These days, interest in radio networks for railways has increased both at home and abroad. In response to this trend, not only the existing radio networks which focus on railway control signals but also the next-generation integrated radio network that can send videos and manage mass storage data are actively being investigated. This paper proposes wireless communication methods to establish integrated radio networks for railways. The paper further suggests a candidate frequency band that could be allocated as the frequency band for railways among the frequency bands currently used in Korea. Based on this paper, we can expect that the domestic railroad will operate more efficiently and that security and convenience of the railroad will reach a superior level. In addition, the Korean integrated radio networks for railways, which cope with the changes in the global technology market, will be established.

현재 국내외적으로 차세대 철도 무선망에 대한 관심이 높아지고 있으며, 지금까지 열차제어신호 중심의 철도무선망에서 영상 및 대용량 데이터를 전송하기 위한 철도통합 무선망에 대한 연구가 진행 중이다. 본 논문에서는 철도통합 무선망 구축을 위한 무선통신방식과 우리나라에서 사용하고 있는 주파수대역에서 철도 전용주파수 대역으로 할당이 가능한 후보 주파수대역을 제안한다. 본 연구내용은 국내 철도의 열차 운행효율 향상은 물론 철도의 안전성과 편의성 최적화에 기여할 것이며, 세계 기술시장 변화에 대응하는 무선통신기반의 한국형 철도 통합무선망 구축을 실현 할 수 있을 것으로 예상된다.
