RFS is a leader in wireless infrastructure with seven major product sectors (see below).

TRANSMISSION LINES

RFS manufactures a comprehensive range of transmission line products used worldwide for antenna feeders, cabling of antenna arrays, radio equipment interconnections, jumper assemblies and indoor applications.

Products include: HELIFLEX® air-dielectric feeder cables, combining excellent electrical characteristics with robust mechanical performance; and CELLFLEX® aluminium and copper foam-dielectric cables, providing a reliable backbone for cellular radio systems, from GSM and CDMA to UMTS.

BASE STATION ANTENNA SYSTEMS

RFS provides state-of-the-art base station antenna solutions, covering different footprints, patterns, gains and tilt types, to suit all mobile standards in all frequency bands. Whether it be for a green field player or existing operator, RFS has the widest range of 2G (GSM/TDMA/CDMA) and 3G (UMTS/cdma2000) antenna solutions for network deployment.

For high density and urban areas, antenna configurations are available for both space diversity and polarization diversity applications. RFS has a complete range of antenna down tilt options for network optimization: from adjustable mechanical tilt to Remote Tilt™ electrical tilt technology.

Complementing its antenna range, RFS offers complete end-to-end base station RF solutions. Innovative products are combined with superior customer service to provide solutions for network coverage, capacity and infrastructure sharing.

MICROWAVE ANTENNA SYSTEMS

The range of RFS microwave antennas is the most comprehensive in the industry, available in all common frequency bands up to 40GHz. The range includes: heavy-duty grid antennas; WLL, LMDS and MMDS broadband wireless antennas; and the cost-effective CompactLine® and SlimLine® antennas, suitable for the needs of mobile operators.

In support of the microwave antenna systems, RFS FLEXWELL® corrugated elliptical waveguides ensure the highest quality transmission line for microwave communications.

RF CONDITIONING

A leader in the supply of RF conditioning products to OEMs and wireless carriers, RFS offers a comprehensive portfolio of advanced RF technologies at a world-class level of expertise.

The product range comprises: combiners that incorporate manual tune and autotune technologies, filters, receiver multicouplers, duplexers and low noise amplifiers, including tower-mounted amplifiers for 3G applications. Additional products include integrated power monitoring and alarm modules for telecommunications.

WIRELESS DISTRIBUTED COMMUNICATION SYSTEMS (WDCS)

RFS has an extensive range of solutions designed to meet all confined coverage RF needs. Applications consist of in-building mobile communication and wireless networks, tunnel mobile communication, as well as trains, sea vessels, offshore platforms and mines.

The RFS WDCS product suite comprises both active and passive RF network components, from bi-directional amplifiers and fibre-optic links to combiners and antennas. In particular, RFS has two distinct passive distributed communications system topologies: radiating cable, based on RFS's leading RADIAFLEX® range; and distributed antenna systems, using a network of distributed 'point source' antennas.

BROADCAST AND HF SYSTEMS

RFS manufactures a full range of antenna systems for analogue and digital television (DTV), FM radio and DAB applications, as well as HF antennas for military, government and communication applications. Antenna patterns can be tailored to meet any coverage requirement and to suit requirements for towers, mounting arrangements and environmental conditions.

In addition, RFS specialises in combining solutions that allow broadcasters to maximize value from their broadband antenna systems investment. RFS is a pioneer in the development of adjacent channel combining for the addition of DTV services.

TOWERS

CGTI Pylônes is a tower and mast specialist within the RFS group; they provide total tower solutions for mobile communications, television, radio, microwave and backbone transmissions, measurement instruments and radar, throughout Europe, the Middle East and Africa.
