This chapter will discuss these features at a high level; to learn how to
configure them, see Chapter 3: Wireless Local Area Networks (WLANs).
SVP. SVP maintains a high QoS in the wireless network, specifically for
VoWLAN devices that are SVP-capable. SVP is implemented in wireless phone
handsets, wireless APs, and SpectraLink servers. This IEEE 802.11-compliant
mechanism minimizes latency for voice traffic by providing priority queues
reserved for voice packets and by increasing the probability that all voice
packets are transmitted in a predictable and timely manner.
If your network includes a SpectraLink server and SVP-capable phones, you
should enable SVP in the WLAN that includes these phones. RPs then recog-
nize SVP-encapsulated frames and handle them accordingly.
WMM. WMM is a more comprehensive QoS solution because it can provide
differentiated handling for any type of traffic based on its priority. Like 802.1p
and Differentiated Services (DiffServ) in Ethernet networks, WMM divides
traffic into multiple priority queues and then assigns different settings to each
queue. Although the types of settings dictated by the protocols are of course
