Philips Selects InterDigital´s Advanced HSDPA Technology For Its 3G Platform

InterDigital Communications, the designer, developer and provider of wireless technology and product platforms, announced an agreement with the semiconductor division of Royal Philips Electronics to bring InterDigital´s HSDPA technology into the family of Nexperia cellular system solutions. HSDPA (High Speed Downlink Packet Access) technology will provide to mobile phones and other mobile devices a fast, cost-effective way to download email, music and video content and to surf the web.

InterDigital offers its standards-compliant HSDPA solution as a set of technology blocks for incorporation into existing UMTS Release 99/Release 4 chips or as a separate coprocessor chip for initial deployment. The advanced receiver-based technology solution supports Category 10 functionality, efficient power control and delivers quality of service enhancements and is scalable to Release 6 of the standard, High Speed Uplink Packet Access (HSUPA) technology.

HSDPA technology is an optional upgrade available for WCDMA/UMTS networks and terminals. It offers a seven-fold increase in theoretical data speeds (14Mbps) for the downlink compared to today´s WCDMA networks (2Mbps). In real life, these theoretical maximum data rates are rarely achieved, but the practical performance of HSDPA can be compared with current ADSL broadband, whereas WCDMA is more comparable to basic ISDN. HSDPA not only offers higher raw data rates but also it is much better designed to handle IP traffic. Therefore, end-users will experience faster response times and shorter download times. They can also download packet-data over HSDPA at the same time as having a speech call.
