ATC + WMM
When used in conjunction, WMM (WiFi MultiMedia) and ATC (Automatic Traffic Classifier) ensure that all packets emanating from a wireless access point are assigned a priority on the network. WMM priorities are retained on packets where they are already set, and non-prioritized packets are assigned an ATC value which is mapped to a WMM priority.
