Link Microtek sets its sights on mobile local comms at DSEI 2019

Tripling the range of mobile local communucations (MLC), Link Microtek will introduced the latest version of its Azdec optical MLC system at DSEI 2019 in London this month.

The Azdec optical MLC system has a range of up to 30m, opening up new defence-related applications for the Azdec system, which provides secure, non-RF, cable-free communications.

The Azdec 30 system has been optimised for extended-range operation by means of a redesigned communication protocol and reshaped transmission/reception patterns. A typical installation comprises a compact base station, a number of fixed antennae, a choice of headset styles, operators’ belt-mounted battery-pack/control units, and a central battery-charger unit.

It can be used in large hangars or open spaces where RF transmissions might jeopardise security, explains Link Microtec. The Azdec 30 system allows operators to communicate with one another while roaming freely, unhindered by any trailing wires. The extended range of the system means that it could also be used in through-water communications scenarios or for transmitting, say, video from and data to unmanned ground vehicles involved in explosive ordnance disposal.

Originally developed using infra-red technology to provide secure bridge communications on board naval vessels, the Azdec system delivers clear voice communications using micro-LED arrays transmitting at a wavelength determined by the requirements of the specific application. The system carries a Class 1 product designation as defined by the EN 60825-1 standard, which means it presents no ocular or other health hazard to users, confirms Link Microtek.

The system’s optical digital encoding technology is completely immune to radio, radar and electrical noise – even severe energy pulses – and has no effect on sensitive electronic equipment, flammable atmospheres or munitions, says Link Microtek. There are no RF emissions and the signals cannot be intercepted by any conventional method, says the company, so it is impossible for anyone to jam the transmissions or eavesdrop.

Link Microtek will be at DSEI 2019 (ExCel, London, England from 10 to 13 September, Stand S3-435.
