Airbus to Supply TETRA Network for Chongqing Metro
Thursday, April 13, 2017 | Comments

Airbus signed a contract to provide a TETRA system for four underground lines in Chongqing, a city of about 18 million inhabitants, making it the largest in southwest China.

Chongqing Metro will install a single TETRA radio communication system across its four metro lines, with three switch centers 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 base stations, 2,626 portable radios and 385 mobile radios. For the first time in the Asia-Pacific region, Airbus will install three TETRA compact, virtual servers to replace conventional TETRA switches. The four lines are expected to come into operation in December.

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