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 Mbps in total bandwidth allowing a maximum of
180 Mbps per Hub.
Figure 2-1: Each HUB is made up of one to six Base Stations and multiple
remotes(SUs)
Uplink and Downlink, each SU communicates with a BSU in a coordinated manner so that
all other remotes within the BSU’s jurisdiction have an equal amount of time to coordinate
their data needs in both the uplink and downlink sessions. All SUs are very quickly handled on
a case by case basis giving the user, at the SU, the impression that they are in constant
communication with its Hub’s or BSU’s Sector.

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. Distance between the indoor portion of the system and the user’s network.
e. The SU may potentially be served by different Base Stations. Can the best
BSU access and available sighting location be determined prior to installation.
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.
2-2
T S U N A M I
M U L T I P O I N T
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 GHz. When
microwave frequencies are at 10-12 GHz range 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
site is in an active lightning area, attention to thorough lightning protection and
grounding is critical.
2-3
T S U N A M I
M U L T I P O I N T
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 additional lightning protection in those regions that have extreme
lightning occurrences for cables leading to the wireless OutDoor Unit (ODU)
to/from the indoor power brick. 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 ODU. Use the earthing screw at the ODU and use proper grounding.
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 Type66 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.

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.

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.

T S U N A M I
M U L T I P O I N T
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.
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 considered.
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. Freespace 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-ISM
The FCC has identified the frequencies from 5.725 to 5.825 GHz as an Industrial,
Scientific, Medical (ISM) band. 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.

3 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.
Important Configuration Notes
The Subscriber Unit (SU) does not normally require any configuration prior to
operation. The SU will automatically negotiate with the Base Station Unit when
sufficient signal strength is received in both directions to establish communications.
For custom configurations, the Subscriber Utility software, supplied on the CD,
provides the capability to configure and control the SU. 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.
Unpacking the System
Pay close attention to how units are packed before unpacking.
SEE PHOTO BELOW AND NEXT PAGE FOR CLARIFICATION
Unpacking should be in the following steps:
a. Remove power supply units
b. Remove small metal brackets

Mechanical Considerations – Mounting Units
The outdoor component of the Subscriber Unit (SU) is designed to directly mount a
pole. Using optional mounting brackets, the SU can be mounted to a wall or other flat
surface. Using the supplied U-bolts, the SU will mount to a 1-1/4 inch to 2 inch pole
diameter (outside diameter). To mount to pole diameters up to 3 inches, other U-bolt
sizes may be used. For mounting to a flat surface, attach mounting bracket to the SU
using bolts supplied, and then mount to flat surface using your own hardware.
For mounting directly to a 1-1/2 inch or 1-3/4 inch pole, first attach the supplied
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. The RJ45 connector
does not “click” into the receptacle; it is held into place by the screw-on cap.
The following U-Bolt kits enable mounting to other than a standard size pole:
U-BOLT, 1 – 1 1/2" SCH 40 PIPE, 5/16-18 THD, ZINC/STEEL
U-BOLT, 1 1/4 - 1 3/4" SCH 40 PIPE, 5/16-18 THD, ZINC/STEEL
U-BOLT, 1 1/2 - 2" SCH 40 PIPE, 5/16-18 THD, ZINC/STEEL
U-BOLT, 2 – 2 1/2" SCH 40 PIPE, 5/16-18 THD, ZINC/STEEL
U-BOLT, 2 1/2 - 3" SCH 40 PIPE, 5/16-18 THD, ZINC/STEEL
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.

