BreezeACCESS Version 4.5 System Manual
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 16. Therefore, if
ATPC Power Level Step is 14, than
Step=2 [ATPC Step*(No. of Levels-1)/100= 14*15/100=2.1],
meaning that the SU will increase/decrease the value of the
Transmit Power Control parameter by 2. Any value lower than
14 will result in Step=1.
Available values: 1-100 (%)
Default value: 1
! ATPC Parameters in IF Based SU
" ATPC Option: To enable or disable the Automatic Transmit
Power Control (ATPC) algorithm. The parameter takes effect
immediately. However, when changed from Enable to Disable,
the transmit power level shall remain at the last level
determined by the ATPC algorithm before it was disabled. It will
change to the value configured for the Transmit Power Control
parameter only after the next reset.
The default is Enable.
" ATPC Maximum Last Level Time After Reset: The maximum
time (in seconds) of attempting to associate with an AU after
reset, using the last value of the Current Transmit Power
Control. If this time had elapsed without succeeding to
associate with the AU, the unit will use the configured value of
the Transmit Power Control parameter .
Available values: 0-3600 (seconds)
Default value: 30 (seconds)
" ATPC Maximum Last Level Time After Synchronization
Loss: The maximum time (in seconds) of attempting to associate
with an AU after losing synchronization, using the last value of
the Current Transmit Power Control. If this time had elapsed
without succeeding to associate with the AU, the unit will use
the configured value of the Transmit Power Control parameter.
Available values: 0-3600 (seconds)
Default value: 120 (seconds)
Other Air Interface Parameters
! Maximum Data Rate – Displays the current maximum data rate,
and allows entry of a new value for the maximum data rate.
BreezeACCESS units operate at data rates of 3 Mbps, 2 Mbps, and
1 Mbps. Under certain conditions (compatibility reasons or
