Channel and Power
The Channel and Power screen in the Smart RF Policy includes the following configuration sections:
• Power Settings – Determine the minimum and maximum transmit power values assigned to Smart
RF managed radios.
• Channel Settings – Determine the pool of channels and channel widths assigned to the Smart RF
managed radios.
Figure 7: Channel and Power tab
The Power Settings parameters determines the minimum and maximum power values (in dBm) that
can be assigned to Smart RF managed radios. By default, each radio is 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.
Note
The power specified here is per chain.
As a general best practice, do not increase the Maximum Power values for the 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 the transmit power if a neighboring AP fails or
a coverage hole is detected.
Note
Only increase the Maximum Power values if the Neighbor Recovery and Coverage Hole
Recovery features are disabled.
The Channel Settings parameters define the pool of channels that can be assigned to the Smart RF-
managed radios in addition to the channel width (20 MHz, 40 MHz, 80 MHz, or 160 MHz). By default, the
