  6. The Evolution of Mobile Communication

  7. Brief History of Mobile Communication Systems • 1979: AMPS is introduced in the USA • 1981: NMT is introduced in Scandinavia • 1982: CEPT creates Group Special Mobile (GSM) • 1986: Nine GSM technical proposals are presented • 1989: Digital AMPS (DAMPS) is standardized in USA • 1991: First GSM networks are launched • 1996: IS-95 CDMA is standardized in USA • 1997: 200 GSM networks, 109 countries, 44 million users • 1998: Five proposals for UMTS radio are presented • 1999: ITU-R releases IMT-2000 radio specifications Raul Bruzzone

  8. Spreading of Multimedia Services • During the 90’s, 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 Raul Bruzzone

  9. 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 Raul Bruzzone
