WME – edit page contains the following parameters:

• Interface – Specify the interface for WMM.

• Comments – Optional comments for this entry.

• Active – Enable or disable WME.

• CWMIN – Minimum contention window. This parameter is input to the

algorithm that determines the initial random backoff wait time (window) for

retry of a transmission. The value specified here in the Minimum Contention

Window is the upper limit (in milliseconds) of a range from which the initial

random backoff wait time is determined.

• CWMAX – Maximum contention window. Maximum Contention Window.

The value specified here in the Maximum Contention Window is the upper

limit (in milliseconds) for the doubling of the random backoff value.

• AIFS – The Arbitration Inter-Frame Spacing Number specifies a wait time (in

milliseconds) for data frames.

• TX OP LIMIT – Transmission Opportunity is an interval of time when a WME

AP/station has the right to initiate transmissions onto the wireless medium

(WM). This value specifies (in milliseconds) the Transmission Opportunity

(TXOP); that is, the interval of time when the WMM AP/station as the right to

initiate transmissions on the wireless network.

• ACM – Enable or disable Admission Control

• NO ACK POLICY – Enable or disable No-acknowledgement

• Best Effort – AP side, low priority, high throughput. Bulk data that requires

maximum throughput and is not time-sensitive is sent to this queue.

• Video – AP side, high priority, minimum delay. Time-sensitive video data is

automatically sent to this queue.

• Voice – AP side, high priority. Time-sensitive data like VoIP and streaming

media are automatically sent to this queue.

• Best Effort (BSS) – Station side, low priority, high throughput. Bulk data that

requires maximum throughput and is not time-sensitive is sent to this queue.
