BreezeACCESS 4900 122 System Manual
For information on how to view the Sub-Bands supported by the unit and the
supported parameters' values and options, refer to section “Show Country
Dependent Parameters” on page 72.
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.
For each modulation level, the unit will use as maximum transmit power the
minimum between this parameter and the maximum Tx power allowed by the HW
and the Country Code for the specific modulation level.
The default Maximum Tx Power is the highest allowed value.
4.2.6.2.7.2.2 Show Maximum Tx Power Parameters
This option displays the Maximum Tx Power parameter and the current maximum
Tx power for the different modulation levels.
4.2.6.2.7.3 ATPC Parameters in AU
4.2.6.2.7.3.1 ATPC Option
The ATPC Option enables or disables the Automatic Transmit Power Control
(ATPC) algorithm.
The default is Enable.
4.2.6.2.7.3.2 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).
4.2.6.2.7.3.3 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):
Max. Level=Minimum SNR Level + Delta from Minimum SNR Level.
Available values: 4 to 20 (dB).
4.2.6.2.7.3.4 Minimum Interval Between ATPC Messages
The Minimum Interval Between ATPC Messages parameter sets the minimal time
between consecutive power-up/power-down messages to a specific SU. Setting a
low value for this parameter may lead to higher overhead and to an excessive rate
of power level changes at the SUs. High values for this parameter increase the
time it will take the SUs to reach optimal transmit power level.
