System enables interference-free communications

Designed and manufactured by Link Microtek subsidiary Azdec, the Infra-Com system is said to be particularly suitable for areas of high electrical or acoustic noise and allows operators to speak to each other or to a central base station without using radio signals.

The system's low-level infrared digital encoding technology poses no health hazard even though areas up to 10,000m2 can be covered.

Signals are virtually impossible to detect, according to Link Microtek, and are completely immune to electromagnetic interference - even severe energy pulses.

Providing multi-channel, full-duplex communications, the system comprises a compact base station, a number of fixed infrared antennas, a choice of noise-attenuating or ultra-lightweight headsets, operators' belt-mounted battery packs/control units, and a central battery-charger unit.

All elements of the system are robustly designed for use in demanding environments such as those found on board ships, in submarines, in helicopters or in armoured vehicles.
