Cobham Wireless announced that it has delivered a critical communications system on Beijing’s New Airport metro line, marking the company’s 100th deployment in China.

Cobham Wireless’ TETRA products are now providing coverage for driver and public safety communications across an estimated 77% of the country’s metro system.

Cobham Wireless deployed its first 800MHz TETRA system in China’s underground public transport system in 2005, when the Nanjing line 1 opened. Since then, the company’s technology has been installed on metro lines across 30 cities in mainland China, including Beijing, Shanghai, Guangzhou, Nanjing, Wuhan, and Chengdu etc.

Cobham Wireless claims that its equipment has been installed in over 70% of the world’s metro systems.

The 100th project, for Beijing’s New Airport line, incorporates an 800MHz TETRA system, which provides essential communications for the metro line’s train drivers. Previous deployments have included both this system and a 350MHz TETRA public safety communications system.

Cobham Wireless’ TETRA products are able to extend the reach of a base station into underground environments. The company said it has provided a cost-effective solution to delivering coverage throughout China’s metro system, as its technology reduces the number of base stations needed to operate a network, reducing CapEx and OpEx.

China presents a unique set of challenges for comms technology; temperatures can soar to 50 degrees in the summer and plunge to minus 30 in the winter! To guarantee passenger and driver safety, equipment must be robust and reliable, and able to run 24/7 throughout the year.
