BreezeACCESS MMDS Series 1 SU-I-D Installation Manual
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS-MMDS SU-I
Subscriber Units.
The BreezeACCESS IP Broadband Wireless Local Loop (WLL) system allows
access service providers to provide high-speed IP connectivity services to their
subscribers. To support IP-based services effectively BreezeACCESS systems
employ wireless packet data switching technology.
The BreezeACCESS 2.5 line of products uses Frequency Hopping Spread
Spectrum radios that operate in Time Duplex Division (TDD) mode in the
2.500GHz – 2.686GHz frequency range.
The SU-I-D-MMDS line of Subscriber Units comprises compact units that are
designed for indoor installation. Antennas can be installed either indoors or
outdoors, depending on the specific site conditions. The SU-I-D-MMDS series
include the following products:
• SU-I-1D-MMDS: supports a single Ethernet device
• SU-I-8D-MMDS: supports up to eight Ethernet workstations/PCs
• SU-I-BD-MMDS: supports a LAN (a bridge functionality)
Note: The information contained in this manual is applicable to BreezeACCESS
MMDS units with software release 2.3.

2.3 Installation Overview
Standard installation involves the following steps:
1. Verify that all components of the packing list, described in Section 2.1, are
intact and verify availability of the required items listed in Section 2.2.
2. Install the unit and antenna(s) in optimal locations as described in
Section 2.4.
3. Connect the antenna(s) to the unit as described in Section 2.6.
4. Connect the power supply to the unit as described in Section 2.7.
5. Connect the Ethernet port to the unit as described in Section 2.7.
6. Configure the basic system parameters as described in Section 3.
7. Align the antenna(s) for optimal connectivity and configure the Maximum
Data Rate if applicable, as described in Chapters 4 and 5.
8. Check the functionality of the unit as described in Chapter 6.
Antennas for Indoor Applications
For most indoor applications, the best choice is the standard unit equipped with
its screw-on 2dBi antennas. The units are small, easy to install and cover a large
area.
In some installations, it is required to install the unit and antenna separately. In
such instances, use the omni-6 antenna kit (6dbi omni-directional antenna with 3
meter RG-58 cable). In the USA (FCC regulated) and in non-regulated countries,
the omni-6 comes with a shorter antenna cable, extending the coverage area.
The Uni-8.5 is also useful in indoor applications. It is very small and easily wall-
mounted, but its radiation pattern is limited (75°).
BreezeCOM recommends that, for indoor applications, you use two antennas per
unit to utilize the diversity gain of the system.
Basic Installation
SU-I-D Installation Manual 4 BreezeACCESS-MMDS Series
2.4 Installation Guidelines
This section describes the installation guidelines and the various considerations
that must be taken into account when planning the installation.
2.4.1 Location of the Unit and Antenna(s)
• The unit can be placed on a shelf, or can be attached to the ceiling or a wall
using a mounting bracket. The unit should be installed as near to the
antenna(s) as possible to minimize loss of RF power in the cable(s).
• Keep the units well away from sources of heat, such as radiators, air-
conditioners, etc.
2.4.2 Location of the Antenna(s)
• Any physical object in the path between two units can cause signal
attenuation. Common obstructions are buildings and trees. If a unit’s
antenna is installed indoors, the walls and/or windows between the two
sites are physical obstructions. If the antenna is positioned outdoors, any
buildings or other physical structure such as trees, mountains or other
natural geographic features higher than the antenna and situated in the path
between the two sites can constitute obstructions.
• Install indoor antennas as close as possible to a window (or wall if a
window is not accessible) facing the required direction. Avoid metal
obstacles such as metal window frames or metal film anti-glare windows in
the transmission path. Install outdoor antennas high enough to avoid any
obstacles, which may block the signal.
• Position the antennas clear of metal furniture and away from moving metal
objects such as metal fans or doors.
• For best performance, position the antennas clear of radiation sources that
emit in the 2.5 - 2.7 GHz frequency band, such as microwave ovens.
Basic Installation
BreezeACCESS MMDS Series 5 SU-I-D Installation Manual
2.4.3 Antenna Diversity
In applications where no multipath propagation is expected, a single antenna is
sufficient to ensure good performance levels. However, in cases where multipath
propagation exists, BreezeCOM recommends that two antennas be used. This
takes advantage of space diversity capabilities. By using two antennas per unit,
the system can select the best antenna on a per-packet basis (every several
milliseconds).
Multipath propagation is to be expected when there are potential reflectors
between the Access Unit and Subscriber Units. These reflectors may be buildings
or moving objects such as airplanes and motor vehicles. If this is the case, the
radio signal does not travel in a straight line, but is reflected or deflected off of
the object, creating multiple propagation paths.
When installing a single antenna, modify the transmit diversity option to either
antenna 1 or antenna 2, according to the antenna being used.
2.4.4 Antenna Polarization
Antenna polarization must be the same at either end of the link. In most
applications, the preferred orientation is vertical polarization. Above-ground
propagation of the signal is better when it is polarized vertically. To verify
antenna polarization, refer to the assembly instructions supplied with the antenna
set. For screw-on and detached omni antennas, make sure that the antennas are
extended upward vertically in relation to the floor to achieve vertical
polarization.
2.4.5 Antenna Seal
When using outdoor antennas, you must seal the antenna connectors against rain.
Otherwise the antennas are not suitable for use in outdoor installations.
2.4.6 Lightning Protection
Lightning protection is designed to protect people, property and equipment by
providing a path to ground for the lightning’s energy. The lightning arrestor
diverts the strike energy to ground through a deliberate and controlled path
instead of allowing it to choose a random path. Lightning protection for a
Basic Installation
SU-I-D Installation Manual 6 BreezeACCESS-MMDS Series
building is more forgiving than protection of electronic devices. A building can
withstand up to 100,000 volts, but electronic equipment may be damaged by just
a few volts.
Lightning protection entails connecting an antenna discharge unit (also called an
arrestor) to each cable as close as possible to the point where it enters the
building. It also entails proper grounding of the arrestors and of the antenna mast
(if the antenna is connected to one).
The lightning arrestor should be installed and grounded at the point where the
cable enters the building. The arrestor is connected to the unit at one end and to
the antenna at the other end.
The professional installer you choose must be knowledgeable about lightning
protection. The installer must install the lightning protector in a way that
maximizes lightning protection. BreezeCOM offers the following high-quality
lightning arrestor assembly:
BreezeACCESS AL 1 Lightning Arrestor - Part No. 872905 5 ft (1.5m), “N”
Male to “N” Female.
Note: Detached antennas, whether installed indoors or out, should be installed
ONLY by experienced antenna installation professionals who are familiar
with local building and safety codes and, wherever applicable, are licensed
by the appropriate government regulatory authorities.
Failure to do so may void the BreezeACCESS Product Warranty and may
expose the end user to legal and financial liabilities. BreezeCOM and its
resellers or distributors are not liable for injury, damage or violation of
government regulations associated with the installation of detached
antennas.

