Chapter 1 - System Description
Introducing BreezeACCESS 900
BreezeACCESS 900 system allows operators that provide IP services
using BreezeACCESS II to extend the reach of their system and provide
services to clusters of customers that cannot otherwise be reached due
to being obstructed by heavy foliage or other obstacles. Operators can
benefit from the advantage of operating locally in the 900 MHz band,
being able to provide services to customers within a radius of half a mile
in non line of sight environments with heavy foliage.
BreezeACCESS 900 system includes the following components:
Cell Extension Equipment (CX): Provides the interface between the
local system operating in the 900 MHz band and the primary system
operating in the 2.4 GHz band.
Subscriber Units (CPE): BreezeACCESS Subscriber Units operating
in the 900 MHz band.
Alvarion also offers to its customers a special spectrum analysis tool to
enable optimal selection of frequencies and antenna polarization in the
heavily crowded 900 MHz band. For information on this tool, refer to
the Breeze Access Spectrum Analyzer User’s Guide.

Cell Extender
Cell Extender
The Cell Extender operates as an Access and Subscriber Unit that are
connected back-to-back. The Subscriber Unit component operated in
the 2.4 GHz band and provides connectivity to the primary
BreezeACCESS II base station. The Access Unit component operates in
the 900 MHz band and serves the Subscriber Units located in the area
covered by the Cell Extender.
The CX-2.4-900 Cell Extender is comprised of an Interface Unit, a
2.4 GHz Radio Unit and a 900 MHz antenna.
The Interface Unit includes the interface (indoor) unit of a
BreezeACCESS II Subscriber Unit and a BreezeACCESS 900 Access
Unit. These two units are connected to each other via a hub module. It
provides an interface for an optional local Ethernet connection and is
powered from the mains (110/220VAC).
The SU-RA-2.4 radio unit of the Subscriber Unit component
incorporates the radio module and an integrated flat antenna.
The Interface Unit is connected to the 2.4 GHz Radio Unit via a 50ohm
coaxial Intermediate Frequency (IF) cable. This cable carries 440 MHz IF
signals between the Interface Unit and the Radio Unit. In addition, this
cable transfers power (12 VDC) and control signals from the Interface
Unit to the Radio Unit.
The AU-900 Access Unit connects to an external antenna.
Both BreezeACCESS equipment in both the 2.4 GHz and 900 MHz
bands operate in Time Division Duplex (TDD) mode. It employs wireless
packet data switching technology, using Frequency Hopping Spread
Spectrum (FHSS) radios.

Chapter 1 - System Description
Subscriber Unit
The Subscriber Unit (SU) installed at the customer premises enables the
customer data connection to the Access Unit of the Cell Extender.
The Subscriber Unit provides an efficient platform for high speed
Internet and Intranet services. The use of packet switching technology
provides the user with a connection to the network that is always on,
enabling immediate access to services.
The SU-I-1D-A10-900 miniature Subscriber Unit is designed for
desktop or wall-mount installation. It supports a single Ethernet device
and connects to the customer’s data equipment via a standard IEEE
802.3 10Base-T (RJ-45) interface. The unit is powered from the
110/220 VAC mains. It has one RF connector for an outdoor wall-
mountable 10dBi antenna.

BreezeCONFIG( ACCESS
BreezeCONFIG ACCESS
The BreezeCONFIG ACCESS utility is an SNMP-based application
designed to manage BreezeACCESS system components and upgrade
unit software versions. The system administrator can use the
BreezeCONFIG ACCESS utility to control a large number of units from a
single location. BreezeCONFIG ACCESS provides a single point of
control for both BreezeACCESS II and BreezeACCESS 900 system
components. In addition, BreezeCONFIG ACCESS enables you to load
an updated configuration file to multiple units simultaneously, thus
radically reducing the time spent on unit configuration maintenance.

