Tsunami® MultiPoint 10200 Series - Antenna Installation Guide 61Antenna Installation1.1 Safety PrecautionsListed below are the safety precautions to be satisfied, prior to the outdoor antennas installation:•Outdoor antennas and antenna cables (good conductors of electricity) should be installed properly to avoid the transients or electrostatic discharges (that occur due to lightning during thunderstorm) from damaging your equipment and causing personal injury or death to the persons touching the exposed metal connectors of the equipment.•When installing, disconnecting, or replacing one of the cable components, ensure that each of the exposed metal connectors of the antenna cabling system are grounded locally.•Do not install the antenna, where there is a possibility of contact with the high-voltage arc-over from the power cables or service drops to the buildings. Ensure that the antenna-mast or antenna-tower are not close by any power line, during the installation or removal of antennas. •Apply a Danger label on a plainly visible area of the antenna support structure.•Do not climb the rooftops during a thunderstorm, in wet or windy conditions, or on the equipment installation area which is covered with ice or snow. •Do not touch the antennas, surge arrestors, or antenna cables during a thunderstorm.•Install the antennas at a safe distance (at least twice the height of the antenna-mast plus the antenna) from power lines or telephone lines. •Mount the antennas at a safe distance, avoiding any human contact during the normal equipment operation. •Humans should ensure 50 cm separation from the antenna (8 inches), avoid the possibility of exceeding the FCC radio frequency exposure limits, during the normal operation of the equipment.•Verify that the low-loss antenna cable used to connect the antenna with the surge arrestor, or the ethernet cable used to connect the surge arrestor, are at least 1 m (3 ft.) away from any high voltage current cable.•Check whether the antenna mast and its guy wires or wall bracket are positioned correctly and secured properly to the roof or walls. Also, ensure that the base area, where the antenna-mast is mounted is weatherproofed.•Ensure, that the grounding system for the antenna mast and the surge arrestor have been installed. The grounding system must comply with the local electrical code and other requirements. See Grounding the Antennas.•Always consult an experienced electrician to assure that the antenna mast, surge arrestor, and the equipment hardware are grounded properly.•The antenna cable between the antenna and the surge arrestor should be grounded. Ensure that the exposed metal connector of the cable is grounded locally, if the cable is disconnected at one end (disconnected to replace the surge arrestor).1.2 Installation ProcessFollow the following step-by-step procedure to install outdoor antennas:1. Ensure that all the materials, essential to install the outdoor antennas are acquired. See Required Materials.2. Once you have acquired all the required materials, refer Quick Installation Guide (that comes along with your product) to mount the outdoor equipment and begin the outdoor antenna installation.3. Verify the optimal antenna placement, maintaining a clear line-of-sight. See Determining the Optimal Antenna Placement.4. Mount the antenna to the support structure, following the guidelines as described in Mounting the Antenna.5. Verify that the device, support structure for antenna (antenna-mast) and entire cable set-up for the antenna are connected properly. See Connecting the Cables.6. Connect the antenna cable to the antenna. See Connecting the Antenna Cable.
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 77. Ensure that the cabling of ethernet / power cables and the surge arrestor is proper. See Connecting the Surge Arrestor and Ethernet / Power cables.8. Ensure that the antennas are grounded properly to the grounding system, satisfying the local electrical code requirements. See Grounding the Antennas.9. Once the antenna is properly positioned, grounded and the outdoor cable setup is verified, secure all the cables and use weatherproofing tape to seal all the outdoor connectors. See Sealing the Cable Connectors.10. Make sure that the outdoor antennas at both the ends maintain the same antenna polarizations. : For easy outdoor antenna installation, note the following: •Go through the Safety Precautions.•Read all the requirements outlined in this chapter. See Required Materials.•Familiarize yourself with the antenna and the radio-specific mounting instructions, prior to climbing any roof or ladder.•Verify that you have arranged all safety measures for outdoor installation or rooftop installation. See Safety Precautions.•Test all the equipment before beginning the actual rooftop installation, to determine if all the required equipment is functioning properly. • Install the grounding system for the antenna mast, device, and surge arrestor before connecting the cables. This protects your system against lightning strikes during installation.•When you remove or relocate the antenna, verify the Required Materials and Safety Precautions, before you restart the installation process, and follow the above steps in exactly the reverse order.1.2.1 Required MaterialsThe outdoor installation of the equipment and the antennas, require the following:•An outdoor radio unit.•An outdoor antenna, supporting the local electrical code.•A low-loss antenna cable. : We recommend you to use a coaxial antenna cable (P/N CBL-5054-600-6), that is available with your distributor.•Antenna mast or wall bracket for the antenna/device.•A grounding system that meets the local electrical code. See Grounding the System.•Weatherproofing kit for sealing all the cable connections. See Sealing the Cable Connectors.•Tools and material to mount the antenna. See Mounting the Antenna.•Tape or wraps to attach the antenna cable to the mast.•Ethernet cable (RJ 45 cable / Cat5e ethernet cable) with waterproof cap.•Proper tools for system installation.•Ethernet Surge Arrestor and Surge Protector (RF-cable). See Connecting the Surge Arrestor and Ethernet / Power cables.Ensure that you have acquired all the materials listed above, to begin with the outdoor antenna installation. Refer to the Quick Installation Guide, that comes along with your product, for details on mounting the outdoor equipment.
