To ensure smooth operations and efficient fleet management, various communi- cation needs arise. This paper outlines four common use cases and identifies nine communication requirements for the MONOCAB. Based on this, it presents a communication concept utilizing 5G technology, covering Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication, as well as time critical communication to an edge application in a central control centre and non-time critical communication for fleet management and provision of information for the MONOCAB users.en5G communicationrailwayV2XRemote controlSecurityconference paper
