Item Description
Max Neighbor
Count Specify the maximum number of neighbors, which are managed by the same
AC.
Power
Constraint
Set the power constraint for all 802.11a radios. After power constraint is set,
the transmission power of a client is the current transmission power minus the
configured power constraint value.
IMPORTANT:
Enable spectrum management before configuring the power constraint;
otherwise, the configuration does not take effect.
Configuring a radio group
With DFS or TPC configured for a radio, the AC calculates the channel quality or power of the radio at
the calibration interval. When the result meets a trigger condition, the AC selects a new channel or
power for the radio. In an environment where interference is serious, frequent channel or power
adjustments may affect user access to the WLAN network. In this case, you can configure a radio group
to keep the channel or power of radios in the group unchanged within a specified time. The channel and
power of radios not in the radio group are adjusted normally.
After a channel or power adjustment (one-time, auto, or initial DFS or TPC), the channel or power of any
radio in the radio group keeps unchanged within the specified holddown time. When the holddown time
expires, the AC calculates the channel or power again. If the result meets a trigger condition, the channel
or power is changed, and the new channel or power keeps unchanged within the specified holddown
time. This mechanism continues.
NOTE:
Before entering the Radio Group page, configure channel or power adjustment on the Parameters tab.
1. Select Radio > Calibration from the navigation tree.
2. Click Radio Group.
3. Click Add.
The Radio Group page appears.
