The digitally
encoded infra red is used as the media to transmit the encoded voice signals to
and from the mobile user within the vehicle where there is both sensitive and
electrically noisy equipment. The user gains complete freedom of movement while
maintaining crystal clear two way voice communications.
The sensitive equipment is vulnerable to radio transmissions while the noise
generated by the high current electronics can cause interference to
communications channels. Digitally encoded infra red will not effect the most
sensitive of electronic equipment and is totally immune to high levels of
electrical noise. This makes infra red the ideal media for wire free voice
communications in modern vehicles and in test cells.
