Tx. Power Tuning Interval—Interval at which RF Auto-Tuning decides
whether to change the power level on radios. You can specify from 1
to 65535 seconds. The default is 300 seconds.
Power Ramp Interval—Interval at which power is increased or
decreased, in 1 dBm increments, on radios until the optimum power
level calculated by RF Auto-Tuning is reached. After each power ramp
interval, the radio increases or decreases the power by another 1 dB
until the radio reaches the power level selected by RF Auto-Tuning.
Channel Tuning Holddown—Minimum number of seconds a radio in a
radio profile must remain at its current channel assignment before
RF Auto-Tuning can change the channel.
The channel holddown provides additional stability to the network by
preventing the radio from changing channels too rapidly in response
to spurious RF anomalies such as short-duration channel interference.
You can specify from 0 to 65535 seconds. The default channel interval
is 900 seconds.
Tx. Power Backoff Timer—Interval at which radios reduce power after
temporarily increasing the power to maintain the minimum data rate
for an associated client.
At the end of each power-backoff interval, radios that temporarily
increased their power reduce it by 1 dBm. The power backoff
continues in 1 dBm increments after each interval until the power
returns to expected setting.
You can specify from 0 to 65535 seconds. The default is 10 seconds.
Service Profile Selection Tab
The Profile Selection tab lists the service profiles to which the radio profile
is mapped. The radios managed by the radio profile provide wireless
service for the service profiles' SSIDs.
To map the radio profile to a service profile, select the service profile in
the Available Service Profiles list. Click Add to move the profile name to
the Current Service Profiles list.
To remove the mapping between the radio profile and a service profile,
select the service profile in the Current Service Profiles list. Click Remove
to move the profile name to the Available Service Profiles list.
