Channel characterization and modeling are very active topic, thanks to the development of the 5G and beyond. From vehicle-to-vehicle to train-to-train environment the characterization of the channel for mmWave (millimeter Wave) is a hot topic. In [1], a radio link on railway track from Naples to Rome is investigated with different scenarios from platoon to overtakes. Those measurements were performed with the RUSK-DLR channel sounder. Moreover, in [2] static measurements were performed with a regional train. The vehicle-to-vehicle is investigated by the channel sounder from the Brno university in [3] two cars passing towards and away each other. In the case of an ANR project, mmw4Rail, we want to contribute to the modelization of the propagation channel for mmWave in railway environment.
