UMTS Technical Description (WCDMA)

Course Highlights

UMTS (W-CDMA) is one of the third generation wireless systems. UMTS is designed to increase a subscriber’s data rates and system capacity. This course offers a technical overview of UMTS, focusing on the UMTS air interface (WCDMA), radio network and core network. It covers the network architecture, components and basic operations of UMTS networks. In addition, this course explores the details of the W-CDMA air interface technology and its ability to support multiple subscribers simultaneously. Aspects of CDMA technology pertaining to W-CDMA Air Interface including coding, modulation, spreading, scrambling, handovers and power control mechanism are clearly explained. This course then focuses on circuit-switched and packet-switched core networks. The key concepts in the course are tied together with several system scenarios to provide insight into location management, mobility management and handovers. The course concludes with an overview of the UMTS road map outlined by 3GPP from RLS99 to RLS10.