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 81.2.2 Determining the Optimal Antenna PlacementTo achieve the maximum throughput, the outdoor antenna must have clear line-of-sight with the antenna at the other end. The outdoor antennas are said to have a clear line-of-sight, when there are:•No obstacles in the direct path between the antennas (antenna beam)•No obstacles within a defined zone around the antenna beamAlthough, the radio signal can work well without the clear line-of-sight in urban environments, where the signal is transported by reflection rather than transporting it directly along the obstacles. The following figure shows some typical examples of obstacles you must avoid in urban environments, for the directional antenna to operate effectively.Figure 1-1 Obstacles to be avoided: (a) Neighbouring Buildings (b) Tall Trees (c) Power LinesTo minimize the signal interference or reflections due to obstacles, 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.•Avoid trees in the signal path to avoid signal absorption due to seasonal changes (leaves or ice).•Install the antenna at least 2 m (6 ft.) away from all other antennas.Other situations in which reflections of the radio signal may cause interference are environments with large reflecting surfaces, parallel or partly perpendicular to the antenna beam, such as:•Mirror-glass buildings.•Crowded parking lots.•Water surface, moist earth and moist vegetation.•Electric power lines and telephone lines above the ground level. : Reflective surfaces can be used to improve the performance of a link, if the direct line-of-sight is impaired or absent.In the absence of a direct path or clear line-of-sight, transporting a signal through reflection depends on two factors:•Fresnel Zone: It is required to calculate the distance of the obstacle from the antenna. See Fresnel Zone.•Clearance Factor: It is required for optimal performance (See Clearance Factor). Ensure that the type and placement of the antennas leave sufficient clearance of the Fresnel Zone at the maximum width of the bulge, which is typically at the mid-point between the antennas.
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 91.2.3 Mounting the AntennaMounting an antenna directly to the wall does not let you align the antenna properly with the corresponding antenna at the opposite end of your wireless link. Poor antenna alignment typically results in poor performance and therefore, we recommend mounting the antennas to a mast. The two methods followed frequently to erect an antenna mast are: •Tripod Mount: The tripod mount is used primarily on peak and flat roofs. The antenna mast must be secured to the roof using three or four guy wires equally spaced around the mast. When the height of the antenna mast is more than 3 meters (10 ft.), you should use at least three guy wires for every 3-meter (10-foot) section of the mast.•Wall (Side) Mount: A wall (side) mount allows you to mount the antenna (mast) on the side of a building or on the side of an elevator penthouse. This provides you with a convenient mounting location, when the roof overhang is not excessive or when the location is high enough to provide a clear line-of-sight. 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 as possible.– Mount the directional antennas, such that the identical side of both the antennas face the same direction. : As the mounting procedures for the various antennas differ from one another, refer to the guide that comes along with the antenna.1.2.3.1 Antenna Mast RequirementsTo accommodate the antennas, the antenna mast must satisfy the following requirements:•The construction of the antenna mast must contain sturdy, weatherproof, and non-corrosive material (for example, galvanized or stainless steel construction pipe).•Diameter of the mast should be between 35 mm (1.4 inches) and 41 mm (1.6 inches). The diameter of the antenna mast vary depending on the type of antenna you intend to install.•The height of the antenna mast must be high enough to allow the antenna to be installed at least 1.5 m (5 ft.) above the roof. The height of the antenna should be at least 3 m (10 ft.) above, if it is a metal roof.•The antenna mast or wall bracket must be free from any material (like paint) that prevents a good electrical conduction with the antenna.1.2.3.2 Antenna Tilt Angles and corresponding EIRP values : The below mentioned particulars are applicable only to the devices operating in U-NII-1US frequency band 5.15 GHz - 5.25 GHz.The Federal Communications Commission (FCC) established new rules for the 5.15 GHz - 5.25 GHz U-NII-1 band in the Report and Order FCC-14-30A1 are effective from June 2nd, 2014. With the help of professional installation, all the Proxim devices can be configured to comply with the power requirements set in the rules. For an angle of elevation which is above 30 degrees, the maximum EIRP limit should be set to 125 mW (21 dBm). The compliance can be achieved through proper selection of antenna, angle of elevation, and Tx power control to provide reasonable protection from harmful interference to users, authorized devices, and co-channel NGSO/MSS operations.: The antennas installed at both the ends of a wireless link should maintain same antenna polarizations.
