Installation Planning
SITE SELECTION
A network’s performance can be impacted by attributes of the installation site. An
optimal installation provides for:
?? protection from direct exposure to weather
?? power source, both adequate and stable
?? less than 256 radios per channel
?? radios placed within 20 miles of each other
?? line of sight between the Master and each Remote antennas, provides the most
reliable communication link
?? portable Remote radio requirements, maintain a line of sight
?? proximity of massive structures off of which radio signals can bounce, metal
walls
?? sources of RF interference, electrical equipment (arc welding, switching power
supplies, etc.)
?? antennas types
?? cabling losses, signals lose power over cabled distance
Mounting the antenna on a tower or rooftop can provide a line-of-sight path if the site
contains obstructing terrain or structures. The line-of-sight consideration becomes more
important as the transmission path becomes longer. It is most important as the
transmission path approaches the limiting 20 mile specification.
Though radio frequency communication is reliable, sometimes its performance can be
impacted by intangibles. It is suggested that the network installation planning include
time and resources for performance testing and installation changes.
It is suggested that the installation plan be tested before the network is finally installed.
