WHAT IS THE MAXIMUM AMOUNT OF USERS YOU WOULD RECOMMEND FOR MULTI USER VIDEO CONFERENCING?
Multi user video conferencing increases the download speed requirement stated above by a factor of N where N is the number of users in the conference. For eg. If a one on one conference would require 128 kbps, a 10 person video conference with all 10 transmit and receive would require 1.2 Mbps downlink and 128 kbps uplink.
