Aruba AP-175 Outdoor Access Point | Installation Guide 3AP-175 Hardware OverviewThe following section describes the hardware features of the AP-175.Figure 1 AP-175 Overview (AP-175P shown)Antenna InterfaceThe AP-175 requires the use of detachable outdoor-rated antennas. Select the correct antenna type to support the required frequency band (2.4 or 5 GHz) and the desired coverage pattern. The AP-175 is equipped with four, female N-type antenna interfaces; two on the top of the AP and two on the bottom. The interfaces are grouped into diversity pairs, one pair is marked R0 (Radio 0) and the other pair marked as R1 (Radio 1). R0 supports the 5 GHz frequency band and R1 supports the 2.4 GHz radio band. 1 Antenna Interface (Radio 1) 5 Antenna Interface (Radio 0)2 USB Console Interface 6 Antenna Interface (Radio 1)3 Reserved (AP-175P) or Power Interface (AP-175AC and AP-175DC)7 Ethernet Interface (PoE)4 Antenna Interface (Radio 0) 8 Grounding Point21348765

Use the included USB console cable to connect to the AP. You can download the necessary driver for USB-UART adapter from support.arubanetworks.com under the Tools & Resources tab.Use the following setting to access the terminal:Power InterfaceThe type of power interface on your AP-175 depends on which model you have purchased.AP-175P: This version does not include a power interface since it is only powered by PoE+ (802.3at).AP-175AC: 1x AC power connectorAP-175DC: 1x DC power connector Ethernet InterfaceThe AP-175 is equipped with a 10/100/1000Base-T Gigabit Ethernet port for wired network connectivity. On the AP-175P, this port also supports IEEE 802.3at Power over Ethernet (PoE), accepting 48 VDC as a standards-defined powered device (PD) from a power sourcing equipment (PSE) device, such as a PoE midspan injector. Inversely, the AP-175AC and AP-175DC can act as a PSE device to provide IEEE802.3af PoE power to devices connected to the Ethernet port.Grounding PointAlways remember to protect your AP-175 by installing grounding lines. The ground connection must be complete before connecting power to the AP-175 enclosure. Ensure that the resistance is less than 5 ohm between the ground termination point and the grounding tier. AP-175P LED Status IndicatorsThe AP-175 include visual indicators for power, link, and radio status. Additionally, each radio has a four-LED array that indicates received signal strength (RSSI).

Aruba AP-175 Outdoor Access Point | Installation Guide 7Outdoor Planning 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: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.R0 Radio 0 Status Off Radio 0 disabledOn (Amber) Radio 0 enabled in WLAN modeBlinking Air Monitor (AM) modeR1 Radio 1 Status Off Radio 1disabledOn (Blue) Radio 1 enabled in WLAN modeBlinking Air Monitor (AM) modeRSSI (Radio 0) RSSI Level for Radio 0 Off RSSI disabled/no signal4 Step Progressive Bars (Red)25/50/75/100% Each bar represents a progressive increase in signal strength, with 4 bars representing maximum signal strength (100%).Minimum data rate: One lit LEDsMaximum data rate: Four lit LEDsRSSI (Radio 1) RSSI Level for Radio 1 Off RSSI disabled/no signal4 Step Progressive Bars (Blue)25/50/75/100% Each bar represents a progressive increase in signal strength, with 4 bars representing maximum signal strength (100%).Minimum data rate: One lit LEDsMaximum data rate: Four lit LEDsTable 3 AP-175AC/DC LED Status Indicators (Continued)LED Function Indicator Status
8Aruba AP-175 Outdoor Access Point | Installation GuideIdentifying 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 AbsorbersCement/ConcreteNatural Items: Trees/vegetationBrickRF ReflectorsMetal Objects: Roof-installed air-conditioning equipment, chain link fences (depending on aperture size), other wire fences, or water pipesRF Interference SourcesOther 802.11a/b/g/n or broadband access equipment operating nearbyIndustrial RF welding equipment or other Industrial, Scientific and Medical (ISM) equipment that utilizes RF to heat or alter the physical properties of materialsMilitary, Commercial Aviation or Weather Radar SystemsLine of Sight (Radio Path Planning)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 4 illustrates the concept of a good radio line of sight.Figure 4 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: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.Radio Line of SightVisual Line of Sight
Aruba AP-175 Outdoor Access Point | Installation Guide 9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.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 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 4 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)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 Figure 5.
10 Aruba AP-175 Outdoor Access Point | Installation GuideFigure 5 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 4.7 m (15.4 ft). The tree tops on the hill are at an elevation of 17.7 m (58.1 ft), so the antennas at each end of the link need to be at least 22.4 m (73.5 ft) high. Building A is six stories high, or 20 m (66 ft), so a 2.4 m (7.9 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 1.4 m (4.6 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: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 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 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.AB3 miles (4.8 km)4.7 m17.7 m20 m2.4 m12 m9m1.4mRadio Line of SightVisual Line of Sight!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.
Aruba AP-175 Outdoor Access Point | Installation Guide 11If 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:Temperature: The wireless bridge or mesh link is tested for normal operation in temperatures from -30ºC to 55ºC. 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 165 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-175 requires lightning protection on the radio interface ports.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.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 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: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 buildingGroundingIt is important that the wireless bridge or mesh link, cables, and any supporting structures are properly grounded. Each AP-175 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. Ground the access point first using the external ground stud on the unit before making any other connection.!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
12 Aruba AP-175 Outdoor Access Point | Installation GuideInstalling Antennas1. Before connecting the antennas, identify which of your antennas are 2.4 GHz and which are 5 GHz. On the AP-175, the 2.4 GHz antennas must be installed the R1 radio interfaces and the 5.0 GHz must be installed on the R0 radio interfaces. 2. After identifying which antennas will go where, install them by placing the antenna connector over the corresponding connector and the AP and turning the connector clockwise until hand tight. Repeat this process for each antenna.3. Place the included metal weatherproof caps over any unused antenna interfaces by turning them clockwise until hand tight.Weatherproofing ConnectionsWeatherproofing your antenna and/or cable connections on your outdoor AP is essential to reliability and longevity of your product. This process prevents water from entering the AP or antennas through the connectors. A good weatherproofing job consists of three wrappings: 1. electrical tape 2. butyl rubber3. electrical tapeThe first wrapping of tape should be at least two layers, followed by a single wrap of butyl rubber, and four-layer wrap of electrical tape. This provides good protection from water, heat, and other potential hazards that could damage your AP or antennas. Additionally, wrap your connections such that water is always directed down and away from connections. Required Items and Tools3/4” (19 mm) Vinyl Electrical Tape Butyl Rubber TapeKnife or Box CutterTypes of ConnectionsThe following sections provide guidance on weatherproofing directly connected antennas (Figure 6) and cable connections (Figure 7). The same materials are needed for weatherproofing both types of connections but the procedure is slightly different. For weatherproofing directly connected antennas, see "Weatherproofing Directly Connected Antennas" on page14. For weatherproofing cable connections, see "Weatherproofing Cable Connections" on page17.

