Huawei and Alstom announced the successful completion of the world’s first live pilot test of 4G LTE multi-services based on Communications-based Train Control (CBTC), a railway signaling system based on wireless ground-to-train communication.
The successful pilot, which covered the unified multi-service capabilities of several systems including CBTC, Passenger Information System (PIS), and closed-circuit television (CCTV), marks a major step forward in the LTE commercialization of CBTC services.
Alstom is the world’s first train manufacturer to integrate LTE 4G into its signaling 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.
The LTE pilot project was launched after a Memorandum of Understanding (MoU) signed between Huawei and Alstom in April 2014, which agreed to Huawei providing the eLTE network required for the pilot, and Alstom providing the train and LTE-compliant onboard equipment.
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.
