It is evident from Figure 27 that 2-D pattern plots typically provided in antenna specifications are a
simplification of the real 3-D situation. Often, 2-D plots are reduced even further to a set of simple
specifications based on the antenna gain and 3 dB beamwidth.
Detachable Antenna Selection
Select the correct antenna type to support the required frequency band (2.4 GHz or 5 GHz) and desired
coverage pattern.
To select the correct antenna type for the deployment, download and read Aruba’s outdoor antenna
specifications: http://www.arubanetworks.com/products/access-points/antennas.php.
All figures are shown with a 100 meter (328 feet) mounting height above the ground and for a
18 Mbps coverage area.
NOTE
Detachable Outdoor Antenna Types
These are some of the terms used to describe Aruba’s detachable antenna offerings. Terminology and
degree of sector in Aruba’s antenna specifications are determined by the horizontal 3 dB beamwidth.
Down-Tilt: An omni-directional antenna that focuses its energy downwards.
Sector/Patch: A directional antenna that provides a focused sector of coverage from a central point
(Example: +/- 45 degrees from a 90 degree center point).
Panel: A flat formed antenna that directs energy to a sector of coverage. This type of antenna is often
ideal for point-to-point WDS bridging or wireless mesh backhaul applications.
Detachable Antenna Selection Tips
If omni-directional coverage is desired with the greatest possible horizontal range from the AP,
select one of Aruba's detachable antennas with high-gain, omni-directional coverage. Due to the
tight vertical beamwidth of high-gain, omni-directional antennas, this typically requires mounting
the antenna not more than 5 meters (16.5 feet) above the expected client locations in elevation.
If omni-directional coverage is desired, but only high mounting locations are available
(approx. 5 m (16.5 feet) to 10 m (33 feet), consider the use of lower gain (3 dBi to 5 dBi) omnidirectional antennas and a denser AP deployment. The lower gain antenna will reduce the maximum
horizontal range of the AP, but will provide better vertical coverage.
For very high mounting locations (>10 m/33 feet) such as light poles or monopoles, consider the use
of an omni-directional antenna with electrical downtilt. A downtilt omni-directional antenna is an
antennas that has a direction of maximum gain at approximately 45° down from horizontal.

Figure 30 AP-ANT-90 H-Plane View (Top View)
Alternatively, for high mounting locations, high-gain sector antennas may be used with mechanical
downtilt. This will typically require the use of multiple access points per mounting location to
provide omni-directional coverage.
If a directional antenna is required to direct RF coverage, the detachable antenna must be capable of
supporting all of the frequency bands that require support (2.4 GHz and/or 5 GHz).
Directional antennas are selected to focus RF energy more efficiently to a targeted area.
Directional antennas are also useful in areas where the surrounding materials have high amounts of
RF attenuation or reflection and the RF signal needs to be guided in the direction of the least

amount of attenuation or reflection. For example, when mounting antennas on the outside surfaces
of a building to provide coverage to outdoor spaces in front of the building, a directional antenna
can be used to direct the coverage away from the building.
High Mounting Omni-Directional Antenna Scenario (AP-ANT-80 vs. AP-ANT-90)
The AP-ANT-80 shows greater horizontal range due to its higher gain (8 dBi vs. 3 dBi) antenna, but in
this very high mounting situation, the AP-ANT-90 may be a better choice for ground level coverage
because the direction of maximum gain is directed downward toward the ground. This situation could
potentially be improved if a lower mounting elevation was available for the AP-ANT-80, ideally about
5 m above Ground.

High Mounting Directional Antenna Scenario
The AP-ANT-82 is a high gain (12 dBi), directional antenna with a 90 degree 3 dB beamwidth in azimuth.
For this high mounting condition, this antenna provides a long range in the direction of maximum gain,
but it would require mechanical downtilt for ground level coverage.
