CASSIDIAN to build TETRA network for Zhengzhou Metro Line 1 in China

13 June 2012

  • Cassidian to provide TETRA radio communication for a new metro line in the capital city of a Chinese province
  • The TETRA system will provide perfect communications support for train dispatching, operation and management, and security for the Zhengzhou Metro
  • The system will serve about 400 wireless users daily

Cassidian has been selected to deliver digital TETRA (Terrestrial Trunked Radio) radio communication coverage for the first metro line in Zhengzhou, the capital and largest 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 first metro line in Zhengzhou is to be installed by Cassidian and will be a key 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 wireless users daily. Cassidian will install the entire TETRA system and provide the necessary training and related technical support services.

Starting in 2009, China has planned to build around 80 mass transit rail lines in 22 cities by 2015. The Metro in Zhengzhou is one of them. Cassidian has already provided TETRA radio communication systems for ten other metro lines in China including Shenzhen, Hong Kong, Guangzhou, Wuhan, Shenyang and Nanjing. Galvin Wong, CEO APAC of Secure Communication Solutions at Cassidian, comments: “China has enjoyed a ‘golden decade’ of city rail transit construction, and we are committed to further supporting that challenging development. This new contract shows that our Chinese customers are relying on our advanced technology, mature products and long experience in that domain.”
