The minimum value for the Maximum Tx Power is -10 dBm. The
maximum value depends on several unit properties and parameters:
! The HW revision of the unit
! The modulation level
! The Maximum Allowed Tx Power as defined for the applicable Sub
Band.
! The Maximum EIRP as defined for the applicable Sub Band,
together with the value of the Antenna Gain. In certain countries the
Maximum EIRP of some equipment types cannot exceed a certain
value. In these cases the Transmit Power cannot exceed the value of
(Maximum EIRP – Antenna Gain).
For information on how to view the Sub Bands supported by the unit
and the supported parameters’ values and options, refer to Show
Country Dependent Parameters on page 4-9.
The unit calculates the maximum allowed Maximum Tx Power
according to the unit properties and parameters listed above, and
displays the allowed range when the Maximum Tx Power parameter is
selected.
The default Maximum Tx Power is the highest allowed value.
ATPC Parameters in AU
ATPC Option
The ATPC Option enables or disables the Automatic Transmit Power
Control (ATPC) algorithm.
The default is Enable.
ATPC Minimum SNR Level
The Minimum SNR Level defines the lowest SNR at which you want
each SU to be received at the AU (the lower limit of the optimal
reception level range).
Available values: 4 to 60 (dB).
Default value: 28 (dB).
ATPC Delta from Minimum SNR Level
The Delta from Minimum SNR Level is used to define the highest SNR at
which you want each SU to be received at the AU (the higher limit of the
optimal reception level range):
