Aruba AP-85 Outdoor Access Point Series | Installation Guide Outdoor Planning and Deployment Considerations | 15 Chapter 2Outdoor Planning and Deployment ConsiderationsPlanning and Deployment ConsiderationsPrior 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 Aruba’s system engineers can assist in the outdoor planning process. Scale RequirementsThe potentially immense scale of outdoor deployments requires consideration of factors that may not be as important in a typical indoor deployment:zRange (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. zElevation: 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.zNon-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 SourcesIdentifying 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 AbsorberszCement/ConcretezNatural Items: Trees/vegetationzBrick RF ReflectorszMetal Objects: Roof-installed air-conditioning equipment, chain link fences (depending on aperture size), other wire fences, or water pipesRF Interference SourceszOther 802.11a/b/g or broadband access equipment operating nearby

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 SightIf 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:zAvoid any partial line of sight between the antennas.zBe cautious of trees or other foliage that may be near the path, or may grow and obstruct the path.zBe sure there is enough clearance from buildings and that no building construction may eventually block the path.zFor very long distance links, the curvature of the earth (20 cm per km) may need to be considered in the calculation of relative heights. NOTETo 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.Radio Line of SightVisual Line of Sight
Aruba AP-85 Outdoor Access Point Series | Installation Guide Outdoor Planning and Deployment Considerations | 17zCheck 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).zAvoid a path that may incur temporary blockage due to the movement of cars, trains, or aircraft.Antenna HeightA 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 RequirementsTotal Link DistanceMax Clearance for 60% of First Fresnel Zone at 5.8 GHzApproximate Clearance for Earth Curvature Total Clearance Required at Mid-point of Link0.25 mile (0.402 km) 4.6 ft (1.4 m) 0.007 ft (0.002 m) 4.6 ft (1.4 m)0.5 mile (0.805 km) 6.2 ft (1.9 m) 0.03 ft (0.010 m) 6.2 ft (1.9 m)1 mile (1.6 km) 8.9 ft (2.7 m) 0.13 ft (0.04 m) 8.9 ft (2.7 m)2 miles (3.2 km) 12.5 ft (3.8 m) 0.5 ft (0.15 m) 13.1 ft (4.0 m)3 miles (4.8 km) 15.4 ft (4.7 m) 1.0 ft (0.3 m) 16.4 ft (5.0 m)4 miles (6.4 km) 17.7 ft (5.4 m) 2.0 ft (0.6 m) 19.7 ft (6.0 m)5 miles (8 km) 20 ft (6.1 m) 3.0 ft (0.9 m) 23 ft (7.0 m)7 miles (11.3 km) 23.6 ft (7.2 m) 6.2 ft (1.9 m) 30 ft (9.1 m)9 miles (14.5 km) 27 ft (8.2 m) 10.2 ft (3.1 m) 37 ft (11.3 m)12 miles (19.3 km) 30.8 ft (9.4 m) 18.0 ft (5.5 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)NOTETo 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.
18 | Outdoor Planning and Deployment Considerations Aruba AP-85 Outdoor Access Point Series | Installation Guide Figure 9 Antenna Height and Line of SightA 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.Antenna Position and OrientationOnce the required antenna height has been determined, other factors affecting the precise position of the wireless bridge or mesh link must be considered:zBe 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.zPlace the wireless bridge or mesh link away from power and telephone lines.zAvoid 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.zThe 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 InterferenceThe 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 AB3 miles (4.8 km)5.4 m17 m20 m2.4 m12 m9m1.4 mRadio Line of SightVisual Line of Sight!CAUTIONNever construct a radio mast, pole, or tower near overhead power lines.NOTELocal 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.
Aruba AP-85 Outdoor Access Point Series | Installation Guide Outdoor Planning and Deployment Considerations | 19scan 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 ConditionsWhen 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:zTemperature: The wireless bridge or mesh link is tested for normal operation in temperatures from-30°C to 55°C. Operating in temperatures outside of this range may cause the unit to fail.zWind 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.zLightning: To protect against lightning induced surges, the AP-85 requires lightning protection on the radio interface ports.zRain: 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.zSnow 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 CablingWhen 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:zThe Ethernet cable length should never be longer than 90 m (295 ft).zDetermine a building entry point for the cable (if applicable).zDetermine if conduits, bracing, or other structures are required for safety or protection of the cable.zFor lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building.GroundingIt 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.!CAUTIONAn 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.
