Basic Installation
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
detached 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 (A7 models) 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.
SU-R Installation Manual
BreezeACCESS II Series
Basic Installation
•
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 or UNI-8.5 antenna may also be attached
to a fixed window. Avoid metal obstacles such as metal window frames or metal film antiglare 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. For integral omni antennas (A model), make sure that the antennas are
BreezeACCESS II Series
SU-R Installation Manual
Basic Installation
extended upward vertically in relation to the floor to achieve vertical polarization. For the
detached UNI-7 or UNI-8.5 antenna (A7 model) follow the instructions included with the antenna.
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 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 box).
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.
In SU-R-A models with integral antennas, extend the antennas upward vertically in relation to the
floor to achieve vertical polarization.
2.6 Connecting the Antenna (A7 model)
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.
2.7 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.

Aligning the Antenna (A7 model)
4. ALIGNING THE ANTENNA (A7 MODEL)
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.
BreezeACCESS II Series
12
SU-R Installation Manual
Aligning the Antenna (A7 model)
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.

Appendix B: 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.

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