Aligning the Antenna
BreezeACCESS MMDS Series 15 SU-I-D Installation Manual
4. ALIGNING THE ANTENNA
Omni and low gain antennas do not require alignment due to their wide radiation
pattern. High gain antennas have a narrow beamwidth, necessitating an alignment
procedure in order to optimize the link.
For Subscriber Units with directional antenna(s), you can either use the LED
indicators on the front panel of the unit or view the Received Signal Strength
Indication (RSSI) on the monitor. In most installations, alignment using the
LEDs is sufficient. The RSSI reading can be used when finer alignment is
required.
Note: Antenna alignment of the Subscriber Unit is possible only after the Access
Unit you wish to associate with is operational and the ESSID was properly
configured.
4.1 Aligning the Antenna Using the LEDs
1. Synchronize the units by aligning the antenna manually to point to the base
station until the WLNK indicator LED on the front panel of the unit
illuminates.
2. Rotate the antenna left and/or right until you reach the point of signal quality
reading on the quality (QLT) LEDs. The higher the number of illuminated
LEDs the better is the quality of the link. Make sure that at all times, the
front of the antenna faces the general direction of the Access Unit.
3. For proper operation, at least one (L) LED should be illuminated. If this is
not possible, improve the link quality by placing the antenna at a higher
point or in a different location.
4. After the antenna is optimally aligned, tighten the U-bolts (or metal band) to
secure the antenna to the pole.
Aligning the Antenna
SU-I-D Installation Manual 16 BreezeACCESS-MMDS Series
4.2 Aligning the Antenna Using the Site Survey Menu
1. Start the Monitor program as described in Section 3.1.
2. From the main menu, type 4 to access the Site Survey menu. Type 4 to start
the Continuous RSSI Display. Each line in the display includes the number of
frames that were received since the last measurement (total Rx) and the
average RSSI for these frames.
3. Rotate the antenna left and/or right until you reach the point of maximum
RSSI reading. Make sure that at all times, the front of the antenna faces the
general direction of the Base Station.
4. For proper operation, the RSSI reading should be at least 52 units. When the
maximum reading is less than 52 units, try to improve it by placing the
antenna at a higher point or in a different location. For best performance it is
recommended that the RSSI be higher than 76.
5. Press the Esc key to stop the test.
6. Tighten the U-bolts (or metal band) over the antenna to secure it to the pole.
Maximum Data Rate Configuration
BreezeACCESS MMDS Series 17 SU-I-D Installation Manual
5. MAXIMUM DATA RATE CONFIGURATION
1. If the average RSSI reading using the Average RSSI Continuous Display is
lower than 76, the default data rate of 3 Mbps is too high and the data rate of
the unit should be configured accordingly:
2. From the main menu, type 3 to access the Basic Configuration menu. Type 5
to access the Maximum Data Rate menu.
i) Type 3 (3Mbps) if the RSSI reading is higher than 76 units.
ii) Type 2 (2Mbps) if the RSSI reading is between 66 to 76 units.
iii) Type 1 (1Mbps) if the RSSI reading is lower than 66 units.
3. Reset the unit for the new configuration to become effective.

