UMTS satisfies the real needs of the end-user
✚ Personalized and highly customized
✚ More individual bandwidth
✚ Always-On
✚ Global roaming
✚ Seamless network, UMTS-GPRS-GSM
✚ Rich Multimedia services: Information, Transaction, Entertainment
= my services - anytime - anywhere - on my device
IMT-2000_UTRA_TDD_FDD_25
28.09.2001
UMTS-UTRAN enhances capabilities of 2G:
! Lower Delays can be reached
!
Faster access, due to the new radio interface
!
Faster transmission, due to higher datarates per individual connection
! More and new spectrum is allocated (and more efficiently used!)
! Improves coverage in hotspot areas
! Handover to/from GSM/GPRS/GERAN is assured
