BreezeACCESS MMDS Series 1 SU-I/ID Installation Manual
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS/MMDS SU-I
and SU-ID 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 MMDS 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/ID-MMDS line of Subscriber Units comprises compact units that are
designed for indoor installation. SU-I units include two 2dBi integrated antennas.
SU-ID units have two RF connectors for detached diversity antennas. Detached
antennas can be installed either indoors or outdoors, depending on the specific
site conditions.
The SU-I/ID-MMDS is available in two frequency bands:
SU-I/ID-MMDSa products operate in the 2.500 - 2.600 GHz frequency band.
SU-I/ID-MMDSb products operate in the 2.596 - 2.686 GHz frequency band.
The SU-I/ID-MMDS series includes the following products:
SU-I/ID-1D-MMDSa/b: supports a single Ethernet device
SU-I/ID-8D-MMDSa/b: supports up to eight Ethernet workstations/PCs
SU-I/ID-BD-MMDSa/b: supports a LAN (a bridge functionality)

8. Check the functionality of the unit as described in Chapter 6.
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. SU-ID units 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.
Basic Installation
SU-I/ID Installation Manual 4 BreezeACCESS MMDS Series
For most applications, the most convenient choice is to use SU-I units,
equipped with two integral 3dBi omni antennas.
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.
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.
Basic Installation
BreezeACCESS/MMDS Series 5 SU-I/ID Installation Manual
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
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.
Basic Installation
SU-I/ID Installation Manual 6 BreezeACCESS MMDS Series
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.
2.5 Wall Mounting the Unit

Aligning the Antenna
BreezeACCESS/MMDS Series 15 SU-I/ID 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/ID 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/ID 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.
L Type 3 (3Mbps) if the RSSI reading is higher than 76 units.
LL Type 2 (2Mbps) if the RSSI reading is between 66 to 76 units.
LLL 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. 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.

APPENDIX B. USING TELNET
Use the following procedure to connect to BreezeACCESS units via a Telnet
session.
1. Connect the PC to the Ethernet port of the unit (or the hub to which the unit
is connected) using a straight Ethernet cable. If you connect the PC directly
to a unit that is normally connected to a hub, use a crossed Ethernet cable.
You may also connect the PC to any Ethernet port on the network and
communicate with the unit to be managed via the wired or wireless media.
2. Make sure that the IP parameters of the PC are configured to enable
connectivity with the unit.
3. Run a Telnet application and use the IP address of the unit to be managed as
the Host Name.
4. Set Port to Telnet (this is the default).
5. Set Terminal Type to VT100 (this is the default).
6. Enter the Service Provider password.
7. When the password is recognized, the following message is displayed:
You have entered.
8. Press Enter, the Breeze ACCESS Monitor is displayed on the screen.
To exit the Telnet session, choose Disconnect from the Connect menu.
(The session is terminated automatically, after a specific time of inactivity
determined by the Log-out Timer).