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 10The antenna/devices located at different altitudes should be tilted at the correct angle to efficiently transmit/receive the signals between the devices in the wireless network. The following figure shows the antenna tilt and its importance when the successive devices are located at different elevations above the ground.Figure 1-2 Typical installation showing device/antenna tilt angleThe radiation patterns for a device with Horizontal polarized antenna in Azimuthal and Elevation planes are shown below in Figure 1-3. As per the regulatory domain, there are no limitations to the Azimuthal plane with respect to EIRP, but the Elevation plane has a limit specific to EIRP above 30 degrees as 21 dBm. To comply with this specification, Proxim products have an option to control the transmit power based on the installation tilt angle and the radiation pattern of the antenna. Figure 1-3 Antenna radiation patterns for Azimuthal and Horizontal PlanesThe formula used for the calculation of Transmit Power is given below: Transmit Power = EIRP - G (30- 0) - MIMO Gain Where, EIRP - Equivalent Isotropically Radiated Power G (30- 0) - Antenna gain at (30- 0) in the elevation plane MIMO Gain - Gain for Multi Input Multiple Output products (2x2 MIMO Gain is 3 dB and 3X3 MIMO Gain is 4.8 dB)•The calculation of Transmit Power to comply with the EIRP limits for an antenna with a gain of 22 dB is explained below for three different tilt angles:•Case 1: 0 = 00 (No antenna tilt)
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 11– The antenna gain for 0 = 00 is shown in the following figure:Figure 1-4 Antenna gain at (30- 0) = 300– Transmit Power = EIRP - G (30- 0) - MIMO Gain = 21 - 5 = 16 dBm•Case 2: 0 = 150 (antenna tilted upward)– The antenna gain for 0 = 150 is shown in the following figure:Figure 1-5 Antenna gain at (30- 0) = 150

Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 131.2.4 Connecting the CablesOnce the outdoor antennas are properly mounted, the cable setup essential to complete the outdoor antenna installation is depicted in the following figure: Figure 1-7 Cable SetupThe entire outdoor cabling setup requires the following cabling to be done:1. Connecting the Antenna Cable2. Connecting the Surge Arrestor and Ethernet / Power cables3. Grounding the System1.2.4.1 Connecting the Antenna CableFollow the following steps to connect an antenna to the device, by using an antenna cable.1. Use an RF cable (antenna cable) to connect the outdoor device to an external antenna.2. Connect the right-angled N-male connector of RF cable on the antenna. The antenna cables run from the external antenna to the N-Type connectors on the device. The N-Type connectors have built-in surge protection.3. Secure the antenna cable to the antenna mast, as the cable connectors do not support the full weight of the cable.4. Connect the other end of the antenna cable to the device.: Do not use tools to tighten the cable connectors, as they damage the antenna cable and connectors.
