RF Warning
To comply with FCC RF exposure requirements in section 1.1307, a minimum separation distance of
2m (79 inches) is required between the antenna and all persons.
Line Voltage
Before connecting this instrument to the power line, make sure that the voltage of the power source
matches the requirements of the instrument.
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

Introduction
BreezeACCESS 2.4 Series 1 BS Equipment Installation Manual
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS 2.4 base station
equipment, including the stand-alone AU-E/A-NI-2.4 Access Units and the
modular AU-E/A-BS-2.4 Units with the BS-SH rack mounted shelf.
The BreezeACCESS IP Broadband Wireless Local Loop (WLL) 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 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.
The AU-A/E-NI and the AU-A/E-BS Access Units are comprised of an indoor
unit and an outdoor unit. In the AU-A-NI and AU-A-BS products, the outdoor
unit (AU-RA) contains the radio module and an integral flat antenna. In the
AU-E-NI and AU-E-BS products, the outdoor unit (AU-RE) contains the radio
module and an interface to an external antenna (not included).
The indoor unit of the AU-A/E-NI is a stand-alone unit (AU-NI) that is powered
from the mains via its AU-PS power supply unit. The indoor unit of the AU-A/E-
BS is a module (BS-AU) that is designed for insertion into the BS-SH shelf. The
BS-SH, which is a 3U shelf suitable for installation in 19"racks, can contain up
to six BS-AU active modules and one or two BS-PS power supply modules. The
shelf is powered from a –48VDC power source. Power supply redundancy is
supported through the optional use of a second BS-PS power supply module.
The indoor unit provides the interface to the network. It 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.
Note: The information contained in this manual is applicable to
BreezeACCESS 2.4 units with software release 2.5 and up.

• Ethernet cable(s) (straight, one for each AU)
• Antenna(s)* and RF cable(s)* (AU-E-NI or AU-E-BS only)
• A portable PC with terminal emulation software
• Installation tools and materials.
Items marked with an asterisk (*) are available as options from BreezeCOM.
2.4 Guidelines for Selection of Equipment Location
Select appropriate locations for the equipment using the following guidelines:
• The outdoor unit can be pole—or wall mounted. Its location should allow
easy access to the unit for installation and testing.
• The AU-RA unit with its integrated antenna, or the external antenna
connected to the AU-RE unit, should be installed where it provides coverage
of all subscriber units in the area it is intended to serve. The higher the AU-
RA or the antenna, the better coverage it can provide.

Basic Installation
BS Equipment Installation Manual 4 BreezeACCESS 2.4 Series
• The AU-RE outdoor unit should be installed as near as possible to its
antenna.
Note: The distance between any two antennas should be greater than 40 cm.
• The outdoor unit is connected to the indoor unit by means of a coaxial IF
cable carrying signals, controls and power. The IF frequency is 440 MHz.
The maximum allowed attenuation of the IF cable is 15dB and its maximum
allowed DC resistance (the sum of the DC resistance of the inner and outer
conductors) is 1.5 ohm. This allows for cable lengths 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 data regarding several industry-standard cables such as
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 LMR 240 or LMR 400 (manufactured by Times
Communications).

Length (m) 30 100 65 150
• The BS-SH and its modules and the SU-NI are designed for indoor operation,
i.e., inside buildings, a suitable cabinet or a shelter. Air temperature control
might be necessary – the equipment is designed to operate over the
temperature range 0°C to 45°C.

Basic Installation
BreezeACCESS 2.4 Series 5 BS Equipment Installation Manual
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 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.Refer to Appendix C for approved antennas.

2.5 Installing the Outdoor Radio Unit
2.5.1 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 rear of the unit, allowing use of the 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 2-1 shows the locations of the U-bolt holes, band grooves and screw holes
on the rear side of the unit.
Figure 2-2 illustrates the method of installing an AU-RE unit on a pole using the
supplied brackets and open-ended screws. The installation of an AU-RA unit
with an integral antenna is very similar to the installation of an SU-RE unit.
Note: Make sure to install the unit with the bottom panel (the panel with the IF
connector) facing downward.

1. Connect one end of the grounding cable to the Ground terminal and connect
the other end to a good ground connection.
2. Connect the coaxial cable to the IF connector. Verify that the length of the IF
cable is sufficient and that it can easily reach the Indoor unit.
Note: Make sure to switch OFF the power of the indoor unit prior to
connecting/disconnecting the IF cable.
