Evolving the capabilities of IS-2000: an overview of 1XTREME

Third generation (3G) wireless systems supporting voice and data services have been proposed since 1997. Standardization of those proposals was completed in 1999. However, anticipated demand for data services, particularly in the area of wireless access to Internet-based services, is driving the need to enhance the data-carrying capability of these systems beyond their current abilities. Yet, those resulting systems must continue to provide traditional voice services to an increasing subscriber base. This paper provides a brief overview of enhancements proposed to the IS-2000 system called 1XTREME that needs these needs.
