Setting the Wireless Multimedia (WMM®) Access Mode to Background

The Wireless Multimedia (WMM®) is a feature in the bridge’s web-based setup page that is designed to prioritize packets depending on their respective access mode (traffic type).  One of these is the Background setting which prioritizes the packets for traffic and is not affected by increased latency, such as downloads and printing jobs.

NOTE:  WMM® settings should ONLY be configured by advanced users as incorrect settings can reduce wireless performance.

This article will provide instructions on how to configure the WMM® Access Mode to Background.  To know how, follow these steps:

Step 1:
Access the bridge's web-based setup page.  For instructions, click here.

Step 2:
Click Wireless > WMM®.

 

Step 3:
Select Background on the Access Mode drop-down menu.  Provide the rest of the settings on the screen.

 

The WMM® Background screen allows you to set the following information:

•   Use Aggregation - This option defines whether or not the Media Access Control (MAC) layer will set up an Add Block Acknowledgement (ADDBA) session.  The default value is No.  Select Yes to enable this option.

•   Accept Aggregation - This option defines whether or not the MAC layer will accept an ADDBA request.  The default value is Yes.  Select No to disable this option.

•   Max. Number of Packets in Aggregation - This option defines the maximum number of packets or sub-frames in the aggregate.  The range is 0 to 7.  The default value is 7.

•   Max. Aggregation Size - This option defines the maximum size of the aggregate in bytes.  The range is 0 to 16000.  The default value is 12000.

•   Timeout Internal - This option defines the timeout period in which the aggregate should be closed with a “closing condition” by the timer.  The range is 0 to 100 ms.  The default value is 3.

•   Min. Size of Packet in Aggregation - This option defines the minimum size of packets to be accumulated in the aggregate, by bytes.  The range is 0 to 1500.  The default value is 10.

•   ADDBA Timeout - This option defines the duration after which the ADDBA setup is terminated if there are no frame exchanges within this duration by the Block Acknowledgement (ACK) agreement.  The range is 0 to 65535 ms.  The default value is 0, which disables the timeout.

•   Aggregation Window Size - This option defines the maximum number of packets transmitted without getting ACKs.  The range is 0 to 64.  The default value is 64.

Step 4:
