2. System Overview
A system is made up of one to six Base Stations that make up a Hub (or cell) with
each Base Station communicating with their associated SUs (Subscriber Units).
Together, they provide a wide coverage, high-capacity system that transfers IP traffic
between the Hub and its multiple SUs. Each Hub has the ability to communicate in all
directions using up to six sectors of 60 degrees each. Each of the Hub’s six sectors has
the capability of communicating 20, 30, 40 or 60 Mbps in total bandwidth allowing a
maximum of 360 Mbps per Hub.

Site Planning Considerations
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 multipath signals, reducing the effect of obstructions in the path, it is
important that the characteristics of the path be carefully examined. With this
knowledge, components and network requirements can be correctly planned for your
specific application.
This chapter 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 a clear line of sight cannot be achieved, you must plan accordingly.
Other general site considerations include:
a. Will a tower have to be constructed? Are permits required?
b. 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?
c. Availability of grounding-Good grounding is important in all areas of the
world, but in areas prone to lightning, it is especially critical.
d. Availability of power-Are redundant power systems available if the area is
prone to outages?
The planning of a wireless link involves collecting information and making decisions.
The following sections will help you determine which information is critical to the site
and will be an aid in the decision-making process.
TSUNAMI MULTIPOINT
2-3
Weather
It is important to research any unusual weather conditions that are 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, it is recommended that these conditions be taken 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 or 8 GHz. When
microwave frequencies are at 10 or 12 GHz or above, 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 can adversely affect the radio link when such as temperature inversion,
or very still air accompanied by stratification. Temperature inversion can negate
clearances, and 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, it is
recommended that shorter paths and adequate clearances are used.
WIND
Any system components mounted outdoors will be subject to the effect of wind. It is
important to 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, depending
on the area presented to the wind. This is known as wind loading.
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.
LIGHTNING
The potential for lightning damage to radio equipment should always be considered
when planning a wireless link. A variety of lightning protection and grounding devices
are available for use on buildings, towers, antennas, cables, and equipment, whether
located inside or outside the site, that could be damaged by a lightning strike.
Lightning protection requirements are based on the exposure at the site, the cost of
link down-time, and local building and electrical codes. If the link is critical, and the
TSUNAMI MULTIPOINT
2-4
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.
Recommended is lightning protection for cables leading to the wireless ODU to/from
the power brick. The lightning protection should be placed at points close to where
the cable passes through the bulkhead into the building, as well as near the ODU.
CAT5 CABLE
When the entire control cable, from the building entrance to the ODU, is encased in
steel conduit, no surge arrestors are required. Otherwise, each control cable requires
one surge arrestor within two feet of the building entrance.
Note For installations with several radios, it may be more convenient to use a Type-
66 punch block with surge arrestors. A Type-66 punch block can accommodate up to
25 conductor pairs.
INTERFERENCE
An important part of planning your broadband fixed wireless system is the avoidance
of interference. Interference can be caused by effects within the system or outside the
system. Good planning for frequencies and antennas can overcome most interference
challenges.
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 if any strong signals are present at the site and, if they are, to determine how
close they are to the desired frequency. The further away from your proposed
frequency, the less likely they are to cause a problem. Antenna placement and
polarization, as well as the use of the built-in high-gain, low-sidelobe antennas, is the
most effective method of reducing this type of interference.
TSUNAMI MULTIPOINT
2-5
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 directionality. 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
Antennas: the narrower, the better
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 can not be detached.
Base Stations Subscriber Units
Type: Flat-panel antenna Flat-panel antenna
Beamwidth: 60-degree 10-degree
Elevation: 6-degree 10-degree
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 to reduce
interference between your own adjacent installations. Antennas are tuned to operate
on a specific group of frequencies. Tsunami Multipoint offers a variety of channel
plans that provide a flexible tool for overcoming present and future interference. Four
non-overlapping 20 MHz channels (six total directional channels) can be used to avoid
existing traffic in the 5.8 GHz frequency band. If one part of the 5.8 GHz spectrum is
occupied when Tsunami Multipoint is initially deployed, another frequency channel
can be selected to bypass the interfering signal. If interference arises after deployment,
another frequency channel plan can be selected to “steer around” the impacted
channel. Beamwidth and gain have been optimized in this equipment.
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 multipath degradation of the signal
quality.
TSUNAMI MULTIPOINT
2-6
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
wwwfcc.gov/wtb/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 will attenuate the signal.
CALCULATING A LINK BUDGET
A link budget is a rough calculation of all known elements of the link to determine if
the signal will have the proper strength when it reaches the other end of the link. To
make this calculation, the following information should be available:
The minimum antenna height at each end of the link for paths longer than seven miles
(for smooth terrain without obstructions) is the height of the First Fresnel Zone plus
the additional height required to clear the earth bulge.
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 that you can expect, on
average, over a period of one year. Table 2-2 shows how percentage availability relates
to outage time per year.
Note: use the path planning tools located on the WMUX web site: www.wmux.com
Note You can lower the bit error rate (BER), resulting in greater reliability, by
reducing the data throughput or reducing the distance.
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
TSUNAMI MULTIPOINT
2-7
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.

