2 clients @ 6Mbps get media access of 3Mbps each = 6Mbps total
Client1 @ 300Mbps + Client2 @ 6Mbps get media access of
5.88Mbps each = 11.76Mbps total
Airtime fairness
Each WLAN participant gets equal time access.
WLAN clients will show throughput proportional to the PHY rate.
Provides better overall throughput.
Example of airtime fairness:
Client1 @ 300Mbps + Client2 @ 6Mbps get media access or
150Mbps for Client1 + 3Mbps for Client 2 = 153Mbps total
With FCA the user can adjust the client access policy in multiple steps between
packet fairness and airtime fairness.
FCA can be enabled or disabled for any given WLAN Service in its QoS Settings
tab. The level at which it is applied (between 100% Airtime Fairness and 100%
Packet Fairness) is a global parameter that is set under VNS Configuration ->
Global -> Wireless QoS.
