About WMM

WMM Access Categories

At present, WMM defines traffic into 4 access categories.

AC_VO: Voice (highest priority)

AC_VI: Video (high priority)

AC_BE: Best effort (medium priority)

AC_BK: Background (low priority)

802.11 uses DCF (Distributed Coordination Function) scheme of the CSMA/CA

(Carrier Sense Multiple Access / Collision Avoidance) protocol to reduce the chances

of packets collision while one more devices access the wireless media at the same

time. A client wishing to transmit has to first listen to the channel for a predetermined

amount of time so as to check for any activity on the channel. If the channel is sensed

"idle" then the client is permitted to transmit. If the channel is sensed as "busy" the

station has to defer its transmission. The random interval provides a fair transmission

chance for all the devices.
