Outdoor Planning and
Deployment Considerations
Planning and Deployment Considerations
Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a
successful Alcatel-Lucent WLAN deployment. Successfully evaluating the environment enables the
proper selection of Alcatel-Lucent APs and antennas and assists in the determination of their placement
for optimal RF coverage. This process is considered WLAN or RF planning and Alcatel-Lucent’s system
engineers can assist in the outdoor planning process.
Scale Requirements
The potentially immense scale of outdoor deployments requires consideration of factors that may not
be as important in a typical indoor deployment:
z
Range (distance): Range or distance between APs must be taken into account during the planning
phase. Available AP mounting locations are often far less flexible in an outdoor environment.
Regardless of these outdoor restrictions, the desired goal is to achieve results similar to an indoor
deployment: a “dense” RF deployment that supports advanced Alcatel-Lucent features, such as
ARM, efficient client roaming, and failover.
z
Elevation: Proper consideration and planning for elevation differences between APs (AP to AP) and
AP to Client can be critical to success. To plan for these differences in elevation, it is important to
understand the 3D coverage pattern provided by the antennas that will be deployed in the
environment.
z
Non-Fixed Considerations: The RF environment might change on a day to day basis. Keep non-fixed
items, such as shipping containers, vehicles, and future building construction, in mind when
planning for an outdoor deployment.
Identifying Known RF Absorbers/Reflectors/Interferences Sources
Identifying known RF absorbers/reflectors/interference sources while out in the field during the
installation phase is critical. Even though outdoor environments consist of fewer RF absorbers/
reflectors/interference sources compared to indoor environments, ensure that these sources are
identified and taken into consideration when installing and mounting an AP to its fixed outdoor
location.

Line of Sight (Radio Path Planning)
OAW-AP85 Series access points are capable of performing as one of the following:
z
Point-to-point wireless distribution system (WDS) bridge
z
Point-to-multi-point WDS bridge
z
Enterprise mesh point (MP)
z
Enterprise mesh portal (MPP)
To configure the OAW-AP85 as a mesh point or mesh portal, you must install a mesh software
license on a WLAN Switch as a software license key. Contact your sales account manager or
authorized reseller to obtain the software license. There are several mesh software licenses available
that support different maximum number of APs. The licenses are cumulative; each additional license
installed increases the number of APs (mesh nodes) supported by the WLAN Switch.
NOTE
A wireless bridge or mesh link requires a “radio line of sight” between the two antennas for optimum
performance. The concept of radio line of sight involves the area along a link through which the bulk of
the radio signal power travels. This area is known as the first Fresnel Zone of the radio link. For a radio
link, no object (including the ground) must intrude within 60% of the first Fresnel Zone.
Figure 8 illustrates the concept of a good radio line of sight.
Figure 8 Line of Sight
Radio Line of Sight
Visual Line of Sight
If there are obstacles in the radio path, there may still be a radio link but the quality and strength of the
signal will be affected. Calculating the maximum clearance from objects on a path is important as it
directly affects the decision on antenna placement and height. It is especially critical for long-distance
links, where the radio signal could easily be lost.
When planning the radio path for a wireless bridge or mesh link, consider these factors:
z
Avoid any partial line of sight between the antennas.
z
Be cautious of trees or other foliage that may be near the path, or may grow and obstruct the path.
z
Be sure there is enough clearance from buildings and that no building construction may eventually
block the path.
z
For very long distance links, the curvature of the earth (20 cm per km) may need to be considered in
the calculation of relative heights.
16 | Outdoor Planning and Deployment Considerations
Alcatel-Lucent OAW-AP85 Outdoor Access Point Series | Installation Guide
z
Check the topology of the land between the antennas using topographical maps, aerial photos, or
even satellite image data (software packages are available that may include this information for your
area).
z
Avoid a path that may incur temporary blockage due to the movement of cars, trains, or aircraft.
Antenna Height
A reliable wireless bridge or mesh link is usually best achieved by mounting the antennas at each end
high enough for a clear radio line of sight between them. The minimum height required depends on the
distance of the link, obstacles that may be in the path, topology of the terrain, and the curvature of the
earth (for links over 3 miles).
For long-distance links, the AP may have to be mounted on masts or poles that are tall enough to attain
the minimum required clearance. Use the following table to estimate the required minimum clearance
above the ground or path obstruction (for 5 GHz bridge links).

To avoid any obstruction along the path, the height of the object must be added to the minimum
clearance required for a clear radio line of sight. Consider the following simple example, illustrated in
the figure below.

