Configuring EDCA Parameters
If you want to enable MAC optimization for voice, check the Enable Low Latency MAC check box.
Step 4
Otherwise, leave this check box unchecked, which is the default value. This feature enhances voice
performance by controlling packet retransmits and appropriately aging out voice packets on lightweight
access points, thereby improving the number of voice calls serviced per access point.
Note
We recommend that you not use the low latency MAC feature if you are using the 1140, 1250, 1260, and

3500 series access points that are based on the Marvell platform. If used, the data packets are retried at
the data rate specified multiple times without downshifting the rates.
We also recommend that you not use the low latency MAC feature if you are using the 1120, 1130, 1230,
and 1240 series access points (not based on the Marvell platform). If used, the number of retries is
reduced to 3 with the first retry at the initial rate.
