Spreading of Multimedia Services

• During the 90s, Internet became a public service
  with widespread consumer acceptance (More than 1
  million Internet subscribers in France).
• In addition to Text and Fixed Images, Internet
  provides audio and video. For example
• Real Audio
• CuSeeMee Video Conference

Conclusions

• Following the success of analog and digital
  mobile communication services, the next step is
  centered on
• High-speed Wireless Internet and Multi-media
  Services
• 3G networks are the support for this new
  generation of Mobile Services
