Common deployment: APs are loosely deployed. The transmit power of each radio is less than 50% of the maximum transmit power.
Centralized deployment: APs are densely deployed. The transmit power of each radio is less than 25% of the maximum transmit power.
Specifies the default region to which automatically discovered APs are added.

The radio type can be set to 802.11n, 802.11b/g/n, 802.11a/n, or 802.11ac.
You can bind a radio to a specified radio profile.

Unified static configuration of parameters

Radio parameters such as the channel and power of each radio are configured on the AC and then delivered to APs.

Dynamic management

APs can automatically select working channels and power when they go online.
In an AP region, APs automatically adjust working channels and power in the event of signal interference:
Partial calibration: The optimal working channel and power of a specified AP can be adjusted.
Global calibration: The optimal working channels and power of all the APs in a specified region can be adjusted.
When an AP is removed or goes offline, the AC increases the power of neighboring APs to compensate for the coverage hole.
Automatic selection and calibration of radio parameters in AP regions are supported.

Enhanced service capabilities

The AC supports 802.1a/b/g/n/ac. These modes can be used independently or jointly (a\n, b\g, b\g\n, and g\n).
