From these diagrams it can be seen that at each location there is only like kind backhaul modules.
In all cases where there is a cluster management module an access point cluster could be placed
also. In the case of
Example 2 , a cluster management module could be placed where the two
backhaul timing slaves are located to install an access point cluster; however the timing slaves do
not need to be connected to he CMM for timing purposes.
SITE SELECTION CRITERIA
There are various issues that need to be taken into consideration when choosing a location for
the network infrastructure. The following is a list of those considerations. There may be others
as each site is unique.
• Height is essential when installing a Canopy backhaul module. The Canopy backhaul
module must be mounted higher than other objects located immediately around it such as
trees, buildings, tower legs, etc.
• There should be no obstructions that will interfere with the unit’s internal antenna. The area
immediately in front of an access point module must be clear of all obstructions.
• Will the installation area change in the future? Will there be structures high enough to
interfere with the signal? Will trees grow into the line-of-sight path?
• When possible, avoid high RF energy sites. Do not place Canopy equipment in the same
plane as other RF equipment.
• The means used by the installer to attach the backhaul module to the tower, rooftop, or pole
should be rigid and should not move or flex due to wind or other vibrations.
• Tower availability…will a tower have to erected?
• There must be grounding systems available for protection of the Canopy equipment.
• Lighting arrestors are required in installation area to transport lightning strikes away from
equipment.
