5G4Rail - 5G mobile radio requirements for safety-relevant railway applications
The WIR! project “5G-4-Rail” at the Smart Rail Connectivity Campus (SRCC) is to investigate how the 5G mobile radio standard can replace the previous system "GSM-R" (Global System for Mobile Communication - Rail) in the railway sector in the future and also be used for more extensive, future application areas in the railway system of the future like autonomous driving. The motivation lies in the fact that, on the one hand, GSM-R will be phased out in the foreseeable future (2030). On the other hand, the bandwidth of data transmission with GSM-R is limited to a low value. The future railway control and safety technologies (LST) will be fully digitalised and an essential building block for this is a powerful and reliable wireless communication system. The aim of the analyses is to select specific use cases that require "limit values" for the performance parameters of the mobile network. Another project goal is the development of measurement and test scenarios with which the properties of mobile radio can be characterised in terms of Quality of Service (Latency, reliability and availability). In a practically oriented part of the project, these scenarios are to be implemented in measurement and test campaigns with the 5G infrastructure at the SRC-Campus, Erzgebirge.
