The prioritize 5 GHz function takes effect only on the condition that the wireless both of the 2.4 GHz and 
5 GHz are enabled, and the two bands share the same SSID, security mode and password. 
 
Air Interface Scheduling 
In mixed wireless rates environment, the traditional FIFO (First-in First-out) allocates more air 
interface time to clients with low transmission capacity and low spectrum efficiency, reducing the 
system throughput of each AP then the system utilization. 
The air interface scheduling function evenly allocates downlink transmission time to clients so that 
clients with high transmission rate could transmit more data, improving the throughput of each AP 
and number of clients allowed to be connected.
