SU-R Installation Manual 1 BreezeACCESS MMDS Series
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS MMDS SU-R Subscriber Units.
The BreezeACCESS Broadband Wireless Access 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 Division Duplex (TDD) mode in the 2.500GHz – 2.686GHz frequency
range.
The SU-R-MMDS line of Subscriber Units comprises compact units that are designed for indoor
installation. SU-R units are available in several models differing from each other in the type of
supported data networks and availability of voice services as follows:
• SU-R-8D units support up to 8 Ethernet workstations / PCs (8 MAC addresses).
• SU-R-BD units provide a full bridge functionality supporting up to 512 MAC addresses.
• SU-R-8D1V support up to 8 Ethernet workstations / PCs and have an interface to a standard
telephone set.
SU-R-MMDS units are available either with an indoor wall/window mountable 7 dBi UNI-7
antenna (-A7 models) or with an adapter for an external separate antenna.

SU-R Installation Manual 3 BreezeACCESS MMDS Series
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 in optimal locations as described in Sections 2.4 and 2.5 and in
the instructions supplied with the antenna.
Note: To avoid drilling unnecessary holes, it is recommended to verify good connectivity with the
base station prior to drilling holes in the locations intended for the SU-R unit and/or the
indoor antenna.
3. Connect the antenna to the unit as described in Section 2.6.
4. Connect the power supply and the user’s equipment to the unit as described in Section 2.7 .
5. Configure the basic system parameters as described in Section 3.
6. Align the antenna for optimal connectivity and configure the Maximum Data Rate if
applicable, as described in Chapters 4 and 5.
7. 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
• The unit can be placed on a desktop or a shelf, or can be attached to a wall.
• The unit should be installed as neat as possible to the antenna (-A7 models). The RF cable
connecting the unit to the antenna should be as short as possible to guarantee minimum power
loss.
Basic Installation
BreezeACCESS MMDS Series 4 SU-R Installation Manual
• Keep the units well away from sources of heat, such as radiators, air-conditioners, etc.
2.4.2 Location of the Antenna
• 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. The UNI-7 antenna may also be attached to a fixed
window. 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.
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
Basic Installation
SU-R Installation Manual 5 BreezeACCESS MMDS Series
with the antenna set. For the detached UNI-7 antenna (A7 model) follow the instructions included
with the antenna.
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.
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.
AL 1 Lightning Arrestor - Part No. 872905 5 ft (1.5m), “N” Male to “N” Female is available from
BreezeCOM.
Note: Detached outdoors antennas 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.
Basic Installation
BreezeACCESS MMDS Series 6 SU-R Installation Manual
2.5 Wall Mounting the Unit
Note: To avoid drilling unnecessary holes, it is recommended to verify connectivity with the base
station prior to drilling holes in the locations intended for the SU-R unit and/or the indoor
antenna.
The drill template on the packaging box can be used to mark the locations of the screws on the
wall (drill right through the markings on the drill template).
After insertion of the anchors and screws, hang-on the unit on the two screws with the bottom
panel (the side with the connectors) facing downward.
2.6 Connecting the Antenna
1. Connect the special adapter to antenna port 1 (marked 1) on the side of the unit. Push the
adapter carefully into the hole using the alignment markings on the adapter and the unit, and
turn it 180 degrees to firmly lock it.
2. Connect the antenna cable to the adapter. If you use a heavy cable, secure the cable so as to
prevent applying excessive force on the adapter and connector.
2.7 Connecting the Unit to the Power Supply and to the CPE
The unit operates on a power input of 5V DC, supplied by the power transformer included with
the unit.
1. Plug the output jack of the power transformer into the DC input jack (marked DC IN)
located on the bottom panel of the unit.
2. Connect the supplied universal power transformer to a power outlet - 110/ 220VAC.
3. Use a straight Ethernet 10BaseT cable to connect the Ethernet port (marked ETH) to a PC or
to a hub’s uplink port. Use a crossed cable to connect to a hub.
4. For units with voice support, use the standard cable connected to the telephone set to
connect the telephone to the telephone port (marked TEL).

