WMM shortens the Interframe Spacing requirements for high priority packets so that voice and video can be sent in bursts without the need to wait as much for lower priority data in between. Additionally, WMM is needed in order to obtain 802.11n and 802.11ac data rates. This means that with WMM disabled or for non-WMM clients, the maximum usable data rate is 54 Mbps.
