Abstract: During the railway engineering design, it is difficult to quickly evaluate the influence of the superstructure architectural structure on the wireless network coverage in the facilities, which leads to the difficulty of wireless network planning. In order to solve the problem, this paper studies the wireless coverage prediction method in EMU depot with superstructures, performs ray-tracing simulations based on BIM model to simulate the wireless coverage in the depot, explores 3D modeling method to support the ray-tracing algorithm in high efficiency, and discusses the rules of wireless system design in similar railway environments, so as to guide further wireless network planning.

Key words: ray-tracing, EMU depot, superstructures, wireless coverage prediction
