7 Conclusion
The SpectraLink e340/h340/i640 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. SVP is proven to deliver enterprise-grade voice quality, battery life and call capacity
for SpectraLink handsets.
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.
