Site Prerequisites ! DANGER: The WaveACCESS Office Router outdoor antennas are intended for mounting on a roof, or the side of a building. Installation shall not be attempted by someone who is not trained or experienced in this type of work. The antenna has to be installed by a suitably trained professional installation technician or a qualified antenna installation service.
Overview of the Indoor Installation Overview of the Indoor Installation 2 To setup a point-to-point wireless connection, you will need: ■ Two WaveACCESS Office Router Kits, and ■ Two Low-loss antenna cables. Figure 2-1 shows an overview of the hardware setup for the indoor installation. Figure 2-1 Overview Indoor Installation On each end of the wireless link you will need: A. A WaveACCESS IEEE adapter card (see “Selecting the Right WaveACCESS Card” on page 2-4). B.
Overview of the Indoor Installation ! WARNING: The WaveACCESS Office Router, the WaveACCESS Surge Arrester and the antenna mast must be connected to the same grounding system as described in “Grounding System” on page 2-15. Selecting the Right WaveACCESS Card 2 Wireless communications are usually subject to local radio regulations, where additional regulations may apply to outdoor antenna communications.
Overview of the Indoor Installation the correct card type that complies with the regulations that apply in your country. When you order the WaveACCESS outdoor antenna equipment as separate components, make sure that you order the correct product items. In case you are not certain about the regulations that apply in your country, consult your local Lucent Technologies Sales Office.
Overview of the Indoor Installation Placement of the WavePOINT-II Hardware 2 The WavePOINT-II hardware of your WaveACCESS Office Router device is designed for indoor mounting and operation. The ideal location to install your WavePOINT-II unit must satisfy the following requirements: The location provides a connection to a grounding type AC wall outlet (100-240 VAC), using the standard power cord as supplied with the unit.
Overview of the Indoor Installation Prior to mounting the WavePOINT-II unit you are advised to, carefully calculate: ■ The distance between the intended location of your WavePOINT-II unit and the location of the antenna mast, and ■ The height of the antenna on the mast.
Overview of the Indoor Installation Placement of the Surge Arrester 2 The WaveACCESS Surge Arrester is an indispensable part of your outdoor antenna installation, to protect your sensitive electronic equipment from transients or electro-static discharges at the antenna.
Overview of the Indoor Installation The cable should not be installed into “tight” positions, as bending or applying excessive force to the connectors may damage the antenna cable. Always allow the cable to bend naturally around corners. The recommended bend radius is 25 mm (1 in.). The antenna cable must be secured along its complete length. No part of the antenna cable should be allowed to hang free. This is particularly important for cable parts that are installed outdoors.
Overview of the Outdoor Installation Overview of the Outdoor Installation 2 The outdoor installation of the link (point-to-point or point-tomultipoint) will consist of the following components: ■ The Lucent Technologies Antenna ■ The Lucent Technologies proprietary low-loss antenna cable (available in different cable lengths). ■ Antenna Mast/Wall Bracket for the antenna (not included with kit). ■ An adequate Grounding System that meets the requirements described on page 2-15.
Overview of the Outdoor Installation Antenna Placement 2 To achieve maximum performance for your wireless outdoor connection, the WaveACCESS Outdoor Antennas must have clear line-of-sight. Line-of-sight can be defined as: ■ No obstacles in the direct path between the two antennas. ■ No obstacles within a defined zone around the antenna beam. You need to be aware that the shape of a radio beam is not straight and narrow like a laser beam.
Overview of the Outdoor Installation Figure 2-2 Potential Obstacles for a Directional Antenna To minimize the influence of obstacles, signal interference or reflections please note the following guidelines: ■ Mount the antenna as high as possible above the “ground” to allow maximum clearance: ■ In open areas “ground” is the actual surface of the earth ■ In dense urban areas “ground” is to be interpreted as the height of the highest obstacle in the signal path between the two antenna sites.
