Radio Frequency Systems (RFS), the global wireless and broadcast infrastructure specialist, announced that 2014 was another record-breaking year for deployments of its RADIAFLEX® and CELLFLEX®cables and related products.The company’s market-leading passive and active in-tunnel and in-building wireless networking solutions were used by major mobile operators and integrators to deliver uninterrupted coverage and capacity in some of the most challenging indoor venues around the world, including office buildings, research centers, metro rail tunnels, road tunnels, airports, exhibition grounds and stadiums.

Major RFS successes in 2014 included deployments in:

  • Algeria: A rail network for Metro Algier
  • Brazil: Four stadium networks for the 2014 FIFA World Cup; multi-operator wireless in-building networks for five buildings of the Administrative Center of the Government of Minas Gerais (CAMG)
  • China: Rail networks for DonggGuan Rail Line, Dalian Metro and Ningbo Line 1 and 2
  • France: A rail network for Project Orange Cameroun; an in-building network for Project Etihad Etisalat Company
  • Germany: In-train networks for Intercity-Express (ICE); an in-tunnel network for Metro Munich; in-building networks at the European Central Bank (ECB) in Frankfurt, Deutsches Elektron-Synchroton (DESY), Airport Hamburg, the Mercedes factory in Sindelfingen, a power plant of Vattenfall, and a hospital in Villingen; as well as a Terrestrial Trunked Radio (TETRA) network for a street tunnel in Munich
  • India: A TETRA radio system for Delhi Metro Rail Corporation (DMRC) in Delhi
  • Malaysia: A rail network for Metro Kuala Lumpur
  • Norway: Rail networks for the Oslo Metro and Lieråsen rail tunnels; a road network in the Lærdal Tunnel; and an in-building network at Tjuvholmen parking house
  • Philippines: In-building networks for the Huawei complex
  • Singapore: Rail networks for DownTown Line 3 and DownTown Line Commercial
  • Spain: Rail networks for Ferrocarriles de la Generalitat and Catalunya GC; an in-tunnel network for Madrid-Galicia Vigo Das Maceiras; and an in-building network for Plaza de España-Can Tobella
  • U.S.: Rail networks for Amtrak and Metro North Commuter Rail; metro networks for Los Angeles County Metro and King County Metro in Seattle, Wash.

“These and other projects in 2014 are excellent examples of the flexibility our cables, jumpers, splitters, connectors and accessories provide to operators around the world for in-tunnel and in-building wireless networking,” said Peter Raabe, RFS Global Product Line Director, Transmission Lines and Wireless Indoor Solutions. “With RFS solutions, operators have a variety of options to deliver wireless service wherever their customers are and provide the quality of experience today’s end users expect at all times, whether they are sitting at a desk in an office, traveling through a tunnel on a metro train on their way to work, or enjoying a sporting event in a stadium.”

RFS in-tunnel and in-building wireless networking solutions have been proven under the most demanding conditions. For example, fans at the final match of the 2014 FIFA World Cup at Maracanã Stadium in Brazil had no trouble sharing the drama on the field and the experience in the stands with friends and family over the advanced, wireless, multi-operator Distributed Antenna System (DAS) solution provided by RFS. Reports released by Sinditelebrasil and the Brazilian Ministry of Communications show that the multi-technology wireless network infrastructure provided by RFS supported a data traffic volume of 1.5 Terabytes, which is equivalent to 2.6 million photos with an average size of 0.55 MB. Using cell phones, smartphones and tablets, the 74,000 fans inside the stadium generated this traffic over a seven-hour period, as well as 618.725 tweets per minute and 280 million posts on Facebook.

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 essential radio services from 30 MHz to 2700 MHz and above 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. 

RFS CELLFLEX foam dielectric feeder cables provide a reliable and technically superior solution when used as backbone feeders in cellular radio systems, including GSM, UMTS and LTE networks. They can also be used for DAS radio equipment interconnections and jumper assemblies. Once installed, these cables ensure uninterrupted communications with low attenuation and complete shielding. Special low-voltage standing wave ratio (VSWR) variants are available to help maintain system integrity at all times. And a full range of flame- and fire-retardant feeder and radiating cables is available, which meet most stringent requirements and safety standards for indoor applications.
