BreezeAIR system supports two types of antennas:
Integrated antenna
External antenna
Selecting the antenna model is according to the required range and performance.
Note: To comply with the regulation EIRP limits, the outdoor unit-transmit power
needs to be adjusted according to the installed antenna gain. Therefore a
professional installation of the transmitter is required. The outdoor unit must
be configured at the time of installation by qualified personnel. Fail to
comply with regulation rules may expose the installer to legal liabilities.
IMPORTANT! On lab/office tests of links with external antennas, connection should
be done via the antennas. In case direct connection is required (with
RF cables), make sure to have a minimum of 50dB attenuation on the
RF cables to avoid any damage to the radios.

The outdoor unit transmit power is configurable. The unit limits the max transmit power
according to the antenna gain, the regulation and the frequency band. The installer, if
needed, can select a lower power.
Regulation of the unit defines the frequency band supported by the units:
FCC: 2.5GHz, 4.9GHz, 5.8 GHz.
ETSI: 3.x GHz, 5.4 GHz and 5.8 GHz.
Mexico: 4.95-4.99 GHz, 5.15-5.35 GHz, 5.8 GHz and 10GHz.
Other regulation.
The unit supports two levels of privilege password: regular user and administrator user.
Since Tx power level affect compliance of the unit with regulation rules, precautions are
built into the system to keep the end user from adjusting the Tx power level above the
regulation limits. Therefore, the following parameters are Configurable only by administrator
user:
Antenna gain and cable loss.
Tx Power.
