Private LTE, maximum availability and quality of service for CBTC applications

TELTRONIC’S LTE SOLUTION COMPLIES WITH THE TECHNICAL REQUIREMENTS FOR PROPER ENT-TO-END OPERATION OF SIGNALLING SYSTEMS.

Railways, metros and trams need efficient communications network capable of providing the degree of availability and meet the security requirements of this kinf of environment.

Teltronic’s LTE solution complies with the technical requirements for proper ent-to-end operation of signalling systems and, recently, has been certified by CAF signalling after the successful integration with its CBTC applicaction.

The field tests carried out in Bilbao Metro Line 3 on a real operation scenario proved that Teltronic’s solution, consisting of its eNEBULA LTE infrastructure and its cutting-edge onboard terminal RTP-800, allows the correct operation of the signalling system up to the highest levels of train automation.

From the experience it is concluded that LTE technology is ready to be used in the deployment of CBTC systems, offering the optimal parameters in terms of availability, minimum latency and continuity and Quality of Service, and that a private broadband system provides reliable and efficient communications in railway environments through a single infrastructure.

In the face of the shortcomings and drawbacks of the wireless systems currently used in signalling applications, such as Wi-Fi, LTE technology provides an end-to-end solution that combines trackside infrastructure and onboard equipment, and which meets both the requirements of railway signalling data management and compliance with railway standards.

This project with CAF Signalling may be applicable to other transport environments with signalling systems based on different existing protocols such as ETCS or PTC.
