Huawei announced that Communication Based Train Control (CBTC) over Long Term Evolution (LTE) joint solution validation passed the interoperability testing in France at the end of 2015. The project was jointly carried out by Huawei and Siemens.
During the testing, multiple types of service, including CBTC, Passenger Information System (PIS), and Closed-circuit Television (CCTV), were carried using one radio technology – LTE, laying a solid foundation for commercial rollout of CBTC over LTE service.
The collaboration between Huawei and Siemens started in March 2015, when the two companies discussed technical solutions and confirmed preliminary plans and schedule for cooperation in Huawei’s Shanghai-based wireless R&D center. In June 2015, the two companies set up a joint project plan, and a project team defining solution architecture and feasibility of testing in France.
In November 2015, with technical guidance and onsite support from Huawei, Siemens France quickly completed successfully a large number of laboratory tests, where CBTC, PIS, and CCTV services were successfully carried over an integrated Airlink LTE solution.
The next step for this joint solution would be the on-site dynamic test, which will take place in the coming month.