If the Frequency Plan is set to a fixed channel setting, it must be the same as the Base
Station and the following warning will be displayed.
Press OK to continue. After selecting “Save Settings and Install Subscriber Unit”, the
following screen appears and the SU searches for an outbound signal from a Base
Station. Point the SU in the direction of the BSU. Immediately after detecting a
signal, a short tone will be heard, followed by a series of “beeps” indicating the
strength of the BSU’s signal. If a BSU signal is not detected, slowly move the
pointing direction of the SU until the detection tone is heard. Then carefully center
(slowly move ODU both left & right) to the fastest repeating sound (beeps are almost
continuous). This would be the optimum setting for the SU’s ODU antenna. At the
PC where the software was loaded, the following screen also provides a relative
indication of the strength of the received signal which will coincide with the beeping
being more rapid the more the “Receive Signal Quality” meter moves it bar to the
right (Excellent).
Note: If the time to align the SU takes more than 15 minutes, the audible
sound will stop and the SU will attempt to connect with the BSU. If more than
15 minutes is required, disconnect and reconnect the power at the indoor
power supply (brick) to reset the 15-minute timer and re-start the above
process.

After maximizing the signal strength, click “OK” to continue the process of
establishing the wireless connection. The “Status” screen is displayed and the progress
of the connection with the BSU is shown in the Operating Status line. Other
communication link details are also shown.
The following are the typical series that would be encountered during the set-up and
antenna alignment stages:
1) “ODU not connected” until the SU cable is connected and power is applied.
2) “Searching for outbound” – point the SU to find a signal.
3) “Outbound detected” – point the SU to maximize the signal strength.

operating status of the communication
situation.
It is suggested that the Status screen be
used until the signal is peaked before
selecting the Status screen. While in
the connection process, the line to the
left of “status” rotates to indicate
continuous process action.
5) “Inbound acquired” - this may show only for a short moment.
6) “Link established” -congratulations – the link is ready!
Note:
If “Searching for outbound” and
“Outbound detected” are alternately
viewed, and the status never gets to
the “Searching for inbound” step, the
BSU is not acquirable with enough
signal level from the Subscriber
Unit.
If the message “Network control

ODU (J1) to Power Adapter Interface (J1)
The ODU J1 is an RJ-45 receptacle and the Power Adapter J1 connector is an 8-pin
DIN female receptacle. The functional and electrical interface is specified in Table 4-1
and Figures 4-2, 4-3, 4-4 and 4-5.

cable the RJ45 connector per the pin-out in Table 4-1. Then slide the plastic housing
over the RJ45 connector being sure to align the RJ45 clip into the proper side. Tighten
down the back of the connector for weather sealing and so the cable does not slip.
Finally, install the O-ring between the RJ45 connector and the knurled knob which
will be screwed tightly onto the connector on the back of the ODU after the RJ45
connector is properly seated.

If necessary to install or replace the above DIN connector, first put over the raw cable
the plastic parts in the order seen above and crimp the pins on the properly prepared
wire ends. Then slide the plastic housing over the metal part of the DIN connector
being sure to align it. This connector is then ready to plug into the Power Brick inside.
Alternative Method of Connection
Another method that is acceptable is to use what are called “jelly beans” or Telephone
Wire Tap Connectors. These moisture resistant and easy to install devices have been
used by the telephone industry for years both indoors and out (for this installation,
recommendation is for using only indoors). These can be purchased at many
electronic supply stores worldwide including Radio Shack (part #64-3081), Tandy or
through most well stocked DYI stores. For this method, you will need eight (8) of
these devices per cable.
Self-stripping tap connectors permit a continuous feed or
loop without interruptions and let you splice wires
without cutting any conductors. The connectors can be
used with 19-26 gauge wire and resist moisture.
Where you had to cut the cable for entry or egress, strip back the outer CAT5 cable
jacket about two (2) inches on each side of the cut – do not strip the individual wires
leaving bare copper! Into each 2-wire Tap Connector, push in the like colored wires
from each cable end firmly and equally into the Tap. While holding the wires in firmly,
squeeze the button with wide pliers to equally force the button into the Tap. If
properly done, the button will now be flush with the rest of the Tap Connector body
and the two wires will not pull out. Continue with the installation of seven (7) more of
these Taps being sure that each wire from the ends of each severed cables match
exactly in color per each Telephone-type Wire Tap Connector.
Refer to the table below that provides the details on each of the eight (8) wires that will
need to be spliced from one cable to the like color on the other cable. After
successfully installing the wire tap devices, the severed cable will carry the Ethernet
and voltages necessary for operation.

