Step Three: Perform a Site Survey
In this step, you assess the Line of Sight and RF environmental factors.
Check for the existence of competing RF signals, using a spectrum analyzer.
Detect and measure the potential sources of interference in selected RF bands
for each site
Mark the direction and nature of detected RF interference on the wireless net-
work map (created in step two).
Determine the height of obstacles (trees, buildings, highways) in each link’s
path.
Step Four: Finalize the Design
The final step includes adjusting your plan and selecting equipment.
Adopt changes in the network layout to overcome RF interference, and to
guarantee the minimum required bandwidth for each link.
Adjust antenna height requirements based on identified obstacles in the site
survey.
Select the antenna types for each site, based on the link distance and minimum
antenna co-location requirements.
Select an RF channel and antenna polarity plan for each link.
Select cable types and lengths.
