• AUS: extended capabilities, the maximum number of association can be 25 CPE’s.
Limitations of BreezeACCESS VL Systems
• When operating in very noisy environments, the Automatic Noise Immunity mechanism (ANI) can
force the OFDM Weak Signal (OWS) to a level of '1'. In the event that this happens (on the AU
side) the SUs with SNRs below 25 dB can disassociate without being able to re-associate. In such
cases (very noisy environments) the ANI must be set to 'Manual' and the OWS value must never
be set to '1'.
• Data Encryption must be set in the same way throughout the cell in order to support traffic relay. If
the SU Data Encryption is enabled, then the AU Data Encryption must also be enabled.
• Units running SW version 4.5 or later with Country Code 1044 (Australia) should not be
downgraded to 4.0 or earlier; this can be performed only after changing the Country Code. The
above mentioned Country Code is supported only by version 4.5 and later.
• Prior to changing the Country Code, the user should verify that under the new EIRP conditions
imposed by the new Country Code, it is still possible to maintain the link (relevant in cases where
the new CC EIRP value is lower than the original EIRP value).
• When downgrading to previously released versions, the operator defaults might be corrupted. To
avoid this, the recommended downgrade procedure is:
1. Download the operator defaults (.cmr file)
2. Downgrade from current SW
3. Load the operator defaults
• Sensitivity may change slightly as a function of frequency (+/-2dB).
• Transmission power accuracy is +/-1dB above 8dBm @ antenna port (typical condition). At lower
levels the accuracy is +/-3dBm, never contradicting regulations. At very low levels the use of
ATPC may cause significant fluctuations in the power level of the transmitted signal. When
operating at such low levels, it is recommended to disable the ATPC Option in the SU and to set
the Transmit Power parameter to the average TX Power level before the ATPC was disabled.
• In units operating in the 5.3 GHz band, the following rules must be met for full compliance with
FCC regulations:
o For units with HW Revision B, frequency 5270MHz should not be used with a 20 MHz
bandwidth. For these units, the Transmit Power parameter in the AU, and the
Maximum TX Power parameter in the SUs served by this AU, should not be set to a
value above “17-Antenna Gain”.
o For units with HW Revision C, frequencies 5270 MHz, 5275 MHz and 5330 MHz
should not be used with a 20 MHz bandwidth. For these units, the Transmit Power