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 145. If required, adjust the direction of the antenna.6. Tighten the nuts of the antenna to lock the antenna into its position.7. Secure the cable along its complete length with a cable or electrical tape to relieve strain on the antenna connector. No part of the cable should be allowed to hang free, especially the parts that are routed outside the building.8. Weatherproof all the outdoor connectors. See Sealing the Cable Connectors.Ensure you follow the below guidelines while using the antenna cable:•The entire cable used must be secured and no part of the antenna cable should be allowed to hang free, precisely the outdoor cable parts.•The antenna cable and cable connectors are not designed to withstand excessive force.•Do not use the connectors like ‘cable grips’, to pull the cable through raceways or conduits.— Do not use the cable connector to support the weight of the cable during or after installation.— Do not use any tool to tighten the connectors.•Always seal the connectors using the weatherproofing tape.•Avoid any water or moisture entering the cable, as it impacts the performance of the wireless link.•Prior to sealing the outdoor connectors and permanently securing the cable to the wall with cable ties and wall hooks, assure that the components that are installed are functioning properly.Antenna Cable RoutingThe antenna cable must be routed and fixed in such a way, that the installation technicians have a clear passage area. All the connectors that are located outdoor must have a weatherproof seal. We recommend you to seal the connectors only after completing the final radio test. See Sealing the Cable Connectors.1.2.4.2 Connecting the Surge Arrestor and Ethernet / Power cablesPerform the following steps to ensure proper surge protection, and ethernet or power cabling:•Connect the surge arrestor near the outdoor device with a CAT5e ethernet cable (properly ground it near to the cable ingress point of the building, complying with the local electrical code requirements).•Connect the RJ 45 Data In / LAN-IN / IN port on the POE (power injector) and the network interface card of the personal computer with a Cat5e ethernet cable.•Plug one end of the Cat5e ethernet cable into the ethernet port of the surge arrestor (near building ingress point) and connect the other end of the cable to the Data & Power Out / PWR LAN-OUT / OUT port on the POE. Ensure that the cable connector is latched securely.•Connect the remaining ports on both the surge arrestors (one near the outdoor device and other at the building ingress point) with an RJ 45 terminated cable. : It is mandatory to install an approved lightening surge protector at the building ingress point. If the device is installedin a region subjected to violent thunderstorms or severe weather conditions, then installation of an additional: Avoid over-tightening of the connector, nuts and screws that are used to mount the antenna, to protect the antenna and device from getting damaged.IMPORTANT! Ensure to loop the cable before entering the premise to prevent water ingress.
Antenna InstallationTsunami® MultiPoint 10200 Series - Antenna Installation Guide 15approved lightening surge protector near the device is recommended. To buy an additional Surge Protector(Part Number: 235-00001), place an order separately with your distributor. 1.2.4.3 Grounding the SystemDirect grounding of the antenna mast, device, and surge arrestor is extremely important. Refer to the Quick Installation Guide, that comes along with your product, for detailed illustration on grounding the outdoor device and surge arrestors. : A safety grounding system is necessary to protect your radio from lightning strikes and the static electricity generated from it.Grounding the AntennasFollowing precautions should be satisfied, while grounding the antenna:•The antenna mast and the grounding system should be installed only by qualified installation professionals and electrician, who are familiar with local building, safety, and electrical codes in the country of use. •The antenna mast, the device, and the surge arrestor must be connected to the same ground, by using an equi-potential bonding conductor.•A good electrical connection should be made to one or more ground rods, by using at least a 10 AWG ground wire and non-corrosive hardware.1.2.5 Sealing the Cable ConnectorsCorrosion of the antenna cable, cable connectors and other wireless outdoor installations degrade the performance of the wireless link. To avoid, you must always seal the outdoor cable connectors using weatherproofing tape.

