Determine the Maximum Range
The maximum range of your Avaya Wireless Outdoor Router antenna system is
based on the:
■
Type of Outdoor Antenna Equipment (page 3-3)
■
Data Speed of the Wireless Link (page 3-7)
■
Clearance of the Signal Path (see “Determine the Clearance Factor” on
page 3-8).
NOTE:
The values listed in this section are based upon calculations that
assume “optimal radio conditions”.
They do not represent a guarantee that the same maximum distance
can be achieved at your location. Different performance figures may
result from:
■
Incorrect alignment of antennas (see “Antenna Alignment” on
page 2-13).
■
Polarization mismatch of the antennas.
■
Sources of interference or unexpected reflections in the signal path
that affect the communications quality (see “Antenna Placement”
on page 2-9).
■
Severe weather conditions such as heavy rain or snow fall, or
strong winds.
■
Seasonal influences such as leaves on trees, or icing on the
antennas.
Type of Outdoor Antenna Equipment
As described in the previous chapters, Avaya Inc. offers different types of
outdoor antennas, and cable lengths to design your Avaya Wireless
Outdoor Router outdoor antenna installation.
■
The directional antennas provide maximum range, but due to their narrow
signal beam width, these antennas require precise antenna alignment to
achieve optimal performance. The higher the antenna gain the more precise
the alignment should be.
Directional antennas are typically used to connect:
—
Two Remote Outdoor Routers in a Point-to-Point link.
—
One Remote Outdoor Router (satellite) to one Central Outdoor Router
(base) in a Point-to-Multipoint link.
