RFS Enables In-Tunnel Wireless Broadband Network for China’s Dongguan Rail Line

Shanghai, January 22, 2014 - Radio Frequency Systems (RFS), the global wireless and broadcast infrastructure specialist, today announced that its RADIAFLEX® line of radiating cables has been selected to provide high-capacity, in-tunnel wireless broadband coverage for the Dongguan Rail Transit R2 Line currently under construction in China. Once installed, the new wireless network will enable mission-critical and public wireless communications along the tunnels between New Dongguan Railway Station and Humen Railway Station.As the main traffic channel for the economic corridor of west of Dongguan, the R2 Line is an important part of the Dongguan rail transportation system. When it is completed, it will serve as a key connection between Guangzhou-Shenzhen Railway, central urban areas, important economic centers in the southwest, and the Guangzhou-Shenzhen-Hong Kong Express Rail Link. Construction on the first section of the R2 Line between New Dongguan Railway Station and Humen Railway Station was started in March 2010 and is scheduled to be completed by 2015.

“RFS RADIAFLEX cables will be installed to provide wireless broadband coverage along the 33.7 km of underground tunnel, which accounts for 89 percent of the total length of this section of the R2 Line,” said Golden Nie, Wireless Indoor Product Group Director of RFS Asia. “The tunnel is longer and the distance between stations is farther on Dongguan R2 line than most of other metro lines. This means the wireless network in the tunnel must meet higher performance requirements to provide the coverage needed to enable TETRA and public wireless communication along the rail line. Our RADIAFLEX cables are specifically designed for these types of applications.”

The RFS RADIAFLEX suite of radiating cables is designed to provide wireless broadband coverage for confined areas. Each cable features RFS’ patented higher order mode suppression technique in radiating cable design. This unique design allows RFS to offer cables that support current and future indoor commercial and TETRA radio services from 698 MHz to 2700 MHz — including LTE — for valuable cost savings. The broadband feature enables cables to work on different bands in one single coverage system, thereby supporting multiple carriers and multiple standards. Radio signals leaked from the apertures on the radiating cable’s outer conductor provide reliable wireless coverage for confined areas, like tunnels, ensuring that passengers on a rapid transit system can access the best quality wireless services.  

For this application, RFS is providing its industry-leading RADIAFLEX RAY family and RLK family of radiating cable products and solutions.

The RFS RAYU158-50JFNA radiating cable features a low coupling loss, which has made it the best choice for TETRA communication systems in rail tunnels. It is currently deployed along several major urban rail lines in China and it will support mission-critical wireless in-tunnel communications in the R2 Line tunnel.

The RFS RLKU158-50JFNA radiating cable will provide coverage for commercial communications in the R2 Line tunnel. With its wideband features, it can support a wide range of cellular wireless technologies, including GSM, CDMA, DCS and UMTS for today, as well as LTE (4G) in the future. The wideband feature enables it to work well in different frequency bands, allows one communication network to serve multiple standards and systems, and provides perfect support for the networks of China’s three mobile telecom operators simultaneously, thus enabling them to significantly save on infrastructure costs.

In addition to products and solutions, RFS will also leverage its extensive experience with project deployment and maintenance to provide 24-hour project support services to the Dongguan Rail Transit Company. This will ensure the successful implementation of the project within the required timelines.