3. Quick Set-up Procedure
Please read this section completely before attempting to install any software, test or
operate this system.
Permanent damage to the equipment can result if directions are not followed
exactly as provided.
This system is very sensitive to power supply operation and, if not powered up
in the proper order, permanent damage may occur. Please read the power up
sequence before applying power. Also, provide only the power specified in this
document (voltage and frequency).
Important Configuration Notes
These Subscriber Unit (SU) devices do not require any user interface. After
configuring the Hub unit (called Base Station (BS) in this document elsewhere), the
CPE devices will automatically negotiate with the Hub if sufficient signal strength is
received in both directions to establish communications.
The Ethernet Console program is not ultimately intended to be a user’s interface.
However, this program does provide configuration controls for this particular system.
The syntax of the data entry must be followed exactly as shown. When a string of
characters is shown in this document with quotation marks around it (such as “ip”),
do not type the quotation marks. When the letter “x” is shown within the quotation
marks, this represents a number that the operator will select based on other factors.
When the word (enter) is shown, this indicates pressing of the Enter (or Return) key
on your keyboard. Wherever there are spaces shown in the syntax of a command,
include these spaces. Commands are case sensitive.

§ To verify the frequency channel, type “frequency” (enter).
§ At any time, if you wish to return a unit to the factory default settings, you may type
“restart” (return) or cycle power (using the toggle switch on the power supply). It is
advised to use the restart command.

Subscriber Unit Configuration
The CPE units require the same software and are connected and controlled in an
identical fashion as the BS. Configure the BSU unit and your computer first to
become familiar with these connections and controls and to be ready to connect to the
CPE.
§ CONNECT ALL CABLES BEFORE PLUGGING INTO AC POWER
§ DISCONNECT AC POWER FIRST BEFORE REMOVING THE CABLE BETWEEN
THE POWER SUPPLY AND CPE
ONLY THEN APPLY 115VAC 60 Hz POWER
When your PC is connected to a CPE unit, the Ethernet Console will display “SU
Console” (instead of BSU Console) in the upper right corner of the screen.
Use the IP, gateway and subnet mask commands to change or verify these settings for
each CPE unit. No other commands should be needed. The CPE will automatically
detect proper operating frequency and bandwidth settings.
It can be helpful to configure the CPE equipment before it establishes a link with the
BS. When RF communication is initiated, the units will start negotiating and
registering IP addresses, setting frequency channels and other settings. The terminal
number of the CPE is labeled on the bottom of the CPE, and this number (along with
IP address and Ethernet address) will appear on the BSU console screen when the
CPE is negotiating with the BSU for initialization.
When a link is established, both ends of the system will display different
communications on the Console window. The signal strength can be seen on the SU
Console, and this can be used as a rough antenna alignment tool. The command to
view signal strength is “rsl” (return). To align antennas, align by sight, type “rsl”
(return) in the SU console, read the RSL, make fine adjustments to the antenna
alignment, and type “rsl” (return) again, repeating until signal is peaked. The number
returned by the rsl command is in dBm, therefore, the less negative the number, the
stronger the signal (such as –40 is higher than –50).

Mechanical Considerations – Mounting Units
The CPE units are designed to directly mount to 1-1/2 inch to 1-3/4 inch pole
diameters (outer diameter), or mount to pole diameter of 2 inches or to a wall or other
flat surface using optional mounting brackets.
For mounting directly to a 1-1/2 inch or 1-3/4 inch pipe, first attach the mounting
bracket to the pole using the U-bolt retainer. Then attach the SU to the mounting
bracket, and lock into position by tightening the 10-32 screws. See photos below for
detail. Connect the weatherproof RJ45 connector.
For mounting to a flat surface, attach mounting bracket to the CPE using bolts
supplied, and then mount to flat surface using your own hardware.

The BSU is designed to mount to a 2 inch to 2-3/4 inch pipe using the bracket and
hardware supplied. See photos below for detail.
