RADIO COMMUNICATION SYSTEM OF TRAIN BY TRANSMISSION CHANNEL CONTROLLING

摘要

PURPOSE: A radio communication system of a train by transmission channel controlling is provided to implement a stability of driving a system by securing normal communication between an on-board device and a ground device. CONSTITUTION: A wireless telecommunications system comprises a ground wireless communication apparatus(200) and an on-board wireless communication apparatus(300). The ground wireless communication apparatus transmits wireless link information, and it receives data which is transmitted through a plurality of wireless channels and combines it. The on-board wireless communication apparatus receives the wireless link information from the ground wireless communication apparatus. When wireless data is allowed to be transmitted or received, the on-board wireless communication apparatus forms a wireless channel with a main channel.
