Protection for critical systems

Fitelnet is a specialist in protecting sensitive electronic systems against electromagnetic pulses and designing, building, and maintaining radio and telecommunication networks, as well as product development and electrical assembly.

Essential electronic equipment – especially that used by defence forces and the authorities – needs to be protected against the threat posed by electromagnetic pulses (EMP) resulting from electromagnetic interference, high-power microwave (HPM) weapons, or high-altitude nuclear detonations. Unprotected electronic equipment or components can be damaged or destroyed by the voltage surges that result from these pulses.

Fitelnet’s goal is to offer a high level of EMP protection and ensure that critical information and communication systems remain operational.

Guaranteed protection

Fitelnet’s system cabinets have been designed to provide just this protection. The company’s EMP/HPM-protected cabinets offer excellent attenuation up to 18 GHz and feature stainless steel for strength, durability, and low weight.

A Fitelnet cabinet – used as part of a fixed system or integrated into vehicles and/or containers – can provide EMP/MPM protection for a variety of equipment, enabling platforms to operate in a wide range of environments. Individual solutions are closely tailored to customers’ specific requirements.

Interfaces and connectors are EMP-protected and supplied to customer specifications. Fitelnet’s advanced FAPS-8 filter is the most effective unit of its type on the market today. Primarily designed for 2 Mbit/s transmission lines, the FAPS-8 provides a high level of protection against lightning, EMP, and highpower microwaves, and is easy to install and connect.

Systems used by defence forces and official agencies need effective protection against EMP to ensure that they can remain operational in even highly challenging environments.

To give copper wire-based local area network (LAN) connections used for transferring critical data EMP/HPM protection, Fitelnet offers its unique FAPS- 100 filter. Designed for 10/100BaseT interfaces in EMP/HPM-secure cabinets and rooms, the FAPS-100 can protect connections running at up to 100 Mbit/s.

Fitelnet also supplies system shelters and trailers for crisis management operations, providing all the features required by military and official organisations when operating out in the field while giving access to an EMP/HPMprotected platform. Shelters and trailers can include splinter and bullet protection, energy generation units, temperature and humidity control technology, shock absorbing systems, masts, and other capabilities.

A TETRA expert

In addition to EMP/HPM products, Fitelnet is also an expert in TETRA technology. This includes the TTBS or TETRA Traveller Base Station, a compact, mobile twin-carrier unit that can be easily mounted on vehicles or in containers; an EMPprotected version can also be supplied.

Fitelnet has provided TETRA indoor coverage planning services for a number of demanding sites in the Middle East, incorporating some highly innovative and advanced solutions. Other sites to have benefited from Fitelnet’s planning expertise range from shopping centres and power plants to tunnels and towers.
