Introduction
BreezeACCESS Series 1 Base Station Equipment Installation Manual
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS base station
equipment, including the stand-alone AU-E/A-NI-Access Units and the modular
AU-E/A-BS-Units with the BS-SH rack mounted shelf.
The BreezeACCESS Broadband Wireless Access 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 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.

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
BreezeACCESS Series 5 Base Station Equipment Installation Manual
• 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).

• 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
Base Station Equipment Installation Manual 6 BreezeACCESS Series
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. The system complies with
EN 61000-4-5, test level 3 (2kV).
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.

Appendix B. Basic Parameters
BreezeACCESS Series 33 Base Station Equipment Installation Manual
APPENDIX B. BASIC PARAMETERS
The following parameters are relevant to all BreezeACCESS products.
• 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.
• DHCP Client
⇒ DHCP Options – Displays the current status of the DHCP (Dynamic
Host Configuration Protocol) support, and allows selecting a new
operation mode. The available options are:
∗ Disable – Use manual procedure for configuring the IP
parameters.
∗ DHCP Only – Search for a DHCP Server and obtain the IP
parameters from it (IP Address, Subnet Mask and Default
Gateway Address).
Appendix B. Basic Parameters
Base Station Equipment Installation Manual 34 BreezeACCESS Series
∗ Automatic – Search for a DHCP Server for configuration of
the IP parameters. If a DHCP Server is not found within
approximately 40 seconds, use the currently configured IP
parameters.
The default is Disable.
⇒ Access to DHCP - To define the port through which the unit is
allowed to communicate with a DHCP server. The options are the
following:
∗ From Wlan Only
∗ From Ethernet Only
∗ From Both Ethernet & Wlan
The default for an Access Unit is From Ethernet Only. The
default for a Subscriber Unit is From Wlan Only.
Parameters Specific for BreezeACCESS II
The following parameters are set in BreezeACCESS II products.
• Hopping Sequence – Displays the Hopping Sequence of the unit.
A hopping sequence is a pre-defined series of channels (frequencies) that are
used in a specific, pseudo-random order as defined in the sequence. The unit
“hops” from frequency to frequency according to the selected sequence.
When more than one AU is co-located in the same area, it is recommended to
assign different hopping sequences to each AU.
Hopping Sequences are grouped in three hopping sets (see Hopping Set
parameter below). When setting up multiple AUs in the same site, always
choose hopping sequences from the same Hopping Set to reduce the
possibility of collisions on the wireless media. This parameter is only set in
the AU. All the SUs learn it from the AU during the association process.
The permitted range depends on the applicable hopping standard (see Table
5-1 on the next page). The default value is 1.
Appendix B. Basic Parameters
BreezeACCESS Series 35 Base Station Equipment Installation Manual
• Hopping Set – Displays the selected hopping set. Each hopping standard has
3 hopping sets. The hopping set selected in this screen determines which
hopping sequences are available in the Hopping Sequence screen. Always
use the same hopping set per site (with different hopping sequences) to
minimize the possibility of collisions on the wireless media. The default
value is 1.
This parameter is set only in the AU. All the associated SUs learn its value
from the AU during the association process.
• Hopping Sync (BS-AU only) – Displays the current Hopping Sync status of
the unit and allows defining a new status. When several AUs that use the
same hopping set and different hopping sequences are co-located, their
operation should be synchronized in terms of hopping sequence initialization
and timing. One unit must be specified as a Master Unit and all other units
must be specified as Slave units. Available options are:
⇒ Idle – No synchronization (stand-alone operation)
⇒ Master – The AU that serves as a Master unit providing
synchronization signals to the Slave units
⇒ Slave – An AU that operates as a Slave
The default is Idle.
Note: Synchronization is not allowed by the radio regulations in certain
countries. In units using such standards, the Hopping Sync option is
not supported. See Table 5-1 for information on synchronization
support in the standards of various countries.

Appendix B. Basic Parameters
BreezeACCESS Series 37 Base Station Equipment Installation Manual
Parameters Specific for BreezeACCESS MMDS
The following parameters are set in BreezeACCESS MMDS products.
• Hopping Shift –Displays the current value of the hopping shift parameter
and allows entry of a new hopping shift value. This parameter is available
only in Access Units – the Subscriber Units learn it during the association
process.
