Abstract
En 中文
Modern trains have become a complicated ensemble of both mechanic and electronic systems. In particular, the so called Train Control and Management System (TCMS) plays a key role in them. TCMS-related applications and services run over a dedicated network called TCN (Train Communications Network) which is wired. Therefore, the opportunity for a wireless TCN is clear, but the challenges and threats are also remarkable. In this article we characterize the radio channel for a very important scenario: the train backbone, which includes the impact on adjacent trains (due to interferences). In order to be exhaustive and to provide useful and accurate models, a measurement campaign on three different real-world scenarios (with trains involved) has been carried out: tunnels, open air and stations. Physical layer results are provided in terms of path-loss, power-delay profile and fading distribution characterization.
