Videoconferencing
Videoconferencing is a system allowing participants at different locations to view and hear each other immediately via video cameras and monitors along with microphones through telephone lines or the internet.
Marketing material for UMTS has emphasised the possibility of mobile videoconferencing, although whether there is actually a mass market for this service remains untested.
Today multi-user videoconferencing is now available and becoming more popular. Camfrog Webcam Chat (http://www.camfrog.com) and White Pine (http://www.wpine.com) both have software that allows you to host your own multi-user videoconference. With these new technologies it is possible to have group meetings with hundreds of users.
