Wi-Fi Array
Configuring the Wi-Fi Array 245
As an example, one SSID named accounting might require the highest level of
security, while another named guests might have low security requirements.
Another example may define an SSID named voice that supports voice over
Wireless LAN phones with the highest Quality of Service (QoS) definition. This
SSID might also forward traffic to specific VLANs on the wired network.

Understanding QoS Priority on the Wi-Fi Array
The Wi-Fi Array’s Quality of Service Priority feature (QoS) allows traffic to be
prioritized according to your requirements. For example, you typically assign the
highest priority to voice traffic, since this type of traffic requires delay to be under
10 ms. The Array has four separate queues for handling wireless traffic at
different priorities, and thus it supports four traffic classes (QoS levels).
