4. Requirements for a Future System
Reliability
System needs to be reliable during its whole life time
e.g. today 100% within h (for a cab radio) A
Availability
Railway networks are operated 24h / 7d
Typical life cycle of GSM-R equipment is 15 years M
Maintainability
Modular design
Easy handling
Cost efficient
Remote access & diagnostics
Realtime?
Verfügbarkeit und zuverlässigkeit
SIL level
Mtbf nur HW wie SW fassen
