3.1.1.1 Key factors of operation
There are four key issues that the site survey has to shed light on. The proper
system operation cannot be guaranteed without satisfying all the four
requirements.
?
Clear line of sight - first of the entire optical path between the two ends
must be free 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 the communication.
?
Solid mount surface - is the key for long-term operation. Since the
diameter of 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.
