Specifies a label for the common set of EDCA parameters that are used by a QoS Station/AP
to contend for the channel in order to transmit MSDUs with certain priorities.Available
access categories are:
– Background
– Best Effort
– Video
– Voice
Tabulated below are the default EDCA parameters for the wireless client (Station) and AP
device, specific to each access category.

'Access Category' is a read-only parameter and cannot be configured.
Specifies the minimum value for Contention Window (CW) for the wireless QoS EDCA
profile. To configure, enter the CW Min in the range of 0 to 32767, for both wireless client
and AP device.
Specifies the maximum value for Contention Window (CW) for the wireless QoS EDCA
profile. To configure, enter the CW Max in the range of 0 to 32767, for both wireless client
and AP device.
Specifies the Arbitration Inter-Frame Space Number (AI FSN) per access category. To
configure, enter the AI FSN in the range of 2 to 15 for Station and 1 to 15 for AP.
The Transmission Opportunity Limit (TxOP) is a time interval for the QoS enhanced client to
initiate a frame exchange on the wireless medium. The TxOP Limit defines the upper limit
based on the TxOP value a wireless entity can obtain for a particular access category.
To configure, enter the TxOP in the range of 0 to 8160, for both Station and AP device.
The Admission Control Mandatory (ACM) defines, if an AP device accepts or rejects a request
traffic stream with certain QoS specifications, based on available channel capacity and link
conditions.
To configure ACM for each access category, select either Enable or Disable from the drop
down menu
