6.2.3.1 WLAN QoS Deployment Considerations

Before defining a WLAN QoS configuration, refer to the following deployment guidelines to ensure the
configuration is optimally effective:
• WLAN QoS configurations differ significantly from QoS policies configured for associated access point
radios. WLAN QoS configurations are designed to support the data requirements of wireless clients,
including the data types they support and their wireless network permissions. Radio QoS policies are
specific to the transmit and receive characteristics of the connected radio's themselves, independent
from the wireless clients these access point radios support.
• Enabling WMM support on a WLAN only advertises WMM capability to wireless clients. The wireless
clients must be also able to support WMM and use the parameters correctly while accessing the
wireless network to truly benefit.
• Rate limiting is disabled by default on all WLANs. To enable rate limiting, a threshold must be defined
for WLAN.
• Before enabling rate limiting on a WLAN, a baseline for each traffic type should be performed. Once a
baseline has been determined, a minimum 10% margin should be added to allow for traffic bursts.
• The bandwidth required for real-time applications such as voice and video are very fairly easy to calculate
as the bandwidth requirements are consistent and can be realistically trended over time. Applications
such as Web, database and email are harder to estimate, since bandwidth usage varies depending on
how the applications are utilized.
