무선통신 기반 열차제어시스템 구축을 위한 대불선 무선 환경 분석

초록

Train Control System is a safety system controls headways and the route to prevent train collisions and derailment based on train position. Radio Frequency Communications Based Train Control System (RF CBTC) uses the telecommunications between the train and track equipment instead of traditional signalling system such as track circuits to improve headways and safety. The spectrum for the railway is not licensed. The 2.4 GHz ISM band is commonly used in these systems although many unlicensed devices can cause interference to RF CBTC. To avoid the interference and optimize the network performance, wireless environments near the Dabul line were surveyed.
