Network design rules of communication systems at train stations based on intensive measurement campaigns

This paper presents a series of network design rules of communication systems at train stations based on intensive measurement campaigns. The measurements are conducted on various train stations of a high-speed railway in China at 930 MHz. The measurement campaign is designed and realized by all the combinations of four conditions: the distance between the transmitter (Tx) and the train station, the type of the train station, the track carrying the train, and the propagation mechanism zones. Based on the propagation characteristics (extra propagation loss, shadow fading, small-scale fading, and fading depth) extracted from the measurement results, four rules for the network design in the train station scenario are provided. The rules are useful to involve the train stations in the network design of signaling and train control communications systems.
