Question
Why are the APs regularly exceeding the configured power threshold for the Smart-RF policy?
Environment
•All WiNG Controllers
•All WiNG Access Points
•WiNG v5.X Software
Answer
The Power Settings parameters determines the minimum and maximum power values (in dBm) that can be assigned to 2.4 GHz and 5 GHz Smart RF managed radios. By default each 2.4 GHz and 5 GHz will be assigned a transmit power value between 4 - 17 dBm which can be configured by modifying the Minimum Power and Maximum Power parameters for each radio type.

As a general best practice recommendation it is not recommended that you increase the Maximum Power values for the 2.4 GHz or 5 GHz radios beyond the default 17 dBm value. The default value has been defined to provide a 3 dBm margin for the Neighbor Recovery and Coverage Hole Recovery features. If each radio in the system is operating at a maximum of 20 dBm, the Smart RF managed radios will be unable to increase their transmit power if a neighboring AP fails or a coverage hole is detected. You should only increase the Maximum Power values if the Neighbor Recovery and Coverage Hole Recovery features are disabled.
