Auto RF (RRM)
When using the Cisco Unified Wireless LAN Controller it is recommended to enable Auto RF to manage the channel and
transmit power settings.
Configure the access point transmit power level assignment method for either 5 or 2.4 GHz depending on which frequency band
is to be utilized.
If using automatic power level assignment, a maximum and minimum power level can be specified.
If using 5 GHz, it is recommended to enable up to 12 channels only to avoid any potential delay of access point discovery due
to having to scan many channels.
The 5 GHz channel width can be configured for 20 MHz or 40 MHz if using Cisco 802.11n Access Points.