Chapter 2 - Installation
IF Cable
The SU-RA-2.4 Radio Unit is connected to the Interface Unit via an IF
cable carrying both signals and power. The IF frequency is 440 MHz.
The maximum permitted attenuation of the IF cable is 15dB at 440 MHz
and the maximum permitted DC resistance (the sum of the DC
resistance of the inner and outer conductors) is 1.5 ohms. This enables
a 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
Table 2-1: IF Cables
Cable Type RG 58 RG 213 LMR 200 LMR 240 LMR 400
Maximum Cable
Length (m)

provides detailed information about common 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 that a higher quality
double-shielded cable, such as the LMR 200, LMR 240 and LMR 400,
be used. (These cables are manufactured by Times Communications).
If you are using coaxial cables other than those listed above, consult the
cable manufacturers’ specification to ensure that the cable's

Installing the SU-I Subscriber Unit
Installation Guidelines
This section describes the installation guidelines and the various
considerations that must be taken into account when planning the
installation.
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 near as possible to the antenna. The
RF cable connecting the unit to the antenna should be as short as
possible to guarantee minimum power loss.
The location of the Subscriber Unit should take into account its
connection to a power outlet and the user’s data equipment.
Keep the units well away from sources of heat, such as radiators,
air-conditioners, etc.
Location of the Antenna
The antenna should be pole mounted on the roof-top or on a side
wall. It should be installed where it can be directed towards the
location of the Cell Extender. Any physical object in the path
between the unit and the Cell Extender should be avoided. Any
buildings or other physical structure such as hills or other natural
geographic features higher than the antenna and situated in the
path between the two sites can constitute obstructions.
WARNING
It is the responsibility of the professional installer to ensure that when using the
outdoor antenna kit, that only this antenna provided with the subscriber unit is
used along with the minimum cable lengths provided. The use of any antenna
other than those listed is expressly forbidden in accordance to FCC rules CFR47
part 15.204.
Antenna Polarization
Antenna polarization must be the same at both ends of the link. The
antenna can be mounted to provide either vertical or horizontal
polarization. To verify polarization of the antenna, refer to the mounting
instructions in Appendix B.
Manual Revision 1.0 - Preliminary
2-15
![](/img.php?id=334739&img=bg32.png)
Chapter 2 - Installation
Antenna Seal
The antenna connectors as well as other outdoors RF connections must
be sealed against rain.
Lightning Protection
Lightning protection is designed to protect people, property and
equipment by providing a path to ground for the lightning’s energy. The
lightning arrestor diverts the strike energy to the ground along a
deliberate and controlled path instead of allowing it to choose a random
path. Lightning protection for a building is more forgiving than
protection of electronic devices. A building can withstand up to 100,000
volts, but electronic equipment may be damaged by just a few volts.
Lightning protection entails connecting an antenna discharge unit (also
called an arrestor) to each cable as close as possible to the point where
it enters the building. It also entails proper grounding of the arrestors
and of the antenna mast (if the antenna is connected to one).
The lightning arrestor should be installed and grounded at the point
where the cable enters the building. The arrestor is connected to the
unit at one end and to the antenna at the other end.
The professional installer you choose must be knowledgeable about
lightning protection. The installer must install the lightning protector in
a way that maximizes lightning protection.
A Lightning and Grounding installation kit is available from Alvarion.
WARNING
ONLY experienced installation professionals who are familiar with local building
and safety codes and, wherever applicable, are licensed by the appropriate
government regulatory authorities should install outdoor units and antennas.
Failure to do so may void the BreezeACCESS product warranty and may expose
the end user or Service Provider to legal and financial liabilities. Alvarion and its
resellers or distributors are not liable for injury, damage or regulation violations
associated with the installation of Outdoor Units or antennas.

