Overview of release 99 WCDMA

Abstract

This chapter provides a brief overview of WCDMA release 99 to serve as a background to subsequent chapters. WCDMA is a versatile and highly flexible radio interface that can be configured to meet the requirements from a large number of services, but the focus for the description is the functionality commonly used to support packet-data transmissions. The goal of this description is to provide sufficient background to the underlying release 99 WCDMA specifications such that HSPA and the HSPA enhancements that are described in subsequent chapters can be seen in context.