The antenna alignment process is usually performed during the installation of the antennas. You can align the antennas by using the following two methods:•Antenna Alignment using CLI Commands•Antenna Alignment using RSSI Light PipeAlternatively, consult an antenna installation service professional to optimize the antenna alignment.(a) (b)(a) (b)

Tsunami® MultiPoint 10200 Series - Antenna Installation Guide 20 2Measuring Signal Performance 2.1 IntroductionThe performance of a microwave link (wireless link established between two outdoor antennas) is closely related to the following factors:•Range•Fresnel Zone•Clearance FactorCalculating the above factors help you align the antennas properly and achieve a better throughput. 2.2 Determining the RangeRange is the maximum distance a microwave link travels and is based on the:•Type of the outdoor antenna equipment (Outdoor antennas differ in technical specifications).•Data speed of the wireless link.•Clearance of the signal path (see Clearance Factor).Use the following formula to determine the range of the microwave link:Range = Maximum Range x Clearance Factor1. Maximum Range: It is the theoretically calculated value achieved under optimal circumstances, by using the available products and their technical specifications that comply with the local radio regulations. The calculations made assuming the optimal radio conditions do not guarantee of achieving the same maximum distance at your location. 2. Clearance Factor: See Clearance Factor.Variations in calculations of the above two factors occur due to any of the following reasons:•Incorrect alignment of antennas.•Polarization mismatch of the antennas.•Sources of interference or unexpected reflections in the signal path that affect the quality of communication (Refer Determining the Optimal Antenna Placement).•Severe weather conditions such as heavy rainfall, snow or strong winds.•Unexpected obstacles in the link path.•Seasonal influences such as leaves on trees or icing of the antennas. 2.3 Fresnel ZoneThe narrow antenna beam emerged from the antennas contain a bulged area called as Fresnel Zone. The first Fresnel Zone is known to be an imaginary boundary line offset along the direct path of the signal, where a signal reflected will travel an additional one-half distance of wavelength. Each succeeding Fresnel Zone boundary adds an additional half-wavelength to the reflected path distance than the direct signal path between the antennas.When any significant part of the Fresnel Zone is obstructed, a portion of the radio energy is lost that results in reduced performance. Reduced performance can also occur when obstacles close to the antenna beam cause signal reflections or noise that interfere with the radio signal. Weather conditions (rain or snow) usually do not have much impact on the performance of your device, provided you have sealed all the cable connectors with weatherproofing tape. Seasonal influence on signal propagation can occur in the following situations:
Measuring Signal PerformanceTsunami® MultiPoint 10200 Series - Antenna Installation Guide 21•Marginal communications quality in late fall (with no leaves on the trees along the signal path) might fail in the summer (with leaves on the trees along the signal path).•In winter, a wireless link can fail when the antenna is exposed to ice buildup or when the antenna elements are covered with snow.Radio paths over water or extremely flat ground require optimization of antenna height at one end. This is due to in-phase or out-of-phase reflections. Adjustment of antenna height by 1 to 3 meters may move the signal from null to peak.Long distance links may be obstructed by earth curvature, so the antenna height requirements must not only take the height of obstructions and Fresnel Zone into account but also the earth bulge. The earth bulge is approximately 5 meters (16.4 ft.) at a link distance of 16 Kilometers (10 millimeters). Consult your supplier to take appropriate steps to maintain or optimize wireless link performance. 2.3.1 Fresnel Zone CalculationThe exact shape and width of the Fresnel Zone is determined by calculating the Fresnel Radius. The distance between the Fresnel Zone boundary and a straight line running along the signal path (shortest path) between the antennas is called the Fresnel Radius. Fresnel Radius can be determined by using the path difference (difference between the shortest path and alternative path) and frequency of the radio signal. If there are no obstacles in the space forming 60% of the path difference, then the propagation characteristics are said to be the same as that in free space.Figure 2-1 Fresnel Zone CalculationLet’s say, in the above figure:–d1 is the distance between the obstacle and the antenna at one end.–d2 is the distance between the obstacle and the antenna at the other end.– is the wavelength of the operating frequency. Then, Path Difference (d3) and Fresnel Radius (rn, radius of the nth Fresnel Zone) can be calculated from the formula below:λ (where n = 1, for the first Fresnel Zone and rn = r1)
