Philips Selects InterDigital's Advanced HSDPA Technology For Its 3G Platform;
Integrated Solution Offers High Data Rate Capability, Efficient Power Control
and Rapid Time-to-Market

    KING OF PRUSSIA, Pa.--(BUSINESS WIRE)--Aug. 3, 2005--InterDigital
Communications Corporation (Nasdaq:IDCC), a leading designer,
developer and provider of wireless technology and product platforms,
today announced an agreement with the semiconductor division of Royal
Philips Electronics (NYSE: PHG, AEX: PHI) 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.
    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 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.
