However, SU The BSU and SU integral antennas use left-hand models 40100-xxxC and BSU models 40400-xxC circular polarization (LHCP). External antennas replace the integral antennas with a type-N with either linear or circular polarization can be female connector, letting you purchase and use considered. Use the following guidelines to antennas better suited for your particular assist in your planning. application, if so desired. Planning for Antenna Installation In general, the larger the antenna used with the radio, the better the link performs. Larger antennas have narrower beamwidth and higher gain, which yield better link performance (higher fade margin, better availability) and improve immunity to interference. However, larger antennas are more costly to purchase and install than smaller antennas and, in some cases, require special installation equipment and more robust mounting structures (due to increased weight and wind loading). 1. The polarization of the BSU and SU antennas should be of the same type. For a given polarization, the same polarity (vertical ir horizontal) must be used at each end of the link. 2. Linear and circular polarization can be used at opposite ends of the link; however, this results in a 3 dB loss in signal strength. 3. Integral antenna units and external antenna units can be used in the same sector. 4. Only LHCP antennas can be used with SUs connecting to a BSU with Active Interference Rejection (A.I.R.). Base stations, however, require wide Note: The A.I.R. BSU is compatible only with LHCP beamwidths in azimuth so that a large segment of subscribers can be accessed spatially. Antennas are available to allow sectors ranging from 30 to 360. Of course, the larger the sector, the less antenna gain for longer transmission distance and interference immunity. signals from SUs. SUs must use LHCP antennas; either the integral antenna or an LHCP external antenna. You should consider all of these factors when selecting an antenna. This advanced planning also yields the transmission line requirements. 4 Draft Date: 02/25/03 Connecting External Antennas to the BSU and SU CPN 000000 The following tables list antenna types, performance, and manufacturers.

The transmission line should be kept as short as possible so, when line-of-sight placement of antennas allow flexibility, it is always desirable to locate the equipment closer to the antenna. Within the USA and Canada, antennas other than those illustrated in these tables can be used with this radio, but must be of the same type (flat panel or solid parabolic), dimensions, and gain as those listed in the table. Antennas with gain less than 7.5 dBi are not approved for Verify configuration settings (through the BSU Console) for proper configurations. Verify that the SU enters the network. Connect to services, if possible, to verify network connection and configurations. 2. Mount Antennas Antenna height can be critical for path clearance and line of sight. Ensure that antennas will not be blocked by use within the USA or Canada. Consult people. governmental regulations or Proxim Corporation for applications outside of the USA or Canada. For further information regarding antenna installation and adjustment, see Installing and Adjusting the Antenna later in this section. Note:

of 17 dBm and 36 - G + L Max BSU Tx (dBm) is the lesser G is the antenna gain and L is the transmission line loss. Reviewing the Installation Process The following is an overview of the installation process to assist you in your planning activities. 1. Test Radios Back-to-Back and Configure Use at least 60 dB and no more than 80 dB attenuation and a short low-loss RF transmission line to connect the two radios. Apply power. 6 Draft Date: 02/25/03 Antenna structure must be secure for wind load and whatever climbing may be necessary. 3. Run Transmission Line Route and Egress, including Lightning Arrestors Use proper transmission line. Proper termination is critical, especially at 5.8 GHz. Be careful with the bend radius and never kink the transmission line. Secure transmission line to structures; be careful not to crush. A direct connection to the antenna feed is ideal (if required, you can use a flexible jumper at the antenna, a properly specified 90-degree connector/adaptor, or both). Weatherproof all outdoor connections when completed with installation. If the transmission line is longer than three meters, a lightning arrester located near the RF Unit is recommended. If the RF Unit is Connecting External Antennas to the BSU and SU CPN 000000 located indoors, locate the lightning arrestor at the building egress point.

Connect Radios to Antennas and Power, including Grounding Connect to RF transmission line from antenna directly or using flexible jumper, if necessary. Do not use 90 adapters unless rated at operating frequency. Connect CAT5 cable from power adapter to BSU/SU. Test power voltages and pinouts before connecting power to BSU/SU. 5. Align Antennas Rough align antenna azimuth and elevation based upon path planning (using compass bearing or milestone sighting, telescopic sight, binoculars, and so on). Use the audio indicator to align the SU antenna, or the received signal quality indicator display of the SU Utility software to peak antennas. Adjust alignment of one antenna at a time, one plane (azimuth versus elevation) at a time. Adjust each end multiple times until predicted RSL is achieved. Connecting External Antennas to the BSU and SU CPN 000000 7 Draft Date: 02/25/03 Establishing Connections Antenna Connection The BSU and SU radios are equipped with an N-

type female connector at the antenna port. You can use a short length jumper cable (such as - to -inch coax or pigtail of approximately 6 feet in length) fitted with two N-type male connectors to connect the antenna port to the antenna (if the unit is located near the antenna) or to the primary transmission line (if the unit is mounted remotely from the antenna). A low-loss 50-ohm cable is recommended for the antenna transmission line between the BSU/SU and the antenna (such as Andrew LDF4-50 or Times LMR-600 1/2-inch coaxial cable, an Andrew LDF4.5-50 or Times LMR-900 5/8-inch coaxial cable, or an EW-52 waveguide). The return loss presented by the transmission line at the BSU/SU interface should be as high as possible (20 dB minimum recommended). The length of the antenna transmission line should be kept as short as possible to minimize loss. 8 Draft Date: 02/25/03 Antenna Cabling Guidelines for 5.8 GHz Units Coaxial cables of 7/8-inch or larger diameter can exhibit moding at 5.8 GHz and are never recommended. Also, some small diameter cable types, such as RG-8, have high loss or poor VSWR at these frequencies. If small diameter cables are required, be certain to keep the lengths of these cables as short as possible. For wave guide transmission line at 5.8 GHz, EW-52 wave guide is recommended. EW-63 also works, but exhibits more loss. Do not use right-angle N-type connectors with the BSU/SU radios operating at 5.8 GHz unless the connector has been specifically rated and tested up to 5850 MHz. Unless specifically designed for these frequencies, these connectors can present high loss at these frequencies. Do not use low quality jumper cables with the radios. Always precisely follow manufacturers recommended procedures and tools for termination. BSU/SU RF Connections Prepare the RF transmission line feeder cable as follows:

1. Cut the cable to the approximate length

(allowing some excess). 2. Install the appropriate connector on the antenna or BSU/SU end: Place tape or a covering over the connector end so that debris cannot harm the connector. Connecting External Antennas to the BSU and SU CPN 000000 3. Pull the transmission line through the cable Be sure to use manufacturer-specified ducts, trays, or conduit (as required) to the connectors and termination tools, and follow antenna, while being careful not to kink or termination instructions precisely. Improper damage the transmission line in any way. transmission line terminations can cause Note: RF transmission line must never be bent, twisted, or deformed in any way. Pay close attention to the transmission line excess losses and reflections that can lead to many problems with the system. 8. Prior to operation, check the electrical specifications for bend radius when installing. integrity of the transmission line, including 4. Support the transmission line in a tray on horizontal runs and by hangers on vertical runs. Space hangers according to the manufacturer instructions (typically every five feet under conditions of no ice and not greater than 85 mph winds). 5. Ground the transmission line using the manufacturer grounding kit. Grounding kits attach to the outer copper conductor. Install grounds at the antenna, at the bottom of the antenna structure (if applicable), and where the transmission line enters the building. Be sure to ground long transmission line runs every 100 feet. 6. Lightning suppression (such as Polyphaser LSX) is required at the interconnection cable junction as close as possible to the BSU/SU when the cable is longer than 3 meters. There should always be a lightning protection device at the egress point for whatever cables egress the building or enclosure. Lightning arrestors must be properly grounded to operate. 7. After installation, terminate the transmission line with an N-type male connector or adapter attached at the equipment end. For wave guide, this typically requires a CPR-to-

N adapter. all connectors, with a simple DC check between the center conductor and outer conductor (this is neither possible, nor required for wave guide). The transmission line ideally should be connected directly to the antenna at one end and to the BSU/SU antenna port at the other end (through the RF Lightning arrestor). However, short pigtail jumper cables may be required to avoid sharp bends in the primary transmission line to limit stress on either connection. 9. Connect the transmission line to the RF connector on the BSU or SU. Create a drip loop in the cable as shown in the figure below, and tie the cable to the mast or pole to remove any stress on the RF connector. The drip loop allows any moisture on the wires from rain or condensation to drip off. photo]

Constructing Power and Ethernet Cables in the Tsunami Multipoint Installation Manual for instructions. Installing and Adjusting the Antenna The installation information discussed in this section is generic. For installation procedures specific to the antenna you are installing, refer In cases of indoor installations, ensure that the antenna location is restricted and bear in mind the RF exposure requirements of the warning statement above. Antennas should be:

