RF-CBTC 무선통신 신뢰성 확보 방안에 대한 고찰

Wireless Radio-Frequency communications-based train control system is gradually introduced in domestic, but advanced communication environment than any other country causes the adjacent frequency band interference through a variety of routes in a rather harsh environment, even opening these wireless communications-based train control system. Accordingly, the railway system which is requesting reliability and safety as the highest priority should be taken into consideration and be designed to address these issues by considering various way. In this paper, I propose the optimization of the configuration of the communication as a supplement. And, by composing train dual system and network dual system configuration, we hope to ensure reliability for communication.
