Introducing Critical Communication Solutions by BHE

When reliable communication is crucial, signal stability is essential. In environments where interruption is not an option – such as tunnels, offshore platforms, power plants, or public safety networks – consistent radio coverage is vital for smooth operations.

That is where we come in.

Expanding Communication Coverage

With a 25-year heritage in critical communication RF engineering, we have specialized in custom-built repeater systems that ensure signal integrity in high-demand, low-tolerance locations.

Whether it is FM/DAB, TETRA, DMR or LTE we provide signal continuity in infrastructure where stable coverage is a non-negotiable.

Typical deployment areas

Where Communication Cannot Fail

We design and deliver repeater solutions for complex and mission-critical locations, tailored to operational needs, frequency bands, and physical infrastructure.

Metro, Railway & Road tunnels

From Berlin to Budapest, our single and dual-band repeaters — optically redundant or non-redundant — ensure stable coverage in complex underground environments. Berlin’s metro system features over 150 dual-band repeaters with high MTBF and proven customer satisfaction.

Airports & Transport Hubs

Airports like Schiphol (AMS) and King Khalid (RUH) rely on us for multi-band coverage, including VHF, FM, and TETRA, supporting both security and operational communications.

In-Building Coverage

Skyscrapers, hospitals, stadiums, prisons, warehouses, factories, mines, we support indoor coverage with compact repeaters and scalable DAS architectures, combined with passive RF distribution components when needed.

Wind Farms & Energy Facilities

From the European largest Hornsea 02 offshore wind farm to refineries and nuclear plants, we deliver reliable, ATEX-compliant radio coverage in complex, high-risk environments.

Public Safety & Emergency Services

We support national security service networks with TETRA repeaters designed for seamless operation, including deployments in law enforcement, fire, and medical infrastructure.

Critical Communication Solutions

Repeaters that Match the Mission

Our core expertise lies in designing, producing, and delivering repeater systems for critical communication — analogue and digital, off-air and optical systems. We cover frequencies from 88 MHz to 2.6 GHz, including:

TETRA, LTE and FM/DAB repeaters
Off-air repeaters: both analogue and Software Defined Radio (SDR) based digital
Redundant and/or dual band optical repeater systems (master-remote) for long-distance tunnel and indoor coverage
Modular housing: rack-mount or wall-mount, indoor, IP65 outdoor and ATEX-certified enclosures
Centralized monitoring and control (M&C) via SNMP and NMS

Whether you need a single-site solution or a nationwide deployment, our extensive portfolio offers the right solution for your needs.

Passive Components

Although repeater systems are our core competence, we also provide passive RF components to support coverage expansion and distribution:

Splitters, combiners, couplers, filters, duplexers, diplexers
Designed for harsh environments and tested for reliability

Customizable by frequency band, port count, insertion loss, and isolation.

Thanks to the dynamic and responsive BHE team, together, we bring complex system solutions to life with exceptional flexibility and state of the art designs delivered in impressively short timeframes. For mobile and airborne applications, we specialise in highly compact, efficient and fully customised system designs such as advanced SAR solutions that keep you ahead of the competition.

We have been resellers for BHE Tetra repeaters since 2015 and have won numerous Public Safety Network repeater tenders. The products have consistently delivered exceptional reliability and performance, thus benchmarking them as the de-facto standard in our market. Our customers and us enjoy our co-operation with BHE and their dedication to innovation is evident in every aspect of their work.

One of the longest tunnels in Switzerland, the Vereina tunnel, has been equipped with a BHE broadcast and safety radio repeater system for 5 years. There was not a single interruption in the tunnel supply over the entire service life. We really appreciate the long-standing partnership with BHE. Thanks to the experienced and committed team, large projects can be implemented in a short time. With BHE products we can meet the highest customer requirements.
