5G Channel Performance in Licensed Spectrum: Experiments on an FRMCS Testbed

In this paper, we provide a comprehensive evaluation of 5G technology within the railway communication systems which holds immense promise for revolutionizing the efficiency, safety, and connectivity of the rail networks. In this study, we establish a test field to examine the behavior of 5G signals along railway tracks. Our study outlines the technical requirements for the implementation of 5G within future railway mobile communication system (FRMCS) infrastructures, encompassing critical factors such as physical layer (PHY) key performance indicators (KPI), reliability, coverage, and specific usage scenarios. Through testbed outdoor measurements, we compare empirical findings with predefined models to discern the efficacy of 5G in railway environments. This research offers valuable insights into the viability and potential challenges of integrating 5G within the railway industry, paving the way for enhanced operational efficiency and passenger experience in the future of rail transport.
