7 Sites of installation
7.1 Key factors of operation
There are four key issues that the site survey has to shed light on. Proper system
operation cannot be guaranteed without satisfying all of the four requirements.
Clear line of sight
- 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 communication.