Aligning the Antenna
BreezeACCESS MMDS Series 12 SU-R Installation Manual
4. ALIGNING THE ANTENNA
When using high gain antennas with a narrow beam width, an alignment procedure is necessary in
order to optimize the quality of the link with the Access Unit.
For a Subscriber Unit with a directional antenna, you can either use the LED indicators on the
front panel of the unit or view the Received Signal Strength Indication (RSSI) using the monitor
program. In most installations, alignment using the LEDs is sufficient. The RSSI reading can be
used when finer alignment is required (see 3.2).
Note: Antenna alignment of the Subscriber Unit is possible only after the Access Unit you wish to
associate with is operational and the basic parameters were properly configured as
described in Section 3.2.
4.1 Aligning the Antenna Using the LEDs
1. The H (high), M (medium) and L (low) LEDs on the front panrel of the unit indicate the
quality of the link. The higher the number of illuminated LEDs the better is the quality of the
link.
2. Rotate the antenna left and/or right until you reach the point of maximal signal quality
reading on the H, M and L LEDs. Make sure that at all times, the front of the antenna faces
the general direction of the Access Unit. In some cases, e.g. when the unit is very close to
the base station you may need to tilt the antenna upward or downward.
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, secure the antenna to guarantee that it will remain in
the selected position.
4.2 Aligning the Antenna Using the Site Survey Menu
1. Start the Monitor program as described in Section 3.1.
Aligning the Antenna
SU-R Installation Manual 13 BreezeACCESS MMDS Series
2. From the main menu, type 4 to access the Site Survey menu. Type 4 to start the Continuous
Link Quality 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 (or tilt it upward/downward) 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 38 units. When the maximum
reading is less than 43 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 65.
5. Press the Esc key to stop the test.
6. Secure the antenna to guarantee that it will remain in the selected position.
Maximum Data Rate Configuration
BreezeACCESS MMDS Series 14 SU-R Installation Manual
5. MAXIMUM DATA RATE CONFIGURATION
1. If the average RSSI reading using the Continuous Link Quality Display (see Section 4.1) is
lower than 65, the unit should be configured in accordance with the following table:
RSSI Recommended
Maximum Data Rate
RSSI > 65 3Mbps
53 < RSSI < 65 2Mbps
RSSI < 53 1Mbps
2. From the main menu, type 3 to access the Basic Configuration menu. Type 5 to access the
Maximum Data Rate menu.
• Type 3 (3Mbps) if the RSSI reading is higher than 65 units.
• Type 2 (2Mbps) if the RSSI reading is between 53 to 65 units.
• Type 1 (1Mbps) if the RSSI reading is lower than 53 units.
3. Reset the unit for the new configuration to become effective
See Appendix C for more details on the Maximum Data Rate parameter.

to connect to the Internet.
6.4 Verifying Telephone Connectivity (units with voice support)
To verify correct operation of the telephone, a test telephone with the default telephony
parameters and a known IP address should be connected to the system (the location of the test
telephone is determined by the system administrator).
Perform the following steps to verify telephone connectivity:
1. Use IP dialing to call the test telephone: dial * followed by the 12-digit IP address of the test
telephone. Verify connectivity. During the conversation, verify that other party has your IP
address.
2. After terminating the call, the other party should use the test telephone to call your IP
address and verify that the telephone, including the ringing circuits, functions properly.

