Introduction
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS 2.4 SU-A and
SU-E series of 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 effectively support IP-based services BreezeACCESS systems
employ wireless packet data switching technology.
The BreezeACCESS 2.4 line of products uses Frequency Hopping Spread
Spectrum radios that operate in Time Division Duplex (TDD) mode in the
2.400GHz – 2.500GHz frequency range.
SU-A and SU-E series Subscriber Units are comprised of an indoor unit (SU-NI)
and an outdoor unit. In the SU-A product line, the outdoor unit (SU-RA)
contains the radio module and an integral flat antenna. In the SU-E series, the
outdoor unit (SU-RE) contains the radio module and an interface to an external
antenna (not included). The indoor unit provides the interface to the user’s
equipment and is powered from the mains via its SU-PS power supply unit. The
SU-NI also contains an IF (Intermediate Frequency) module and is connected to
the outdoor unit via a 50-ohm coaxial IF cable. The IF cable serves for
transmission of the 440MHz IF signal between the indoor and the outdoor units.
It also serves for transferring power (12VDC), management and control signals
from the indoor unit to the outdoor unit.

2.4 Guidelines for Selection of Equipment Locations
Select appropriate locations for the Outdoor unit and for the Indoor unit using
the following guidelines.
SU-RA
•
The SU-RA Outdoor unit should be mounted on a pole and should be
installed on a rooftop or a side-wall where a direct line of sight with the Base
Station antenna can be established. The higher the unit, the better the
achievable link quality.
•
The antenna (integrated on the front side of the SU-RA Outdoor unit) should
be directed towards the Base Station. The unit should be installed in a way
that allows optimal alignment towards the Base Station. The location should
also be selected to allow easy access to the unit for installation and testing.
SU-RE
•
The SU-RE outdoor unit should be installed as near as possible to its antenna.
•
The antenna should be mounted on a pole and should be installed on a roof
top or side wall where a direct line of site with the Base Station can be
established. The higher the antenna, the better the achievable link quality.
•
The antenna should be directed towards the Base Station. The antenna
should be installed in a way that allows optimum alignment towards the Base
Station. The location of the antenna should allow easy access for installation
and alignment.
SU-RA/RE
•
The SU-RA/RE is connected to the SU-NI by means of an IF cable carrying
signaling, control signals and power. The IF frequency is 440 MHz. The
maximum allowed attenuation of the IF cable connecting the Outdoor unit to
the Indoor unit is 15dB and the maximum allowed DC resistance (the sum of
the DC resistance of the inner and outer conductors) is 1.5 ohm. This allows
for cable length of up to 30m when using the standard RG 58 cable.
If longer cables are required, a cable with lower attenuation and/or DC
resistance should be used. Table 2-1 provides details regarding some popular
cables such as the RG 58 and RG 213. If the spectral environment is polluted
with noise in the 440 MHz band, it is recommended to use a higher quality
BreezeACCESS 2.4 Series

Length (m)
•
The Indoor unit should be installed in as close as possible to the building’s
entry point of the IF cable. The location of the Indoor unit should also take
into account the need to connect it to a power mains outlet and to the CPE.
Notice: Outdoor units and antennas should be installed ONLY by experienced
installation professionals who are familiar with local building and safety
codes and, wherever applicable, are licensed by the appropriate government
regulatory authorities.
The system complies with the EN61000-4-5, level 3 (2kV) standard and is protected
against secondary lightning strikes when its outdoor unit is properly
grounded according to the applicable country-specific industry standards
for protection of structures against lightning. The use of any antenna other than
those certified with this product is forbidden in accordance to FCC rules 15.204.
Failure to do so may void the BreezeACCESS product warranty and may
expose the end user or the service provider to legal and financial liabilities.
BreezeCOM and its resellers or distributors are not liable for injury,
damage or violation of regulations associated with the installation of
outdoor units or antennas. Reffer to Appendix C for approved antennas.

Aligning the Antenna
4. ALIGNING THE ANTENNA
Note:
Antenna alignment using the RSSI bar display is possible only after the
Access Unit you wish to associate with is operational and the basic
parameters were properly configured (see Section 3.2). Otherwise the unit
will not be able to synchronize and associate with the Access Unit. As the
RSSI measurement is performed on received frames, its results are
meaningless as long as the unit is not associated with an AU.
1. Verify that the Power indication (the Yellow LED of the BSSI bar display)
is ON.
2. Align the antenna (integrated into the front side of the SU-RA Outdoor unit,
or separate if the unit is an SU-RE) to point towards the general direction of
the base station.
3. The RSSI bar display is located on the bottom panel of the Outdoor unit
(refer to Figure 2-6). The eight green RSSI LEDs are used for reading the
Received Signal Strength Indication. The higher the number of green LEDs
that are ON, the higher the level of the received signal. 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, at least one green LED should be ON. If you cannot
reach a point where at least one green LED is ON, try to improve the
reception quality by placing the antenna at a higher point or in a different
location.
Note:
In some cases (e.g., when the Subscriber Unit is very close to the Base
Station), the antenna might have to be installed at an appropriate angle, in
order to ensure that it is directed towards the Base Station antenna).
5. Tighten the bracket screws (or the U-bolts/metal band), firmly securing the
unit or the antenna to the pole.

RSSI MEASUREMENT AND MAXIMUM DATA
RATE CONFIGURATION
6.1 Performing the RSSI Measurement
The Continuous Link Quality Display test allows a continuously updated display
of the average Received Signal Strength Indication. As the test measures only the
desired signal of properly received frames, it is a good indication to the quality
of the received signal.
Note:
As the RSSI bar indicator is not accurate, it is recommended always to
perform the Continuous Link Quality Display test after the antenna was
optimally aligned.
1. Start the Monitor program as described in Section 3.1.
2. From the Main Menu Type 4 to access the Site Survey menu.
3. Type 4 to activate the Continuous Link Quality Display selection screen.
4. On the screen you will get a continuously updated display of RSSI
measurements. To stop the test, press the Esc key.

Appendix B
APPENDIX A. 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).

Appendix B
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.
•
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 this parameters (the higher the date
rate, the higher the error rate). The link quality can be estimated based on
the RSSI measurement at the SU, assuming that the RF link budgets are the
same for both directions. 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. If the
BreezeACCESS 2.4 Series
29

Appendix B
measured RSSI is less than a certain threshold, it is recommended to
decrease the Maximum Data Rate in accordance with the following table:
RSSI
(SU-A/E-2.4)
Recommended
Maximum Data Rate
RSSI > 108
3Mbps
95 > RSSI > 108
2Mbps
RSSI < 95
1Mbps
The default value is 3 Mbps. Allowed values are 1, 2 or 3 Mbps.