Aligning the Cell Extender’s SU-RA Antenna
Aligning the Cell Extender’s SU-RA
Antenna
The SNR bar display is located on the bottom panel of the SU-RA. The
eight green LEDs are used for indicating the quality of the received
signal. The higher the number of green LEDs indicating On, the higher
the quality of the received signal. This section describes how to align the
SU-RA antenna using the SNR bar display.
NOTE
Antenna alignment using the SNR bar display is possible only after the SU is
associated with an Access Unit. The associated Access Unit must be operational
and the basic SU’s parameters must be correctly configured. If not, the unit will
not be able to synchronize with the Access Unit. As the SNR measurement is
performed on received frames, its results are meaningless unless the SU is
associated with an Access Unit.
To align the SU-RA antenna:
1. Align the antenna, which is integrated into the front side of the
SU-RA unit, by pointing it in the general direction of the Base
Station.
2. Verify that the power indication of the unit is On.
3. Verify that the WLNK LED of the unit is On, indicating that the unit
is associated with an Access Unit. If the WLNK LED is Off, check
that the basic parameters are correctly configured. If the unit is still
not associated with the AU, improve the quality of the link by
changing the direction of the antenna or by placing the antenna at a
higher or alternate location.
4. Rotate the antenna until the maximum SNR reading is achieved,
where at least 1 green LED is on: If you encounter prolonged
difficulty in illuminating the minimum required number of green
LEDs, try to improve the reception quality by placing the antenna at
a higher point or in an alternate location.
5. Secure the unit firmly to the pole.
NOTE
If you are having difficulties in obtaining a good RSSI, since the RSSI bar
indicator is not precise, it is recommended that you use the Continuous Link
Quality Display test for more precise alignment of the antenna.

Aligning the SU-I Subscriber Unit’s
Antenna
For antenna alignment, you can use either the 3 Signal Quality LED
indicators on the front panel of the SU-I or view the Received Signal
Strength Indication in the Site Survey menu. Typically, alignment using
the Signal Quality LEDs is sufficient. This section describes how to
align the SU-RA antenna using the Signal Quality LEDs.
NOTE
Antenna alignment using the Signal Quality LEDs is possible only after the SU is
associated with a Cell Extender’s AU. The Cell Extender’s AU must be operational
and the basic SU’s parameters must be correctly configured. If not, the unit will
not be able to synchronize with the Cell Extender’s AU. As the SNR measurement
is performed on received frames, its results are meaningless unless the SU is
associated with a Cell Extender’s AU.
To align the antenna of the SU:
1. Align the antenna by pointing it in the general direction of the Cell
Extender.
2. Verify that the power indication of the unit is On.
3. Verify that the WLNK LED of the unit is On, indicating that the unit
is associated with an Access Unit. If the WLNK LED is Off, check
that the basic parameters are correctly configured. If the unit is still
not associated with the Cell Extender’s AU, improve the quality of
the link by changing the direction of the antenna or by placing the
antenna at a higher or alternate location.
4. Check the SIGNAL QUALITY L, M and H LEDs. The higher the
number of LEDs that are on, the better the quality of the link.
Rotate the antenna left and/or right until you reach the point of
highest signal quality reading on the SIGNAL QUALITY LEDs. For
proper operation, at least one (L) LED should be on. If this is not
possible, improve the link quality by placing the antenna at a higher
point or in an alternate location.
5. Secure the antenna firmly to the pole.

selected hopping frequencies and the current hopping sequence (based
on the previous selections made before the last reset). The new

