All in all, it is an exceptionally well-organised event, and I was privileged to be invited to present a technical paper for a second consecutive year.
With the last two years or so experiencing the rumblings of a quiet revolution in the CBTC arena, the topic I chose to speak on was Communications-Based Train Control (CBTC) over the LTE interface.
The technical presentation examined the requirements that a radio data transmission network must meet to serve as the train-to-wayside radio bearer for a Communications-Based Train Control (CBTC) system. Those requirements were first considered through a data traffic model, 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 to conclusion 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.
The moment, I believe, is ripe for the greatest technology swap in over a decade.
The full White Paper is now available and I invite you to download the paper.
