Tsunami Multipoint Version 2.0 Installation Manual
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?
º
º
▪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 user’s 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.

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 4.45 to obtain
newtons, or by 0.45 to obtain kilograms of force. 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.

Tsunami Multipoint Version 2.0 Installation Manual
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-RJ-45 Local Area Network Protector (see Erico’s 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 63 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 an A.I.R. (Active Interference Rejection) 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.
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.

Tsunami Multipoint Version 2.0 Installation Manual
ANTENNAS
Antennas frequently play a key role in reducing the potential for interference. They come in a variety of
configurations that have different gain and direction 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.

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.
Chapter 1. Site Planning 12

Tsunami Multipoint Version 2.0 Installation Manual
Antenna Polarization
The Tsunami Multipoint system uses left-hand circular polarization (LHCP). 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/ .
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
Alink 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.
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 51 for product technical specifications.
Chapter 1. Site Planning 13
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

Tsunami Multipoint Version 2.0 Installation Manual
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 45 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
configurable (within limits; see “setFirstInboundSlot” in the Tsunami Multipoint Reference Manual for details)
Tx Power and Antenna Specifications
See “Tx Power,” “txPowerLevel,” and “Antennas” in the Tsunami Multipoint 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 Reference Manual for more information.

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 product’s 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 CAT5 cross-over or straight-through cable (see step 5) and a BSU power adapter (the BSU’s power
supply is ordered and shipped separately; the power supply’s CPN number is 58526).

MOUNTING THE BASE STATION UNIT
Before mounting the BSU, note the serial number of the unit along with the name of the site at which the unit was
installed. Keep this information in a safe place. The serial number is required to obtain support from Proxim.
You can mount the outdoor component of your Tsunami Multipoint Base Station Unit directly to a pole with an
outside diameter of 1-½ to 4-½ inches.
Mounting the BSU is essentially a two-step process:
1. Assemble the BSU’s mounting components on the ground (ground work).
2. Mount the BSU to a pole using the mounting components.

Required Tools: 9/16” (14-23 mm) wrench
6” (155 mm) crescent wrench
Note: Torque all #3/8 bolts and nuts 250 ±10 in-lbs.
BSU Mounting: Ground Work
To assemble the BSU’s mounting components:
1. Place the BSU face (transmitter side) down on a flat surface.
2. Attach the two (U-shaped) galvanized mounting brackets to the back of the BSU using the four stainless steel
3/8-16, hex head screws and four #3/8 split lock washers (shown in the following figure).

3. Insert two ½-13x7 ½ screws through one of the clamp brackets (M-shaped) and secure the bolts using two ½-
13 hex nuts. Repeat this step for the other set of ½-13x7 ½ screws, clamp bracket, and ½-13 hex nuts (see the
following figures).
4. Connect the downtilt bracket to the notched bracket using two 3/8-16x1 1/4 hex head screws, # 3/8 split lock
washers, # 3/8(star) lock washers, and 3/8-16 hex nuts (see the following figures).

5. Attach the downtilt/notched bracket assembly to the U-shaped mounting bracket near the middle of the BSU
using two sets of 3/8-16x1 ¼ hex head screws, # 3/8split lock washers, and 3/8-16 nuts.
Note: This mounting method lets you point the BSU down when mounted on a pole; to point the BSU up,
attach the downtilt/notched bracket assembly to the U-shaped mounting bracket near the bottom of the
BSU.

6. Attach one of the ½-13x7 ½ screws/clamp bracket assemblies to the U-shaped mounting bracket near the end
of the BSU using two sets of 3/8-16x1 ¼ hex head screws, # 3/8split lock washers, and 3/8-16 hex nuts (see the
following figure). (In this configuration, the BSU points down when mounted on a pole.)
7. Attach the other ½-13x7 ½ screws/clamp bracket assembly to the downtilt bracket using two sets of 3/8-16x1 ¼
hex head screws, # 3/8split lock washers, and 3/8-16 hex nuts (shown in the following figure).

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 # ½ split lock washers
and four ½-13 hex nuts (shown in the following photo).

2. To adjust the up/down tilt (-10º to +5º), 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 CAT5 cable to the BSU’s Power and Ethernet port as described in the following notes.
Then screw on the outer ring to secure the cable in place.

Tsunami Multipoint Version 2.0 Installation Manual
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 CAT5 cable to the
BSU’s 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 connector’s 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.
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. [phone]) to ensure a better water seal.
