In order to ensure the safety of the running train, wireless communication system for train communications and control must provide a network with high quality of service (QoS). And wireless network design will directly influence the performance of the whole network. In the process of the network design, choosing the appropriate prediction model, predicting the coverage, and determining base station site, are all related to the local environment. To improve the quality of the railway wireless network, the base station site selection for railway wireless network is optimized based on GIS (geographic information system). A new propagation model selection method based on GIS is also proposed. With the help of GIS, the accuracy of the prediction model and the efficiency of the base station site selection can be greatly improved.
