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 defined 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 queue 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.