Overview of the Outdoor Installation Environments with large reflective surfaces include: ■ Mirrored-glass buildings ■ Crowded parking lots ■ Water or moist earth and moist vegetation ■ Above ground power/telephone lines Weather conditions such as rain or snow usually will not have much impact on the performance of your WaveACCESS Outdoor System, provided that you sealed all cable connectors using the weather-proofing tape.
Overview of the Outdoor Installation Antenna Mast/Wall Bracket 2 Basically there are two ways to erect an antenna mast: ■ Tripod Mount ■ Wall (Side) Mount Tripod Mount 2 The tripod mount is used primarily on peaked and flat roofs. The antenna mast must be secured to the roof using 3 or 4 guy wires that are equally spaced around the mast. When the height of the antenna mast is more than 3 meters (10 ft), you are advised to use at least three guy wires for each 3 meter (10 ft) section of the mast.
Overview of the Outdoor Installation Antenna Mast Requirements 2 To accommodate the WaveACCESS antennas, the antenna mast must satisfy the following requirements: a. The construction of the mast must be of a sturdy, weatherproof and non-corrosive material like for example galvanized or stainless steel construction pipe. b. Diameter of the mast should be between 29 mm (1.125 in.) and 41 mm (1.625 in.). c. The height of the antenna mast must be sufficient to allow the antenna to be installed at least 1.
Overview of the Outdoor Installation comply with the National Electrical Code and safety standards that apply in your country. Always check with a qualified electrician if you are in doubt as to whether your WaveACCESS Outdoor installation is properly grounded. Lucent Technologies Antenna 2 The Spread Spectrum Technology of the WaveACCESS radio requires high gain antennas.
Overview of the Outdoor Installation It will be the responsibility of the end-user to ensure that an outdoor antenna installation complies with local radio regulations. Lucent Technologies is not liable for any damage or violation of government regulations that may arise from failing to comply with these guidelines. Antenna Alignment 2 For optimal performance of your wireless link, make sure that the antennas are properly aligned (facing one another “eye-to-eye”).
Overview of the Outdoor Installation Figure 2-3 WaveMANAGER/OR Wireless Link Test Antenna Polarization 2 The standard mounting method for Lucent outdoor antennas is designed for vertical polarization. In some cases you might consider mounting the antenna for horizontal polarization. For example to minimize the influence of cross-talk between antennas when: ■ You plan to mount multiple directional antennas to the same mast.
Overview of the Outdoor Installation ■ For horizontal polarization, the arrow on the protective casing of the 14 dBi Directional Antenna must be pointing left or right. It does not matter what type of polarization you choose, as long as the antennas at both ends of the communications link have been mounted in the same polarity. NOTE: When mounting antennas using different polarization options, always verify that the polarization on both ends of the dedicated links are the same.
Before Climbing the Roof... Before Climbing the Roof... 2 Please consult Chapter 3 ”Determine Range & Clearance” to verify whether you have the correct type of antennas and sufficient clearance in the signal path to cover the distance between the two sites that you wish to connect via the wireless link. Before you start installation, also check the contents of your outdoor kit. If there are signs of shipment damage, or if any of the items are missing, please inform your supplier.
Determine Range & Clearance 3 Contents Introduction 3-1 Determine the Outdoor Range 3-2 Determine the Maximum Range ■ Type of Outdoor Antenna Equipment ■ Data Speed of the Wireless Link Determine the Cable Factor Determine the Clearance Factor Examples Point-to-Point Links ■ Calculate the Clearance effect on Range ■ Calculate the Cable effect on Range Point-to-MultiPoint Links 3-3 3-4 3-7 3-8 3-9 3-13 3-13 3-14 3-15 3-16
Determine Range & Clearance 3 Introduction 3 When you read about wireless outdoor products, you will often encounter the terms “output power” of the radio and “gain” of the antenna equipment as measures for the “strength” of the transmitted signal. ■ Output Power of radio equipment is often subject to maximum limits as defined by local radio regulations. Consequently Output Power is not by definition the way to enhance wireless performance.