Ordered with the suitable mounting kit specific to the site requirements. Very rigidly mounted, with adequate room for azimuth and elevation adjustment from to the antenna manufacturers documentation. the rear. Antenna Installation

(FCC requirement for implementation in the USA) WARNING Antennas used for the transmitter must be fix-

mounted on outdoor permanent structures with a separation distance of at least 2 meters from all persons during normal operation. Antennas must be professionally installed. Installers must be provided with antenna installation instruct-

tions and transmitter operating conditions, including antenna co-location requirements of CFR47 Part 1.1307(b)(3), for satisfying RF exposure compliance. Antenna installation consists of permanently mounting the antenna to the mast, pole, or tower and then attaching the RF Unit (BSU or SU) to it. The antenna and RF Unit must be mounted outdoors on a tower, building roof, or other location that provides line-of-sight path clearance to the far-end location. In some cases, the antenna can be mounted indoors, behind a window; however, RF attenuation through windows can vary greatly, depending upon the glass and any coatings that might be present, plus the precise location and angle of the antenna relative to the window. The antenna polarization must be the same at both ends of the link, either vertical or horizontal. In general, antenna mountings require a support pipe to which upper and lower support brackets are attached with U-bolts. The antenna and optional elevation and azimuth adjustment rods are then mounted onto the support brackets. The entire structure must be adequately grounded for lightning protection. The antenna system must always be installed according to the manufacturer's instructions. Alignment Guidelines When aligning antennas, if the SU is located indoors or distant from the antenna location, you may want to use a cellular telephone or two-way radio for relaying signal strength information from the SU Utility software to the antenna alignment location. Similarly, a cellular telephone or two-way radio can be used to relay received signal strength information at the SU to the BSU alignment end. 10 Draft Date: 02/25/03 Connecting External Antennas to the BSU and SU CPN 000000 It is critical that antenna alignment be When fine-aligning the BSU elevation:

Adjust the elevation of the BSU antenna to maximize the RSL indication at the SU. Align the far-end antenna in the same manner, using the SU RSL indication. Multiple SU locations may be used to improve the quality of the BSU antenna In some cases, you may need to perform coarse adjustment. alignment using a wide arc in both azimuth and elevation while reading the RSL to find the main beam of the opposite end antenna.

About This Book CPN 63179 6 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Chapter 1. Site Planning The installation of a wireless network requires much the same basic planning as any wired network. The main difference is that the wireless signal requires some additional planning. This planning includes RF path planning, site preparation, and installation of outdoor components, such as outdoor units, antennas, lightning protection devices, and cabling suitable for outdoor conditions. Although the technology implemented in this broadband fixed wireless system can make use of multi-

path signals to reduce the effect of obstructions in the path, the characteristics of the path must be carefully examined. With this knowledge, components and network requirements can be correctly planned for your specific application. This section provides insight into the planning necessary to prepare your site for your broadband fixed wireless system. General Considerations A basic consideration is the physical location of the sites at each end of the link. Because microwave signals travel in a straight line, a clear line-of-sight between antennas is ideal. Frequently, however, the locations of the desired links are fixed. When you cannot achieve a clear line-of-sight, you must plan accordingly. Other general site considerations include:

Whether a tower must be constructed (and whether permits are required) Possibility of future obstructions Will trees grow high enough to interfere with the signal? Are there plans to erect buildings between the sites that may obstruct the path?

Availability of grounding Good grounding is important. Also, in areas prone to lightning, a lightning arrestor is strongly recommended. Distance between the indoor portion of the system and the users network. Whether the SU may potentially be served by different BSUs. Prior to installation, try to determine the best BSU access and available sighting location. Whether strong RF interference exists in the neighborhood, within or adjacent to the operating frequency. The following sections are provided to help you determine which information is critical to your site, and to aid in the decision-making process. Chapter 1. Site Planning CPN 63179 7 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Specific Considerations Weather You should research any unusual weather conditions common to the site location. These conditions can include excessive amounts of rain, wind velocity, or extreme temperature ranges. If extreme conditions exist that may affect the integrity of the radio link, take these conditions into consideration early in the planning process. Rain Except in extreme conditions, attenuation (weakening of the signal) due to rain does not require serious consideration for frequencies up to the range of 6 GHz. When microwave frequencies are at the 10-12 GHz range or higher, attenuation due to rain becomes much more of a concern, especially in areas where rainfall is of high density and long duration. The systems discussed in this manual operate at frequencies below 6 GHz, so rain is not a concern. Temperature Temperature can adversely affect the radio link when phenomena such as temperature inversion or very still air accompanied by stratification occur. Temperature inversion can negate clearances; still air, along with stratification, can cause severe refractive or reflective conditions, with unpredictable results. Temperature inversions and stratification can also cause ducting, which may increase the potential for interference between systems that do not normally interfere with each other. Where these conditions exist, you should use shorter paths and adequate clearance. Wind Any system components mounted outdoors are subject to the effect of wind. You should know the direction and velocity of the wind common to the site. Antennas and their supporting structures must be able to prevent these forces from affecting the antenna or causing damage to the building or tower on which the components are mounted. Antenna designs react differently to wind forces. This is known as wind loading. BSU and SU Wind Loading Maximum operational wind speed during operation of BSUs and SUs is 50 m/s (112mph). Survivable wind speed (tested to equivalent speed) is 90m/s (200mph). The wind loading effect of the BSU and SU on their respective mounting masts is provided in Figure 1

(BSU) and Figure 2 (SU). The units of force in pounds can be converted to metric units by multiplying by Chapter 1. Site Planning CPN 63179 8 Issue Date: 01/24/03

Similarly, foot-pounds can be multiplied by 1.36 to obtain Newton-meters, or by 0.138 to obtain kgm-meters. Note: For definitions of wind loading specifications for antennas and towers, refer to TIA/EIA-195 (for antennas) or TIA/EIA-222 (for towers) specifications. Figure 1. BSU Wind Loading Analysis Figure 2. SU Wind Loading Analysis Chapter 1. Site Planning CPN 63179 9 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Lightning You should always consider the potential for lightning damage to radio equipment when planning a wireless link. A variety of lightning-protection and grounding devices are available for use on buildings, towers, antennas, cables, and equipment that could be damaged by a lightning strike, whether located inside or outside the site. Lightning protection requirements are based upon the exposure at the site, the cost of link down-time, and local building and electrical codes. If the link is critical and the site is in an active lightning area, attention to thorough lightning protection and grounding is critical. Lightning Protection To provide effective lightning protection, install antennas in locations that are unlikely to receive direct lightning strikes, or install lightning rods to protect antennas from direct strikes. Make sure that cables and equipment are properly grounded to provide low-impedance paths for lightning currents. Install surge suppressors on adjacent telephone lines and power lines. Users should provide additional lightning protection for cables leading to the wireless radio as well as to and from the power supply in regions that have extreme lightning occurrences. This optional lightning protection should be placed at points close to where the cable passes through the bulkhead into the building, as well as near the BSU/SU. A grounding screw is provided on the BSU and SU. For indoor applications, you can use the Erico LAN-RJ45 Local Area Network Protector (see Ericos web site, http://www.erico.com for information); for outdoor applications, you can use lightning protectors from PolyPhaser (see the Polyphaser web site, http://www.polyphaser.com ). See Appendix E. Lightning Protection Recommendations on page 70 for more information. Category 5 Cable When the entire power and Ethernet cable is encased in steel conduit from the building entrance to the radio, no surge arrestors are required. Otherwise, each power and Ethernet cable requires one surge arrestor within two feet of the building entrance. Interference and How to Avoid It An important part of planning your broadband fixed wireless system is the avoidance of interference. Interference can be caused by effects outside the system. Good RF planning can overcome most interference challenges. Note: The Tsunami Multipoint product line includes a BSU that provides spectrum shielding. This BSU model can reject interference at the uplink location. If interference from other systems is a problem, Proxim recommends you use a BSU equipped with this feature. Chapter 1. Site Planning CPN 63179 10 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Co-Channel and Adjacent Channel Interference Co-channel interference results when another RF link is using the same channel frequency. Adjacent-

channel interference results when another RF link is using an adjacent channel frequency. In selecting a site, a spectrum analyzer can be used to determine whether any strong signals are present and, if present, determine how close they are to the desired frequency. The further removed from your proposed frequency, the less likely they are to cause a problem. Antennas Antennas frequently play a key role in reducing the potential for interference. They come in a variety of configurations that have different performance characteristics in the areas of gain and direction. Antennas that transmit/receive in all directions are known as omni-directional, while those that transmit/receive in one specific direction are categorized as directional. Antennas also vary in beamwidth, which is the aperture to which they can see signals. Larger antennas typically provide narrower beamwidths and can diminish interference from nearby transmitters by:

Focusing RF energy from the intended destination Reducing the power of interfering sources not directly aligned to the antenna Tsunami Multipoint Ethernet Systems use integrated directional antennas that transmit and receive a relatively narrow beamwidth of radio energy, improving system performance by reducing the likelihood that surrounding RF clutter will interfere with reception. The antennas with this system are directional and cannot be detached. Chapter 1.

