CRITICAL AND PERFORMANCE APPLICATIONS REQUIRE 5G WITH A DIFFERENT QUALITY SET
CriticalApplications• Core part of futurerail operation
• In most countries todayrequired
to be based on railway-owned
and -operated connectivity with
dedicated spectrum

TOWARDS RAILWAYS 5G SLICES
➢ Aim:
➢ FRMCS (Future Railway Mobile Communication System) is a projectdriven by the International Railway Union (UIC), a worldwide railwayassociation, dedicated to define the successor of GSM-R for a newrailways digital radio system. FRMCS will mainly use 3GPP standardssuch as LTE and future 5G
➢ 5G Slicing: develop dedicated slice for each family of applications
➢ Use cases:
➢ Critical App : Train to Ground and MCPTT
➢ Performance App : CCTV, IoT on bord
