경산시험선 CBTC 시스템용 무선통신시스템 시험(1)

Korean-Automated Guideway Transit (K-AGT) was successfully developed through Light Rail System Development Project. Since then, the domestic development rate of on-board signalling system of light rail has been improved up to 90% by Practical Utilization Project of Light Rail. After utilization project, furthermore, POSCO ICT has developed the wayside signalling system of CBTC, including wireless communication equipment. KRRI carried out the performance test of the wireless communication, interfacing and using the other CBTC equipments of KyungSan Test Line so as to see whether it conforms IEEE 802.11x, international communication standard in view of operational concept of CBTC. In this paper, we presents the test plan, test items, and the analysis results of maximum communication distance tests between on-board and wayside radio sets.
