With the evolvement of the wireless networks, wireless clients that support both the 2.4 GHz and 5
GHz are more popular. However, by default, such dual-band wireless clients choose the 2.4 GHz to
connect, resulting in even worse congestion of the 2.4 GHz band and the waste of the 5 GHz band.
The prioritize 5 GHz function enables such dual-band wireless clients to connect the 5 GHz band on
network initialization if the 5 GHz signal strength the AP received reaches or exceeds the 5 GHz
threshold so as to improve the utilization of the 5 GHz band, reduce the load and interference on
the 2.4 GHz band, thus bettering user experience.
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.
