Airtime Fairness Mode
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.
Airtime Fairness Modes
Navigate to RF which is at the top right corner of the Instant UI and click ARM.
The Airtime 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 limits are not enforced
 Fair Access— Allocates Airtime evenly across all the clients
 Preferred Access— 11n clients get more airtime than 11a/11g, which get more airtime than 11b. The ratio is
16:4:1.
