The Vocera Communications System enables instant voice-activated communication among people within a building or campus like setting.

This wearable wireless 802.11b device recognizes spoken names, job functions, groups locations. It has call-blocking, call-screening 'do not disturb' modes, well as conference calling group messaging functions.

Vocera Communications System uses Elmic System's networking protocols, which help facilitate and manage connections between access points. Specifically, Elmic's Turbo Treck DHCP automatically configures in real-time the IP addresses of the Vocera devices, while Elmic's Turbo Treck TCP/IP protocol is responsible for moving and verifying correct delivery of Vocera data.