Flexible Hopping Definition Mode
Frequencies Selection and Basic
Sequence Generation Using the Flexible
Hopping Definition Menu
The Flexible Hopping Definition menu includes the following options:
Define Sub-Bands
The Define Sub-Bands option enables defining a new list of sub-bands
and/or discrete frequencies. Enter a list of the required sub-bands
and/or frequencies, using either sub-bands (f1-f2) or discrete
frequencies, e.g. 904-910,915,919-925. use a comma to separate
between entries, do not use spaces.
The usable center frequencies are from 904 to 926, using a 1 MHz
resolution (904, 905, 906,…926). However, the channel spacing, which
is the minimum distance between two consecutive frequencies, is
2 MHz. Thus, for example, the sequence 904,905 is not a valid entry
because the distance between frequencies is less than 2 MHz, and it will
be rejected.
When entering discrete frequencies, the actual center frequencies are
defined. When entering a sub-ban, a guard band of 1 MHz on both sides
is included, which means that the sub-band entries can start at 903
and end at 927. Defining for example the sub-band 903-909 will result
in selecting the frequencies 904, 906, 908. The same set of frequencies
(904, 906, 908) will be selected also if the defined sub band is 903-910.
Defining the sequence 904-910,915,919-927 will result in selecting the
frequencies 905, 907, 909, 915, 920, 922, 924 and 926.
The new selected set of frequencies (frequencies to be used) will become
effective only after the next reset.
Scrambling Definition
The Scrambling Definition menu enables defining the method of
organizing the selected frequencies to form the actual hopping sequence
to be used. Proper organization of the hopping sequence is essential to
guarantee minimal cross interference among several neighboring cells
that use the same sequence with different Hopping Shift values.
Scrambling Mode
Manual Revision
D-3
Defines the scrambling mode. The following options are available:
![](/img.php?id=334739&img=bg52.png)
Appendix D - Configuring Hopping Frequencies and Operational Sequences
Standard Scrambling
This mode is not recommended for sequences with 7 or more channels.
The scrambled basic sequences for 3 to 6 frequencies when using
Standard Scrambling are:
Table D-1: Basic Sequences using Standard Scrambling
N (number of channels) Scrambled Basic Sequence (channel indexes)
3 1, 3, 2
4 1, 3, 2, 4
5 1, 3, 5, 2, 4
6 1, 3, 5, 2, 6, 4
Frequency 1 (index=1) is the lowest frequency in the list of frequencies
to be used, frequency 2 is the next frequency and so on.
Manual Scrambling
For customized definition of the hopping sequence, using the Manual
Sequence Definition option (see below).
Enhanced Scrambling
Automatically generates hopping sequences using an enhanced
algorithm. It is recommended that Enhanced Scrambling rather then
Standard Scrambling be used. If the Enhanced Scrambling Mode is
selected, the Spanning Factor parameter (see below) must be configured
in the AU. The Enhanced Mode is not suitable for sequences with 6 or
less frequencies. If Enhanced Scrambling is selected with sequences
that have 6 or less frequencies, than Standard Scrambling is used by
default.
The scrambled sequence is generated according to the following rules:
1. The first channel in the basic scrambled sequence is frequency 1
(Frequency 1 (index=1) is the lowest frequency in the list of
frequencies to be used, frequency 2 is the next frequency and so on.)
2. The index of each of the other channels is calculated by adding the
Spanning Factor to the index of the previous channel. Note that the
sequence is cyclic, meaning that adding 1 to the highest index in the
sequence (Index=N where N is the number of channels in the
sequence) will result in the first channel (Index=1).
BreezeACCESSS 900 System Manual
D-4
![](/img.php?id=334739&img=bg53.png)
Flexible Hopping Definition Mode
The scrambled basic sequence can also be calculated using the formula:
Px (j)= {[(j-1)*X]mod(N)}+1
Where:
X is the Spanning Factor
N is the number of channels in the sequence (modulus)
J is the sequence index
Example: N=8, X=3
P1(5)={[(1-1)*3}mod8}+1=1
P2(5)={[(2-1)*3}mod8}+1=6
od8}+1=5
od8}+1=2
P7(5)={[(7-1)*3}mod8}+1=7
P8(5)={[(8-1)*3}mod8}+1=4
And the basic scrambled sequence is: 1, 4, 7, 2, 5, 8, 3, 6.
Manual Sequence Definition
Manually defines the hopping sequence, using numbered channel
indexes (from 1 to “Number of Hopping Frequencies”). The sequence
length must be equal to “Number of Hopping Frequencies” (all the
defined frequencies must be used).
Erase Manual Sequence
Erases the manually defined hopping sequence.
Spanning Factor (AU only)
Defines the Spanning Factor to be used by the Enhanced Scrambling
mechanism. The Spanning Factor should be chosen so that the GCD
(Greater Common Divisor) of the Spanning Factor and the Number of
Hopping Frequencies would be 1 (e.g. for 8 frequencies possible values
for the Spanning Factor are 1, 3, 5 and 7). The SU learns the value of
the Spanning Factor from the AU during the association process.
Use of different spanning factors by non-synchronized neighboring base
stations reduces the probability of interference between adjacent
sectors.
P3(5)={[(3-1)*3}mod8}+1=3
