Vocera Communications said Tuesday that it has raised $12 million in its third round of funding, bringing the Cupertino, Calif.-based company's total funding to $20.1 million. 
The company makes software and hardware that provides an instant voice communication system for wireless LANs (local area networks) that run on 802.11b, or Wi-Fi, technology. Vocera's software runs on networking gear in buildings or campuses and enables voice communication between individuals who wear its badges. Vocera expects its product to ship this fall and is targeting hospitals, retail stores and other businesses with mobile workers that need to communicate.
