3.4.1.4 Make each conference unit communicating
with more than one transceiver
As shown in the following figure: when the speaker in the
front row speaks in an upright position, the infrared
signal will be blocked. In conference rooms with
conference units in rows, each conference unit should
communicate with more than one transceiver to avoid
blocking.
Figure 3.7 Infrared signals blocking
So, each transmitter should communicate with more than
one receiver to avoid blocking.
3.4.1.5 Stay away from plasma displays
When planning an infrared wireless discussion system,
plasma displays are not appropriate to be used in the
venue. If you want to use plasma displays, infrared
wireless conference units and infrared wireless
transceivers/receivers should not be used closer than 3
meters to the plasma, or the plasma display should be
equipped with an infrared filter.
