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, where the difference between Telepresence and the at this point in time prevalent Videoconferencing is defined as quality, simplicity, and reliability.
