dark grey area in figure 1.8 to figure 1.10). In this area,
the direct signal is strong enough to ensure proper
reception when the receiver is directed towards the
radiator.
The size and position of the footprint depends on the
mounting height and the angle of the radiator.

1.3.5 Positioning the radiators
Because infrared radiation can reach a receiver directly
and/or via diffused reflections, it’s 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 of the seating is always directed towards
the IR emitting source, there are no radiators needed at
the back (see figure 1.11).
