Radio Frequency Systems - The partner of choice

Transportation operators' communications must ensure high quality across tunnels, in-building and outdoor contexts. Radio Frequency Systems provides solutions that support commercial applications, increase passenger satisfaction and provide new revenue opportunities

For more than 40 years, Radio Frequency Systems (RFS) has provided innovative communications solutions for the world's metros, railways, road tunnels, mines, ships and airports. Today, RFS 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.

Best-in-class technology

RFS's best-in-class communications technology for the transportation market is LTE-ready. Transportation operators can benefit from its technology advantages today, confident in the knowledge that they are able to evolve to LTE when the timing is right for their business - without requiring the purchase of additional equipment.

RFS's RADIAFLEX suite of radiating cables showcases its 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.

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.

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.

Features include:

  • 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, meeting 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 1/2-1 5/8in, RADIAFLEX cables are available with different jacketing, coupling losses and bending radii.

Ideal for confined-coverage applications

RADIAFLEX cables support a wide range of applications, including:

  • wireless telephony (analogue, 2G/3G, 4G digital including LTE, TETRA and GSM-R)
  • mission-critical communications
  • trunked radio
  • AM and FM radio and television
  • DAB and DVB services.

The unique RADIAFLEX RE60 radiating waveguide (RW) is the leading solution for in-tunnel wireless applications in the 5-6GHz band, allowing for superior system performance and ensuring low insertion-loss and excellent coupling-loss equivalent to today's state-of-the-art RFS RADIAFLEX radiating cable solutions for the 2.4-2.5GHz ISM band, commonly used for signalling, track-to-train or other mission-critical communication solutions.

The RW is ideal for real-time applications, with highest data rate demands at the 5-6GHz ISM band, providing a multiple higher RF bandwidth than 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 straightforward and allows for future-proof system concepts for capacity upgrades, including IEEE 802.11ac support.

The RADIAFLEX RW provides the best-fit RF coverage contouring product ensuring lowest signal variations and homogenous coverage, setting new standards for onboard applications and underlining RFS's leadership in this market segment. 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.
