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
28.09.2001IMT-2000_UTRA_TDD_FDD_26
UMTS-UTRAN enhances capabilities of 2G: 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
