Known Limitations
Voice quality may be impaired in an environment with heavy
wireless TCP traffic, such as FTP data transfers.
Access Point Capacity and Positioning
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.

Configuration Settings
Xirrus Arrays initially boot with all radios disabled except for the
monitor radio. The monitor radio may be left enabled and in no way
interferes with the SpectraLink Wireless Telephones; however it was
disabled for the certification process for simplicity.
Disabling the monitor radio
If you wish to disable the monitor radio, use the following CLI
commands:
Xirrus_WLAN_Array# configure
Xirrus_WLAN_Array(config)# interface iap
Xirrus_WLAN_Array(config-iap)# abg2 down
Xirrus_WLAN_Array(config-iap)# show

Setting Radio Channels
With the SpectraLink Wireless Telephones operating in 802.11b mode,
at least one of the Wireless LAN Array’s Integrated Access Points
(IAPs) must be set to the 2.4 GHz band. Any of the Array’s four abg
radios may be used, and up to three may be used simultaneously.
However, the radios must be set to the non-overlapping channels 1, 6,
and 11. This may be done using the following CLI commands:
Xirrus_WLAN_Array# configure
Xirrus_WLAN_Array(config)# interface iap
Xirrus_WLAN_Array(config-iap)# abg1 channel 11
Xirrus_WLAN_Array(config-iap)# abg3 channel 1
Xirrus_WLAN_Array(config-iap)# abg4 channel 6

Configuring an SSID
An SSID for the phones must be set on the Array. The following CLI
commands show how to implement an SSID called ‘spec’.
Xirrus_WLAN_Array(config)# ssid
Xirrus_WLAN_Array(config-ssid)# add spec
Xirrus_WLAN_Array(config-ssid-spec)# broadcast on
Xirrus_WLAN_Array(config-ssid-spec)# show