A wireless bridge or mesh link is deployed to connect building A to building B, which is located three
miles (4.8 km) away. Mid-way between the two buildings is a small tree-covered hill. From the above
table it can be seen that for a three-mile link, the object clearance required at the mid-point is 5.3 m
(17.4 ft). The tree tops on the hill are at an elevation of 17 m (56 ft), so the antennas at each end of the
link need to be at least 22.3 m (73 ft) high. Building A is six stories high, or 20 m (66 ft), so a 2.3 m
(7.5 ft) mast or pole must be constructed on its roof to achieve the required antenna height. Building B
is only three stories high, or 9 m (30 ft), but is located at an elevation that is 12 m (39 ft) higher than
building A. To mount an antenna at the required height on building B, a mast or pole of 1.3 m (4.3 ft) is
needed.
!
Never construct a radio mast, pole, or tower near overhead power lines.
CAUTION
Local regulations may limit or prevent construction of a high radio mast or tower. If your wireless
bridge or mesh link requires a high radio mast or tower, consult a professional contractor for advice.
NOTE
Antenna Position and Orientation
Once the required antenna height has been determined, other factors affecting the precise position of
the wireless bridge or mesh link must be considered:
z
Be sure there are no other radio antennas within 2 m (6 ft) of the wireless bridge or mesh link. These
include other WiFi radio antennas.
z
Place the wireless bridge or mesh link away from power and telephone lines.
z
Avoid placing the wireless bridge or mesh link too close to any metallic reflective surfaces, such as
roof-installed air-conditioning equipment, tinted windows, wire fences, or water pipes. Ensure that
there is at least 5 feet clearance from such objects.
z
The wireless bridge or mesh link antennas at both ends of the link must be positioned with the same
polarization direction, either horizontal or vertical. Proper alignment helps to maximize throughput.

Alcatel-Lucent OAW-AP85 Outdoor Access Point Series | Installation Guide
Radio Interference
The avoidance of radio interference is an important part of wireless link planning. Interference is
caused by other radio transmissions using the same or an adjacent channel frequency. You should first
scan your proposed site using a spectrum analyzer to determine if there are any strong radio signals
using the 802.11a/b/g channel frequencies. Always use a channel frequency that is furthest away from
another signal.
If radio interference is still a problem with your wireless bridge or mesh link, changing the antenna
direction may improve the situation.
Weather Conditions
When planning wireless bridge or mesh links, you must take into account any extreme weather
conditions that are known to affect your location. Consider these factors:
z
Temperature: The wireless bridge or mesh link is tested for normal operation in temperatures from
-. Operating in temperatures outside of this range may cause the unit to fail.
z
Wind Velocity: The wireless bridge or mesh link can operate in winds up to . You must consider the
known maximum wind velocity and direction at the site and be sure that any supporting structure,
such as a pole, mast, or tower, is built to withstand this force.
z
Lightning: Rain: The wireless bridge or mesh link is weatherproofed against rain. However, it is
An Alcatel-Lucent Lightning Arrestor, AP-LAR-1, must be installed on each antenna port for
protection against lightning induced surges. Failure to use an AP-LAR-1 can void the warranty of an
Alcatel-Lucent outdoor AP model and renders the AP susceptible to failure from lightning induced
surges.
!
CAUTION
recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors
for extra protection. If moisture enters a connector, it may cause a degradation in performance or
even a complete failure of the link.
z
Snow and Ice: Falling snow, like rain, has no significant effect on the radio signal. However, a
buildup of snow or ice on antennas may cause the link to fail. In this case, the snow or ice has to be
cleared from the antennas to restore operation of the link.
Ethernet Cabling
When a suitable antenna location has been determined, you must plan a cable route from the wireless
bridge or mesh link outdoors to a suitable power and/or network source.
Consider these points:
z
The Ethernet cable length should never be longer than 90 m (295 ft).
z
Determine a building entry point for the cable (if applicable).
z
Determine if conduits, bracing, or other structures are required for safety or protection of the cable.
z
For lightning protection at the power injector end of the cable, consider using a lightning arrestor
immediately before the cable enters the building.
Grounding
It is important that the wireless bridge or mesh link, cables, and any supporting structures are properly
grounded. Each OAW-AP85 Series access point includes a grounding screw for attaching a ground wire.
Be sure that grounding is available and that it meets local and national electrical codes.

Before you can select the antenna type needed for the deployment, read the basic wireless antenna
information provided in this section. This information will help you understand wireless antenna basics
and Alcatel-Lucent antenna specifications.
Understanding Wireless Antennas
Omni-Directional vs. Directional Coverage
For optimal performance of your wireless network, it is essential to understand the purpose behind
proper antenna selection. Choosing the correct antenna type will ensure that RF energy is being
directed to the correct coverage areas. Omni-directional antennas provide equal coverage in all
directions (see Figure 22), while directional antennas point RF energy in a specific direction for RF
concentration within a targeted area (see Figure 23).

