Introduction
This document provides design considerations and deployment guidelines for the implementation of the
Vocera® Badge Voice over WLAN (VoWLAN) technology on the Cisco Unified Wireless Network
infrastructure.
Note: Support for Vocera products should be obtained directly from Vocera support channels. Cisco
Technical Support is not trained to support Vocera−related issues.
This guide is a supplement to the Cisco Wireless LAN Controller Deployment Guide and only addresses the
configuration parameters that are particular to Vocera VoWLAN devices in a lightweight architecture. Refer
to Deploying Cisco 440X Series Wireless LAN Controllers for more information.
This document builds upon ideas and concepts presented in the Cisco IP Telephony Solution Reference
Network Design (SRND) and the Cisco Wireless LAN SRND. Both of these SRNDs are available online at
http://www.cisco.com/en/US/netsol/ns656/networking_solutions_program_home.html.
Prerequisites
