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
