1 Enhanced Multimedia User Experience beyond 3G Minoru Etoh Research Laboratories NTT DoCoMo September 10 th, 2007 Union

2 Presentation Summary New generation networks always foster new killer application environments. examples: 2.5G: mobile web-browsing and ,aka i-mode 3G: flat-rate services: video clip download, MMS 3.5G: music content delivery mobile SNS, 3D games Beyond 3G potentials: high capacity & low latency -> broadband content delivery interactive games and HiFi media (e.g., VoIP)+ mobile specific applications (e.g., Context-aware services) Union 2

3 Cellular Generation Global Outlook GSM is dominating 80% of cellular system in the world Japan s 3G penetration ratio is more than 70%. Global Celluar System Share CDMA2000 1x 10.9% CDMA 2.5% W-CDMA 2.7% PDC 1.8% others 3.0% 2 billion user Cellar System Share in Japan CDMA2000 1x 27.6% 97million users PDC 27.1% cdmaone 0.6% GSM 79.0% W-CDMA 44.7% 2G v.s. 3G 2G(86.3%) GSM Association as of Mar G 13.6% 2G(27.7%) 2G v.s. 3G 3G(72.3%) TCA as of mar Union 3
