BreezeACCESS EZ AU-EZ 80 System Manual
4.2.6.2.3.2 Show Transmit Power Parameters
This option displays the Transmit Power parameter and the current transmit
power for the different modulation levels. Different power levels may be used for
different modulation levels by taking into account possible HW limitations or
regulatory restrictions.
4.2.6.2.4 ATPC Parameters
The Automatic Transmit Power Control (ATPC) algorithm simplifies the
installation process and ensures optimal performance while minimizing
interference to other units. This is achieved by automatically adjusting the power
level transmitted by each SU according to the actual level at which it is received
by the AU. To support proper operation of the system with optimal performance
and minimum interference between neighboring sectors, the ATPC algorithm
should be enabled in all units.
4.2.6.2.4.0.1 ATPC Option for EZ
The ATPC Option for EZ enables or disables the Automatic Transmit Power
Control (ATPC) algorithm for SU-EZ units. The ATPC feature requires Layer 3
connectivity.
The default is Disable.
4.2.6.2.4.0.2 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).
4.2.6.2.4.0.3 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).
Default value: 5 (dB) for units operating in the 5.4 and 5.8 GHz bands. 8 (dB) for
units operating in the 5.2 and 5.3 GHz bands.
4.2.6.2.4.0.4 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
