Alstom and Huawei have completed a trial to develop Long Term Evolution or LTE 4G multi-service broadband radio networking technology for metros.

Alstom trials LTE 4G for metro signalling solution

A Memorandum of Understanding was signed in April 2014 between telecommunications equipment producer Huawei, which supplied the LTE network, and Alstom which provided the train set and onboard signalling equipment.

LTE technology enables a single wireless communication system supporting mission critical voice trunking and video communications, communication-based train control (CBTC) and broadband data applications such as passenger information systems and live streaming of CCTV images. Alstom will be the first train manufacturer to implement LTE 4G in its signalling solution. Alstom and Huawei believe the wireless system will improve operational services, reinforce security controls, enable remote diagnostics of onboard equipment and reduce operational costs. The LTE 4G technology also allows passenger information to be obtained quickly, therefore greatly improving the serviceability of trains.

Alstom has installed the LTE 4G technology on metros enhancing its CBTC solution Urbalis. A number of static and dynamic tests have successfully taken place at the manufactures Valenciennes site in France.
