Item Description
Dynamic
Channel Select
•
Close—Disables the DFS function.
•
Auto—With auto DFS enabled, an AC performs DFS for a radio when
certain trigger conditions are met on the channel, and returns the result to
the AP after a calibration interval (the default calibration interval is 8
minutes, which can be set through the Calibration Interval option). After
that, the AC will make DFS decisions at the calibration interval
automatically.
•
Manual—With one-time DFS configured for a radio, an AC performs DFS
for the radio when certain trigger conditions are met on the channel, and
returns the result to the AP after a calibration interval. After that, if you
want the AC to perform DFS for the radio, you have to make this
configuration again.
IMPORTANT:
If you select the manual mode, click Calibration on the Calibration page every
time you perform channel calibration.
CRC Error
Threshold
Set the CRC error threshold value, in percentage.
Channel
Interference
Threshold
Set the channel interference threshold value, in percentage.
Tolerance
Factor
A new channel is selected when either the configured CRC error threshold or
interference threshold is exceeded on the current channel. However, the new
channel is not applied until the quality of the current channel is worse than
that of the new channel by the tolerance threshold.
Spectrum
Management
•
Enable—Enable spectrum management.
•
Close—Disable spectrum management.
Power Setup
Note the following guidelines when configuring power adjustment:
•
If you lock the power first, and then enable power adjustment (by selecting Dynamic
Channel Select), power adjustment does not work because the power is locked. Therefore,
before enabling power adjustment, make sure that the power is not locked.
•
If you enable power adjustment and then lock the power, the last selected power is locked.
For how to lock the power, see "
."
Dynamic
Power Select
•
Close—Disables transmit power control (TPC).
•
Auto—With auto TPC enabled, the AC performs TPC for an AP upon
certain interference and returns the result to the AP after a calibration
interval (the default calibration interval is 8 minutes, which can be set
through the Calibration Interval option). After that, the AC makes TPC
decisions at the calibration interval automatically.
•
Manual—With one-time TPC configured, an AC performs TPC for the AP
upon certain interference, and returns the result to the AP after a
calibration interval (the default calibration interval is 8 minutes, which
can be set through the Calibration Interval option). After that, if you want
the AC to perform TPC for the AP, you have to make this configuration
again.
IMPORTANT:
If you select the manual mode, click Calibration on the Calibration page every
time you perform channel calibration.
