Quality of Service
Quality of Service (
QoS
) provides you with the ability to specify parameters on multiple queues for
increased throughput and better performance of differentiated wireless traffic like
Voice-over-IP
(VoIP);
other types of audio, video, and streaming media; and traditional IP data.
The following sections describe how to configure Quality of Service queues on the Professional Access

Understanding QoS
A primary factor that affects QoS is network congestion due to an increased number of clients attempting
to access the air waves and higher traffic volume competing for bandwidth during a busy time of day. The
most noticeable degradation in service on a busy, overloaded network will be evident in time-sensitive
applications like video,
Voice-over-IP
(VoIP), and streaming media.
Unlike typical data files, which are less affected by variability in QoS, video, VoIP and streaming media
must be sent in a specific order at a consistent rate and with minimum delay between
Packet
transmissions. If the quality of service is compromised, the audio or video will be distorted.
QoS and Load Balancing
By using a combination of load balancing (see “Load Balancing” on page 139) and QoS techniques, you
can provide a high quality of service for time-sensitive applications, even on a busy network. Load
balancing is a way of better distributing the traffic volume across access points. QoS is a means of
allocating bandwidth and network access based on transmission priorities for different types of wireless
traffic within a single access point.
802.11e and WMM Standards Support
QoS
describes a range of technologies for controlling data streams on shared network connections. The