When several Access Units that use the same hopping frequencies are
collocated, the Hopping Shift parameter is used to define a different hopping
sequence for each AU. The target is to achieve a minimal level of cross
interference between AUs through maintaining a minimal distance of 3 MHz
between the frequencies used by adjacent AUs at any given moment. Thus,
the collocated AUs should use different hopping shifts.
The available range for hopping shifts is dependent on the number of
frequencies selected and is equal to the number of hopping frequencies -1
(minus 1). The Hopping Shift parameter does not have any effect when using
a single frequency. The default value of the Hopping Shift parameter is 0.
• Flexible Hopping Definition – Allows adding and removing frequencies to
the list of hopping frequencies; displays the selected hopping frequencies and
the current hopping sequence (based on the previous selections made before
the last Reset). The new selections will come into effect only after the next
Reset.
The Flexible Hopping is based on using the standard MMDS 6MHz channels
and frequencies. See Appendix C for a detailed list of the standard channels,
as well as the frequency band and the hopping frequencies for each of these
channels.
The Flexible Hopping menu includes the following options, allowing
adding/removing standard MMDS channels or adding/removing discrete
standard hopping frequencies.
Appendix B. Basic Parameters
Base Station Equipment Installation Manual 38 BreezeACCESS Series
⇒ Add Frequencies – Allows adding discrete hopping frequencies or
frequency ranges. Enter a list of frequencies and/or frequency ranges
to be added, e.g. 2501.500,2407.500-2519.500, 2525.500.Use a
comma to separate between entries (no spaces). The allowed entries
are from 2500 to 2688 in steps of 0.5MHz. The frequencies (either the
start and stop frequencies of a range or discrete frequencies) can be in
the following formats:
MHz Resolution, e.g. 2520
kHz resolution, e.g. 2501.000,2505.500 (you must enter 3 digits after
the dot).
The minimal channel spacing between frequencies is 3MHz. When
entering a range, this will be the default channel spacing (e.g. for the
range 2510-2516 the hopping frequencies will be 2510, 2513 and 2516
MHz).
It is recommended to use the standard MMDS frequencies. See
Appendix C for a list of the standard MMDS frequencies.
⇒ Remove Frequencies - Allows removing frequencies from the
existing list. Enter a list of frequencies and/or frequency ranges to be
removed, using the same guidelines as in Add Frequencies above
⇒ Add Channels – Allows defining a new list of channels or adding
channels to an existing list. Enter a list of channels to be added, e.g.
A1,B3,D2. Use a comma to separate between entries (no spaces). See
Appendix C for a list of the channels and the hopping frequencies for
each of the channels.
⇒ Remove Channels – Allows removing channels from existing list.
Enter a list of channels to be removed, using the same guidelines as in
Add Channels above.
⇒ Erase All – Allows erasing all the entries from the list.
⇒ Show Flexible Hopping Parameters – Allows viewing the following
information:
∗ An updated list of the defined sub-bands and discrete frequencies
to become effective after the next Reset. A sub-band is defined by
the first and last hopping frequency in a series of consecutive
frequencies, with 3MHz separation between frequencies.
Appendix B. Basic Parameters
BreezeACCESS Series 39 Base Station Equipment Installation Manual
∗ An updated list of all the hopping frequencies to be used after the
next Reset.
∗ The current sequence of operational hopping frequencies
• Hopping Sync (BS-AU only) – Displays the current Hopping Sync status
of the unit and allows defining a new status. When several AUs that use the
same frequencies and different Hopping Shifts are co-located, their
operation should be synchronized in terms of Hopping Shift initialization
and timing. One unit must be specified as a Master Unit and all other units
must be specified as Slave units. Available options are:
⇒ Idle – No synchronization (stand-alone operation)
⇒ Master – The AU that serves as a Master unit providing
synchronization signals to the Slave units
⇒ Slave – An AU that operates as a Slave
The default is Idle.
Parameters Specific for BreezeACCESS XL
The following parameters are only relevant to BreezeACCESS XL products.
Note: The Hopping band and Hopping Offset parameters are applicable for
applications that use a 2MHz channel spacing. For other channel spacing
values, or for hopping bands/frequency configurations that are not
supported by the standard Hopping Band values, use Flexible Hopping
Definition as described on page 41.
