CW Min: 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 Station and AP.
•
CW Max: 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 Station and AP.
•
AI FSN: 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.
•
TxOP: The Transmission Opportunity Limit (TxOP) is an interval during which a particular QoS enhanced client has
the right 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.
•
ACM: The Admission Control Mandatory (ACM) defines if an AP 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.
