Huawei and Alstom completed a live pilot test of LTE multi-services based on Communications-based Train Control (CBTC), a railway signalling system based on wireless ground-to-train communication. The testing covered the unified multi-service capabilities of several systems including CBTC, Passenger Information System (PIS), and closed-circuit television (CCTV).
The pilot was carried out at metro lines near the Valenciennes commune area in France with Huawei optimizing the network planning, broadband data services, and mission critical voice trunking services, and Alstom providing the technology integration support. During the pilot, Huawei and Alstom jointly conducted several tests, including laboratory and static test on trains, dynamic test on metro tracks, and testing of eLTE multi-services capabilities.
Alstom is the world’s first train manufacturer to integrate LTE 4G into its signalling system solution, the Urbalis Fluence CBTC solution, which greatly improves the suitability of eLTE, providing a converged ground-to-train wireless communication network for metro operations.
Huawei said it first developed the eLTE broadband trunking solution with a focus on multimedia applications, voice trunking dispatching, and broadband data services based on 4G LTE standards to satisfy growing demands from the rail transportation industry.
Huawei’s eLTE solution enables metro operators to ensure safe train operations by leveraging eLTE-based CBTC train signals while providing mission critical voice trunking dispatching and broadband data services such as live video streaming of CCTV images and Passenger Information System (PIS).
To date, Huawei has signed 111 eLTE network contracts and established 53 eLTE commercial networks in more than 30 countries. Huawei’s eLTE solution has also been successfully deployed in a number of railways around the world.
