Positioning the Radiators
Because infrared radiation can reach a receiver
directly and / or via diffused reflections, it is
important to take this into consideration when
installing the radiators. For best reception quality,
receivers should pick up direct infrared radiation. In
addition reflections will improve the signal
reception. In big conference halls, infrared signal
will be blocked by the people in front of the
receiver. For that reason the radiator should be
installed at an appropriate height, usually not below
2.5 meters.
For concentrically arranged conference venues,
radiators located high up and faced to the center
from every angle can cover the area very efficiently.
If the direction of the receiver changes, e.g.
changing seat direction, the radiators can be
installed in the corners of the room.
In the case the seating is always directed towards
the IR emitting source, there are no radiators
needed at the back (see Figure 1.12).

with auditorium seating and podium
If the path of the infrared signals is blocked, e.g.
under balconies, at least one additional radiator is
needed to cover the ‘shaded’ area (see Figure 1.13).
