Please refer to the Polycom Deploying Enterprise-Grade Wi-Fi Telephony
white paper. This document covers the security, coverage, capacity
and QoS considerations necessary for ensuring excellent voice quality
with enterprise Wi-Fi networks.
For more detailed information on wireless LAN layout, network
infrastructure, QoS, security and subnets, please see the Best Practices
Guide for Deploying SpectraLink 8020/8030 Wireless Telephones. This
document identifies issues and solutions based on Polycom’s
extensive experience in enterprise-class Wi-Fi telephony, and
provides recommendations for ensuring that a network environment
is adequately optimized for use with SpectraLink 8020/8030 Wireless
Telephones.
For setting up the data rates, please consult your facility’s RF site
survey, designed for voice traffic, to determine if you have sufficient
coverage to support all data rates. SpectraLink Wireless Telephones
require the following minimum dBm reading to support the
corresponding “Required” data rate setting in the access point.
802.11

All SpectraLink Wireless Telephones on the WLAN network must be

802.11g). Handsets configured for different radio standards will not
work together.
