The networks’ implementation recently began. In addition, Airbus Defence and Space will provide a TETRA system for the existing line 2 in Qingdao.
With a total length of roughly 34 kilometers and 20 stations, Lanzhou’s metro line will consist of one TETRA switch, 22 base stations and about 500 terminals. Operation will start at the end of 2017. 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 TETRA switches, 23 base stations and around 500 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 service in 2019.
In addition, the transport authority of Qingdao, on China’s northeastern coast, ordered a TETRA communications system for its metro line 2. Since last December, Qingdao has already been running an Airbus Defence and Space TETRA network to dispatch, operate and manage the trains of its line 3.
