  4. Objectives • High network capacity: more simultaneous users per cell • A data rate of at least 100 Mbit/s between any two points in the world • Seamless connectivity and global roaming across multiple networks • High quality of service for next generation multimedia support

  5. USERS OF 4G • The Japanese company NTT DoCoMo has been testing a 4G communication system prototype and is planning to release the first commercial network in 2010 • Digiweb, an Irish wireless broadband company recently started to use it • Verizon Wireless and Vodafone are getting together to establish 4g networks soon. • Sprint also announced that it is going to launch it in 2008
