Infrared used for voice comms
Link Microtek, the Basingstoke-based microwave specialist, has introduced an 8-channel infra-red communications system for secure short-range voice communications.
Called Azdec, system consists of a basestation, a number of fixed infra-red antennas and headsets.
The 8-channel configuration allows up to eight completely independent conversations to take place simultaneously, with operators either speaking to each other or linking into a central communications system via the Azdec basestation.
Using the optional split-ear facility, an operator can even listen to different channels on each side of the headset, which could be a particularly important feature in an ATC (air traffic control) environment.
Other suitable applications include naval short-range communications and high-security control rooms.
