2 Paradigm shift from 1st generation towards beyond 3G First Generation Analogue Circuit switched Basic voice telephony Low capacity Limited local and regional coverage Second Generation Digital Circuit switched Voice plus basic data applications Low data speed Enhancements towards packet switching higher data rates Trans-national and global roaming Third Generation Digital Packet and circuit switched Advanced data (multimedia) applications Fast data access Global coverage Global roaming Beyond Third Generation Digital Packet switched All IP based (IPv6) More advanced multimedia applications User in control Flexible platform of complementary access systems High speed data Improved QoS Global coverage Global roaming Wireless data already be introduced in second generation mobile Euro-China Event 2002 Page 3 Siemens, 2002 Evolution of mobile communication systems 1980s 1990s 2000s 2010s 1G 1G+ 2G 2G+ 3G 3G+ Beyond 3G+ Beyond 3G full commercial deployment trials Analog Digital Wideband Digital??? European research on 3G started in 1989 within the RACE I program and 1991 in RACE II European research on 3G continued in 1995 within the ACTS program European research on systems beyond 3G started in 1999 within the IST program standardisation research Framework Program 6 on future systems Euro-China Event 2002 Page 4 Siemens, 2002 ICM templ-1-o-example.ppt 2
