BreezeACCESS Version 4.3 System Manual
 ATPC Option: To enable or disable the Automatic Transmit
Power Control (ATPC) algorithm.
The default is Disable.
 Minimum RSSI Level: Enables you to define the lowest level at
which you want each SU to be received at the AU (the lower limit
of the optimal reception level range).
Available values: -100 to 0dBm.
Default value: -74 dBm for products operating in the 5.7 GHz
band, and -79 dBm for products operating in the 5.2 GHz band
 Maximum RSSI Level: Enables you to define the highest level
at which you want each SU to be received at the AU (the higher
limit of the optimal reception level range).
Available values: -100 to 0 dBm.
Default value: -64 dBm for products operating in the 5.7 GHz
band, and -69 dBm for products operating in the 5.2 GHz band.
 RSSI Memory Factor: Enable you to define the parameter that
determines the weight of history (value of last calculated average
RSSI) in the formula used for calculating the average RSSI. The
higher the value of this parameter, the higher is the weight of
history in the formula.
Available values: -1 to 32. -1 is for no weight for history,
meaning that average RSSI equals the last measured RSSI.
Default value: 5
 Minimum Interval Between ATPC Messages: To set the
minimal time between consecutive power-up/power-down
messages to a specific SU. Setting a low value for this parameter
may lead to a higher overhead and an excessive rate of power
level changes at the SUs. High values for this parameter
increase the time it will take until the SUs reach optimal
transmit power level.
Available values: 0 to 3600 seconds.
Default value: 120 seconds.
 ATPC Power Level Step - The step size in percentages of
maximum number of available levels that the SU will use when
receiving an ATPC Power-Up/Power-Down message. The formula
for calculating the step size is:
Step=max{1, [ATPC Step*(No. of Levels-1)/100]} (rounded down).
In SU-A/E the number of available levels is 8. Therefore, if ATPC
Power Level Step is 29, than Step=2 [29*7/100=2.03], meaning
NOTE:
The value of the Maximum RRSI Level must be higher than the value of the
Minimum RRSI Level. The system will not accept a Maximum RRSI Level value
that is lower than the current Minimum RRSI Level value, and vice versa.
