Wireless Access Point
User Guide
value 0 indicates that a device can send only one packet through a channel after
winning contention for the channel.
ACK Policies
WMM specifies the Normal ACK and No ACK policies.
− According to the No ACK policy, no ACK packet is used during wireless packet
transmission to acknowledge packet reception. This policy is applicable to scenarios
where interference is mild and can effectively improve transmission efficiency. In
case of strong interference, lost packets are not sent again if this policy is adopted.
This leads a higher packet loss rate and reduces the overall performance.
− According to the Normal ACK policy, each time a receiver receives a packet, it sends
back an ACK packet to acknowledge packet reception.
