Determine the Outdoor Range
3
The range of your outdoor antenna installation is closely related to
a number of different factors. To allow you to determine the range
of the WaveACCESS Office Router antenna system in your
situation, we have defined the formula listed below:
Range = Maximum Range x Cable Factor x Clearance Factor
■
Maximum Range
identifies the theoretical maximum that could
be achieved under optimal circumstances using the available
WaveLAN Outdoor products according to their specs and in
compliance with local radio regulations.
This value can be read from Table 3-1 or Table 3-2, according
to the country where the antenna system will be installed.
■
Cable Factor
identifies a corrective percentage value that
compensates additional cable loss in case you are using
different cable lengths. The Cable Factor value can be read
from Figure 3-1 on page 3-9.
■
Clearance Factor
identifies a corrective percentage value that
should be applied in case the signal path of your wireless link
does not provide the minimum clearance listed in the
Maximum Range table. The Clearance Factor can be read
from Figure 3-3 on page 3-12.
An example on how to use this formula is described on page 3-13.
!
CAUTION:
This formula should only be used as a rule of thumb to
asses the possible range that could be achieved in your
situation, and/or to select the type and height of the
antenna installations. Always perform on-site
measurements to validate the results from the range
calculation. To perform such measurements you can use
the WaveMANAGER/OR Wireless Link test option as
described in the WaveMANAGER/OR User’s Guide.
