InterDigital Communications Corp. has signed an agreement with the semiconductor division of Royal Philips Electronics to bring InterDigital's High Speed Downlink Packet Access (HSDPA) technology into the family of Nexperia cellular system solutions. The HSDPA technology is expected to provide 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.

Philips is a long-term, high-volume supplier of full semiconductor system solutions for cellular phones, from ultra low-cost GSM-only handsets to multimedia-rich EDGE and UMTS feature and smart phones. These system solutions contain all the ICs and the system software. Via the Nexperia Partner Program, Philips brings IP (Intellectual Property) or software from 3rd parties into these system solutions, which is complementary to its own IP, to make the solutions more complete or versatile or to optimize time to market.

HSDPA technology is an optional upgrade available for W-CDMA/UMTS networks and terminals. It offers a seven-fold increase in theoretical data speeds (14Mbps) for the downlink compared to today's W-CDMA 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 W-CDMA 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. End-users will experience faster response times and shorter download times, and also download packet-data over HSDPA at the same time as having a speech call.
