SAFRON: Safe operational radio network for mixed-priority communications to trains using a shared architecture

Start date

01 December 2018

End date

30 June 2020


The SAFRON project aims to create a prototype to demonstrate how wireless networks (WIFI, LTE and 5G) can be used to train the trackside communications for mixed applications including those which are safety related and mission critical.

We are collaborating with Surrey’s 5G/6G Innovation Centre to oversee the security analysis and design of the communication between the train systems and the rail route control centre, using secure tunnelling techniques.