APPENDIX A. OPTIONAL RF ACCESSORIES
This appendix introduces some of the accessories available for specific
installations, and describes how to install them.
A.1 TPA 24 Transmit Power Amplifier (Booster)
The TPA 24 Transmit Power Amplifier is used to amplify the transmit power to a
fixed output of 24 dBm (250 mW). The TPA 24 is especially useful when long
RF cable runs are required. In addition, the TPA 24 simplifies antenna alignment
by enabling the use of wider dispersion transmit antennas. The TPA 24 is
internally protected against lightning and voltage surge protection.
The TPA 24 comes in two models:
• The TPA 24 NL receives input power in the range of -10dBm to 0dBm.
• The TPA 24 NH receives an input power of 0dBm to +10dBm.
Both models amplify the input power to a fixed output level of 24dBm (250mW).
The TPA is powered by 12VDC carried from the power inserter by the RF cable.
Note: The TPA 24 is not available in the USA due to FCC regulations.
When used in compliance with ETSI regulations, the TPA 24 can be connected to
cables and antennas resulting in a total transmitted power of 20dBm (100 mW) EIRP.
Appendix A
BreezeACCESS MMDS Series 23 SU-I-D Installation Manual
A.1.1 Installing the TPA 24
1. Choose one of the TPA 24 models according to the power level at the input
of the booster. In general the NH model is used. For installations with long
cables (high attenuation), the NL model should be used.
2. Choose one of the antenna connectors to be used for transmission.
3. Use the terminal to set the unit’s transmit diversity option to the selected
antenna.
Figure A-1. TPA 24 Installation
4. Connect the TPA 24 RF output directly to the transmit antenna.
5. Attach the TPA 24 RF input to the Power Inserter with the RF cable. The
Power Inserter must be installed indoors.
6. Connect the RF cable leading from the Power Inserter to the transmit antenna
on the BreezeACCESS unit.
Appendix A
SU-I-D Installation Manual 24 BreezeACCESS-MMDS Series
7. Plug the power cable leading from the Power Inserter into any available
110/220V outlet. The power supply must be installed indoors.
8. For reception, use a separate antenna connected to the other antenna
connector of the BreezeACCESS unit.
Note: Installations exceeding regulations set by local authorities expose the
installer and the user to potential legal and financial liabilities.

A.2 LNA 10 Low Noise Receive Amplifier
The LNA 10 is a high-performance, low-noise preamplifier designed to enhance
fringe area reception and provide additional gain on the receive antenna. Its
exceptionally small size and light weight enables it to be directly mounted on the
antenna by means of the female RF IN connector. Power is obtained through an
RG-59 coaxial cable connected to the power supply. The LNA 10 is internally
protected against lightning and voltage surge protection.
The Power Supply (PS) and Power Inserter are supplied with the LNA 10.
The RG-59 coaxial cable with F-type connector is not supplied and must be
purchased separately.
A.2.1 Installing the LNA 10
Before installing the LNA 10, the following steps must be taken:
1. Choose one of the antenna connectors to be used for reception. This
connector is called the receive antenna of the unit. The other connector is
called the transmit antenna of the unit.
2. Use the terminal to set the unit’s transmit diversity option to the selected
antenna (see Section). This prevents transmission from going through the
LNA 10.
3. Connect the LNA 10 RF input directly and as close as possible to the receive
antenna.
4. Attach the LNA 10 RF output directly to the RF cable going down to the
receive antenna connector on the BreezeACCESS unit.
5. Connect the RG-59 coaxial cable which leads down to the Power Inserter to
the Signal and Power out connector on the LNA 10.
6. Connect the Power Inserter to the power supply (both are indoor units).
7. For transmission, use a separate antenna connected to the other antenna
connector (transmit antenna) of the BreezeACCESS unit.