LHCP Beamwidth (Azimuth/Elevation): 10-degree Figure 5. SU Antenna Pattern Even when other licensees are not an issue, if you are using a network deployment using the cell approach, all these considerations are still important for reducing interference between your own adjacent installations. Antennas are tuned to operate on a specific group of frequencies. Antenna Polarization The Tsunami Multipoint system uses left-hand circular polarization. As a result, the signal is successfully received regardless of the orientation of the antenna. Circular polarization also provides protection against multi-path degradation of the signal quality. Towers When planning antenna placement, it might be necessary to build a free-standing tower for the antenna. Regulations and limitations define the height and location of these towers with respect to airports, runways, and airplane approach paths. These regulations are controlled by the FAA. In some circumstances, the tower installations must be approved by the FAA, registered with the FCC, or both. To ensure compliance, review the current FCC regulations regarding antenna structures. These regulations (along with examples) are on the FCC web site at http://wireless.fcc.gov/antenna/ . Chapter 1. Site Planning CPN 63179 13 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Path Planning To get the most value from a wireless system, path planning is essential. In addition to the fact that radio signals dissipate as they travel, many other factors operate on a microwave signal as it moves through space. All of these must be taken into account, because any obstructions in the path can attenuate the signal. Calculating a Link Budget A link budget is a rough calculation of all known elements of the link to determine whether the signal will have the proper strength when it reaches the other end of the link. To make this calculation, consider the following information. A signal degrades as it moves through space. The longer the path, the more loss it experiences. This free-space path loss is a factor in calculating the link viability. Free-space path loss is easily calculated for miles or kilometers. Availability represents the quality of a link. It is the ratio of the time that the link is available to the total time. This serves as a guide to the service you can expect, on the average, over a period of one year. You can lower the bit error rate (BER), resulting in greater reliability, by reducing the data throughput or reducing the distance between the BSU and the SU. Note:

In terrestrial communication, path loss does not necessarily follow 20dB per decade degradation as used in free-space loss. Instead, 25-35 dB per decade is more common in a metropolitan near-line-of-sight environment. Unlicensed Frequencies (U-NII) The FCC has identified the frequencies from 5.725 to 5.825 GHz as Unlicensed National Information Infrastructure (U-NII). This band can be used by anyone without having to obtain a license. However, you must use radio equipment that is type approved by the FCC or local government for use within the specific band. PMP Radio Information The following sections provide information about the Tsunami Multipoint radio components. See Appendix C. Technical Specifications on page 57 for product technical specifications. Chapter 1. Site Planning CPN 63179 14 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Channel/Frequency Plans Tsunami Multipoint offers several frequency plans to provide a means for overcoming interference. If one part of the 5.8 GHz spectrum is occupied when you deploy the product, you can select a different frequency plan to bypass the interfering frequency. Plan 4 is the default. Operating frequencies in the 5 and 6 plans overlap. See Change the Frequency Plan and Operating Frequency on page 50 for more information. Bandwidth The Tsunami Multipoint offers four modulation modes: QAM16 (60 Mbps), QAM8 (40 Mbps), QPSK3Q (30 Mbps), and QPSK1H (20 Mbps) with equal bandwidth occupancy (3 dB BW at 20.75MHz, 26dB BW at 26MHz). Downlink and uplink signals are divided into time slots, with the number of slots per frame varying, depending upon the current modulation mode and data rate. Furthermore, the ratio of slots assigned to downlink and uplink is commandable (within limits; see setFirstInboundSlot in the Tsunami Multipoint Version 1.3 Reference Manual for details) Tx Power and Antenna Specifications See Tx Power, txPowerLevel, and Antennas in the Tsunami Multipoint Version 1.3 Reference Manual. Power Control Each SU automatically adjusts its transmit power so the strength of its signal at the BSU does not exceed the limitation imposed by the Inbound Power Control (IPC) margin. This ensures fair access for all SUs regardless of distance from the BSU. In addition, IPC can be increased to overcome interference. See the IPC command in the Tsunami Multipoint Version 1.3 Reference Manual for more information. Chapter 1. Site Planning CPN 63179 15 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Chapter 2. Deploying the Base Station Unit (BSU) This chapter describes how to mount and deploy the Base Station Unit including the GPS Antenna

(required when you install multiple BSUs at the same location). Unpacking the System The products shipping boxes should be left intact and sheltered until arrival at the installation site. If the shipping container shows signs of damage, immediately notify the transportation company. Upon receipt, inspect contents to make sure no parts are missing or damaged. Proxim recommends that you retain all the packaging materials (including all internal boxes). In the unlikely event that the equipment must be returned to the factory, use the original packing materials for return shipment. The packaging materials are also recommended for transporting the equipment from location to location. Unpack the following items from the contents of the shipping box. In addition to these items, you will require an additional Cat 5 cross-over or straight-through cable (see step 5) and a BSU power adapter

(the BSUs power supply is ordered and shipped separately; the power supplys CPN number is 58526). Figure 6.

(In this configuration, the BSU points down when mounted on a pole.) 7. Attach the other 1/2-13x7 1/2 screws/clamp bracket assembly to the downtilt bracket using two sets of 3/8-16x1 1/4 hex head screws, #3/8 split lock washers, and 3/8-16 hex nuts (see Figure 12). Figure 12. Screws/Clamp Bracket Assemblies Attached Chapter 2. Pre-Installation Tasks CPN 63179 20 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Mounting the BSU to a Pole To mount the BSU to a pole using the attached mounting components:

1. Lash the unit to the pole or use a hoisting rope to keep the unit in place while you mount it. Slide the two strap clamps over the two sets of 1/2-13x7 1/2 screws and secure the strap clamps using four

#1/2 split lock washers and four 1/2-13 hex nuts (see the following photo). Figure 13. Strap Clamps Attached and Mounted BSU 2. To adjust the up/down tilt (-10 to +5 degrees), move the top or bottom of the BSU (depending on how you installed the downtilt/notched bracket assemblies) until the unit is roughly positioned at the correct angle. 3. Connect the supplied Cat 5 cable to the BSUs Power and Ethernet port as described in the following notes. Then screw on the outer ring to secure the cable in place. Figure 14. BSUs Power and Ethernet Connector Chapter 2. Pre-Installation Tasks CPN 63179 21 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide The Base Station Unit (BSU) is shipped with a dust cover over the large 18-pin connector. Keep this cover on until ready to mate with cable connector to avoid getting the connector wet. To ensure proper weatherproofing, follow these procedures to connect the supplied Cat 5 cable to the BSUs Power and Ethernet port. A. Check the BSU connector. The only moving part should be the plastic nut (B), which screws onto the BSU housing. B. If there is any movement or play between parts A and C, you must tighten these parts before proceeding; otherwise you could cause connector pins to disconnect or break when you apply the weatherproofing tape. To tighten, first loosen (but do not remove) the connectors screws (indicated with arrows in the previous figure). C. Then, while holding the pin connection portion (1), turn the bottom portion (2) clockwise until there is no more movement, making sure you do not over-tighten. D. Re-tighten the screws. E. When mating the BSU to the cable connector, first apply a bead of silicone grease or RTV to the 3mm-wide outward-most flange on the BSU connector (or in the outer ring of the cable-

end mating connector). F. Then tighten the plastic nut on the cable end to 16 inch-lbs (1.81 N-m). The cable connector must be tightened onto the BSU sufficiently to compress a small O-ring that resides inside the male BSU connector. If the O-ring is missing or insufficiently compressed, moisture can get through into the connector pins. Chapter 2. Pre-Installation Tasks CPN 63179 22 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Once mated, over-wrap the connectors (as demonstrated in the following table) with stretchy black self amalgamating tape (such as CTB-15 CATV TAPE-X5-BK-UN part #22150000 from DSG CANUSA 173, Commerce Boulevard, Loveland, Ohio 45140, Tel. 1-800-422-6872) to ensure a better water seal. 1) 3) 5) 2) 4) 6) 4. Connect the other end of the Cat 5 cable to the BSUs power supply. (The BSUs power supply is ordered and shipped separately. The power supplys CPN number is 58526.) 5. Plug the power supply into an electrical outlet. Note: To ensure proper grounding, use the hole on the back of the BSU and the provided grounding screw to attach a ground wire to the BSU. Use wire grounding techniques in accordance with your local electrical codes. Chapter 2. Pre-Installation Tasks CPN 63179 23 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Installing the GPS Antenna If you do not plan to install multiple BSU in the same geographical area skip this section If you plan to install multiple BSUs in the same geographical area (for example, one BSU might interfere with another), you must install the supplied GPS antenna (a small metal plate with a black 2"x 2"

antenna and thin cable) on each BSU. Each BSU uses a global positioning system (GPS) to synchronize its clock with other BSUs. You also must set each BSU to Multi Sector mode (see Configuring the System for Multi-Sector Mode on page 29). Mounting the GPS Antenna To install the GPS antenna:

