GSM and handoffs in WLAN. But first UMTS is introduced and the different levels and parts of the system are described. 3. Introduction to UMTS The third generation mobile communication system UMTS (Universal Mobile Telecommunications System) is successor of GSM (Global System for Mobile Communications). UMTS networks can be divided in two parts.
Chapter 1 : UMTS Overview 1.1 Introduction Universal Mobile Telecommunications System (UMTS) is a 3G cellular telecommunication system. It will be the successor of GSM. UMTS is designed to cope with the growing demand of mobile and internet applications with required quality of service parameters. WCDMA is used for the radio interface of UMTS. It