14 Aruba AP-175 Outdoor Access Point | Installation GuideImportant Points to RememberDo not cover the weep holes on the antennas. Doing so can restrict the release of condensation from the antennas.Proper weatherproofing is not a fast process. Set aside ample time to complete the steps outlined below.When wrapping, make the each layer of tape as flat as possible. Wrinkles and folds in the tape create places for water and moisture to gather. Weatherproofing Directly Connected AntennasFirst Wrapping of Tape1. Before wrapping the antennas, locate the weep holes (Figure 6). Weep holes allow condensation that has built up inside the antenna to escape.2. Prepare the antenna connector by cleaning and drying it.3. Cut a 4” (100 mm) strip of electrical tape from the roll. Pre-cutting the tape into strips makes in easier to maneuver the tape around the antennas and other components of the AP’s case.4. Beginning just below the weep holes, tightly wrap the connection with a layer of the 3/4” (19mm) electrical tape. Overlap the tape to a half-width. 5. Repeat steps 3 and 4 until the wrapping extends all the way to the AP’s case.Figure 8 First Wrapping of Tape Wrap tape fromjust above knurledsection to base ofantenna mountPieces of tape as neededLeaveweep holesuncoveredAP175_12

16 Aruba AP-175 Outdoor Access Point | Installation GuideSecond Wrapping of Tape1. Cut a 4” (100 mm) strip of electrical tape from the roll.2. Where you begin wrapping depends on the orientation of the antenna. Water should flow in the opposite direction of the wrapping to prevent water from entering the connector between the layers of tape.Therefore, if the antenna is facing up, you should begin wrapping at the AP end of the connector. This will ensure that your fourth and final layer will be layered correctly. Conversely, if your antenna is facing down, you should begin wrapping on the antenna end of the connector. 3. After completing the fourth layer of tape, check your work to ensure there are no places where water can collect. If there are, you must smooth out those areas with additional layers of tape or remove the weatherproofing and begin again. Figure 11 Completed Wrapping (Antenna on Top of AP)4.

Repeat this process for all connectors.Installing the AP-175The AP-175 can be installed on a wall or attached to a pole. The following section describes how to attach the necessary hardware to the AP and how to mount the AP in the selected location.Selecting the Installation SiteThe site should be located within at least a 60% range of the 1st fresnel zone without obstacles to provide line of sight (LOS) transmission, increase coverage capacity, and minimize the number of necessary sites.If no LOS is secured, areas in non-line-of-sight (NLOS) areas could be covered as well, but the distance of coverage and area of coverage are decreased; more sites are needed to provide coverage for same area than in the LOS scenario.Interference must be considered in site selection. The new site should avoid known interference, unless the interference is controllable.Keep the AP-175 away from places that are susceptible to high temperature, dust, harmful gas, inflammable, explosive, electromagnetic interference (high power radar, radio station and transformer), unstable voltage, heavy vibration, or loud noise.
