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.
Since infra-red radiation can reach a receiver

Positioning the radiators

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 3.3-G and Figure 3.3-H).

situated clear from obstacles and walls, so a
combination of direct and diffused radiation can
be received. Figure 3.3-J shows the signal being
reflected from a number of surfaces to the
participant.
