Networking technology company Cobham Wireless has installed a critical communications system for Beijing's New Airport metro line.

The company has provided its 800-MHz terrestrial trunked radio (TETRA) technology for the new line to provide essential communications for train drivers.

The deployment marks Cobham Wireless' 100th metro line deployment in China. The company deployed its first TETRA system for China's metro rail system in 2005 for the Nanjing Line 1.

Cobham has now deployed the technology in metro lines across 30 cities in mainland China, including Beijing, Shanghai, Guangzhou, Nanjing, Wuhan, and Chengdu. The deployments have included both 800-MHz and 350-MHz TETRA public safety communications systems.

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

“To guarantee passenger and driver safety, equipment must be robust and reliable, and able to run 24/7 throughout the year. Cobham Wireless’ 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 said its equipment has now been installed in over 70% of the world's metro systems.
