Radio Propagation Measurements and Modeling in Railway Viaduct Area

A network with high quality of service (QoS) is required for railway wireless communication and control systems. Research on radio-wave propagation in railway environment has great significance for the design and optimization of the railway wireless network. In this paper, measurements are taken in railway viaduct area using track side base stations of the GSM-R network. Comparison between the measured path loss values and the estimated values by a few prediction models shows a large deviation. Thus a new path loss prediction model for viaduct area is derived from statistical analysis of the measurement results in this paper. The novel proposed model has proven to be accurate for the planning of the railway wireless network.
