Cisco TelePresence, first introduced in October 2006, is a range of products developed by Cisco Systems designed to link two physically separated rooms so they resemble a single conference room, regardless of location.
Cisco documented the Telepresence concept and implementation details in the book Cisco TelePresence Fundamentals,[1] where the difference between Telepresence and Videoconferencing, prevalent at that point in time, is defined as quality, simplicity, and reliability.
