Abstract

The Future Wireless Railway Communication System(FWRCS) has attracted attention for the various advantages of such a system like efficient management, precise periodicity of operation and speedy travel. Related to it, the area of bandwidth requirement estimation for the FWRCS is being researched actively because there is a great need for accurate bandwidth distribution. In this paper, sophisticated bandwidth requirement estimation method for FWRCS is proposed by modifying ITU-R M.1390. With this method, the expected frequency requirements for the present, for five years from now, and for 10 years from now can be calculated by applying the data gathered from the actual field.

본 논문에서는 철도통신시스템을 위해 필요한 주파수 소요량을 계산하기 위한 방법을 제안한다. 철도통신시스템을 위한 주파수소요량 계산에 최적화된 방법을 유도하기 위하여, 먼저 기존의 일반 이동통신시스템의 주파수 소요량 측정에 사용되었던 방법인 ITU-R M.1390을 분석한 후, 차세대 철도통신시스템에서 요구하는 서비스들을 세분화하여 정의하고, 철도통신을 위해 수정된 주파수 소요량 프로세스를 제안한다. 그리고 실제 현장조사를 통해 습득된 장비정보들을 제안한 계산방법에 적용하여 현재, 5년 후, 10년 후 시점의 예상 주파수 소요량을 계산한다.
