Mobile video telephony
Today, the UMTS (WCDMA), and its Chinese equivalent, TD-SCDMA, enable a circuit-switched data connection of 64 kilobits per second. This connection is used for real-time video telephony over mobile networks, and is a popular service on UMTS networks in Japan, Korea, Taiwan, Europe, and many other countries and regions around the world. As operators are looking for additional services to leverage their networks and increase their income per subscriber, the addition of real-time video has become a real opportunity for growth. 3G handset manufacturers must include video telephony in their products. To do this they use the 3G-324M standard.