Determine the Outdoor Range Determine the Outdoor Range 3 The range of your outdoor antenna installation is closely related to a number of different factors.
Determine the Outdoor Range Determine the Maximum Range 3 The maximum range of your WaveACCESS Office Router antenna system is based on the: ■ ■ ■ Type of Outdoor Antenna Equipment Data Speed of the Wireless Link (see page 3-7). Clearance of the Signal Path (see page 3-9). NOTE: The values listed in this section are based upon calculations that assume “optimal radio conditions”. They do not represent a guarantee that the same maximum distance can be achieved at your location.
Determine the Outdoor Range Type of Outdoor Antenna Equipment 3 As described in the previous chapters, Lucent Technologies offers different types of outdoor antennas, and cable lengths to design your WaveACCESS Office Router outdoor antenna installation. ■ The 14 dBi Directional Antenna provides maximum range, but due to its narrow signal beam, requires precise antenna alignment to achieve optimal performance.
Determine the Outdoor Range Table 3-1 Outdoor Range for FCC Products Antenna Type Transmit Rate 14 dBi Yagi Low Speed 14 dBi Yagi 7 dBi Omni Range Clearance Range Clearance 15.8 km. 20.3 m. 7.1 km. 11.3 m. 66.8 ft. 4.3 mi. 37.2 ft. 9.7 mi. Standard Speed 11.2 km. 15.4 m. 5.0 km. 9.1 m. 6.9 mi. 50.7 ft. 3.1 mi. 29.9 ft. 12.1 m. 3.5 km. 7.5 m. Medium Speed 7.9 km. 4.8 mi. 39.8 ft. 2.1 mi. 24.7 ft. High Speed 5.6 km. 9.8 m. 2.5 km. 6.3 m. 3.4 mi. 32.2 ft. 1.5 mi. 20.7 ft.
Determine the Outdoor Range All values listed in Table 3-1 and Table 3-2 apply to antenna installations where: ■ Antennas have been mounted for vertical polarization (being the default mounting method). ■ On both ends of the wireless link the maximum length of the antenna cable is 6 m./15ft., and ■ The clearance of the signal path (both horizontally and vertically) is equal or better than the listed value in the greyshaded column.
Determine the Outdoor Range Data Speed of the Wireless Link 3 By default, the radio of WaveACCESS Office Router products will always try to transmit at the highest available transmit rate. As data transmissions at lower speeds can travel larger distances than transmissions at the highest transmit rates, the WaveACCESS Office Routers have been designed to apply an “Automatic Transmit Select” mechanism.
Determine the Outdoor Range Determine the Cable Factor 3 The range value calculations listed in Table 3-1 and Table 3-2 were based on antenna installations where both antennas were connected to a 6m/15 ft. cable. ■ If this is the case in your situation, the Cable Factor for your installation is 100%. ■ If you are using different cables, you will need to determine the Cable Factor as described below, to calculate the probable range for your WaveACCESS Office Router installation.
Determine the Outdoor Range Figure 3-1 Cable Factor Diagram Determine the Clearance Factor 3 For optimal performance of your outdoor antenna link, it is important that the signal path between the two WaveACCESS Office Routers provides sufficient clearance. NOTE: A wireless outdoor antenna link that lacks sufficient clearance will suffer from poor performance, which is typically perceived as slow network response times.
Determine the Outdoor Range Figure 3-2 Fresnel Zone If any significant part of this bulged zone is obstructed, a portion of the radio energy will be lost, which may affect the performance of your wireless link in terms of maximum range and/or transmit rate. Looking at Figure 3-2 you will see two variables that determine the shape of the radio beam, also referred to as Fresnel Zone: a. The distance between the antennas b.
Determine the Outdoor Range The minimum clearance for the various antenna combinations and distances is listed in the grey-shaded columns of Table 3-1 and Table 3-2, where clearance should be interpreted as follows: ■ In open areas without obstacles in the signal path, clearance is measured as height above the surface of the earth. For example, if the antenna is mounted on the roof, this height includes the height of the building plus the height of the mast above the rooftop.
