- Grounding the Antennas Sealing the Cable Connectors Antenna Polarization Aligning the Antenna Audible Antenna Alignment Antenna Alignment using CLI Commands 1.1 Safety Precautions Listed 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. Ensure that the human proximity to the antenna is atleast 50 cm (8 inches) high, avoid the possibility of exceeding the FCC radio frequency exposure limits, during the normal operation of the equipment. Tsunami 800 and 8000 Series - Antenna Installation Guide 7 Antenna Installation 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 Process Follow 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. 7. 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. See Step 4: Next, wrap a layer of the butyl mastic tape on the adhesive side. 11. Align the antennas to establish a wireless link with a better throughput, by using device antenna alignment utilities like Audible Antenna Alignment and Antenna Alignment using CLI commands. See Aligning the Antenna.
: 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 8 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. Antenna Installation 1.2.1 Required Materials The 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 or CAT6 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. 1.2.2 Determining the Optimal Antenna Placement To 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 beam Although, 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 9 Antenna Installation Figure 1-1 Obstacles to be avoided : (a) Neighbouring Buildings (b) Tall Trees (c) Power Lines To 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. 1.2.3 Mounting the Antenna Mounting 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 10 Antenna Installation 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. For 8xxx connectorized unit, use the antenna port A1, if you are using a single polarized antenna. Use the antenna port A1 and A3, if If you are using a dual polarized antenna. For 82x connectorized unit, use antenna ports A1 and A2 for dual polarized antenna.
: As the mounting procedures for the various antennas differ from one another, refer to the guide that comes along with the antenna.
: The antennas installed at both the ends of a wireless link should maintain same antenna polarizations. See Step 4: Next, wrap a layer of the butyl mastic tape on the adhesive side. 1.2.3.1 Antenna Mast Requirements To 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. 1.2.4 Connecting the Cables Once the outdoor antennas are properly mounted, the cable setup essential to complete the outdoor antenna installation is depicted in the following figure:
Tsunami 800 and 8000 Series - Antenna Installation Guide 11 Antenna Installation Figure 1-2 Cable Setup The entire outdoor cabling setup requires the following cabling to be done:
1. Connecting the Antenna Cable 2. Connecting the Surge Arrestor and Ethernet / Power cables 3. Grounding the System 1.2.4.1 Connecting the Antenna Cable Follow 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 for Tsunami 800 and 8000 product series. 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 12 Antenna Installation If required, adjust the direction of the antenna. 5. 6. Tighten the nuts of the antenna to lock the antenna into its position.
: 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. 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 Routing The 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 cables Perform the following steps to ensure proper surge protection, and ethernet or power cabling:
Connect the surge arrestor near the outdoor device with a CAT5e/CAT6 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 LAN-IN port on the POE (power injector) and the network interface card of the personal computer with a CAT5e/CAT6 ethernet cable. Plug one end of the Cat5e/Cat6 cable into the ethernet port of the surge arrestor (near building ingress point) and connect the other end of the cable to the PWR-LAN-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.
: Proxim recommends two approved lightning surge protectors to be installed, one near to the device and the other at the building ingress point. To buy an additional Surge Protector (with Part Number: 235-00001), place an order separately with your distributor. Tsunami 800 and 8000 Series - Antenna Installation Guide 13 Antenna Installation
: The surge arrestor and the antenna mast must be connected to the same grounding system, by using the shortest cable possible, as prescribed by local electrical codes. 1.2.4.3 Grounding the System Direct 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 Antennas Following 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 10AWG ground wire and non-corrosive hardware. 1.2.5 Sealing the Cable Connectors Corrosion 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. To weatherproof the antenna connectors at both the ends of a wireless link, follow the following step-by-step procedure:
1. Collect the required material:
The material required for weatherproofing connectors are, Any standard Butyl Mastic Tape Any standard Vinyl Tape We have used the following Butyl Mastic Tape and Vinyl Tape as an example to demonstrate the weatherproofing steps:
2. Follow the following weatherproofing steps:
: We have taken MP-8100-BSU and 16 dBi dual polarized sector antenna as an example to explain the weatherproofing steps. Follow the same method to weatherproof the antenna connectors of the Tsunami 800 and 8000 series products.

