25 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

26 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 IMT-2000_UTRA_TDD_FDD_26
