For mainline train control, ETCS (European Train Control System) L2 uses GSM-R as radio data bearer.

For urban train control, CBTC (Communications-Based Train Control) is based on secure WiFi. 

Operations for rail operators need secure and reliable communications, this is why Thales provides Tetra network in stations and for on-board operations: emergency calls, public address, etc.

For the security of passengers and operations, LAN and secure WiFi serve real-time videosurveillance in-station and on-board, site protection, emergency call-points…

The mobile workforce grows by 6% every year. Mobile workers need to connect their smartphones and tablets everywhere anytime. Offering broadband radios or Internet access provision in station and on-board as Wi-Fi, 3G, 4G, is required today for passengers’ convenience.
