Abstract

This paper presents the fundamental study to implement the wireless data link system in the subway. The propagation characteristics of the electromagnetic wave in the tunnel are analyzed to determine the proper radio frequencies for our system. The tunnel is modeled as a circular waveguide and then, its path loss is obtained. The efficient communication control procedure is proposed, which is well suited to our system architecture and the subway environment. The prototype system shows a good performance in the data communication.