Appendix C. Basic Parameters
SU-R Installation Manual 25 BreezeACCESS MMDS Series
Appendix C. Basic Parameters
• IP Address – Displays the current IP address of the unit and allows entry of a new IP address
(4 x 3 digit octets, separated by dots). The default IP Address is 010.000.000.001.
• Subnet Mask – Displays the current subnet mask of the unit and allows entry of a new
subnet mask (4 x 3 digit octets, separated by dots). The default mask is 255.000.000.000.
• Default Gateway Address – Displays the current address of the default gateway of the unit
and allows entry of a new default gateway address (4 x 3 digit octets, separated by dots). The
default gateway address is 000.000.000.000.
• DHCP Client
⇒ DHCP Options – Displays the current status of the DHCP (Dynamic Host Configuration
Protocol) support, and allows selecting a new operation mode. The available options are:
∗ Disable – Use manual procedure for configuring the IP parameters.
∗ DHCP Only – Search for a DHCP Server and obtain the IP parameters from it (IP
Address, Subnet Mask and Default Gateway Address).
∗ Automatic – Search for a DHCP Server for configuration of the IP parameters. If a
DHCP Server is not found within approximately 40 seconds, use the currently
configured IP parameters.
The default is Disable.
⇒ Access to DHCP - To define the port through which the unit is allowed to communicate
with a DHCP server. The options are the following:
∗ From Wlan Only
∗ From Ethernet Only
∗ From Both Ethernet & Wlan
The default for an Access Unit is From Ethernet Only. The default for a Subscriber Unit is
From Wlan Only.
• ESS ID – The ESSID (Extended Service Set ID) of the unit (up to 32 printable ASCII
characters). The ESSID is a string used to identify a wireless network. It prevents the
unintentional merging of two co-located wireless networks. An SU can only associate with an
AU that has an identical ESSID. Use different ESSIDs to segment the wireless access network
and add security to your network. The default value is ESSID1.
Appendix C. Basic Parameters
BreezeACCESS MMDS Series 26 SU-R Installation Manual
Note: The ESSID string is case-sensitive.
• Maximum Data Rate – Displays the current maximum data rate, and allows entry of a new
value for the maximum data rate.
BreezeACCESS units operate at 1 Mbps, 2 Mbps or 3 Mbps. Under certain conditions
(compatibility reasons or range/speed trade-off), you may decide to limit the use of higher
rates. If the quality of the link is not good enough, it is recommended to decrease the value of
these parameters (the higher the date rate, the higher the error rate). Otherwise, there is a high
probability that the unit will have to retransmit many frames several times before temporarily
reducing the data rate. A high number of retransmissions reduces the overall throughput for
the selected SU as well as for all the other SUs served by the same AU.
The link quality can be estimated based on the RSSI measurement using the Continuous Link
Quality Display in the SU. If the measured RSSI is less than a certain threshold, it is
recommended to decrease the Maximum Data Rate of the SU in accordance with the following
table:
Recommended Maximum Data Rate 3Mbps 2Mbps 1Mbps
BreezeACCESS MMDS SU-I/ID RSSI>65 53<RSSI<65 RSSI<53
The default value is 3 Mbps. Allowed values are 1, 2 or 3 Mbps.
The AU learns the Maximum Data Rate used by each SU during the association process, and
uses this rate for transmissions to the specific SU.
• Flexible Hopping Definition – Allows adding and removing frequencies to the list of
hopping frequencies; displays the selected hopping frequencies and the current hopping
sequence (based on the previous selections made before the last Reset). The new selections
will come into effect only after the next Reset.
The Flexible Hopping is based on using the standard MMDS 6MHz channels and frequencies.
See Appendix C for a detailed list of the standard channels, as well as the frequency band and
the hopping frequencies for each of these channels.
The Flexible Hopping menu includes the following options, allowing adding/removing
standard MMDS channels or adding/removing discrete standard hopping frequencies.
Appendix C. Basic Parameters
SU-R Installation Manual 27 BreezeACCESS MMDS Series
⇒ Add Frequencies – Allows adding discrete hopping frequencies or frequency ranges.
Enter a list of frequencies and/or frequency ranges to be added, e.g. 2501.500,2507.500-
2519.500, 2525.500.Use a comma to separate between entries (no spaces). The allowed
entries are from 2500 to 2688 in steps of 0.5MHz. The frequencies (either the start and
stop frequencies of a range or discrete frequencies) can be in the following formats:
MHz Resolution, e.g. 2520
kHz resolution, e.g. 2501.000,2505.500 (you must enter 3 digits after the dot).
The minimal channel spacing between frequencies is 3MHz. When entering a range, this will
be the default channel spacing (e.g. for the range 2510-2516 the hopping frequencies will
be 2510, 2513 and 2516 MHz).
It is recommended to use the standard MMDS frequencies. See Appendix C for a list of the
standard MMDS frequencies.
⇒ Remove Frequencies - Allows removing frequencies from the existing list. Enter a list of
frequencies and/or frequency ranges to be removed, using the same guidelines as in Add
Frequencies above
⇒ Add Channels – Allows defining a new list of channels or adding channels to an existing
list. Enter a list of channels to be added, e.g. A1,B3,D2. Use a comma to separate
between entries (no spaces). See Appendix C for a list of the channels and the hopping
frequencies for each of the channels.
⇒ Remove Channels – Allows removing channels from existing list. Enter a list of channels
to be removed, using the same guidelines as in Add Channels above.
⇒ Erase All – Allows erasing all the entries from the list.
⇒ Show Flexible Hopping Parameters – Allows viewing the following information:
∗ An updated list of the defined sub-bands and discrete frequencies to become effective
after the next Reset. A sub-band is defined by the first and last hopping frequency in a
series of consecutive frequencies, with 3MHz separation between frequencies.
∗ An updated list of all the hopping frequencies to be used after the next Reset.
∗ The current sequence of operational hopping frequencies
• Transmit Antenna – Displays which antennas are used for transmission. SU-R units support
transmit antenna diversity (2 antennas). During reception, a BreezeACCESS unit that is
connected to two antennas dynamically selects the antenna where reception is optimal. In
contrast, if the transmit antenna diversity is enabled, the unit selects the antenna from which it

BreezeACCESS MMDS Series 28 SU-R Installation Manual
will transmit before the actual transmission. It usually uses the antenna last used for
successful transmission. In installations where a model that can support antenna diversity is
connected to a single antenna, Transmit Antenna Diversity should be configured to transmit
only from that single antenna. Available selections are:
⇒ Use Two Antennas
⇒ Use Antenna No. 1
⇒ Use Antenna No. 2
The default selection is Use Antenna No. 1 for SU-R units where a single antenna is
connected to antenna port 1.
