Airbus TETRA technology deployed on Chinese metro

Digital TETRA communications systems for the metro lines of three cities in China will be supplied by Airbus Defence and Space, to ensure secure operations.

Lanzhou, Urumqi and Qingdao are included under the contract, where implementation of the systems has already begun.

With a total length of approximately 34 km and 20 stations, Lanzhou’s metro line will consist of one TETRA switch, 22 TB3 base stations and approximately 500 THR880i and TMR880i terminals. The capital of Gansu province plans to have six metro lines in the future.

In Urumqi, Airbus Defence and Space will provide two DXTA TETRA switches, 23 TB3 base stations and around 500 TMR880i and TH1n terminals. This system for Urumqi’s metro line one is the latest versions of a full-IP TETRA network with a disaster recovery mechanism. The metro system is expected to start its service in 2019.

In addition, the transport authority of Qingdao, on China’s north-eastern coast, has ordered a TETRA communication system for its metro line two. Since December 2015, Qingdao has been running an Airbus Defence and Space TETRA network to dispatch, operate and manage the trains of its line three.
