무선 통신 기술 발전을 통하여 철도환경에서 안정적인 무선 접속과 다양한 통신 기능 제공이 가능함에 따라 철도서비스 고도화의 기반이 마련되었다. 특히, 최근의 무선 통신 기술은 향상된 철도 승객서비스뿐만 아니라 효율적이고 안전한 철도 운영을 가능하게 한다. LTE 기반의 무선통신 기술은 다양한 경제적 혜택과 높은 통신 성능을 철도 산업에 제공 가능함에 따라 세계적으로 차세대 철도 통신 시스템의 후보 기술로 각광받고 있다. 그러나 철도 통신은 열차의 안전한 운행을 위하여 매우 엄격한 철도 통신만의 요구 사항도 존재한다. 본 논문에서는 미래의 철도 통신이 반드시 갖추어야 할 요구사항과 기능을 설명한다. 또한 LTE 무선 통신 기술이 철도 분야의 통신 요구사항을 만족하는지에 대해서도 서술한다. 마지막으로 최근 진행되고 있는 차세대 철도 통합무선망의 국내외 표준화 동향과 구축일정에 대하여 설명한다.
