4-53
Max. Level=Minimum SNR Level + Delta from Minimum SNR Level.
Available values: 4 to 20 (dB) for units operating in the 5.2, 5.4 and 5.8
GHz bands. 11 to 20 (dB) for units operating in the 4.9 and 5.3 GHz
bands.
Default value: 4 (dB) for units operating in the 5.2, 5.4 and 5.8 GHz
bands. 11 (dB) for units operating in the 4.9 and 5.3 GHz bands.
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 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: 1 to 3600 seconds.
Default value: 30 seconds.
ATPC Power Level Step
The ATPC Power Level Step parameter defines the step size to be used
by the SUs for incrementing/decrementing the Current Transmit
Power after receiving a power-up/power-down message. If the distance
between the value of the Current Transmit Power and the desired
range is smaller than the step size, the power-up/power-down message
will include the specific step value required for this condition.
Valid range: 1-20 (dB)
Default value: 5 (dB)
ATPC Parameters in SU
ATPC Option
The ATPC Option enables or disables 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 Current Transmit Power determined by the
ATPC algorithm before it was disabled. It will change to the value
configured for the Initial Transmit Power parameter only after the next
reset or following loss of synchronization.
The default is Enable.
