Conclusion

The SpectraLink 8020/8030 Wireless Telephone uses Wi-Fi technology to deliver a full-featured mobile
extension to a call server or PBX. The purpose of this document is to outline the network design criteria
for a successful VoWLAN deployment. By applying the guidelines described in this document,
networking and telephony professionals can confidently design and deploy a Polycom Wi-Fi telephony
solution.
Some of the key takeaways include:

Voice and data applications have different attributes and network requirements. Several aspects
of the WLAN infrastructure, including coverage and capacity planning, require special
considerations for voice traffic.

Reliable QoS is a requirement for any enterprise voice application. Wireless VoIP is especially
vulnerable to many WLAN processes that can affect voice quality, including wireless traffic
contention and security authentication delays.

Selection of a security method for SpectraLink 8020/8030 handsets is a balance between the
degree of security required, the complexity of management and acceptable roam time
performance. Polycom offers a wide breadth of options along the WLAN security spectrum.

Several network design attributes need to be considered before deploying a VoWLAN solution,
including the use of subnets and complex network topologies that may affect the performance of
SpectraLink handsets.
Polycom‟s dedication and expertise helps ensure proper deployment for VoWLAN.
