Antenna Gain" (The maximum allowed EIRP for 5270 MHz and 20 MHz bandwidth is 17
dBm).
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 parameter in
the AU, and the Maximum Tx Power parameter in the SUs connected to this AU, should
not be set to a value above "20-Antenna Gain" (The maximum allowed EIRP for 5270
MHz, 5275 MHz and 5330 MHz with a 20 MHz bandwidth is 20 dBm).
For units with HW Revision C, frequency 5265 MHz should not be used with a 10 MHz
bandwidth. For these units, the Transmit Power parameter in the AU, and the Maximum Tx
Power parameter in the SUs connected to this AU, should not be set to a value above "25-
Antenna Gain" (The maximum allowed EIRP for 5265 MHz with a 10 MHz bandwidth is 25
dBm).

In BreezeACCESS VL units operating in the 4.9 GHz Japan band (not B&B point-to-point) with
a 10 MHz bandwidth, the following rules must be met for full compliance with regulations:
When operating at 4945 MHz, the Transmit Power parameter in the AU should not be set
to a value above 11 dBm. The Maximum Transmit Power of the SU should not be set to a
value above 10 dBm.
When operating at 5055 MHz, the Transmit Power parameter in the AU should not be set
to a value above 13 dBm. The Maximum Transmit power of the SU should not be set to a
value above 10 dBm.
This requirement, although not indicated in the certification document, is needed following the
tests performed in the certification lab.
•
The maximum number of SUs that can be served by an AU when Data Encryption is enabled
is 124. The number displayed for the Maximum Number of Associations is the value
configured for this parameter, which might be higher than the actual limit, indicated in the Show
Air Interface Parameters display.
•
When encryption is used by the Authentication Algorithm (Shared Key option), in large cells
(more than 80 SUs) the association process may be relatively long.
