In the years to come, the Future Railway Mobile Communication System will replace the established GSM-R as communication standard for international railway networks. Based on the 5G standard it is being standardized but promises significant higher data rates and allows the realization of new applications.

This course describes the current state of the development, shows the railway-specific requirements and shows which new use cases will become viable. The 5G-standard will be explained as far as needed to understand FRMCS, as well as the Mission Critical Service (MCX) architecture, upon which FRMCS will be based.

Target group/ Prerequisites

Technicians and engineers of railway companies as well as of mobile network providers, which want to learn about this new standard. The participants should already know about GSM-R and should have a technical background.