Determine the Outdoor Range To determine the effect of insufficient signal path clearance, you will need to determine the Clearance Factor as described below, and calculate its effect on the range for your antenna installation using the formula described on page 3-2. ■ If the clearance for your antenna installation is equal to, or better than the minimum clearance requirement identified in Table 3-1 and Table 3-2, the Clearance Factor for your installation is 100%.
Examples Examples 3 Point-to-Point Links 3 Suppose you are installing a wireless point-to-point link between two Remote Office Routers as pictured in Figure 3-4 below, where: ■ Both sites have been equipped with a 14 dBi Directional Antenna, connected via 6m.(15ft.) antenna cables. ■ The distance between site a and b is 4 km. (2.5 mi.). ■ The site is located in the US, which allows the use of FCC approved equipment.
Examples Calculate the Clearance effect on Range 3 In the example pictured in Figure 3-4 on page 3-13, we see a set of trees in the signal path. Let’s suppose the clearance (c) between these trees and the signal path is only be 7.5 m (24.5 ft.). 1. Using a calculator we can easily determine that this 7.5 m (24.5 ft.) is about 75% of the required 9.8 m. (32.2 ft.) clearance for maximum range. 2.
Examples Calculate the Cable effect on Range 3 On page page 3-13 we presumed that at both sites the antenna were connected via 6m.(15 ft.) cables. If we would replace the 6m.(15 ft.) cable at building b, with a longer 22 m. (75 ft.) cable, we would need to look at the Cable Factor effect of this longer cable. 1. Table 3-3 on page 3-8 tells us that this new cabling combination is marked as cable combination B. 2.
Examples Point-to-MultiPoint Links 3 Suppose you are installing a wireless Point-to-Multipoint link between a WaveCAMPUS Central Office Router and two Remote Office Routers as pictured in Figure 3-5 below, where: ■ The Central Office Router in building c is connected to a 7 dBi Omni-Directional Antenna, and ■ The two remote sites a and b have been equipped with a 14 dBi Directional Antenna. ■ All sites have been connected via 22m.(75ft.) antenna cables.
Examples NOTE: In this example we will only demonstrate the calculation for the link between building a and c. However as different clearance factors may apply for each of these links, you are advised to calculate the actual range for each link individually when designing a “real” outdoor antenna link. For the purpose of this example we presume that: ■ The antenna installation will be installed in a dense urban area, where the distance between building a and building c is 1.6 Km.(1.0 mi.).
Examples 4. If we import all this information into the range calculation formula, your probable range for High Speed transmissions would become: Range= 1.8 Km. (3.4 mi.) x 75% x 65% = 0.8 Km (0.5 mi.) For campus type environments, this range will probably be sufficient to connect multiple buildings. However if you would need to cover a larger distance, you can either: ■ Relocate the WavePOINT-II hardware to a location that allows you to use a shorter cable length.

Installing the Antenna Planning Antenna Installation 4 4 Carefully plan the day for your outdoor antenna installation. Do not install the antenna in wet or windy conditions, during a thunderstorm or when the area where the equipment will be installed is covered with ice or snow. The grounding system for the antenna mast, WavePOINT-II hardware and WaveACCESS Surge Arrester should be installed before the cable from the antenna is connected to the lightning arrestor.
Planning Antenna Installation Safety Precautions 4 Please read this section carefully before beginning the installation. All requirements listed below should be satisfied prior to starting installation of your WaveACCESS outdoor antennas. ! DANGER: The WaveACCESS Office Router outdoor antennas are intended for mounting on a roof, or the side of a building. Installation shall not be attempted by someone who is not trained or experienced in this type of work.
