초록

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.