ETHERNET INTERFACE
The RJ45 Ethernet communications are compatible with ANSI/IEEE 802.3u, type
Ethernet-II 10/100Base-T, and IPv4. The SU ODU hardware contains a unique
MAC ID that is used for its Ethernet address.
NETWORK MODES
The SU supports the following three network operating modes: IP routing,
Ethernet bridging, and Ethernet bridging with VLAN tagging. These modes are
defined below. The Base Station controls the network mode, and the SU follows.
Network Mode
IP Routing
Ethernet Bridging
Ethernet Bridging with
VLAN Tagging
Description
The SU asserts itself as the network gateway, and
accepts for transmission all IP packets that are not meant
for the local network. Similarly, the SU filters the
downlink packets and selects only IP packets with
destinations that are known to be local. Local IP
addresses are either statically programmed into the SU,
or are learned by gleaning DHCP messages and
upstream traffic.
The SU accepts for uplink transmission all Ethernet
packets with destination addresses that are not on the
local network as learned from observing the source
addresses. Similarly, the SU filters the downlink packets
and selects only packets with local Ethernet destinations
that have been learned by observing local source
addresses.
The SU operates similar to the Ethernet bridging mode,
but tags uplink packets with a VLAN ID provided by the
BSU. The SU removes VLAN tags from downlink
Ethernet packets that are selected for output.
NETWORK CONFIGURATIONS
The SU is compatible with the network configurations shown in Figure 4-6. An
external hub or switch is required to provide Ethernet communications to more than
one host device; a host may be a computer, VoIP terminal, or other terminal that has
an IP and Ethernet MAC address. Each host device must be on the same subnet
when the IP-routing mode is used. A server, or router, implementing Network
Address Translation (NAT) protocols allows a single IP address of the wireless
network to be used to connect multiple devices. When Ethernet bridging mode
without VLAN-tagging enabled is used, a VLAN switch can be connected to separate
several VLANs through a single SU. When VLAN-tagging is enabled, a VLAN switch
is not necessary and a conventional hub or server can be used; however, the SU will
filter tags for only a single VLAN.

5 TROUBLESHOOTING
Regular Maintenance
There is no regular maintenance required except to keep the surfaces free from debris,
dirt and dust.
Problem – Solution Section
Problem:
“ODU not connected” is displayed.
Possible Causes:
Cable from power brick to ODU not connected
Power brick not turned on
Cable from power brick to PC is not connected, or is a cross-over cable
(should be straight)
Recommended Actions:
Recheck cable connections and wiring for cuts, etc. If possible, use another
cable assembly and re-try. Use a straight if crossed, and vice versa for the cable
between the power brick and your PC or LAN.
Problem:
“Outbound detection” does not occur, or “Searching outbound” is displayed
permanently.
5-1
T S U N A M I
M U L T I P O I N T
Possible Causes:
Improper radio settings (e.g. frequency plan or channel)
Signal blockage, severe path fading, or antenna misalignment
Interference (other 5.3/5.8 GHz transmitters nearby)
Recommended Actions:
Recheck subscriber unit set-up, etc. Redo the antenna alignment and be sure
to swing the antenna left and right significantly to be sure you are acquiring
the best signal level (go from no signal in each direction and center between
these two positions). May need to mount the ODU in a different location if
the signal is marginal (below 50) or is fluctuating (not a steady value). Check to
be sure the antenna is pointed to the intended BSU for the area.
Problem:
Status alternates between “Searching outbound” and “Outbound detection”.
Possible Causes:
Burst rate of the outbound signal exceeds the burst rate limit of the SU
Recommended Actions:
Upgrade to a faster model
See if there is another BSU available with a compatible burst rate
Problem:
“Inbound detection” does not occur
Possible Causes:
Interference at the BSU
