Teleconference using a video link. Simply due to costs, teleconferences are frequently limited to audio links (telephone or computer-based).

A teleconference or teleseminar is the live exchange and mass articulation of information among several persons and machines remote from one another but linked by a telecommunications system. Terms such as audio conferencing, telephone conferencing and phone conferencing are also sometimes used to refer to teleconferencing.

The telecommunications system may support the teleconference by providing one or more of the following audio, video, and/or data services by one or more means, such as telephone, computer, telegraph, teletype, radio, and television.^[1]

[edit] Internet teleconferencing

Internet teleconferencing includes internet telephone conferencing, videoconferencing, and Augmented Reality conferencing.

Internet telephony involves conducting a teleconference over the Internet or a Wide Area Network. One key technology in this area is Voice over Internet Protocol (VOIP). Popular software for personal use includes Skype, Google Talk, Windows Live Messenger and Yahoo Messenger.

A working example of a Augmented Reality conferencing was demonstrated at the Salone di Mobile in Milano by AR+RFID Lab. ^[2] TELEPORT is another AR teleconferencing tool.^[3]
