Defining the CBTC over LTE interface: riding the wave

This paper examines the requirements that a radio data transmission network needs to meet to serve as the train-to-shore radio bearer for a Communications-Based Train Control (CBTC) system. Those requirements are first considered through a data traffic modelled, and then mapped against the capabilities of a Long Term Evolution (LTE) radio network, in order to identify the necessary configuration parameters and the network architecture. The examination of the resulting parameters and architecture characteristics lead the author to conclude that public mobile telephony LTE networks may not be suitable to support CBTC systems, although private LTE networks can be configured to fulfil that mission.
