Abstract (EN): The transportation sector has been searching towards intelligent transportation systems. Vehicle-to-Infrastructure communication allows the transportation sector to pursue this objective, e.g. by increasing infrastructure capacity, by having interconnected vehicles, etc. In the railways domain, similar approaches are under consideration: e.g. for higher level of interoperability, the vehicles have started recently to report detailed energy consumption information to base stations. A possible solution to collect the maximum and appropriate amount of energy data, while keeping the costs low is studied in this work. In this work it is proposed the usage of the most recent IEEE 802.11 Wi-Fi technologies to exchange the Compiled Energy Billing Data (CEBD) between the trains and passenger stations. With this proposal, the energy meter system generates two types of energy data, one of them with a low frequency rate (but enough to fulfill the EN 50463 requirements, specifically 5 minute between samples) and the other energy data with a higher sample rate. The first energy data will be transferred by Long Term Evolution (LTE) and the other more detailed energy data will be transferred via Wi-Fi. As a practical evaluation of a sub-urban railway line, in this work were considered two case studies. In the first one, the train will stop in every station. In the second, the train will not stop in any station. If all passenger stations are equipped with ordinary Wi-Fi access points, in the first case study, the train will be online 41% of the journey time, which allows a 5 Mbps of continuous data-rate generation. In the case where the train does not stop in any station, the train will be online 12% of the journey time, leaving a 375 Kbps of continuous data-rate generation.
