Communication to and in trains

In this paper, communication with and inside trains is analysed. Existing communication links to trains are exemplified. A semi-automated planning tool for basic calculations of the positions of base stations is shown. It is detailed, how this tool may simplify the planning process for different usage scenarios. In addition, the distribution of signals inside and between the train's coaches is described. Both together can be used for cost calculations for operators intending to offer a certain service to train passengers. An outlook towards future use of communication inside trains is given at the end.
