Video applications require a lot of memory
Lessons Learned
Training is necessary to ensure usage
Set up room and cameras ahead of time
Dont mix half and full duplex LAN
Number of multipoint conferences is usually
underestimated
Use static IP addresses
Switched 10 Mbps to the desktop is a minimum
Use of switches dedicated bandwidth makes the
project run more smoothly
16
It goes to every desktop, ISDN does not
IP Summary
IP networks will soon be real-time multimedia
capable
VOIP will help drive the corporate build out
Video will ride along for free
17
ATT is now the largest cable TV company in North
America
The Future
Bandwidth will be a commodity
Applications services will be where the money is
Public networks will replace private
Transition from ISDN to IP will occur over a 10
year span
18
Collaboration, streaming and remote presentations
will become dominant applications, with
videoconferencing included in the mix
The Future
Users need a business process that works better,
they dont need conferencing and collaboration
per se
Videoconferencing and collaboration tools need to
be integrated into the existing business processes
19
Travel will continue to be more costly and less
comfortable. Conferencing and collaborative
communications will be less costly and more
convenient.
Remember

God put us on earth to accomplish a certain
number of things. Those of us involved in
conferencing and collaborative communications are
so far behindthat we will live forever!
