The communication services of future trains require hyperconnectivity between trains and track. Future Railway Mobile Communication System (FRMCS) reserved bands will not be able to cover all digital train requirements including passengers’ services. The 5GMED project adopts the idea where Infrastructure Managers (IMs) will collaborate with Railway Undertaking (RU) to facilitate the connectivity to Mobile Network Operator (MNO) communication services and vice versa (complemented with the use of satellite networks), with an architecture open to build new business models and relationships between stakeholders. This approach encompasses an adaptative Gigabit train-to-track connectivity solution able to fit Digital Train requirements. The 5GMED project will demonstrate these capabilities through four representative services deployed on a TGV of SNCF (French Train Operator) in a challenging scenario: a cross-border section of the Mediterranean corridor between Figueres (Spain) and Perpignan (France).
