Step 3
Choose one of the following options from the EDCA Profile drop-down list:
• WMM—Enables the Wi-Fi Multimedia (WMM) default parameters. This is the default value.
Choose this option when voice or video services are not deployed on your network.
• Spectralink Voice Priority—Enables SpectraLink voice priority parameters. Choose this option if
SpectraLink phones are deployed on your network to improve the quality of calls.
• Voice Optimized—Enables EDCA voice-optimized profile parameters. Choose this option when
voice services other than SpectraLink are deployed on your network.
• Voice & Video Optimized—Enables EDCA voice- and video-optimized profile parameters. Choose
this option when both voice and video services are deployed on your network.
Note If you deploy video services, admission control (ACM) must be disabled.
• Custom Voice—Enables custom voice EDCA parameters for 802.11a. The EDCA parameters under
this option also match the 6.0 WMM EDCA parameters when this profile is applied.
Step 4 If you want to enable MAC optimization for voice, select the Enable Low Latency MAC check box.
Otherwise, leave this check box unselected, which is the default value. This feature enhances voice
performance by controlling packet retransmits and appropriately aging out voice packets on lightweight
access points, which improves the number of voice calls serviced per access point.
Note We do not recommend you to enable low latency MAC. You should enable low latency MAC
only if the WLAN allows WMM clients. If WMM is enabled, then low latency MAC can be used
with any of the EDCA profiles. See the “Configuring QoS Enhanced BSS” section on page 7-39
for instructions on enabling WMM.

Step 6 To reenable the radio network, choose Network under 802.11a/n or 802.11b/g/n, select the 802.11a (or
802.11b/g) Network Status check box, and click Apply.
Step 7 Click Save Configuration to save your changes.
