10 Installing on site
Once you are happy with the basic Host and Client(s) set up as described above the
units can be installed on site. It is recommended that all units are set up prior to
installation on site although frequencies may need to be adjusted if they have been
manually set if there is interference on certain channels. See Section 11.2.6.1
Interference Analyzer for instructions of how to carry out a frequency site survey using
the ‘Interference Analyzer’ tool on a Host unit to determine frequencies already in use on
a site.
10.1 Line-of-sight
It is important that there is proper line-of-sight between each Host and associated
Client(s). Line-of-sight is NOT just a single clear view running between the two points
like a laser beam. Line-of-sight includes the Fresnel Zone; think of being able to drive a
double decker bus between the two points without anything being in its path. If trees or
any other obstacle are blocking part of the Fresnel zone, the wireless system may not
transmit the signal the required distance.
In a situation like this, the transmit and receive antennas need to be mounted on higher
poles to get above the trees.
