AirTime  Fairness  (ATF)

Designed to function as wireless QoS, this feature regulates the downlink 
air-time needed to transmit frames instead of egress bandwidth. The 
feature allocates air-time autonomously based on the policies 
implemented. This brings in fairness of time allocated across multiple 
operators in large deployments.