1. Position the GPS antenna in a location where the antenna plate is parallel to the earth/horizon and the black antenna bump-up can be attached to the BSU (as shown in the following figure). The GPS antenna should be exposed to as much of the sky as possible so it can acquire at least four GPS satellites to extract timing signals for the BSU transmission synchronization. Figure 15. GPS Antenna Mounted on BSU 2. Insert the band clamp through the slots in the GPS antenna-unit mounting bracket and around the mounting pole. Tighten the clamp around the mounting pole and then tighten the screw in the clamp to secure the GPS antenna mounting bracket to the mounting pole. 3. Attach the GPS antenna to the GPS antenna mounting bracket using the #10-32x3/8 SEM screws

(the screws with attached washers). Chapter 2. Pre-Installation Tasks CPN 63179 24 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 4. Remove the water-protection cap from the top of the BSU and screw on the cable from the GPS antenna to the connector on the top of the BSU. Installing BSU Configuration Software The next step is to configure the BSU. The BSU is configured from a PC running the BSU Configuration Software (Versions 1.4 or 1.5). This PC communicates with the BSU through its Ethernet port. If you have a PC with the BSU Configuration Software already installed, skip to Configuring the Base Station on page 26; otherwise, install the BSU Configuration software as described in Appendix B. Installing the Software and Upgrading Firmware on page 51. Operating in a Test Environment Prior to installation outdoors, you may want to operate the equipment indoors in a test environment to become familiar with the operating configurations and performance. Furthermore, in situations in which it is extremely difficult (very low temperature) or costly (on a mountain top) to install or replace the equipment, you may want to verify operation in an indoor test environment prior to actual installation in the field. All of the configuration and testing information described in the previous chapters, with the exception of the actual mounting of the units, apply to an indoor test deployment. The following sections describe a procedure to set up a pre-installation testing environment for this purpose. Warnings and Considerations for an Indoor Deployment Review the following important warnings and considerations before turning on any Tsunami Multipoint equipment indoors in your test environment. WARNING! All persons should be at least 5 feet (1.5 meters) away from any antenna when any products are operational. Place the antennas at least 30 feet apart, facing each other. To minimize the multi-path phenomenon, the BSU should be configured to use the lowest transmit power level (6 dBm) and the most reliable modulation technique (20 Mbps mode). In addition, the BSU must have GPS and Range Security disabled. Also, make sure the BSU is facing toward the SU. Do not set up your laptop between the antennas or stand between the antennas. Try to minimize the movement of objects within the test environment to prevent changes in radio propagation patterns. Radio signals behave differently indoors than outdoors; using the devices indoors may have an unintended, negative effect on the performance of the Tsunami Multipoint system. For best results, connect at least one computer to the BSU and to each SU. Chapter 2. Pre-Installation Tasks CPN 63179 25 Issue Date: 01/24/03

Tsunami Multipoint Version 1.3 Installation Guide Install the BSU first before installing any SUs. Once a link has been established, check the RSL at the SU, and if too high, miss-point the antenna slightly to reduce the receive power. Configuring the Base Station Keep in mind the following when configuring a BSU:

The configuration commands are NOT case-sensitive. Refer to the Operator Commands section of the softwares Help menu (or the Reference manual) for additional information on command syntax. The BSU does not provide an on-screen response to many of the available commands. The BSU saves the configuration settings periodically (approximately every two minutes). Therefore, after issuing the last configuration change, wait two minutes before recycling power or turning off the unit to ensure that all of your changes take effect. To configure the Base Station:

1. On the computer that has the Base Station Configuration Software installed, change the IP address for its Ethernet card to 192.168.20.xx with a 255.255.255.0 subnet mask (xx can be any number between 1 and 255 with the exception of 254). The computer and BSU must be members of the same IP subnet to communicate. When using the Multi-BSU software, the BSU and SU can be on different subnets (see Using the Multi-BSU Configuration Software in the Tsunami Multipoint Version 1.3 Reference Manual for information). Note: The BSUs default IP address is 192.168.20.253 with a subnet mask of 255.255.255.0. 2. Run the Base Station Configuration Software on the computer. To do this, from the Windows Start menu, select Programs Base Station Configuration Software. Note: The menu bar reads Base Station Configuration Software when the computer and BSU are connected to the same physical network. If the menu bar reads Configuration Software only, the two devices are not on the same physical network; confirm that they are connected to the same Ethernet network, check the Ethernet cables, and confirm that the BSU is powered on before continuing. Type dspconf and press the Enter key to view the BSUs current configuration settings. If you do not get a response to this command, confirm that the computer and BSU are on the same IP subnet. Chapter 2. Pre-Installation Tasks CPN 63179 26 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 3. Configure the BSUs IP settings:

Type setIP <IP address> and press Enter, where <IP address> is the new IP address you want to assign to the unit. For example, type setIP 192.168.20.20 to assign this IP address to the BSU. A. Close the Base Station Configuration Software and change the IP address of the computers Ethernet card so that it is in the same IP network as the BSUs new IP address; restart the computer if necessary. B. Open the Base Station Configuration Software and use the dspconf command to verify that the BSU and computer can communicate. C. Enter setSubnet <subnet mask> where <subnet mask> designates a subnet mask. Proxim does not recommend using a subnet mask wider than 255.255.248.0. D. If desired enter gateway <gateway address> where <gateway address> designates the IP address of the networks gateway. 4. To set the BSUs Terminal ID, enter setID <Terminal ID> where <Terminal ID> is a number between 1 and 2048). For example, setID 1 sets the units Terminal ID to 1. Note: Each BSU and Subscriber Unit (SU) in a cell must have a unique Terminal ID. 5. Use the setFrameSync command to set the proper GPS operating mode. When performing indoor tests, Frame Sync must be set to Independent mode (setFrameSync 1). A BSUs transmitter does not turn on if Frame Sync is set to Multi Sector while indoors. Frame Sync should be set to one of the Multi Sector modes only when multiple BSUs are installed in the field; these modes enable a BSUs GPS receiver so it can synchronize its frame timing with other BSUs. See Configuring the System for Multi-Sector Mode on page 29 for details about configuring and testing multi-sector operation. 6. If Range Security is enabled (set to 1), enter rangeSecurity 0 (zero) to disable this feature. You can enable it later once the SUs have been installed in the field. 7. Set the desired data rate using the modulation command (modulation <0 (60Mbps) | 1 (40 Mbps) |

2 (30 Mbps) | 3 (20 Mbps)>). This step is not applicable for BSUs that support 20 Mbps operation only. Set the desired frequency plan using the freqPlan command. (freqPlan < 4 (four channel | 5

(channel) | 6 (channel)>). Tsunami Multipoint offers several frequency plans and operating frequencies to provide a means for overcoming interference. If one part of the 5.8 GHz spectrum is occupied when you deploy the product, you can select a different frequency plan to bypass the interfering frequency. Chapter 2. Pre-Installation Tasks CPN 63179 27 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 8. Set the desired frequency plan using the frequency command. (frequency < a | b | c | d | e| f >;

with e being available for the 5 and 6 channel plans and f being available for the 6 channel plans only. 9. Set the BSUs desired transmit power level using the txPowerLevel command. Note: Typically the power level is set to 18 dBm in the field (maximum setting) and 6 dBm for indoor range testing (minimum level). 10. Set the desired transmit power auto-enable mode with the txPowerAutoEnable command

(txPowerAutoEnable < 0 (off) | 1 (on)>. When auto-enable is set to on the BSU will automatically start transmitting after any power cycle. 11. Set the desired routing mode with the routingMode command. (routingMode < 0 (IP routing | 1

