Air Time Fairness
This feature provides equal access to all clients on the wireless medium, regardless of client type, capability, or
operating system, thus delivering uniform performance to all clients. This feature prevents some clients from
monopolizing resources at the expense of other clients.
Air Time Fairness Modes
The Air Time Fairness consists of the following modes:
 Default Access - Provides access based on the client request. When Air Time Fairness is set to default access,
per user and per SSID bandwidth contracts are not enforced
 Fair Access - Allocates Airtime evenly across all the clients
 Preferred Access - Allocates Airtime to all the clients but preference is for higher performing clients

Customize valid channels
You can customize the valid 5GHz channels and the valid 2.4 GHz channels for the IAP.
Min transmit power
Minimum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments. You may also specify
a special value of 127 dBm for regulatory maximum to disable power adjustments for environments such as
outdoor mesh links. Higher power level settings may be constrained by local regulatory requirements and AP
capabilities. In the event that an AP is configured for a Min Tx EIRP setting it cannot support, this value will be
reduced to the highest supported power setting.
Default: 18 dBm
Max transmit power
Maximum effective isotropic radiated power (EIRP) from 3 to 33 dBm in 3 dBm increments. Higher power level
settings may be constrained by local regulatory requirements and AP capabilities. In the event that an AP is
configured for a Max Tx EIRP setting it cannot support, this value will be reduced to the highest supported power
setting.