• Hopping Band – Displays the current bandwidth and allows entry of a new
bandwidth. The bandwidth is determined based on the specific conditions of
the license to use a given frequency band, and on other considerations. The
available selections are 10, 12, 14, 24, 28, 36, 42 and 50 MHz (some
selections are not available in models with a total available bandwidth lower
than 50 MHz). In addition, a Single Channel selection is also available.
Appendix B. Basic Parameters
Base Station Equipment Installation Manual 40 BreezeACCESS Series
• Frequency Offset – Displays the current offset of the Hopping Band from
the beginning of the available frequency range, and allows entry of a new
offset. The offset is measured in channels, where each channel is 2 MHz. For
example, in products operating in the 3.5a band (3.410-3.452 GHz uplink), a
Frequency Offset of 5 (10 MHz) will cause the hopping band to start at 3.420
GHz for the uplink and at 3.520 GHz for the downlink. The maximum value
of the Frequency Offset is determined by the overall available bandwidth and
the selected Hopping Band (Hopping Band should be selected before
selecting the Frequency Offset).
The default Frequency Offset is 0.
When setting this parameter, consider the following relationship:
Max. Frequency Offset (channels) = (Overall Bandwidth-Hopping Band)/2.
For example, in products operating in the 3.5a band with an overall
bandwidth of 42 MHz, if the selected Hopping Band is 12 MHz then the
allowed range for Frequency Offset is from 0 to 15 channels.
Notes: In Single Channel mode, using the minimum (0) and the maximum
values of the Frequency Offset parameter will result in transmitting at
the edges of the band without using any guard band.
The Frequency Offset parameter does not have any effect on the
Flexible Hopping mode.
• Hopping Shift – Displays the current Hopping Shift parameter and allows
entry of a new value. Available only in AUs. All the associated SUs learn
the value of the Hopping Shift parameter from the AU during the association
process. The Hopping Shift parameter is used to provide different operational
hopping sequences when several co-located Access Units use the same band
(and hence the same basic hopping sequence). This minimizes the cross
interference among these AUs and sallow for better spectrum utilization.
Each unit represents a shift of one channel between hopping sequences. The
allowed range depends on the defined band.
When setting this parameter, consider the following relationship.
Max. Hopping Shift (channels) = Number of hopping frequencies-1.
The default Hopping Shift is 0. The minimum recommended shift between
two adjacent AUs is 2.
Appendix B. Basic Parameters
BreezeACCESS Series 41 Base Station Equipment Installation Manual
• Flexible Hopping Definition– Allows defining the sub-bands to be used;
displays the selected sub-bands, the hopping frequencies that will be used as
a result of these selections and the current hopping sequence (based on the
previous selections made before the last Reset). The new settings will go into
effect only after the next Reset.
Note: The algorithm that determines the operational hopping sequence (the
actual hopping sequence based on rearranging the order of the
selected hopping frequencies) when using Flexible Hopping Definition
is different than the one used when fixed Hopping Bands are selected,
even when the selected set of hopping frequencies is the same.
Therefore, all units in the same base station (all AUs and associated
SUs) must use the same hopping frequencies selection method (fixed
Hopping Band or Flexible Hopping Definition).
The Flexible Hopping mode is intended primarily for use in cases where the
operating band cannot be defined by the Hopping Band and Frequency Offset
parameters. This includes the following instances:
⇒ When the bandwidth of the operating band is different from the standard
bands available in the Hopping Band menu.
⇒ When the operating band is comprised of two or more non-continuous
bands.
⇒ When the required Channel Spacing is other than 2MHz.
The Flexible Hopping menu includes the following options:
⇒ Channel Spacing – Allows defining a new value for the Channel
Spacing parameter, if the unit supports selection between several channel
spacing values. Some models may support only a single value for the
Channel Spacing parameter, in which case this parameter is not available.
The Channel Spacing parameter defines the minimum distance between
consecutive hopping frequencies. In addition, the Channel Spacing
parameter also determines the guard band, which is the distance of the
first hopping frequency in each sub-band from the beginning of the sub-
band, as well as the minimum distance of the last hopping frequency in
each sub-band from the end of the sub-band.

The available selections in products that support all the options are 1,
1.75 and 2MHz. In some products only a subset of these options may be
available. The default is 2MHz.
Note: Changing the value of the Channel Spacing will erase the current
list of defined Sub-bands/frequencies
⇒ Define Sub-bands – Allows 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.
