Vocera Badge Overview
The communication badges allow a wearer instant communication with any other badge wearer as well a Private Branch Exchange (PBX) integration and badge location tracking. The utilization of an 802.11b/g wireless network requires the use of multicast and UDP unicast packet delivery with limited requirements for Quality of Service (QoS) as of Vocera Server Software release 3.1 (Build 1081). The encryption capabilities are 64/128 bit Wired Equivalent Privacy (WEP), Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC), and Cisco Temporal Key Integrity Protocol (CKIP) combined with the authentication capabilities of Open, Wi−Fi Protected Access−Pre−shared Key (WPA−PSK), WPA−Protected Extensible Authentication Protocol (PEAP) and Lightweight Extensible Authentication Protocol (LEAP).
With the push of a button, the Vocera server responds with Vocera, which is a prompt to issue commands such as record, where (am I) /is..., call, play, broadcast, messages, and so forth. The Vocera server provides the necessary services and/or call setup to complete the request.
Vocera's 802.11b capable Communication System makes use of proprietary voice compression and the use of a UDP port range. The Vocera System software runs on a Windows server that manages call set up, call connection and user profiles. They have partnered with Nuance 8.5 Speech Recognition and Voiceprint software in order to enable badge voice communications. Vocera recommends a separate Windows server to run the Vocera Telephony Solutions Software to enable Plain Old Telephone Service (POTS) connectivity with the badges.

The Vocera Solution
The Vocera Badge utilizes both unicast and multicast packet delivery to provide several key features that make up this complete solution. Here are four of the essential features that rely on proper packet delivery. Also provided is a basic understanding of how each feature uses the underlying network for delivery and functionality.