A.3 RFS 122 Radio Frequency Splitter
The RFS 122 Radio Frequency Splitter is used to split the RF signal generated by
a transmitter into two signals. These signals are then sent to two different and
independent antennas. The RFS 122 enables radio transmission using two
directional antennas connected to the same port of the BreezeACCESS unit.
Similarly, the splitter is used to combine two receiving antennas to one antenna
connector.
Before installing the RFS 122, use the terminal to configure the unit’s transmit
diversity option to transmit through Antenna 2 only, and connect the RFS 122 to
antenna connector 2.

A.4 AL 1 Lightning Arrestor
The AL 1 Lightning Arrestor is used to protect transmitters and receivers from
transients originating from lightning or EMP.
The AL 1 is gas tube-based and is not radioactive. The gas discharge tube can
sustain several transients if the time period between transients is sufficient to
allow the tube to cool down.

A.5 AMP 2440 Bi-Directional Amplifier
The AMP 2440 is a bi-directional amplifier designed for extending the range of
BreezeACCESS wireless LAN radios.
The unit operates automatically, therefore there is no need for manual
adjustments. The units receive signal gain and also provide transmit power
amplification.

Figure A-5. AMP 2440 Functional Block Diagram
The amplifier is installed directly at the antenna’s feed point, providing
maximum effectiveness of transmit power which compensates for signal loss in
the transmitter cable to the antenna. Likewise, the Low Noise Amplifier (LNA)
in the AMP 2440 boosts the receive signal right at the antenna prior to
experiencing the loss in the transmission cable to the radio. This gain also
overcomes the losses in the transmission cable between the amplifier and the
radio. In fact, use of the AMP 2440 bi-directional amplifier will actually increase
the receiver sensitivity of the radio by 4dB. The ultimate result is the best
possible noise figure and maximum receiver sensitivity. System gains of up to 30
dB are typical when amplifiers are used at each end of a link.
The AMP 2440 bi-directional amplifier is completely weatherproof and can be
bolted to the antenna mast or tower leg using the U-bolt included. The connectors
face down so that gravity will drain all water away from the amplifier enclosure.
This will prevent water from settling on the face of the unit. Likewise, since the
Appendix A
BreezeACCESS MMDS Series 33 SU-I-D Installation Manual
LEDs are also facing downward they can be checked for operation from the
bottom of the mast.
DC Power to the amplifier is supplied through the transmission cable, using an
indoor power supply and DC Injector. The amplifier unit also contains its own
integral lightning protection and DC surge protection to ensure years of
continuous outdoor operation.
BreezeCOM provides the user with two models of the AMP 2440 bi-directional
amplifier:
• AMP 2440-500. Provides 500 mW (+27dBm) maximum output
• AMP 2440-250. Provides 250 mW (+24dBm) maximum output
The transmit gain for both models is 12 - 15dB. Full output power of
approximately 500 mW is achieved with 30 mW (+15 dBm) input to the
amplifier; 8 mW (+9dBm) for the AMP 2440-250 model. The amplifier goes into
limiting at this point and higher input power results in only slight increases in the
output power. Up to 100 mW of power may be safely applied directly to the
amplifier input without any damage on either model.
The AMP 2440 bi-directional amplifier comes with power supplies that have
standard 2.1 mm barrel plugs (which are configured as positive (+) tip and
negative (-) outer conductor). Although normally supplied with a power supply,
any regulated 12 Volt DC 1 amp supply can be used. The power supply can be
used with 110 or 240 VAC power.
A.5.1 Installing the AMP 2440 Bi-Directional Amplifier
The AMP 2440 bi-directional amplifier is designated for installation by
professional radio installers. Several key factors unique to the particular
installation determine the power level at the input of the amplifier. The most
important consideration is the cable loss in the transmission cable between the
radio and the pole mounted amp. The installer should understand these and other
factors when computing the input power to the amplifier.
The AMP 2440 bi-directional amplifier can be mast mounted using the steel U-
bolt included with the unit, as shown in Figure A-7. The AMP 2440 bi-
Appendix A
SU-I-D Installation Manual 34 BreezeACCESS-MMDS Series
directional amplifier should be installed with the connectors facing downward.
After placing the assembly on the mast, use an open-end wrench to carefully
tighten the nuts. Take care not to over-tighten the nuts or you may inadvertently
strip the threads.
Figure A-6. AMP 2440 Installation and Mounting
WARNING! It is very important to waterproof the RF connectors on the AMP
2440 bi-directional amplifier.
However, it is recommended that you do not seal the connectors until after all
system tests have been performed. Be sure to use the high quality weather
resistant vapor wrap included with you amplifier kit to seal all the outside
connections.
The DC Power Injector is not in a waterproof enclosure and must be protected
from the weather. It can be permanently mounted to a surface using the mounting
flanges.
Note: When using the 24dB gain dish antenna in the United States, the external
filter (P/N: SPF-1) must be installed to comply with FCC emission
requirements.