3410-3418,3425,3430-3434. The frequencies (either the start and stop
frequencies of a sub-band or discrete frequencies) can be in the following
formats:
∗ MHz Resolution, e.g. 3420
∗ kHz resolution, e.g. 3430.250, 3445.500, 3412.000 (you must enter 3
digits after the dot)
When using a Channel Spacing of 1 or 2 MHz, the entries should be on a
1MHz grid (e.g. 3410, 3413).
When using Channel Spacing of 1.75MHz, the usable frequencies are on
a grid of 0.250MHz, the first one being at a distance of 0.750MHz from
the beginning of the radio band. Therefore, for products using the 3.5a
band, the usable frequencies (uplink) are 3410.750, 3411.000,
3411.250……
This is also the list of valid entries for discrete frequencies. When
defining sub-bands, the entries must be on a grid of 0.250MHz that starts
at the beginning of the radio band. Therefore, for products using the 3.5a
band, the list of valid entries for defining discrete frequencies as well as
sub-bands’ start and end frequencies, is 3410, 3410.250, 3410.500…….
Appendix B. Basic Parameters
BreezeACCESS Series 43 Base Station Equipment Installation Manual
Use a comma to separate between entries. Use a hyphen to define sub-
bands (no spaces).
When a discrete frequency is defined, it is the actual hopping frequency
to be used. When a sub-band is defined, the hopping frequencies are
determined by the value of the Channel Spacing parameter (see Channel
Spacing above).
Note: Channel Spacing parameter should be configured prior to
defining a new set of sub-bands.
The entries are frequencies in the lower radio band (uplink frequencies,
except for 3.8GHz products where the downlink frequencies should be
used).
The following are invalid combinations and will be rejected:
∗ Two overlapping sub-bands, e.g. 3410-3420,3418-3422.
∗ Combinations trying to force a distance between channels smaller
than the Channel Spacing, e.g. 3420.500, 3421.000(with a Channel
Spacing of 1.75MHz).
Examples:
∗ The selected sub-band is 3419-3431MHz. The Channel Spacing is
2MHz. The hopping frequencies are: 3420, 3422, 3424, 3426,
3428 and 3430MHz. (6 frequencies)
∗ The selected sub-band is 3419-3431MHz. The Channel Spacing is
1MHz. The hopping frequencies will be: 3420, 3421, 3422, 3423,
3424, 3425, 3426, 3427, 3428, 3429 and 3430MHz (11
frequencies)
∗ The selected sub-band is 3419-3430MHz. The Channel Spacing is
1.75MHz. The hopping frequencies will be 3419.750, 3421.500,
3423.250, 3425.000, 3426.750 and 3428.500 (6 frequencies). Note
that the actual used band (including the o.750MHz guard bands) is
only 3419-3429.250MHz.
Appendix B. Basic Parameters
Base Station Equipment Installation Manual 44 BreezeACCESS Series
Note: The hopping frequencies are calculated for each sub-band
separately. Therefore, the hopping frequencies calculated for
two consecutive sub-bands may differ from the hopping
frequency calculated for a single “combined” band (e.g. the
result for the entries 3410-3420,3420-3420 may differ from
the results for the entry 3410-3430).
• Hopping Sync (Access Unit only) – Displays the current Hopping Sync
status of the unit and allows defining a new status. When several AUs that
use the same sub-bands and different Hopping Shifts are co-located, their
operation should be synchronized in terms of hopping sequence initialization
and timing. One unit must be specified as a Master Unit and all other units
must be specified as Slave units. Available options are:
⇒ Idle – no synchronization (stand-alone operation)
⇒ Master – The AU that serves as a Master unit providing
synchronization signals to the Slave units
⇒ Slave – An AU that operates as a Slave

Use the Transmit Power Control parameter to change the gain of the Tx power
circuits as required. A value of 15 represents the highest transmit power level.
A lower value represents a lower transmit power level. The allowed range is from
0 to 15. The default value is 15 (maximum power). The effect of this parameter
on the transmitted power is not linear. In addition, it is affected by the length
(attenuation) of the IF cable.
Table D- 3 on the next page displays transmit power control parameters values
required to decrease the transmitted power by approximately 5 dB, 10 dB and 15
dB as a function of cable length (refers to RG-58).
