UMTS Overview. • 2G Wireless Systems. – GSM, CDMA One (IS-95). – Wireless voice communications, SMS, Basic Data. (EDGE, GPRS). • UMTS (Universal . System Architecture. • Network elements are grouped into. – User Equipment (UE) that interfaces with the user. – UMTS Terrestrial RAN (UTRAN) that handles all.

The design of the architecture was further optimized through iterative
Figure 2.1 WCDMA Network. 2.2. SYSTEM ARCHITECTURE. The UMTS utilizes the same well-known architecture that has been used by all main second generation systems and even by some first generation systems. The reference list contains the related 3GPP specifications. The UMTS system consists of a number of
Divider modulus is a periodic function of time. 0 Reference frequency can be greater than the resolution frequency. 0 In-band gain is reduced when reference frequency is increased. ==> lower in-band noise. 0 Typically, loop bandwidth of PLL can be increased compared to integer-N divide ==> faster lock. 0 Spurs
