Installation Guide Chapter 2 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 Aruba WLAN deployment. Successfully evaluating the environment enables the proper selection of Aruba APs and antennas and assists in the determination of their placement for optimal RF coverage. This process is considered WLAN or RF planning and Arubas 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:
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 Aruba features, such as ARM, efficient client roaming, and failover.
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.
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. RF Absorbers
Cement/Concrete
Natural Items: Trees/vegetation
Brick RF Reflectors
Metal Objects: Roof-installed air-conditioning equipment, chain link fences (depending on aperture size), other wire fences, or water pipes RF Interference Sources

Military, Commercial Aviation or Weather Radar Systems Line of Sight (Radio Path Planning) AP-85 Series access points are capable of performing as one of the following:
Point-to-point wireless distribution system (WDS) bridge
Point-to-multi-point WDS bridge
Enterprise mesh point (MP)
Enterprise mesh portal (MPP) N O T E To configure the AP-85 as a mesh point or mesh portal, you must install a mesh software license on a Mobility Controller 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 Mobility Controller. 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 Visual Line of Sight Radio 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:
Avoid any partial line of sight between the antennas.
Be cautious of trees or other foliage that may be near the path, or may grow and obstruct the path.
Be sure there is enough clearance from buildings and that no building construction may eventually block the path.
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 Aruba AP-85 Outdoor Access Point Series |
Installation Guide
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).
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). Table 3 Antenna Minimum Height and Clearance Requirements Total Link Distance Max Clearance for 60% of First Fresnel Zone at 5.8 GHz Approximate Clearance for Earth Curvature Total Clearance Required at Mid-point of Link 0.25 mile (0.402 km) 4.6 ft (1.4 m) 0.007 ft (0.002 m) 0.5 mile (0.805 km) 6.2 ft (1.9 m) 0.03 ft (0.010 m) 1 mile (1.6 km) 8.9 ft (2.7 m) 0.13 ft (0.04 m) 2 miles (3.2 km) 12.5 ft (3.8 m) 0.5 ft (0.15 m) 3 miles (4.8 km) 15.4 ft (4.7 m) 4 miles (6.4 km) 17.7 ft (5.4 m) 5 miles (8 km) 20 ft (6.1 m) 7 miles (11.3 km) 23.6 ft (7.2 m) 9 miles (14.5 km) 27 ft (8.2 m) 12 miles (19.3 km) 30.8 ft (9.4 m) 1.0 ft (0.3 m) 2.0 ft (0.6 m) 3.0 ft (0.9 m) 6.2 ft (1.9 m) 10.2 ft (3.1 m) 18.0 ft (5.5 m) 4.6 ft (1.4 m) 6.2 ft (1.9 m) 8.9 ft (2.7 m) 13.1 ft (4.0 m) 16.4 ft (5.0 m) 19.7 ft (6.0 m) 23 ft (7.0 m) 30 ft (9.1 m) 37 ft (11.3 m) 49 ft (14.9 m) 15 miles (24.1 km) 34.4 ft (10.5 m) 28.0 ft (8.5 m) 62.7 ft (19.1 m) N O T E 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. Aruba AP-85 Outdoor Access Point Series |
Installation Guide Outdoor Planning and Deployment Considerations | 17 Figure 9 Antenna Height and Line of Sight Visual Line of Sight Radio Line of Sight 2.4 m A 20 m 3 miles (4.8 km) 5.4 m 17 m B 1.4 m 9 m 12 m
CAUTION N O T E 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. 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. 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:
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.
Place the wireless bridge or mesh link away from power and telephone lines.
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.
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. 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 18 | Outdoor Planning and Deployment Considerations Aruba AP-85 Outdoor Access Point Series |
Installation Guide 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:
Temperature: The wireless bridge or mesh link is tested for normal operation in temperatures from
-30C to 55C. Operating in temperatures outside of this range may cause the unit to fail.
Wind Velocity: The wireless bridge or mesh link can operate in winds up to 90 miles per hour and survive higher wind speeds up to 125 miles per hour. 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.
Lightning: To protect against lightning induced surges, the AP-85 requires lightning protection on the radio interface ports.
CAUTION An Aruba 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 Aruba outdoor AP model and renders the AP susceptible to failure from lightning induced surges.
Rain: The wireless bridge or mesh link is weatherproofed against rain. However, it is 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. For long distance links, plan 0.7 dB of additional margin per km to allow for RF losses that occur during periods of heavy rain or snowfall.
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:
The Ethernet cable length should never be longer than 90 m (295 ft).
Determine a building entry point for the cable (if applicable).
Determine if conduits, bracing, or other structures are required for safety or protection of the cable.
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 AP-85 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.

Installation Guide Appendix A Understanding Antennas Aruba Antennas 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 Aruba 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). Figure 22 Omni-Directional Antenna Figure 23 Directional Antenna Antenna Location Area of Coverage Direction of Coverage Antenna Location Area of Coverage Direction of Coverage Aruba AP-85 Outdoor Access Point Series |
Installation Guide Understanding Antennas | 31 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 Aruba AP-85 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. N O T E 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.

Installation Guide Understanding Antennas | 33 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 Aruba AP-85 Outdoor Access Point Series |

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 Arubas outdoor antenna specifications: http://www.arubanetworks.com/products/access-points/antennas.php. N O T E All figures are shown with a 100 meter (328 feet) mounting height above the ground and for a 18 Mbps coverage area. Detachable Outdoor Antenna Types These are some of the terms used to describe Arubas detachable antenna offerings. Terminology and degree of sector in Arubas 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) omni-
directional 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. Aruba AP-85 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)
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 36 | Understanding Antennas Aruba AP-85 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.

Installation Guide Understanding Antennas | 37 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.
