Huawei and Alstom, have together announced the successful completion of the world’s first live pilot test of 4G LTE multi-services based on Communications-based Train Control (CBTC). The pilot project, which includes Passenger Information System (PIS) and live streaming of Closed-Circuit Television (CCTV) images marks a major step forward in the LTE commercialization of CBTC services. The pilot was carried out in dynamic conditions on metro lines near Valenciennes in France and saw Huawei optimizing the network planning, broadband data services, and mission critical voice trunking services, and Alstom providing the technology integration support. The development aims to improve operational services, reinforce security control and enable remote diagnostic of the on-board equipment while reducing operational costs.
The project was launched in the frame of a Memorandum of Understanding signed in April 2014 between Alstom and Huawei. Alstom is the world’s first train manufacturer to integrate LTE 4G into its signalling system solution, the Urbalis Fluence CBTC solution, which 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 on-board equipment.
Huawei 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. LTE 4G technology enhances Alstom’s world-leading CBTC solution Urbalis that equipped cities all over the world, representing 25% of CBTC solutions deployed worldwide.
