Radio Frequency Systems (RFS) has announced that it has deployed an in tunnel coverage system for the tunnels on the Guangshen section of China's Guangzhou Shenzhen Hong Kong Express Rail Link (Guangshengang XRL).
As a significant strategic national express rail project that connects Hong Kong to the national express rail network in the Mainland, Guangshengang XRL has a total distance of 142 kilometers, and features 26 newly built tunnels.
Shiziyang Tunnel, with a length of 10.8 kilometers, is the longest underwater shield tunnel in China and is designed for speeds of up to 350 km/h - the fastest underwater railway tunnel in the world.
The commercial communications coverage solution provided in the tunnels is jointly owned by China Mobile, China Telecom and China Unicom, supporting the three operators' multiple applications.
In addition, all the radiating cables provided are flame- and fire-retardant, and the clamps installed are flame-retardant, which ensures communication between train and railway control centers even in the event of fire.
