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

Universal Mobile Telecommunications System (UMTS) as the successor to GSM. The UMTS utilizes the W-CDMA, TD-CDMA, or TD-SCDMA air interfaces in which WCDMA is the most prominent air-interface innovation for the UMTS. The primary segments incorporate BS (Base Station) or gesture B, RNC (Radio Network Controller), aside from

the asynchronous CDMA modes of UMTS. 3. IMT-2000 CDMA TDD (IMT-TC): Includes UMTS Terrestrial mode of access (UTRA) TDD [15] mode equivalent or TDD WCDMA standard, and the Chinese TD-SCDMA (Time Division Synchronous CDMA) where Time Division Duplexing is used to share a channel between uplink and downlink, with the
