Radio-Frequency Systems - Telecommunications partner of the transportation industry

For more than 40 years, Radio-Frequency Systems has provided innovative communications solutions for the world's metros, railways, road tunnels, mines, ships and airports. Today, it offers the most advanced active, passive and hybrid RF distribution systems for in-tunnel coverage, in-building station and terminal coverage, and outdoor trackside and roadside coverage.

Transportation operators rely on mission-critical communications to ensure the safety of millions of passengers, employees and assets every day. Their solutions must enable continuous, high-quality communications across tunnels, complex in-building environments and diverse outdoor terrains. At the same time, these solutions must support commercial applications that increase passenger satisfaction and provide new revenue opportunities.

Radio-Frequency Systems' (RFS's) best-in-class communications technology for the transportation market is LTE-ready. Transportation operators can benefit from its technology advantages confident in the knowledge they can evolve to LTE when the timing is right for their business - without having to purchase additional equipment.

RFS's RADIAFLEX® suite of radiating cables showcases RFS's technology leadership. The RADIAFLEX cables feature RFS's patented 'higher order mode suppression technique' in radiating cable design. This unique design allows RFS to offer a cable series that supports current and future in-tunnel and in-building commercial and private radio services up to 2,700MHz - including LTE - for valuable cost savings. The RADIAFLEX cables also ensure low insertion loss and excellent coupling performance, and feature halogen-free, non-corrosive, low-smoke and flame-retardant jacket material for safe and reliable long-term cable operation.

The optimal confined-coverage solution

Wireless has moved indoors and RADIAFLEX is an important part of the solution. RADIAFLEX is the world's leading 'leaky feeder' cable solution. Designed to deliver contoured RF indoor coverage, RFS RADIAFLEX cables provide a scalable and practical means of tailoring RF coverage in even the most challenging confined spaces:

  • confined coverage for today and tomorrow: the RADIAFLEX family of cables features a unique broadband design, providing confined coverage solutions that will meet transportation operators' needs today and as they evolve their communications applications
  • broadband solution: RADIAFLEX cables support all major services from 75MHz to 6GHz, making them optimally suited for multioperator and multiband applications
  • flame and fire-retardant: RADIAFLEX cables are low-smoke and halogen-free to meet all major international flame and fire-retardancy standards
  • low loss: featuring low longitudinal and coupling losses, RADIAFLEX cables are available with optional 'vario' coupling loss configurations for longer installation runs
  • comprehensive range: with diameters spanning ½in to 15/8in, RADIAFLEX cables are available with different jacketing, coupling losses and bending radii.

Ideal for confined coverage applications, RADIAFLEX radiating cables support a wide range of applications including all modern cellular telecommunication standards (2G/3G/4G) as well as mission-critical communication services, such as LTE/TETRA and GSM-R services, in all applicable frequency bands. RADIAFLEX radiating cables are technology and frequency agnostic, and are capable of handling various services simultaneously on a shared infrastructure, often also combined with AM/FM radio or DAB and DVB services.

The worldwide unique RADIAFLEX RE60 radiating waveguide is the leading-edge solution for in-tunnel wireless applications in the 5-6GHz band. The innovative approach allows superior system performance, ensuring the lowest insertion loss and excellent coupling loss that is equivalent to today's state-of-the-art RFS RADIAFLEX Radiating cable solutions for the 2.4-2.5GHz ISM band often used for signalling, track-to-train or other mission-critical communication solutions.

The radiating waveguide is ideally suited for real-time applications with highest data rate demands as the 5-6GHz ISM band providing a multiple higher useful RF bandwidth than what is available in the currently used 2.4-2.5GHz ISM band. System design as well as capacity planning of an interference-free and stable IEEE 802.11-based wireless communication system becomes a straightforward task, simultaneously allowing future-proof system concepts with regard to capacity upgrades, including IEEE 802.11ac support.

The RADIAFLEX Radiating waveguide provides the best fit 'RF coverage contouring' product, ensuring the lowest signal variations and homogenous coverage, setting new standards for onboard applications.

The new RADIAFLEX Radiating waveguide also underlines the company's leadership in this market segment by simultaneously setting new technological standards. This holistic approach is valuable for customers as an end-to-end solution that is optimised from technology, commercial and cost (capital and operating) perspectives.
