Radio QoS Configuration and Deployment Considerations
Radio QoS Policy
Before defining a radio QoS policy, refer to the following deployment guidelines to ensure the configuration is optimally
effective:
• To support QoS, each multimedia application, wireless client and WLAN is required to support WMM.
• WMM enabled clients can co-exist with non-WMM clients on the same WLAN. Non-WMM clients are always assigned a
best effort access category.
• Motorola Solutions recommends default WMM values be used for all deployments. Changing these values can lead to
unexpected traffic blockages, and the blockages might be difficult to diagnose.
• Overloading an access point radio with too much high priority traffic (especially voice) degrades the overall service quality
for all users.
• TSPEC admission control is only available with newer voice over WLAN phones. Many legacy voice devices do not support
TPSEC or even support WMM traffic prioritization.