(Bridging)>). Note: After you issue the routingMode command, you may need to clear the PCs arp table. (restarting the PC used to configure the BSU will do this). 12. Turn on the BSU using the txPower command (txPower <0 (off) | 1 (on)>). At this point the BSU is configured and ready to operate. Also, see Advanced Configuration Options and Command Reference in the Tsunami Multipoint Version 1.3 Reference Manual for information about the other commands used to configure the BSU (such as setting proxy, RIP, static IPs, and so on). Adding Subscribers to the BSU Database Subscriber units will not be able to enter the network until they are added to the BSU database. 1. Identify the Subscriber Units (SUs) you intend to use with this BSU and write down each devices MAC address (which is printed on the product label). 2. Add the first SU to the BSUs database by entering addSU <MAC address> <Terminal ID>. When typing the MAC address, separate each pair of digits with a colon or a blank space. The Terminal IDs range from 1 to 1023; assign a unique ID to each BSU and SU in a cell. For example, if the SUs MAC address is 00-04-44-12-34-56 and you want to assign Terminal ID 2 to this SU, enter addSU 00:04:44:12:34:56 2. Note: Add an SU to the BSUs database before installing or turning on the SU. Chapter 2. Pre-Installation Tasks CPN 63179 28 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 3. Configure the SUs IP settings:

Enter setSUIP <Terminal ID> <IP address> to set the SUs IP address. Proxim suggests that you configure each SU with a unique IP address in the same IP subnet as the BSU in Bridging mode and configure each SU with a specific subnet in IP routing mode. Enter setSUSubnet <Terminal ID> <subnet mask> to set the SUs subnet mask. 4. Repeat Steps 2 and 3 for each SU that you want to add to the Tsunami Multipoint system. 5. Enter dspSU to view the list of SUs that have been added to the BSUs database. 6. Install the SUs as described in Chapter 3. Deploying the Subscriber Unit on page 31. Configuring the System for Multi Sector Mode If you are installing the BSU in the same geographical location as other BSUs, i.e., in a location where one BSU may interfere with another, set the unit to Multi Sector mode; this enables the GPS receiver. GPS is used to ensure that all BSUs in the same geographical region transmit and receive at the same time. In additional, the ratio of downlink to uplink slots must be the same for all BSUs that may interfere with each other. Together, these eliminate the possibility of a BSU transmitting while a co-

located BSU is receiving. This synchronization is achieved using the timing signal supplied by the GPS receiver. The GPS receiver needs to see four satellites to obtain an accurate time. Once time has been initialized, the receiver can keep accurate time even if it sees only a single satellite. There are two multi-sectors modes; auto-restart and auto-resync. The difference between these modes has to do with how the BSU synchronizes its timing to gps after an outage. The reader is referred to the TMP reference manual for more details. To configure the BSU for Multi Sector Mode, use the setFrameSync command (setFrameSync <0 (Multi-sector with auto-restart | 1 (independent NOT multisector) | 2 (multi-sector with auto-resync). Multi-sector mode with auto-resync is the recommended mod). To turn off Multi Sector Mode, enter setFrameSync 1, indicating Independent (GPS is not used). Testing the GPS Receiver The GPS Receiver Test examines the quality of the GPS signal. This test is for use only in the field by customers who have installed multiple Base Station Units (BSUs) in the same location (with the Frame Sync parameter set to Multi Sector). This tool tests the GPS quality for BSUs that receive timing information from GPS satellites. Note: The BSU must have the GPS antenna connected to receive GPS signals. See Mounting the GPS Antenna. Chapter 2. Pre-Installation Tasks CPN 63179 29 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Follow these steps to run the test:

1. Open the Base Station Configuration Software. 2. Enter BSUlog 1 1. 3. The second output column is GPS sync, which will read 1 until the GPS can acquire the requisite number of satellites. When this number reads 0, GPS has acquired at least one satellite; when it reads 4, at least four satellites have been acquired and GPS is functional. 4. Enter BSUlog 0 to turn off BSU log. 5. Enter pp3d 1 to start the GPS test. The Base Station Configuration Software reports the following values (from left to right):

Column 1: Time error in half-chip; this value should be less than 80 Column 2: Frequency error Column 3: Synchronize filter; this value must equal 20 Column 4: Not applicable Column 5: GPS message; this value must be 4 Column 6: Visible sat; this value must be 4 Column 7: Time of week in 10 ms Columns 8 & 9: Not applicable Column 1 provides information concerning the level of frame synchronization and Column 6 provide information about the number of visible satellites. 6. Enter pp3d 0 (zero) to end the GPS test. Chapter 2. Pre-Installation Tasks CPN 63179 30 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Chapter 3.

Insert the two #10-32 screws in the sides of the mounting clamp housing/pole clamp assembly and loosely attach the two #10-32 nuts. Figure 19. Mounted SU 5. After you aim the SU (see Aiming the SU on page 35), tighten the two #10-32 screws and nuts to secure the SU in position. 6. Insert the O-ring into the SUs Power and Ethernet port. 7. Connect one end of the supplied Cat 5 cable to the SUs Power & Ethernet port and screw on the outer ring to secure the cable in place. Figure 20. SUs Power and Ethernet Connector and Grounding Screw Note: To ensure proper grounding, use the hole on the back of each SU and the provided grounding screws to attach a ground wire to each radio. Use wire grounding techniques in accordance with your local electrical codes. Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 33 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 8. Connect the other end of the Cat 5 cable to the SUs power supply. Be sure the Tsunami Multipoint Subscriber Unit connector is properly contacted or the unit may fail; you should hear a click when installing the cable connector to its chassis. The proper way to install is as follows:

A) Insert the O-ring into the SUs Power and Ethernet port. B) Loosen the rear nut on the end of connector cable. C) Pull the RJ-45 head out a few millimeters from the connector body. D) Push the RJ-45 head into the chassis connector and listen for a solid click. E) Push the water seal cap back and tighten the cap. F) Tighten the rear nut. Note: While not necessary, it is advisable to implement additional external weatherproofing, such as weatherproof tape and silicon at the inside base of the threaded part of the connector. 9. Connect one end of a Cat 5 cable to the SUs power supplys RJ-45 port and the other end to a switch or directly to the computer onto which you installed the Subscriber Utility. 10. Plug the SUs power supply into an electrical outlet. Installing the Subscriber Utility Software The subscriber utility is used in the antenna pointing process and must be installed to finish the SU installation. 1. Identify the computer on which you plan to run the Subscriber Utility. Note: See System Requirements for Base Station Configuration Software on page 51 for operating system and hardware requirements. 2. Insert the Tsunami MP CD (provided with the product) into the computers CD-ROM drive and open the CDs config software folder. Note:

If the computer has Microsoft IIS (Internet Information Services) running, disable or uninstall it before running the Subscriber Utility. 3. Double-click SUSETUP.HTM or use a Web browser to open the file. 4. Place a checkmark next to the Include VM in download option to install Java Virtual Machine (VM). Note: You need not add VM if your computer already has a version of VM installed. 5. Click the Start Installer for Windows button to begin the software installation. Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 34 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 6. Follow the on-screen instructions to install the software. 7. Click Done when the installation is finished to close the installer. Aiming the SU 1. Launch the Subscriber Utility. Figure 21. Settings Page in Subscriber Utility 2. Choose the desired frequency plan and operating frequency. The factory default is the 4 channel frequency plan and frequency auto (the SU looks through all frequencies). Selecting a specific frequency forces the SU to search for a BSU on that specific frequency only. When the Auto option is selected, the SU searches all frequency channels for a given plan until it finds the strongest signal. 3. Turn on the Audible Signal-Strength Indicator (if not already set to On). Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 35 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 4. Click Save Settings and Install Subscriber Unit to launch the aiming tool. Figure 22. Aiming Tool in Subscriber Utility 5. Slowly adjust the position of the SU until you have maximized the strength of the radio signal. The SU beeps after it has detected a signal from the BSU. The beeps increase in frequency as the strength of the signal received from the BSU increases. The Receive Signal Quality indicator within the Subscriber Utilitys Installation window reports the strength of the radio signal. 6. Click OK to close the aiming tool. 7. If you have left the Base Station Configuration Software running on the computer connected to the BSU, a notification is displayed once the SU has successfully joined the network (this is known as a net entry notification). Displaying Link Status Information The Status window displays the current information at the SU, as well as information about the link between the BSU and the local SU. The information is described following the figure. To display the Status window, launch the Subscriber Utility and then select the Status tab. The Status window is displayed, as shown in the following figure. Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 36 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Figure 23. Subscriber Utility Status Window Base Station ID Displays the Terminal ID assigned to the BSU with which the SU communicates. Operating Status When the link status between the BSU and local SU changes (for example, when you first power up the units, change their configuration, and so on) the following status messages appear in this field:

