Quality of Service (QoS) on RP Radios
For more information about WMM and other QoS mechanisms, see “Traffic
Management (QoS)” on page 4-90 of Chapter 4: Wireless Local Area Networks
(WLANs). To learn how to customize RP WMM parameters, see “Viewing and
Customizing RP WMM Parameters” on page 4-104 on Chapter 4: Wireless
Local Area Networks (WLANs).
SpectraLink Voice Priority (SVP)
To raise voice quality over a wireless network, SpectraLink Corporation has
developed a de facto industry QoS mechanism called SpectraLink Voice
Priority (SVP). SVP is implemented in wireless phone handsets, wireless APs
or RPs, and SpectraLink servers. This IEEE 802.11-compliant mechanism
minimizes latency for voice traffic by establishing priority queues for voice
packets and by increasing the probability that all voice packets are transmitted
in a predictable and timely manner.
Any transmission delays can have an adverse effect on voice traffic. In addition
to priority queuing, SVP-enabled RPs and phone handsets transmit voice
packets in a coordinated fashion, using a zero backoff interval and thereby
eliminating delays introduced by random backoff intervals.
The RPs 210, 220, and 230 are all SVP compliant. You enable this feature in the
WLAN configuration. See Chapter 4: Wireless Local Area Networks (WLANs)
