Manual Revision: 4.0
that the SU will increase/decrease the value of the Transmit
Power Control parameter by 2. Any value lower than 29 will
result in Step=1.
Available values: 1-100 (%)
Default value: 1
 ATPC Parameters in 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
range/speed trade-off), you may decide to limit the use of higher
rates. If the quality of the link is not good enough, it is
recommended to decrease the value of this parameter (the higher
the data rate, the higher the error rate). Otherwise, there is a high
probability that the unit will have to retransmit many frames several
times before temporarily reducing the data rate (see Number of
Retransmissions to Decrease Rate on page 2-82). A high number
of retransmissions reduces the overall throughput for the selected
SU as well as for all the other SUs served by the same AU. It is