Searching for Outbound SU searches for an outbound signal (that is, a signal transmitted from the BSU) Inbound fine sync Indicates outbound signal detected and the SU is attempting to synchronize with the inbound signal Link established Indicates the link is established between the BSU and local SU. Note: The No connection message indicates that the software is unable to establish a link between the BSU and local SU. Also, the ODU Not Connected message indicates that the PC used to configure the SU is not communicating with it. See Troubleshooting in the Tsunami Multipoint Version 1.3 Reference Manual for possible causes and solutions to these problems. Burst Rate Shows the current Modulation setting. See Specify the Desired Modulation (Data Rate) on page 49 for information. Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 37 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Frequency Channel Shows the current channel plan/frequency setting (for example, 4C). See Change the Frequency Plan and Operating Frequency on page 50 for information. By default, the SU is set to automatically search for the correct frequency channel. Receive Signal Quality (dBm) Shows the quality of signal received by the local SU (in dBm). This value represents the estimated received signal level, plus an offset of 120 dB. A received signal quality level over 40 (which represents a signal level of -80 dBm) shows an acceptable signal quality. You can use this field to fine tune BSU/SU alignment. After you mount the units outdoors, check the Receive Signal Quality value as you make fine adjustments to the BSU/SU alignment until you obtain optimal signal quality. Transmitter Power Shows the SUs current transmitter power (-30 to +36). Ethernet Interface Shows the current Ethernet interface setting. If the Ethernet interface was set to auto-netotiate, this entry contains the results of the auto-negotiation. Network Mode Shows the current network mode: Bridging, VPN, or IP Routing. Confirming Network Activity Attempt to ping from a computer connected to:

An SU to the BS (BSU and SU must have different IP addresses to do this. If the BSU and SU are configured with the same IP address, the local unit responds to the ping (that is, if the BSU and SU have the same IP address and you ping the BSU from a host connected to the SU, the SU responds to the ping). The BSU to the SU. (BSU and SU must have different IP addresses to do this. If the BSU and SU are configured with the same IP address, the local unit responds to the ping (that is, if the BSU and SU have the same IP address and you ping the BSU from a host connected to the SU, the SU responds to the ping). If successful and possible, attempt to ping from a computer on the SU side of the network to a computer on the BSU side of the network. Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 38 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide If the ping tests are unsuccessful, attempt the following:

Check all IP and computer configurations (for example, if you attempt to ping the BSU from the SU configuration computer and the BSU and SUs are in separate networks you must have the configurations computers gateway set to the SU for the ping to work.) Adjust the networks IP settings, if necessary, to achieve IP connectivity. If the above fails refer to System Diagnostics to help debug possible link problems. Note: See Chapter 4. System Diagnostics and Operating Tips on page 40 for information about running system diagnostics to make sure the equipment is operating as expected . Chapter 3. Deploying the Subscriber Unit (SU) CPN 63179 39 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Chapter 4. System Diagnostics and Operating Tips This section describes several diagnostic tests you can perform once the Tsunami MP equipment is installed. These tests assist you in determining whether the equipment is functioning as expected. In addition, we include some miscellaneous useful information for deploying a Multipoint network. Radio Diagnostics Use the diagnostic tools described in this section to determine if your wireless link is stable. You can also use these tools to help fine-tune antenna positions to establish a good link. BSU and SU Logs You can display BSU and SU logs to help troubleshoot possible link reliability and interference issues. These tools have no impact on data traffic, and can be used in conjunction with configuration parameters

(such as IPC settings, modulation modes, and operating frequencies) and possible antenna relocation to obtain the best possible path. The goal is to maximize the Es/N0 ratio. Displaying the BSU Log Follow these steps to enable the BSU log:

1. Enter BSUlog (Terminal ID> <time> where <Terminal ID> is the Terminal ID of the SU to be monitored and <time> specifies the polling period (in seconds). Figure 24. BSU Log in the Base Station Configuration Software 2. When finished, disable the BSU log by entering BSUlog 0 (zero). Chapter 4. System Diagnostics and Operating Tips CPN 63179 40 Issue Date: 01/24/03

Tsunami Multipoint Version 1.3 Installation Guide Monitor the Es/No ratio (Es/No reports the energy per symbol-to-noise spectral density ratio (in dB)). Low Es/N0 or varying Es/N0 can indicate path or interference problems. The Es/No requirement varies based on the modulation mode:

20 Mbps: Es/No > 4 + IPC value 30 Mbps: Es/No > 5 + IPC value 40 Mbps: Es/No > 9 + IPC value 60 Mbps: Es/No > 12 + IPC value In addition, the BSU log provides the following information:

Int Relative interference of the power received at the BSU (a value of 0 (zero) nominally shows no interference) GPS sync

-1 indicates GPS sync is disabled; 4 indicates GPS sync is enabled. GPS synchronization is used when the system is in Multi Sector mode (multiple BSUs installed in the same location; see Configuring the System for Multi-Sector Mode on page 29 for more information). SU ID The Terminal ID of the monitored SU Time error Shows the uplink (or inbound) ranging error Rx cell error Shows the number of lost uplink cells Rx cells Shows the total number of uplink cells Time Shows the cumulative polling time (in seconds) Displaying the SU Logs You can display two different types of SU logs: SUlog1 and SUlog2. To display the SU logs, install the Base Station Configuration Software on the PC used to configure the SU (see Installing the Base Station Configuration Software for information) and then execute the commands described below. Follow these steps to enable an SU log:

1. Enter SUlog1 <time> or SUlog2 <time> where <time> specifies the polling period (in seconds).

(Specify SUlog1 to display SUlog1; specify SUlog2 to display SUlog2. See the information below for details about these two logs.) Chapter 4. System Diagnostics and Operating Tips CPN 63179 41 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide 2. When finished, disable the SU log by entering SUlog1 0 (zero) or SUlog2 0 (zero) (depending upon which log you displayed). SUlog1 provides the following information:

SU ID The Terminal ID of the monitored SU. RSL Shows the shows the RSL (receiver signal level) at the output of the antenna (in dBm). TX Power Shows the SUs TX power at the input to the antenna (in dBm). VCO Shows the relative frequency offset of the VCO (voltage control oscillator) (in Hz). Time error Shows the synchronization error (in 1/512 symbol), generally magnitude (should be less than 8). OB pkt error Shows the number of out-of-sequence outbound packets. Range Shows the SUs distance from the BSU (in meters). Figure 25. Log 1 SUlog2 provides the following information:

SU ID The Terminal ID of the monitored SU. Missed VARSYS Shows the number of missing downlink control packets. aloha retx Shows the number of packets retransmitted due to collisions (collisions are a normal event on contingent channels. An excessive number may indicate a problem). Chapter 4. System Diagnostics and Operating Tips CPN 63179 42 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide IB pkts Shows the number of inbound packets transmitted. OB pkts Shows the number of outbound packets received. OB PE Shows the number of outbound packet errors. OB PER Shows the error rate for outbound packets received. Time Shows the cumulative polling time (in seconds). Figure 26. SU Log 2 Uplink BER Test The Uplink BER Test determines the BER (bit error rate) of the uplink signal. This is an out-of-service diagnostic tool and the data connection is terminated for the length of the test. Use this tool to determine whether the link is stable (that is, there are no bit errors). You can also monitor these test results to fine tune antenna alignment to get the strongest link possible. Note: Do not run this test if users are sending data across the radio link. Follow these steps to run the Uplink BER Test:

1. Open the Base Station Configuration Software. 2. Enter uplber <Terminal ID> to start the test for a particular SU. <Terminal ID> is the Terminal ID of the SU of interest. 3. Enter berlog 1 to view the test results. Chapter 4. System Diagnostics and Operating Tips CPN 63179 43 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Figure 27. BER Log in Base Station Configuration Software 4. Monitor the BER test results. The Es/No is reported in column 1 and BER is reported in column 2. The BER should initially read 0E-6 or oE-7 but then change to 0E-8 and finally to 0E-9 while the test is running. This corresponds to 0 (zero) bit errors. The numbers in parentheses indicates the number of errors over the total. 1E-6 indicates a bit error rate of 1 bit error received for every million bits sent. 5. When finished, disable the Uplink BER Test by first entering berlog 0 (zero) and then entering uplber 0 (zero). Note: The data connection does not resume until the uplber 0 (zero) command has been issued. Network Configuration Tips Keep the following points in mind when configuring your PMP network. Tips for Testing PMP Network Under IP Routing Mode Make sure to configure the BSU such that:

