VIDEO CONFERENCING. Video conferencing combines dedicated
audio, video, and communication networking technology
for real-time interaction. Companies use video conferencing to
reduce or eliminate travel while allowing employees to interact.
New applications such as Microsoft’s NetMeeting, offer
conference attendees at two (or more) locations real-time voice
and video conferencing. In addition, many video conferencing
applications include collaborative application sharing (for
shared presentations), multiperson document editing, background
file transfer, and a whiteboard (real-time shared interactive
displays) to draw and paste on. The projected lower cost
and high-bandwidth capability of next generation wireless systems
will allow more cost effective and portable video conferencing
services.

by Nokia. This video phone can both send and receive images
via high-speed wireless systems.
