Wi-Fi Multimedia Traffic Management
Wi-Fi Multimedia (WMM) is a Wi-Fi Alliance specification based on the IEEE 802.11e
wireless Quality of Service (QoS) standard. WMM works with 802.11a, 802.11b, 802.11g,
and 802.11n physical layer standards.
WMM supports the following access categories (ACs):
● Voice
● Video
● Best effort
● Background
The following table shows the mapping of the WMM access categories to 802.1p priority
values. The 802.1p priority value is contained in a two-byte QoS control field in the WMM
data frame.

In a non-WMM or hybrid environment, where some clients are not WMM-capable, you can
configure an SSID with higher values for best effort and voice ACs, to allocate a higher
bandwidth to clients transmitting best effort and voice traffic.
