Radio Frequency Systems

What Radio Frequency Systems does

Radio Frequency Systems (RFS), headquartered in Hannover, Germany and operating as a privately held GmbH, is a global designer and manufacturer of cable, antenna, and RF conditioning systems for wireless infrastructure. The company traces its origins to 1900, giving it more than 120 years of manufacturing heritage anchored at its Hannover production facility, with a second manufacturing site in Suzhou, China. Its core product portfolio spans HYBRIFLEX hybrid optical fiber and power cables, CELLFLEX low-loss foam dielectric RF feeder cables, RF Jumpers, RADIAFLEX radiating cables (functioning as distributed antennas for tunnels, mines, and underground spaces), HELIFLEX high-power air dielectric cables, FLEXWELL waveguides, and a full line of passive indoor RF components (splitters, couplers, combiners, antennas). RFS integrates these into solution architectures including Distributed Antenna Systems (DAS), Distributed Radio Systems (DRS), and Urban Based Infrastructure (UBI), and maintains proprietary fire-safety brands such as DragonSkin (UL 2196-certified) and RADIAFLEX with the highest CPR rating (B2ca s1a d0 a1).

RFS serves customers across mission-critical verticals including metro/rail, mining, oil and gas/renewables, airports, broadcast, defense, manufacturing (e.g., semiconductor fabs), data centers, stadiums, and government/emergency services. Named reference customers include TSMC, George Bush Airport, UK Fire Services, Australian Defense, Italian hydroelectric operators, Hong Kong transport operators, and the Wertachtal transmitter site (operational since 1972). The company states presence in more than 51% of global metro deployments and serves a combined daily ridership of over 134 million passengers.

The business model is hardware-centric: RFS generates revenue primarily through direct sales of physical connectivity products via regional field sales offices (Hannover, Hong Kong, Dubai, and others), a global network of authorized distributors across 25+ countries, OEM and system integrator partnerships (notably with Nokia for private 5G), and a direct-to-customer e-commerce storefront (RFStore). Pricing is project- and volume-based with no public disclosure. The company operates subsidiary entities in the UK, China (Shanghai and Suzhou), and Singapore, holds ISO 9001/14001/45001/14064 certifications, and is led by President & CEO Monika Maurer and Managing Director Dr. Ekkehard Schomburg.
