Abstract

This paper shows the results of a communication range measurement campaign performed with mobile onboard units of a fully de-centralized train collision avoidance safety overlay system in typical environments of sparsely used railway lines. The most critical sections of the track with respect to a direct train-to-train communication channel were identified and selected for measurements in different antenna configurations. The measurement results justify the conclusion that the direct train-to-train communication channel along typical sparsely used railway lines fits the requirements of mobile onboard units of the train collision avoidance system.
