◆

WMM defines four access categories (ACs) – voice, video, best effort, 

and background. These categories correspond to traffic priority levels 

and are mapped to IEEE 802.1D priority tags (see Table 6-1). The 

direct mapping of the four ACs to 802.1D priorities is specifically 

intended to facilitate interpretability with other wired network QoS 

policies. While the four ACs are specified for specific types of traffic, 

WMM allows the priority levels to be configured to match any network-

wide QoS policy. WMM also specifies a protocol that access points can 

use to communicate the configured traffic priority levels to QoS-

enabled wireless clients.

◆

Although turning off the requirement for the sender to wait for an 

acknowledgement can increases data throughput, it can also result in a 

high number of errors when traffic levels are heavy.
