2.2 Number of Sections
When designing a closed perimeter system using volumetric barriers
,
as well as
having to split
the perimeter into a certain number of sections as required by the end user, it must also be
remembered that it is always preferable to install an
even number of sections
. This is desirable
because any reciprocal interference between adjacent sections is cancelled if
two devices of
the same type (two transmitters or two receivers)
are installed at the crossover points of the
polygon that represents the installation. It is evident that this will occur only if the number of
sections is even. Should it not be possible to have an even number of sections then some careful
consideration must be given to interference that might occur in order to find the crossover point
that is the best when positioning the transmitter near the receiver. The following pictures show
some typical cases for which the best solution is given (see figure 1 ).
