Airbus Defence and Space has been awarded critical communications contracts for the metro lines of three large cities in China. It will provide TETRA systems for the new lines of the provincial capitals Lanzhou and Urumqi in central and north-western China. Network roll-out has started recently for both projects. The company will also provide a TETRA system for the existing line 2 in Qingdao.

Lanzhou’s roughly 34 km long metro line will be served by a TETRA switch, 22 TB3 base stations and approximately 500 THR880i and TMR880i terminals. The network is scheduled to start operation at the end of 2017. The city, which is the capital of Gansu province, plans to have six metro lines in the future.
In Urumqi, the capital of the Xinjiang Uyghur Autonomous Region, 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 1” is the latest version of a full-IP TETRA network with a disaster recovery mechanism. The metro system is expected to start its service in 2019.
The transport authority of Qingdao, on China’s north-eastern coast, has ordered a TETRA communication system for its metro line 2. Qingdao has been running an Airbus Defence and Space TETRA network, since last December, to dispatch, operate and manage the trains of its line 3.
