operation cannot be guaranteed without satisfying all of the four requirements.
C
of any obstacles. It not only means that one has to see the other side, but other
possible sources of disturbance should also be taken into consideration. For
example there might be turbulence above the roofs and other constructions, and this
can cause fraction or scattering of the beam or snow accumulation on roofs too
close to the beam can influence or even interrupt communication.
S
the beam is limited, it is extremely important to mount the unit on a stable structure
with the possible smallest movement. This way the receiver of the remote unit
cannot get out of the beam due to the movement of the opposite head.
E
filters to protect the receiver diode from the effect of undesired light sources, direct
sunshine can cause saturation of the diode. This prevents the system from working
properly for several minutes a day at certain times of the year. In most cases this
effect can be avoided by careful selection of the mounting spot.
In
discussed four key factors and other criteria - the following matters should be taken
into consideration.
