Figure 5-31 Station EDCA Parameters Queue： Displays the transmission queues: Data 0>Data 1>Data 2>Data 3. Arbitration InterFrame Space： A wait time for data frames. The wait time is measured in slots. Valid values for AIFS are 1 through 15. Minimum Contention An input to the algorithm that determines the initial random backoff wait Window： time (window) for retry of a transmission. Maximum Contention Window： The upper limit (in milliseconds) for the doubling of the random backoff value. TXOP Limit： The Transmission Opportunity (TXOP) is an interval of time, in milliseconds, when a WME client station has the right to initiate transmissions onto the wireless medium towards the EAP device. Valid values for TXOP Limit are from 0 to 8192 and should be exactly divided by 32. No Select Enable to specify that the EAP device should not acknowledge Acknowledgement： frames with QosNoAck as the service class value. By default, it is disabled. Unscheduled Automatic Power Save Delivery： Select Enable to enable APSD, which is a power management method. APSD is recommended if VoIP phones access the network through the EAP device. By default, it is enabled. 35

5.5.2
Station EDCA Parameters
Station EDCA parameters affect traffic flowing from the client station to the EAP device.
Figure 5-31 Station EDCA Parameters
Queue
：
Displays the transmission queues: Data 0>Data 1>Data 2>Data 3.
Arbitration Inter-
Frame Space
：
A wait time for data frames. The wait time is measured in slots. Valid
values for AIFS are 1 through 15.
Minimum Contention
Window
：
An input to the algorithm that determines the initial random backoff wait
time (window) for retry of a transmission.
Maximum
Contention
Window
：
The upper limit (in milliseconds) for the doubling of the random backoff
value.
TXOP Limit
：
The Transmission Opportunity (TXOP) is an interval of time, in
milliseconds, when a WME client station has the right to initiate
transmissions onto the wireless medium towards the EAP device. Valid
values for TXOP Limit are from 0 to 8192 and should be exactly divided
by 32.
No
Acknowledgement
：
Select
Enable
to specify that the EAP device should not acknowledge
frames with QosNoAck as the service class value. By default, it is disabled.
Unscheduled
Automatic Power
Save Delivery
：
Select
Enable
to enable APSD, which is a power management method.
APSD is recommended if VoIP phones access the network through the
EAP device. By default, it is enabled.
