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.
VLAN Support
The Airespace Wireless Enterprise Platform with the AireOS
operating system has the ability to manage different VLANs, each
with a unique SSID. Many times customers will choose to place voice
devices on a separate VLAN from data devices or they may choose to
segment their network based on security policies.
When VLANs are enabled, the Wireless Enterprise Platform uses
802.1Q tags on traffic entering onto the wired network. These tags
must be removed by a VLAN-capable switch before the packets reach
the SpectraLink 8000 Telephony Gateway or SpectraLink 8000 SVP
Server. On most switches, the switch port to which the SpectraLink
8000 Telephony Gateway or SpectraLink 8000 SVP Server is connected
must be configured as a non-trunked, or access port dedicated to the
voice VLAN. If the port is set to trunked, the SpectraLink 8000 System
equipment will not recognize the packet.
If you are using a switch that is not capable of removing these 802.1Q
tags, the SpectraLink Wireless Telephones must reside on the native
(or management) VLAN.
Notes on Configuration
The AP must support SpectraLink Voice Priority (SVP). Contact
your AP vendor if you need to upgrade the AP software.
