摘要

在柏林地铁中进行了一项测量活动，以表征地下铁路隧道中的电磁波传播特性。采用945 MHz和1853.4 MHz的接收功率电平来评估弯曲拱形隧道中的衰减和衰落特性。测量结果与射线光学模拟结果进行了比较。结果表明，隧道的几何形状，特别是断面形状和路线，对隧道的传播特性有重要影响，从而影响模型的准确性。

Natural wave propagation in subway tunnels at mobile communications frequencies

A measurement campaign has been carried out in the Berlin subway to characterize EM-wave propagation in underground railroad tunnels. The received power levels at 945 MHz, and 1853.4 MHz are used to evaluate the attenuation and the fading characteristics in a curved, arched-shaped tunnel. The measurements are compared to ray-optical modelling results. It is shown that the geometry of a tunnel, especially the cross-sectional shape and the course, is of major impact on the propagation behaviour and thus on the accuracy of the modelling.
