a To change the maximum power level RF Auto-Tuning can assign to
the radio, select the power level from the Max. Transmit Power
pull-down list.
The default power level is default, which means RF Auto-Tuning can
assign up to the maximum power level allowed for the radio.
You can specify from 1 to 20.
b To change the minimum rate at which a radio is allowed to transmit
traffic to clients, select the rate from the Client Data Rate pull-down
list.
The radio automatically increases its transmit power when necessary
to maintain at least the minimum rate with an associated client.
The valid values depend on the radio type. All values are in Mbps.
„
For 802.11g radios— 54 , 48 , 36 , 24 , 18, 12 , 11 , 9 , 6 , 5.5 , 2 , or 1
„
For 802.11b radios— 11 , 5.5 , 2 , or 1
„
For 802.11a radios— 54 , 48 , 36 , 24 , 18 , 12 , 9 , or 6
The default minimum data transmit rate depends on the radio type:
„
The default minimum data rate for 802.11b/g and 802.11b radios
is 5.5 Mbps.
„
The default minimum data rate for 802.11a radios is 24 Mbps.
c To change the maximum percentage of client retransmissions a radio
can experience before RF Auto-Tuning considers changing the
channel on the radio, select the percentage from the Data
Retransmissions pull-down list.
A high percentage of retransmissions is a symptom of interference on
the channel.
You can specify from 1 to 100. The default is 10.
