Placement of the components

The Wireless Solution uses radio signals for communication. The wireless terminals uses very low output
power (10 mW for 433.92 MHz) and the result is that the range for the terminals is 80 m or less. Obstacles,
interference from other radio sources, etc. usually result in a shorter range, perhaps only 30 m.
Usually you should place the multi interface in the centre of the area where the terminals will be used. This
is very easy if the terminals will be used in one open room.
Place the multi interface as high as possible. The range is reduced if the radio waves must pass through
humans.
If there are obstacles then they must be taken into consideration when you place the multi interface. The
following figures give you some examples.

The terminals can be used in the whole room. The interface is placed in the middle of
the room and usually above the acoustic ceiling. The interface must be placed under
acoustic ceilings made of metal.
