Aspects of Infrared
Distribution
A good digital infrared language distribution system
ensures that all delegates in a conference venue
receive the distributed signals without disturbance.
This is achieved by using a sufficient number of
well- positioned radiators, so that uniform IR signal
with adequate strength can be received at any place
of the conference venue.
When planning an infrared distribution system
several aspects influencing the uniformity and
quality of the infrared signal should be considered.
These are discussed in the next sections.
1.3.1.
Ambient Lighting
Aladdin can be operated without any problem even
if fluorescent lamps (with or without electronic
ballast or dimming facility) such as TL lamps or
energy saving lamps are switched on. (see Figure
1.6 and Figure 1.7).

lighting system (fluorescent lamp)
Figure 1.7: The infrared language distribution system
using BAND IV (2-6MHz) eliminates interference from
high frequency lighting systems
For venues with large, unscreened windows, more
radiators should be added. For outdoor use, a site
test will be required to determine the required
amount of radiators. With sufficient radiators, the
receivers will work well, even in bright sunlight.
