摘要：

This paper presents extensive propagation measurements conducted in a modern arched tunnel with 300 m and 500 m radii of curvature with horizontal polarizations at 920 MHz, 2400 MHz, and 5705 MHz, respectively. Based on the measurements, statistical metrics of propagation loss and shadow fading in all the measurement cases are extracted. Furthermore, for each of the large-scale fading parameters, extensive analysis and discussions are made to reveal the physical laws behind the observations. The quantitative results and findings are useful to realize intelligent transportation systems in the subway system.
