일반 및 고속철도용 무선통신시스템의 현차시험 조건분석

Railway wireless communication methods have been operated in the way of VHF system and TRS (Astro / Tetra) system since they were adopt and constructed in the conventional lines and the high speed lines. Just as domestic rail network has various operation methods, so the Rail Traffic Control Center has to control by all three of those communication system, and KTX and KTX-Sancheon rolling stocks that runs Gyeongbu and Honam High Speed Railway have Automatic Change System to operate these three communication methods also. We have some communication shadowing area (VHF) yet, so we have to resolve this problem. In this paper, we introduce building a test railway network to the LTE applied railway, and the actual test conditions. At the end, we look at the expectation effects of domestic railroad near future.
