Abstract

As well as to operate a high-speed rail, our country with capability to produce high-speed train has developed a number of techniques, such as for a riding comfort improvement, automatic diagnosis for major electrical or mechanical parts, on board measurement for catenary systems and noise reduction of running rolling-stocks are still under development. In this paper, we describe the current status of operation technologies not only traditional railway wireless communication systems but also Long Term Evolution systems which would be deployed as soon as possible, like as in Europe, China and the United States. In addition, we produced the domestic wireless communication networks for railway which KORAIL Corp. has been operating and the schemes and the plans of HSR field test for the fourth generation mobile communication which should be enforced by national research and development.

고속철도를 운영할 뿐 아니라, 고속열차를 생산하는 우리나라는 고속철도를 효율적으로 운용하기 위해 각 분야에서 승차감 향상, 주요부품 자동진단, 차상 전기검측, 소음저감 등 여러 가지 기술을 개발하고 있다. 본 논문은 그 중에서도 철도 무선통신분야의 기술을 이해하기 위해, 유럽과 중국 및 미국의 철도 무선통신시스템의 운용현황을 설명하고, 국내 철도에도 적용될 철도용 LTE 시스템의 기술현황을 소개한다. 아울러 현재 운용하고 있는 국내 철도무선통신망 현황과 4세대 무선통신망에 대한 국가연구개발사업의 개략 및 고속철도 현장에서의 시험계획을 소개한다.
