Figure 33 WMM configuration
This page allows you to configure WiFi Multi-Media (WMM). WMM is an
implementation of Quality of Service (Qos) which is defined by the IEEE standard
802.11e.
WMM Support:
Sets WMM support. Choices are Auto, On, or Off. If enabled (Auto or On), the WME
Information Element is included in beacon frame.
No-Acknowledgement:
Sets No-Acknowledgement support. Choices are On or Off. When enabled,
acknowledgments for data are not transmitted.
Power Save Support:
Sets Power Save support. Choices are On or Off. When Power Save is enabled, the
AP queues packets for STAs that are in power-save mode. Queued packets are
transmitted when the STA notifies AP that it has left power-save mode.
EDCA AP Parameters:
Specifies the transmit parameters for traffic transmitted from the AP to the STA for the
four Access Categories: Best Effort (AC_BE), Background (AC_BK), Video (AC_VI),
and Voice (AC_VO). Transmit parameters include Contention Window (CWmin and
CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and Transmit Opportunity
Limit (TXOP Limit).
There are also two AP-specific settings: Admission Control and Discard Oldest First.
Admission control specifies if admission control is enforced for the Access Categories.
Discard Oldest First specifies the discard policy for the queues. On discards the
oldest first; Off discards the newest first.
EDCA STA Parameters:
Specifies the transmit parameters for traffic transmitted from the STA to the AP for the
four Access Categories: Best Effort (AC_BE), Background (AC_BK), Video (AC_VI),
and Voice (AC_VO). Transmit parameters include Contention Window (CWmin and
CWmax), Arbitration Inter Frame Spacing Number (AIFSN), and Transmit Opportunity
Limit (TXOP Limit).
