61
Summary
  • By 2010, major revenues of 3G services are coming
    from 6 categories of 3G enabled data services and
    simple voice service
  • WCDMA and cdma2000 technologies will dominate the
    3G market
  • 3G Evolution
  • UMTS network (RAN and CN) is evolving towards
    ALL-IP network to converge voice and data
    services
  • Heterogeneous network integration of WLAN and
    GPRS/3G
  • Key issues for 3G
  • Mobile terminals (display, battery, multimedia
    support)?
  • Killer applications?
