 방법을 제시한다.

Recently, there has been a fast paradigm shift in the automotive market from the traditional machine-oriented technology into the technology for vehicle informatics and electronics. In particular, telematics market is accelerating the development of technologies for vehicle informatics through the close cooperation between the vehicle makers and mobile communication companies. However, there may be the degradation of the quality of service by the interference since the telematics uses the wireless communication infrastructure for the base station-to-vehicle communication and the vehicle-to-vehicle communication. This paper presents an analysis device to easily analyze the interference by the wireless communication in the vehicle wireless network environment. Using the analysis results by the presented device, this paper shows that the link quality can be improved through the simulation and the experiment in real environment both.