Measuring Signal PerformanceTsunami® MultiPoint 10200 Series - Antenna Installation Guide 22The path difference is the required clearance of the antenna beam from obstacles in its path to avoid loss of radio signal. Signals reflected from any even-numbered Fresnel Zone result in signal cancellation while the odd-numbered Fresnel Zones add to the direct path signal. 2.4 Clearance FactorClearance Factor is a correction value (in percentage) that should be used in case, where the signal path of your wireless link does not provide the minimum clearance as listed in the Maximum Range Table. In general, clearance factor is taken as 60% of the Fresnel Zone and is calculated as:Clearance Factor = Fresnel Zone x 60%For optimal performance of your outdoor wireless link, the signal path between the BSU and SU must provide sufficient clearance. Clearance is interpreted as:– The total height above the surface of the earth, in the open areas without obstacles in the signal path. Let’s say antenna is mounted on the roof, then clearance is the total height including the height of the building and the height of the mast above the rooftop.– The height above the highest possible obstacle, in the areas with obstacles along the signal path (path between two antennas).– The height above the rooftop or highest obstacle in the signal path, in dense urban areas. : An outdoor wireless link that lacks sufficient clearance will exhibit poor performance, which is typically perceived as slow network response time. However, your radio equipment automatically retransmits every lost data frame due to an out-of-range situation or frame collision. The larger the number of retransmissions, the lower is the throughput efficiency of your wireless link.Figure 2-2 Clearance required for the Optimal PerformanceAs shown in the above figure, the clearance required for optimal performance is interpreted as:– Vertical clearance above the ground and the highest buildings or objects along the signal path– Horizontal clearance from neighboring buildings and objects along the signal pathFor optimal range and throughput performance, you must ensure that your antenna installation provides maximum clearance in both horizontal and vertical directions.If the local authorities, proprietor of the premises or other miscellaneous factors do not allow you to set up an antenna mast for the clearance requirements, then you may not achieve a full line-of-sight clearance. However, if the distance that your wireless outdoor installation covers is less than the listed maximum range, you don’t need full clearance.To determine the effect of insufficient signal path clearance, you must determine the Clearance Factor and also calculate its effect on the range for your antenna installation, by using the formula described in Determining the Range.
Measuring Signal PerformanceTsunami® MultiPoint 10200 Series - Antenna Installation Guide 23Figure 2-3 Clearance FactorIf the clearance for your antenna installation is equal to or better than the minimum clearance required, then the Clearance Factor for your installation is 100%. If your actual clearance is less than the minimum clearance, then refer the above figure to determine the actual range that applies to the current requirement. : Practically, it is impossible to achieve the maximum range due to the interference from the other radio products.Proxim recommends you to maintain at least 60-70% of the first Fresnel Zone free. If the clearance is lower than this percentage, then the link budget and acquired fade margin are affected. Clearances more than 100% of the Fresnel Zone can cause reflections that are 180 degrees out of phase and can cancel the signal. The Fresnel Zone works in both the horizontal and vertical paths. 2.5 CalculationsA microwave link is established along the path between antennas. Availability of the microwave path is therefore a prediction of the percent of time that the wireless link operates. In the absence of direct interference, availability of microwave path is affected by the following factors:•Path length•Fade margin•Frequency•Terrain (smooth, average, mountainous)•Climate (dry, temperate, humid)Availability of the microwave path can be improved by increasing the fade margin, either by making the path shorter or by using the higher gain antennas in conjunction with lower loss antenna cable (using a higher quality antenna cable, shortening the length, or both).Establish a wireless link for a specific availability rate of microwave path, depending upon the type of information carried over the link and the overall network design redundancy. Let’s say, the data or voice traffic carried by the radio is critical, then the link can be established at a very high availability rate of microwave path (say, 99.999% or 5.3 minutes of predicted outage per year). 2.5.1 Calculating Link BudgetUse the following formula to estimate the received signal level (RSL):RSL (dBm) = Pout - L1+ G1 + G2 - L2 - Lp
Measuring Signal PerformanceTsunami® MultiPoint 10200 Series - Antenna Installation Guide 24where:•Pout is the output power (in dBm) of the transmitter.•L1 is the total loss of all transmission elements between the antenna and the RF device on one side of the link (in dB).•G1 is the gain of the antenna on one side of the link (in dB).•G2 is the gain of the antenna on the opposite side of the link (in dB).•L2 is the total loss of all transmission elements between the antenna and the RF device on the opposite side of the link (in dB).•Lp is the Path loss, defined by: Lp (dB) = 96.6 + 20 log10F + 20 log10D; where:–F is the frequency of the radio system in GHz.–D is the distance of the path in miles. : • This formula is available on a calculation sheet provided by Proxim to generate an estimate of link distance and reliability. • The path loss must be smaller than the link budget minus the minimum required fade margin. The maximum ranges cause the path loss plus the fade margin to be the same as the link budget.The following figure is a pictorial representation of the elements in the Link Budget equation.Figure 2-4 Link Budget Equation-Pictorial RepresentationProcedure1. Start with the transmit power and the number of the channel to be used in dBm. Subtract the total loss of all transmission elements between the antenna and the radio on one side of the link (dB).
