average backoff period. The period increases along with these two values.
Arbitration Inter Frame Spacing Number (AIFSN): Different from the fixed distributed
inter-frame spacing (DIFS) specified in the 802.11 protocol family, AIFSN varies across
ACs. A greater AIFSN indicates a longer backoff period.
Transmission Opportunity (TXOP): It specifies the maximum channel use duration after
successful channel contention. The duration increases along with this value. The value
0
indicates that a device can send only one packet through a channel after winning
contention for the channel.
AC_BE, AC_BK,
AC_VI, AC_VO
The WMM mechanism divides WLAN traffic by priority in descending order into the AC-VO
(voice stream), AC-VI (video stream), AC-BE (best effort), and AC-BK (background) access
categories. Packets in queues with higher priority have more opportunities to access
channels.
