Abstract
The main goal of this paper is to review the most recent development of new technologies related to the topic of the high-speed packet data of wireless Internet and potential applications. This paper will provide an overview of HSDPA and will focus on the business values that such a highly-efficient access technology will bring to wireless operators, including higher capacity and newer services. The key mechanisms of HSDPA and the performances will be explained. The other future evolutions like HSUPA or MIMO and OFDM will also be presented. HSDPA increases the downlink data rate within a cell to a theoretical maximum of 14Mbps, with
2Mbps on the uplink. The changes that HSDPA enables include better quality and more reliable, more robust data services. In other words, while realistic data rates may only be a few Mbps, the actual quality and number of users achieved will improve significantly.
Keywords : HSDPA, UMT, 3GPP, HARQ, CQI.