If the BSU is connected to a router, make sure the router port to which the BSU is connected is defined as the BSUs default gateway. Also, make sure the BSU is specified as the router ports default gateway. The IP addresses of the BSU and the router port reside in the same subnet (this is required). Chapter 4. System Diagnostics and Operating Tips CPN 63179 44 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Make sure that an SU and its directly connected devices are in the same subnet. The subnet address of a device can be obtained by performing a logical AND of the devices IP address with its subnet mask. A subnet mask of 255.255.255.0 implies that there are 255 IP addresses within the same subnet. If the IP address of a PC connected to a SU is not dynamically assigned:

Make sure the PCs IP address appears in the SUs static IP list (see addSUIP Command in the Tsunami Multipoint Version 1.3 Reference Manual). Otherwise, if the SU is running in Restricted mode, the PC cannot access the wireless network. Configure the PC to point to the SU as its default gateway. In the latest firmware release, the proxy setting is turned on automatically; do not change this setting. Tips for Testing VLAN Switching Before changing the BSU Configuration to VLAN switching, make sure that the BSU and the BSU console are connected to a VLAN switch. Otherwise, if you turn on VLAN tagging, you cannot talk to the BSU because the PC hosting the BSU Console cannot send or receive VLAN frames. Tips for Anyone Operating the PMP Network When changing back and forth between Bridging mode and IP Routing mode (see routingMode Command in the Tsunami Multipoint Version 1.3 Reference Manual), always remember to manually clear the ARP table of your PC. Do not turn off the power of the Base Station Unit at-will, because the Base Station Unit might be saving internal variables or configuration parameters to the flash memory at that moment. Always wait for a minute after entering an operator command before shutting down the BSU. Always follow the simple proxy rule and fundamental principles concerning subnets and default gateways in planning and analyzing the PMP network. A good understanding of basic IP networking is required, regardless of whether you operate the PMP network in IP Routing or Bridging mode. If you cannot get the network to work, there is most likely a setup error. Check the network configuration using the tips above and try again. Protecting the System Tsunami Multipoint provides ways to prevent unauthorized users from communicating with the BSU and SUs. You can password-protect the system to prevent unauthorized access and use the Range Security option to prevent unauthorized SUs from communicating with a BSU. Chapter 4. System Diagnostics and Operating Tips CPN 63179 45 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Password Protection Tsunami Multipoint provides two levels of password protection:

user level lets the user display the systems current status only. admin level lets the user display the systems status and change its configuration. The default password is null. Password protection for either password level (user or admin) can be turned on and off. By default, password protection is turned off. Passwords can be from 1 to 16 characters; any combination of alphanumeric characters is allowed, except for these special characters: " , . ^ { } | \ / ; : ] [ ( ) If you forget your password, contact Proxims Customer Service department to obtain a new one. See Appendix F. Technical Support and Training on page 76 for Proxims contact information. Specifying a User-Level Password To define the user-level password, from the BSU console enter:

setpw user<oldpw><newpw><newpw>

where:

<oldpw> = the old password (the default password is null)

<newpw> = the new password After defining the new user-level password, enter logout. Log in with the new password (see Logging In on page 47 for information). Specifying an Admin-Level Password To define the admin-level password, from the BSU console, enter:

setpw admin<oldpw><newpw><newpw>

where:

<oldpw> = the old password (the default password is null)

<newpw> = the new password After defining the new admin-level password, enter logout. Log in with the new password. Note:

If you specify either level of password without specifying a password for the other level, when you log out or restart the BSU, the system comes up in password-protected mode. Log in and enter the password you specified. For example, if you specify admin for the admin-level password and then log out or restart the BSU, enter login admin to access the system. This allows access to the admin-level. Chapter 4. System Diagnostics and Operating Tips CPN 63179 46 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Turning Off Password Protection To turn off password protection, from the BSU console, enter setpw<level><oldpw><null><null>

<level> = either admin or user, depending upon which level of password protection you want to remove. For example, if the current admin password is superuser, to remove the admin password, enter setpw admin superuser null null.

<oldpw> = the old password. If you turn off both display-level and user-level password protection, restart the BSU to refresh its memory. Figure 28. Password Definition/Usage Diagram Logging In If password protection is turned on, you must log in to the system to either display system status

(user-level privileges) or change the systems configuration (admin-level privileges). To log in, enter login <password> where <password> is either the user-level or admin-level password. Chapter 4. System Diagnostics and Operating Tips CPN 63179 47 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Activating Range Security The Range Security option helps prevent unauthorized SUs from communicating with a BSU. When the Range Security option is on, if an SU attempts to enter the network, the BSU checks the range value reported by the SU. This works as follows:

The first time the SU tries to enter the network, the SUs range is stored in the BSUs flash memory for future reference. Then, if the SU enters the network again (when Range Security is on) and its reported range does not match the range that was previously stored in the BSUs flash memory, the SU is denied network entry and an alarm is sent to the BSU console. To activate the Range Security option, from the BSU console, enter rangeSecurity 1. Chapter 4. System Diagnostics and Operating Tips CPN 63179 48 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Appendix A. Initial Settings Specify the Desired Modulation (Data Rate) To configure the BSU to use the modulation setting required by your application (20, 30, 40, or 60 Mbps), from the BSU console, enter modulation <mode number>, where:

<mode number> =

0 (zero) = QAM16 (60 Mbps) 1 = QAM8 (40 Mbps) 2 = QPSK3Q (30 Mbps) 3 = QPSK1H (20 Mbps) The BSU automatically restarts and then comes up with the new modulation setting. The Subscriber Units adopt the new modulation setting (the new modulation setting appears in the Burst Rate field on the Status page of the Subscriber Utility). Note: This step is not applicable if the BSU operates at 20 Mbps only. Specify the BSUs Gateway Address In general, you should specify the IP address of the router connected to the BSU as its gateway address. If your network does not have a router installed, specify the IP address of the BSU console. To specify the BSUs gateway address, from the BSU console, enter gateway <gateway address> where <gateway address> is the IP address of the router attached to the BSU or the BSU console. Select the Routing Mode Set the BSU to operate in IP Routing mode or Bridging mode. A BSU is set to IP Routing mode by default. See the routingMode command in the Tsunami Multipoint Version 1.3 Reference Manual for more information about these modes. After you change the routing mode, the BSU restarts and forces all the SUs in its sector to restart. The BSU and SUs then come up with the new routing mode. To select Bridging as the routing mode, from the BSU console, enter routingMode 1. To select IP Routing as the routing mode, enter routingMode 0 (zero). Appendix A. Initial Configuration Settings CPN 63179 49 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Change the Frequency Plan and Operating Frequency Tsunami Multipoint offers several frequency plans and operating frequencies to provide a means for overcoming interference. If one part of the 5.8 GHz spectrum is occupied when you deploy the product, you can select a different frequency plan to bypass the interfering frequency. To select a frequency plan and operating frequency, specify a frequency plan (4, 5, or 6), then one of the available frequencies (one of four frequencies for plan 4, one of five frequencies for plan 5, one of six frequencies for plan 6). Plan 4 is the default frequency plan. Operating frequencies in the 5 and 6 plans overlap. See Frequency Plans on page 57 for details about the available frequency plans and operating frequencies. To select a frequency plan, from the BSU console, enter freqPlan<frequency plan> where <frequency plan> is 4, 5, or 6. To select an operating frequency, from the BSU console, enter frequency<frequency ID> where

<frequency ID> is:

For plan 4: A, B, C, or D For plan 5: A, B, C, D, or E For plan 6: A, B, C, D, E, or F For example, to change to the 5e plan, enter freqPlan 5; then enter frequency e. Appendix A.

Firmware Downloads Firmware can be downloaded to the BSU using the local console. Firmware can be downloaded to the SU either over-the-air or from a local console (by attaching a PC with the Base Station Configuration Software to the SU). Proxim recommends you download new code as follows:

1. Download the new code to the SUs and verify that they re-enter the network. 2. Next, download new code to the BSU. Appendix B. Installing the Software and Upgrading Firmware CPN 63179 54 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Remote Over-the-Air Download to SUs You can upgrade your SUs to Version 1.3 from the Base Station Configuration Software Console of the BSU. Normally, all SUs in the network are upgraded at the same time. However, if one or more SUs fail to receive the download code correctly, the upgrade is aborted and a second attempt must be made. SUs that have been upgraded successfully ignore reprogramming of the same codes. To download remotely to SUs:

1. From the BSU 1.4 or 1.5 Console, confirm that SUs have established a link with the BSU by issuing a dspActiveSU command. Make note of the SUs in the network. 2. Select the Download menu. 3. Select Remote Firmware; a Download File Selection window is displayed. 4. From the Look In search field, select the binary file to be downloaded (PMP_SU_release1-3.mot) from the appropriate directory. The BSU Console automatically processes the selected binary codes and, once finished, displays an output of Elapsed [time] in seconds. 5. Let the SUs re-enter the network. It usually takes no more than five minutes for the SUs to enter the network from the start of the download. The following messages are displayed at the BSU Console for each SU as it enters the network:

