Radio
The instrument transmits radio energy during normal operation. To avoid possible harmful exposure to
this energy, do not stand or work for extended periods of time in front of its antenna. The long-term
characteristics or the possible physiological effects of Radio Frequency Electromagnetic fields have
not been yet fully investigated.
Antenna Installation and Grounding
Be sure that the Outdoor unit, the antenna and the supporting structure are properly installed to
eliminate any physical hazard to either people or property. Verify that the antenna mast is grounded so
as to provide protection against voltage surges and static charges. Make sure that the installation of the
Outdoor unit, antenna and cables is performed in accordance with all relevant national and local
building and safety codes.

Introduction
BreezeACCESS 2.4 Series 1 SU-A/E Subscriber Units Installation Manual
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

Basic Installation
SU-A/E Subscriber Units Installation Manual 8 BreezeACCESS 2.4 Series
double-shielded cable such as the LMR 240 or LMR 400 (manufactured by
Times Communications).
Table 2-1: IF Cables
Cable Type RG 58 RG 213 LMR 240 LMR 400
Maximum cable
Length (m) 30 100 65 150
• 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.

2.5 Installing the Outdoor Unit
2.5.1 Pole Mounting the Outdoor Unit
The Outdoor unit can be secured to the pole using one of the following options:
• Special brackets and open-ended screws (supplied with each unit). There
are two pairs of screw holes on the back of the unit, allowing use of the
special brackets with various pole widths.
• U-bolts – size A (inner installation holes, up to 2” pole).
• U-bolt – size B (outside installation holes, up to 3” pole).
• Metal bands (9/16” wide, minimum 12” long)
Figure 2-3 shows the locations of the u-bolt holes, band grooves and screw holes
on the rear side of the Outdoor unit.
Figure 2-4 illustrates the method of installing an SU-RA Outdoor unit on a pole,
using the brackets and open-ended screws.
Figure 2-5 illustrates the method of installing an SU-RE Outdoor unit on a pole,
using the brackets and open-ended screws.
Note: Make sure to install the unit with the bottom panel (the panel with the IF
connector) facing downward.
