Cobham connects 100th metro line in China

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

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

The company deployed its first 800 MHz TETRA system in China’s underground public transport system in 2005, when the Nanjing line 1 opened.

Since then, Cobham’s technology has been installed on metro lines across 30 cities in mainland China, including Beijing, Shanghai, Guangzhou, Nanjing, Wuhan and Chengdu, etc.

Beijing’s New Airport line incorporates an 800 MHz TETRA system, which provides communications for the metro line’s train drivers.

Previous deployments have included both this system and a 350 MHz TETRA public safety communications system.

Cobham Wireless’s TETRA products are able to extend the reach of a base station into underground environments.

“Deploying connectivity on the 100th metro line in China is a landmark moment for Cobham Wireless,” said Cobham Wireless Sales Manager, China Bret Li.

“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!” he said.

“Cobham Wireless’s repeaters can withstand this tough environment, and thanks to this latest deployment, we’ll be helping to ensure the safety of the 12 million or so passengers which use Beijing’s metro daily.”

The company’s software-based technology enables new features and capabilities to be easily installed, futureproofing the system and lowering CapEx, and are easily configured either locally or remotely via a simple graphical user interface or using the Cobham Wireless Active Element Manager system.