118 Received NetEntry Request from Eth<SUs Ethernet address>

119 NetEntry completed: Assigned terminal ID <ID#>, IP<SUs IP address>, and VLAN ID

<SU VLAN ID#> in VLAN mode. 6. Issue dspActiveSU to verify that the SUs have entered the network successfully. If an SU fails to enter the network, use the local download procedure in the following section. If the SU was correctly upgraded, the display reads ver 20021300. If the SU failed to upgrade and the link was restored, the display most likely reads ver 200212B0. 7. If any SU that re-entered the network failed to upgrade to Version 1.3, repeat steps 2 through 6, or upgrade the failing SUs using the Local Download to SUs method. Local Download to SUs You can use this method to upgrade SUs that have not been deployed or have failed to successfully download using the remote over-the-air procedure. Using this procedure, individual SUs are upgraded through their Ethernet/Power cable. This procedure requires the Tsunami Multipoint Base Station Configuration Software application be loaded on the PC attached to the SU (SU 1.,4 or 1.5 Console). The window label appears as Tsunami Multipoint Subscriber Configuration Software. Appendix B. Installing the Software and Upgrading Firmware CPN 63179 55 Issue Date: 01/24/03

Tsunami Multipoint Version 1.3 Installation Guide To download locally to an SU:

1. From the SU 1.4 or 1.5 Console, select the Download menu. 2. Select Local Firmware. 3. From the Look In search field, choose the binary file to be downloaded (PMP_SU_release1-3.mot) from the appropriate directory and click Select. The download requires about 2 minutes. Once the download is complete, the banner indicating Version 1.3 is displayed. If the download does not complete successfully, as indicated by a checksum mismatch or a failure to reboot, cycle power to the SU and repeat, starting at step 1. Local Download to the BSU Use this download method to upgrade BSUs after the SUs have been upgraded to Version 1.3. The BSU is upgraded through its Ethernet/Power cable using the BSU 1.4 or 1.5 Console. To locally download to the BSU:

1. From the BSU 1.4 or 1.5 Console, select the Download menu. 2. Select Local Firmware. 3. From the Look In search field, choose the binary file to be downloaded (PMP_BSU_release1-3.mot) from the appropriate directory and click Select. 4. Once the upgrade is successful, if there were SUs connected to the BSU, they will re-acquire net entry. For each SU connection, two messages are displayed:

120 Received NetEntry Request from Eth<SUs Ethernet address>

121 NetEntry completed: Assigned terminal ID<ID#>, VLAN ID 1, IP<SUs IP address>

It normally takes less than a minute and a half for the SUs to re-acquire NetEntry with the BSU from the time the local download started. 5. If there were no SUs connected to the BSU, after the upgrade succeeds, the version banner is displayed with version 20021300, following by three messages:

114 Completed flash sector verification 103 DB check completed 107 Save NV configuration Parameters Once the SUs are re-connected to the BSU, expect the same behavior as specified in step 4.

The connector is a reverse sex plug with male connector pins. The plug provided is not weather tight and is meant for indoor use only. The connector uses a shield to cover the pin end of the wires and has a strain relief clamp with two self-tapping screws to clamp the cable sheath to the connector. Figure 44. 8-Pin AMP Connector To install the AMP CPC connector on the BSU Power and Ethernet cable:

1. Install the shield on the cable before removing the cable jacket. Slide the shield onto the cable so that the threaded, large-diameter end faces the end of the cable. 2. Crimp the contacts to the wires according to the documentation included with the crimp tooling. Pins are size 20 DM and the wire strip length is 0.100. 3. Insert the contacts into the housing one at a time by gripping the insulation of the wire directly behind the contact and aligning the contact with the back of the desired contact cavity. 4. Insert each contact straight into the cavity until it bottoms, then pull back lightly on the wire to be sure the contact is locked in place. 5. Thread the shield onto the connector and tighten the shield finger-tight. 6. Screw in the strain relief over the end of the cable using the two supplied Phillips head screws. Appendix D.

Tsunami Multipoint Base Station Unit 40400-25/-65 Tsunami Multipoint Subscriber Unit 40100-251/-252/-651/-652 Introduction What is Lightning Protection?

All outdoor electronic equipment is susceptible to lightning damage. Proper grounding to national and local codes is instrumental in providing human safety. Lightning Protection is used when a customer wants to maximize the reliability of the electronic system by diverting the excess energy that can be induced on any transmission lines (data, power) through a series of surge protection devices. The energy is dissipated through heat and also diverted to ground. What Lightning Protection is Built Into the Tsunami Equipment?

All Tsunami Multipoint and QuickBridge equipment have built-in lightning protection on both the power supply lines and the Ethernet lines. There are TVS diodes that provide protection to IEC 61000-4-5. Proxim Corporation uses well-design practices in incorporating these devices in the Tsunami Multipoint and QuickBridge products. Why is Additional Protection Recommended?

Lightning, even with the built-in protection, can still damage outdoor Tsunami equipment. This can occur for any number of reasons, such as an improperly grounded installation or if the amount of transient energy from nearby lightning exceeds what the devices can handle. If a Tsunami unit fails due to damage from lightning, the link is out-of-service until the unit is replaced or repaired. An external, revertive protection device can provide a higher level of protection, and greater probability of surviving lightning transients without damage to the Tsunami equipment. If damage does occur, most likely it is to the lightning protection devices and not the Tsunami equipment. Remember, even with external lightning protection, damage can still occur to the Tsunami outdoor unit. Appendix E. Lightning Protection Recommendations CPN 63179 70 Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Recommendation Proxim recommends the following for its Tsunami Multipoint products:

This product can be used for all CAT5 cable lengths up to 100 meters from the outdoor Tsunami unit to the indoor power adapter. The Polyphaser Data Protector uses Cascade Technology. This is a multi-stage technology that is superior to single stage because of high surge current capacity and fast response time. The unit is designed to fit in-line onto the outdoor Cat 5 cable, using two weatherized plug openings for the cable to enter and exit. The existing cable is cut, dressed, and reconnected onto two sets of 8 screw terminals inside the Data Protector. List Price: $209/ea. Delivery: Available from authorized Proxim reseller or installer off-the-shelf. Appendix E. Lightning Protection Recommendations CPN 63179 71 C-

Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Transtector Systems Surge Supressor This outdoor-use, molded plastic, weather-tight enclosure is a surge suppressor designed to protect the Tsunami Multipoint SU and the QuickBridge unit from lightning damage. This product can be used for CAT5 cable lengths up to 50 meters from the outdoor Tsunami unit to indoor power adapter. The 1101-TSU uses silicon avalanche suppression diodes (SASD) to provide lower voltage protection level

(VPL). This technology provides a superior protection level over traditional gas tube type devices. The unit is designed to fit onto a CAT5 cable in a pass-through configuration. The input and output connections can be made at two sets of 8-screw terminals, or two 8-pin DIN style connectors. This arrangement allows the installation of the connectorized Cat 5 cable directly into the Surge Suppressor, or with a cut cable. List Price: $99/ea. Delivery: Available from authorized Proxim reseller or installer off-the-shelf. Physical Considerations How are the Lightning Protection Units Connected to the CAT5 Cable?

The lightning protection units recommended are designed to be installed in-line onto the Cat 5 cable that connectors the outdoor (RF) Tsunami unit (Base Station, Subscriber Unit, QuickBridge) and the indoor power adapter. The lightning protection device has a Surge (cable-facing) side, and an Equipment (equipment-facing) side. The Equipment side faces the outdoor Tsunami unit or the indoor power adapter. The Surge side faces the long length of cable; when installing two lightning protection units, each units Surge side face one another. See Pin-out information for each unit in Lightning Protection Specifications on page 73 for connecting the cable to the protection device. Appendix E. Lightning Protection Recommendations CPN 63179 72 C-

Issue Date: 01/24/03 Tsunami Multipoint Version 1.3 Installation Guide Where Should the Protection Units be Located?

At least one unit should be installed near every outdoor Tsunami unit. General guidelines are:

Locate protection unit as close to the outdoor Tsunami unit as possible, where the lightning protection unit can be securely mounted to a flat surface and grounded properly. Ideally, this should be no further than five feet away from the outdoor unit. Locate one unit at the roof penetration point, outside, so that the cable immediately enters the building after the protection unit. This unit is optional if the distance from the first unit to the roof penetration point is relatively short (under 15 feet). Installing two units provides the maximum protection against lightning damage to the outdoor Tsunami unit and the indoor power adapter, especially if the CAT5 cable length is greater than 15 meters.
