SU A/E Subscriber Units Installation Manual
Introduction
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS MMDS 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 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.
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.
The SU-A/E-D-MMDS series include the following products:
•
SU-A/E-1D-MMDS: supports a single Ethernet device
•
SU-A/E-8D-MMDS: supports up to 8 Ethernet workstations/PCs
•
SU-A/E-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.

2.4 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.
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 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
double-shielded cable such as the LMR 240 or LMR 400 (manufactured by
Times Communications).

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.
Note:
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 ETS 300 385 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.
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.

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 ESSID,
Hopping Band and Frequency Offset parameters were properly configured.
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.

Appendix A. Using Telnet
APPENDIX A. USING TELNET
Use the following procedure to connect to BreezeACCESS MMDS 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).
