Parameter Meaning

WMM-EDCAParameters You don't usually need to change these settings. Using the default

settings is recommended.

Priority

The following priorities may be applied to individual transmission

packets:(Highest)8,(High)4,(Normal)2,and(Low)1.Fromthe

queue, these packets are processed in order of priority.

CWmin, CWmax

 Themaximumandminimumvalueofthecontentionwindow.

The contention window is used in the frame collision avoidance

structureperformedinIEEE802.11,andgenerallythesmallerthe

value in the window, the higher the probability that the queue

obtains the right to send.

AIFSN

 Theintervaltosendframes.TheunitoftheAIFSNisaslot,justas

thewindowdenedbyCWminandCWmaxis.Thesmallerthe

interval of sending frames, the faster the algorithm can restart. As

a result, the priority of the queue is higher.

TXOP Limit

The period of time that the queue can use after obtaining the

right to send. The unit is 32 ms. The longer this time, the more

frames can be sent per right to send. However, the que may

interferewithotherpackettransmissions.IfTXOPLimitissetto0

(zero), only one frame can be sent per right to send.

Admission Control

Restricts new frames from interfering with a previous queue. New

packets are prioritized lower until a queue of them is collected. As

the new queue accumulates more packets, its priority increases.