Measuring Signal PerformanceTsunami® MultiPoint 10200 Series - Antenna Installation Guide 252. Add the gain of the antenna you will be using. The total is the EIRP (Equivalent Isotropically Radiated Power).3. Determine the path loss of the microwave link by using the mathematical formula of Lp, illustrated in Calculating Link Budget.4. Add the gain of the antenna on the second side of the link.5. Subtract the total loss of all transmission elements between the antenna and the radio on the second side of the link. The result is the Received Signal Level (RSL).6. For details on the receive sensitivity and data rate values used for the wireless link, for details refer to Tsunami® MultiPoint 10200 Series Hardware Installation Guide.7. Subtract this value from the Received Signal Level; this is the Fade Margin. :• The RSL must be higher than the Receiver Sensitivity plus the Fade Margin for a good link. The amount of Fade Margin indicates the reliability of the link. The more the Fade Margin, the more reliable is the link.The results of this link budget calculation are very important for determining any potential problems during installation. If you have calculated the expected RSL, you can verify that it has been achieved during installation and troubleshooting.Tabulated below is the relation between the Distance and Link Budget, for a selected frequency: Reference Frequency: 5600 MHz Center Frequency for EuropeLink Budget (dB)Distance(m)Fresnel Zone (m)Link Budget (dB)Distance(m)Fresnel Zone (m)Link Budget (dB)Distance(m)Fresnel Zone (m)61 4.8 0.3 91 151 1.4 121 4.8 8.062 5.4 0.3 92 170 1.5 122 5.4 8.563 6.0 0.3 93 190 1.6 123 6.0 9.064 6.8 0.3 94 214 1.7 124 6.8 9.565 7.6 0.3 95 240 1.8 125 7.6 10.166 8.5 0.3 96 269 1.9 126 8.5 10.767 9.5 0.4 97 302 2.0 127 9.5 11.368 11 0.4 98 339 2.1 128 10.7 12.069 12 0.4 99 380 2.3 129 12.0 12.7Link Budget (dB)Distance(m)Fresnel Zone (m)Link Budget (dB)Distance(m)Fresnel Zone (m)Link Budget (dB)Distance(m)Fresnel Zone (m)70 13 0.4 100 426 2.4 130 13.5 13.471 15 0.5 101 478 2.5 131 15.1 14.272 17 0.5 102 537 2.7 132 17.0 15.173 19 0.5 103 602 2.8 133 19.0 16.074 21 0.5 104 676 3.0 134 21.4 16.975 24 0.6 105 758 3.2 135 24.0 17.976 27 0.6 106 850 3.4 136 26.9 19.077 30 0.6 107 954 3.6 137 30.2 20.178 34 0.7 108 1071 3.8 138 33.9 21.379 38 0.7 109 1201 4.0 139 38.0 22.680 43 0.8 110 1348 4.2 140 42.6 23.981 48 0.8 111 1512 4.5 141 47.8 25.382 54 0.8 112 1697 4.8 142 53.7 26.883 60 0.9 113 1904 5.0 143 60.2 28.484 68 1.0 114 2136 5.3 144 67.6 30.1
Measuring Signal PerformanceTsunami® MultiPoint 10200 Series - Antenna Installation Guide 26 : The Distance (m) is calculated by assuming the 60% of the 1st Fresnal to be clear.Effective Isotropic Radiated Power (EIRP)In countries like USA and Canada, radio can be installed with any directional antennas gain, as there is no Effective IsotropicRadiated Power (EIRP) limit for the application of these systems for fixed point-to-point applications in the 5.8 GHz frequencyband. In other bands and in other countries, EIRP limits may apply. In the case of EIRP limits, use the lower values of either(Pout - L1+ G1) or the EIRP limit, within the Link Budget equation. You should check this calculation in both the directions toassure legal application. An EIRP limit is the maximum RF energy that can be transmitted as measured at the transmittingantenna and is usually deterwmined by government regulations. For details, we recommend you to refer the Max EIRP valueslisted under the Wireless Interface properties, in the Tsunami® MultiPoint 10200 Series - Hardware Installation Guide.The figure below illustrates the calculation of range through Proxim Link (MP 10xxx) Calculator, available at http://support.proxim.com, that dynamically adapts the transmit power and receive sensitivity values for a selected product to follow the local EIRP rule.