Planning Antenna Installation ! DANGER: Outdoor antennas and antenna cables are electrical conductors. Transients or electrostatic discharges that may occur at the antenna (for example a lightning strike during thunderstorms) may damage your electronic equipment and cause personal injury or death to persons touching the exposed metal connectors of the antenna cable. To avoid damage and personal injury, the entire antenna cabling system must be grounded at all times.
Planning Antenna Installation 4. Antennas shall be mounted in such a manner to minimize the potential for human contact during normal operation. In order to avoid the possibillity of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20cm (8 inches) during normal operation. 5. The low-loss antenna cable that will connect the antenna with the lightning arrestor must be at least 1m (3 ft.) away from any high voltage or high current cable. 6.
Planning Antenna Installation Installation Overview 4 The installation process can be summarized in the following seven steps. 1. Verify that the support structure for the antenna has been connected to the grounding system. If this is not the case you should do so now. 2. Connect the exposed metal connectors of the low-loss antenna cable to the grounding system. 3.
Mounting the Antenna Mounting the Antenna 4 The WaveACCESS Office Router kit is available as a 2.4 GHz Kit with either a 14 dBi directional or a 7 dBi omni-directional antenna. This section includes mounting instructions for each of these antenna types. When mounting multiple antennas on a single mast, use the following methods to minimize the influence of cross-talk interference between the antennas: ■ Place your antennas as far apart as you can.
Mounting the Antenna 2. Note the arrows on the mounting plate. 3. Mount the antenna with the arrows pointing up. 4. Attach the antenna to the mast as pictured in Figure 4-1 on page 4-7, using the U-bolts and bolt heads, the Metal Backing Plate and nuts. 5. Proceed with “Connecting the Antenna Cable” on page 4-11. ! CAUTION: Always place flatwashers between heads (or nuts) and the plastic mounting plate. Avoid overtightening the nuts and screws to prevent damage to the mounting plate.
Mounting the Antenna Mounting on a Flat Surface 4 For mounting the antenna to a flat vertical surface, you must provide a smooth surface for the antenna mount. On wall surfaces such as brick, block or stucco, use an intermediate surface such as a plywood board or metal plate between the wall and antenna. The intermediate surface will need to be of sufficient strength to prevent distortion of the antenna base when the mounting hardware is tightened. To mount the antenna proceed as follows: 1.
Mounting the Antenna 2. Note the arrows on the mounting plate. 3. Mount the antenna with the arrows pointing up. 4. Attach the antenna using the intermediate plate, Metal Backing Plate and flatwashers as shown in Figure 4-2. 5. Proceed with “Connecting the Antenna Cable” on page 4-11. ! CAUTION: Always use flatwashers between the screws and the plastic mounting plate. Avoid overtightening nuts and screws to prevent damage to the mounting plate.
Mounting the Antenna Use a wrench to tighten the nuts and ensure the bracket will be fixed to the top of the mast. 5. Next feed the antenna cable of the 7 dBi omni-directional antenna (item A) through the hole of the mounting bracket. 6. Slide the antenna down, until its metal base is enclosed by the mounting bracket as pictured in Figure 4-3. Figure 4-3 Mounting the 7 dBi Antenna to a Mast 7. Use a wrench to tighten the bracket bolt (item G) to fix the antenna into its position.
Connecting the Antenna Cable Connecting the Antenna Cable 4 Once the antenna is properly installed, you can connect the antenna to the WaveACCESS Wireless System via the WaveACCESS Surge Arrester. 1. First connect the antenna cable to the antenna 2. Secure the antenna cable to the mast such that the cable connectors do not support the full weight of the cable. 3. Connect the opposite end of the antenna cable to the WaveACCESS Surge Arrester.
Connecting the Antenna Cable 7. Secure the cable along its complete length. No part of the cable should be allowed to hang free. This is especially important for those parts that are routed outside the building. 8. Use the stretch tape provided to seal all outdoor connectors. Sealing the Cable Connectors 4 Most problems associated with wireless outdoor installations are related to degrading performance due to the effects of corrosion of the antenna cable and cable connectors.
