Positioning The Radiators - Bosch Integrus Installation And Operation Manual

Problems caused by shadows from walls or furniture can be solved by ensuring that there are
sufficient radiators and that they are well positioned, so that a strong enough infra-red field is
produced over the whole conference area. Care should be taken not to direct radiators
towards uncovered windows, as most of this radiation will subsequently be lost.

Positioning the radiators

Since infra-red radiation can reach a receiver directly and/or via diffused reflections, it is
important to take this into account when considering the positioning of the radiators. Though
it is best if receivers pick up direct path infra-red radiation, reflections improve the signal
reception and should therefore not be minimized. Radiators should be positioned high enough
not to be blocked by people in the hall (see Figure 4.10 and Figure 4.11).

The figures below illustrate how infra-red radiation can be directed to conference
participants. In Figure 4.12, the participant is situated clear from obstacles and walls, so a
combination of direct and diffused radiation can be received. Figure 4.13 shows the signal
being reflected from a number of surfaces to the participant.
