
AIFS
：
The Arbitration Inter-Frame Spacing Number specifies a wait time (in
milliseconds) for data frames
。

TxOP Limit
：
Transmission Opportunity is an interval of time when a WME AP has the
right to initiate transmissions onto the wireless medium (WM). This value specifies (in
milliseconds) the Transmission Opportunity (TXOP) for AP; that is, the interval of time
when the WMM AP has the right to initiate transmissions on the wireless network.


ACM bit
：
Admission Control Mandatory, ACM only takes effect on AC_VI and AC_VO.
When you do not click Checkbox, it means that the ACM is controlled by the
connecting AP. If you click Checkbox, it means that the Client is in charge
。

No ACK policy bit
：
Acknowledgment Policy, WMM defines two ACK policies: Normal
ACK and No ACK. Click “Checkbox” indicates “No ACK”
When the no acknowledgement (No ACK) policy is used, the recipient does not
acknowledge received packets during wireless packet exchange. This policy is suitable in
the environment where communication quality is fine and interference is weak. While the
No ACK policy helps improve transmission efficiency, it can cause increased packet loss
when communication quality deteriorates. This is because when this policy is used, a
sender does not retransmit packets that have not been received by the recipient.
When the Normal ACK policy is used, the recipient acknowledges each received uncast
packet.