Antenna Beamwidth, Pattern, and Gain Considerations
Antenna gain is a relative measure of how the antenna compares to an ideal isotropic radiator. An ideal,
isotropic radiator would radiate power in all directions equally over a sphere. The relationship between
gain, power, and propagation distance is detailed already in textbooks and Wiki's, so these expressions
are not repeated here. Antenna gain is often confused with power gain in amplifiers, but it is important
to note that antenna gain only makes a transmitter's power appear to be higher than would be predicted
by calculation of the power fed to the antenna and then spread equally over a sphere. Antenna gain
itself is a completely passive and bi-directional property, determined only by the shape and
construction of the antenna.
Knowing that gain is only a comparison of the apparent power to the power that would be required if
fed to an ideal isotropic antenna, you realize that gain can only be created by distorting the antenna
pattern from the ideal spherical pattern. Think of this as focusing the same power that would normally
distribute evenly over a sphere into a tighter region of space. Thus, the higher the gain, the more
concentrated (in some way) the antenna pattern must be in order to achieve that gain.
Example
To visualize the concept of gain, picture a rubber ball. The surface area of the ball represents the total
available power radiated by an ideal isotropic antenna over its sphere of radiation (see Figure 24).
Figure 24 Equal Signal Strength Radiated in All Directions
Equal Signal Strength
Radiated over a Sphere
32 | Understanding Antennas
Alcatel-Lucent OAW-AP85 Outdoor Access Point Series | Installation Guide
Now, still using the same ball with the same available surface area, how would you be able to stretch
the ball farther out? One way is to press down on the top of the ball and squash it down vertically. This
would keep the same basic shape in the horizontal plane (round), but it would force the ball to stretch,
creating a pancake shape, in the vertical direction (see Figure 25). This represents the concept of the
high gain omni-directional antenna, which achieves a greater coverage distance in the horizontal
direction at the expense of coverage in the vertical areas of the radiating sphere.
Figure 25 High Gain Omni-Directional Antenna
High Gain
Omni-Directional Antenna
Compressed vertical signal,
which expands signal
horizontally
To stretch the ball primarily in one direction (instead of in all directions), push the ball, both vertically
and horizontally, on the sides and on the back, to force the ball to deform in a single direction. This
action would significantly distort the shape of the original ball both horizontally and vertically, but it
will allow you to stretch the same ball a lot farther in one direction (see Figure 26). This represents the
concept of the high gain directional antenna, which is designed to compress the entire radiating sphere
into a single predominate direction.
NOTE
Gain is created by forcing transmitted power to radiate in a preferred direction rather than radiating
in all directions of an ideal sphere. Therefore, a high gain signal is always accompanied by loss of
available signal in some other portion of the ideal sphere. High gain directional antennas are ideal for
sites requiring directed coverage in a specific area or extended range for bridging applications, but
they are not suited for sites requiring uniform coverage in large areas. It is important to keep in mind
that both vertical and horizontal coverage can be affected by the use of a higher gain antenna and
beamwidth (a measure of coverage) is always inversely related to gain.

Understanding Antenna Pattern Plots and Specifications
Traditional 2-D pattern plots and beamwidth specifications are like mental puzzles waiting to be solved
because they only provide a snapshot of the information in two planes. These two planes are often
referred to as the azimuth (H-plane or horizontal) and elevation (vertical or E-plane) planes. The
azimuth view would be considered the view from directly above, viewing the antenna pattern on the
horizontal plane. The elevation view is considered to be a side view, viewing the antenna pattern on the
vertical plane. It is helpful to think of these planes as “cuts” of the real antenna pattern, which is
actually 3-D. Figure 27 illustrates where these “cuts” are located for a typical omni-directional antenna
pattern.
Figure 27 Antenna Pattern Conventions (Omni-Directional Pattern Shown)
Elevation, E-plane,
or Vertical Pattern
Diagram
Azimuth, H-plane,
or Horizontal
Pattern Diagram
The antenna illustrated by Figure 27 is commonly referred to as the dipole pattern because it is the
pattern produced by an ideal dipole antenna. The gain of this antenna is 2.14, which is achieved by
compression in the vertical plane (elevation) compared to the ideal sphere. If referring to the true 3D
pattern, this compression is sometimes called the donut shape (see Figure 28).
Figure 28 Donut Shape Compression of an Omni-Directional Antenna
34 | Understanding Antennas
Alcatel-Lucent OAW-AP85 Outdoor Access Point Series | Installation Guide
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 Alcatel-Lucent’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 Alcatel-Lucent’s detachable antenna offerings.
Terminology and degree of sector in Alcatel-Lucent’s antenna specifications are determined by the
horizontal 3 dB beamwidth.
z
Down-Tilt: An omni-directional antenna that focuses its energy downwards.
z
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).
z
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
z
If omni-directional coverage is desired with the greatest possible horizontal range from the AP,
select one of Alcatel-Lucent'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.
z
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.
z
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.
Alcatel-Lucent OAW-AP85 Outdoor Access Point Series | Installation Guide
Understanding Antennas | 35
Figure 29 AP-ANT-90 E-Plane View (Side View)
Figure 30 AP-ANT-90 H-Plane View (Top View)
z
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.
z
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).
z
Directional antennas are selected to focus RF energy more efficiently to a targeted area.
z
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
36 | Understanding Antennas
Alcatel-Lucent OAW-AP85 Outdoor Access Point Series | Installation Guide
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.
