The Tetra system will comprise a switch at the core of the network, 23 base stations and seven Dispatcher Station Controllers (DSC), making it possible to communicate with users in the field equipped with a Tetra portable radio.

EADS subsidiary and security systems provider Cassidian has been selected to deliver digital Tetra (Terrestrial Trunked Radio) radio communication coverage for the metro line in Zhengzhou, the capital city of Henan province in the Central Plains of China.

It is planned to build six metro lines in Zhengzhou with a total length of 189 km. The construction will be divided into three phases. In the first phase will be to build Metro Line 1, covering a total length of about 35 km and serving 22 stations.

This line will enter service in 2013. The radio communication system for this metro line in Zhengzhou is to be installed by Cassidian and will be an element in sharing a single control centre with the other five lines scheduled for construction by 2015.

The Tetra system will comprise a switch at the core of the network, 23 base stations and seven Dispatcher Station Controllers (DSC), making it possible to communicate with users in the field equipped with a Tetra portable radio.

The system will provide perfect communications support for train dispatching, operation and management, and security for the Zhengzhou Metro; it will serve about 400 mobile users daily. Cassidian will install the entire Tetra system and provide the necessary training and related technical support services.
