Summary:
In the last few years, there has been an intense proliferation of broadband wireless communications (DVB-T, LTE, WiMAX ...) with excellent results in open areas. However, there is a lack of knowledge regarding how such broadband signals are propagated inside complex environments like railway tunnels or stations. Communications on this points are very important for passengers and also for the management and traffic control systems of the trains. Therefore, the aim of the presented measurements is to model the response of the broadband channel at 1000 MHz and 2450 MHz. For this purpose a measurement campaign has been conducted in the Metro of Madrid, focusing on three types of scenarios: subway stations, straight tunnels and a train blocking the signal.
