Influence of Railway Infrastructure on Train-To-Train Communications [PDF]
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021 The future of railway operation will rely on train-to-train (T2T) communications. Hence, we investigate the propagation mechanisms based on channel sounding measurements and derive channel models for T2T communications. For every wireless communication, the environment significantly influences the wireless propagation.
