Concept Guide

Parameter Description
An AP will only move to a
new channel if the new
channel has a lower
interference index value
than the current channel.
Free Channel Index
specifies the required
difference between the
two interference index
values before the AP
moves to the new channel.
The lower this value, the
more likely it is that the AP
will move to the new
channel.
Backoff Time
After an AP changes
channel or power settings,
it waits for this backoff
time interval before it asks
for a new channel/power
setting.
Error Rate Threshold
The minimum percentage
of PHY errors and MAC
errors in the channel that
will trigger a channel
change.
Error Rate Wait Time
Minimum time in seconds
the error rate on the AP
has to exceed its defined
error rate threshold
before it triggers a
channel change.
Noise Threshold
Maximum level of noise in
a channel that triggers a
channel change.
Noise Wait Time
Minimum time in seconds
the noise level has to
exceed the Noise
Threshold before it
triggers a channel change
on the AP.
Minimum Scan Time
Minimum number of times
a channel must be
scanned before it is
considered for
assignment. Best
practices are to configure
a Minimum Scan Time
between 1-20 scans.
