2 Contents! Emergence of 3G Mobile! What is 3G Mobile?! 3G Services! 3G System & Terminals! Current Issues 2

3 Emergence of 3G Mobile Users Rapid increase of mobile population Concentration of population in specific areas Getting more familiar with PC and multimedia High productivity requires working, shopping, banking and Internet access Expect wire-line quality and global roaming 3

4 Emergence of 3G Mobile Service Demands for high quality voice and fast data What to get is more important than How to access Internet is the global infrastructure for communication and commerce Current wireless access can not afford internet Killer application services not clearly defined yet 4

5 Emergence of 3G Mobile Market Rapid increase in number of subscribers Increased competition More competition for operators, more options for users Market goes to truly global Convergence of different networks Diversification of user base 5

6 What is 3G Mobile? Third generation (3G) mobile service Aims to unify the diverse systems Called IMT-2000 Service up to the rate of 2,000 Kbps Service provided at round the year 2,000 Service at 2,000 MHz band 6