If you are using a single polarized or dual polarized antenna, it is recommended to terminate the unused antenna ports with an N-male 50 ohm terminator (supplied with the product package). Refer Tsunami 800 and 8000 Series
- Hardware Installation Guide, for details. Tsunami 800 and 8000 Series - Antenna Installation Guide 18 Antenna Installation Consider mounting the antenna for horizontal polarization and minimize the influence of cross-talk between antennas, only under the following circumstances:
When you are using single polarized antennas at both the ends of a wireless link. When multi-directional antennas are mounted to the same mast. When the wireless link receives interference from a vertically polarized antenna in the vicinity. 1.2.7 Aligning the Antenna Antenna alignment is the process of physically aligning the antenna of the radio receiver and transmitter to establish a link with a better throughput. The antenna alignment process is usually performed during the installation of the antennas. You can align the antennas by using the following two methods:
Audible Antenna Alignment Antenna Alignment using CLI Commands Alternatively, consult an antenna installation service professional to optimize the antenna alignment. 1.2.7.1 Audible Antenna Alignment The device has a built-in audible antenna alignment tool that can be activated by plugging in the supplied RJ11 serial dongle. It is audible up to a distance of 30 meters. The CLI command enables both audible and numerical feedback as the CLI shows the running Signal-to-Noise Ratio (SNR) values twice a second. The output from the beeper consists of short beeps with a variable interval. The interval changes with the SNR level to assist in correctly aligning the antenna. An increase in signal level is indicated by a shorter interval between beeps and a reduction in signal level results in longer beeps. The alignment process averages the SNR, which is represented by an average length beep. When a higher SNR is received, the beep period becomes shorter, dependent upon the difference to the average. A lower SNR results in a longer period between beeps. Figure 1-3 Beep Interval When the antenna is aimed, the beep intuitively represents whether the SNR is rising or falling. The higher the SNR rises, the higher is the frequency of the beep and shorter beep is heard. When you change the position of the antenna, SNR averaging settles at the new value and the beeping returns to the average length so the antenna can again be aimed for rising SNR. Aiming is complete if moving the antenna in any direction results in a falling SNR value (which can be heard as longer periods between beeps). Tsunami 800 and 8000 Series - Antenna Installation Guide 19 Antenna Installation
:
The range of the average SNR is limited to values from 5 to 43. Anything over 43 always results in a short period between beeps and values below 5 always have a long period. The Antenna Alignment Display (AAD) CLI command is automatically disabled 30 minutes after it is enabled to remove the load of extra messages on the wireless interface. The default telnet time-out is 300 seconds (5 minutes). It is applicable only to 8xxx devices. 1.2.7.2 Antenna Alignment using CLI Commands To enable the antenna alignment display from the CLI prompt, enter the following commands:
aad enable local: Enables display of the local signal, noise and SNR. aad enable remote: Enables display of the remote signal, noise and SNR. aad enable: Enables display of local and remote signal, noise and SNR.
: Use a flat blade screw driver to disconnect and pull out the serial cable from the enclosure after the antenna alignment is done. After withdrawing the cables, seal the serial port carefully to avoid water seepage.

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 Factor 1. 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 (Refer to Aligning the Antenna). 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 21 Measuring Signal Performance 2.3 Fresnel Zone The 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:
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 Calculation The 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 Calculation Tsunami 800 and 8000 Series - Antenna Installation Guide 22 Lets say, in the above figure:
Measuring Signal Performance 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:
(where n = 1, for the first Fresnel Zone and rn = r1) The 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 Factor Clearance 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. Lets 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 Performance Tsunami 800 and 8000 Series - Antenna Installation Guide 23 Measuring Signal Performance As 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 path For 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 dont 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. Figure 2-3 Clearance Factor If 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 Figure 2-3 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 24 Measuring Signal Performance 2.5 Calculations A 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. Lets 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 Budget Use the following formula to estimate the received signal level (RSL):
RSL (dBm) = Pout - L1+ G1 + G2 - L2 - Lp where:
Pout is the output power (in dBm) of the transmitter. 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). L1 is the total loss of all transmission elements between the antenna and the RF device on one 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. Tsunami 800 and 8000 Series - Antenna Installation Guide 25 The following figure is a pictorial representation of the elements in the Link Budget equation. Measuring Signal Performance Figure 2-4 Link Budget Equation-Pictorial Representation Procedure 1. 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). 2. Add the dBi 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, please refer to the Tsunami 800 and 8000 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.

Tsunami 800 and 8000 Series - Antenna Installation Guide 27 Measuring Signal Performance 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 Isotropic Radiated Power (EIRP) limit for the application of these systems for fixed point-to-point applications in the 5.8 GHz frequency band. 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 to assure legal application. An EIRP limit is the maximum RF energy that can be transmitted as measured at the transmitting antenna and is usually determined by government regulations. For details, we recommend you to refer the Max EIRP values listed under the Wireless Interface properties, in the Tsunami 800 and 8000 Series - Software Management Guide. The figure below illustrates the calculation of range through Proxim Link (MP/QB 81XX) Calculator, available at http://
my.proxim.com, that dynamically adapts the transmit power and receive sensitivity values for a selected product to follow the local EIRP rule.
