Airbus TETRA for Chinese metro

A digital TETRA communication system will be supplied by Airbus for metro lines in Chongqing, China.

The system will be implemented on four underground lines, with three switch centres to support cross-line train dispatching, operation and security.

It will become the first project to support operations across multiple underground lines within the Chinese metro sector.

For Chongqing Metro Lines 4, 5, 10 and the circular line, Airbus will supply 93 TB3 base stations, as well as 2626 TH1n and 385 TMR880i TETRA radios. For the first time in the Asia–Pacific region, Airbus will install three Taira TETRA servers — a compact, virtualised and cost-efficient solution to replace conventional TETRA switches.

The four lines are expected to come into operation from December 2017 onwards. 

The systems will offer optimal communication support for dispatching and managing the trains, ensuring smooth and secure operations for the metro.
