Wi-Fi Multimedia (WMM) refers to a Wi-Fi Alliance interoperability certification,
based on the IEEE 802.11e standard. It provides basic QoS features to IEEE 802.11 networks.
WMM prioritizes traffic according to four Access Categories (ACs): voice (AC_VO), video (AC_VI), best effort (AC_BE), and background (AC_BK).
This includes configuring Enhanced Distributed Channel Access (EDCA) parameters for each AC of AP and Station (STA),
mapping between WMM ACs and Differentiated Services Codepoint (DSCP) tags.
