Description
Summary:In the last two years, UMTS has progressed from the drawing board to prototypes and pre-release trials. Through the concentrated efforts of manufacturers and operators in the standards bodies, the 3GPP specifications for UMTS, including W-CDMA, TD/CDMA and TD/SCDMA, are currently being developed into deployable equipment for the first UMTS networks. However, human nature dictates that there is always room for improvement, with a constant drive for better performance and higher efficiency. UMTS is by no means the ultimate mobile radio access network, and, even before the first equipment rolls off the production lines, the work of the standards bodies is already looking at enhancements to the system. This paper considers some of these improvements, the evolution of W-CDMA, and the role of TDD in the ongoing developments of third generation mobile radio access. [PUBLICATION ABSTRACT]
