Complete 2G/3G dual-mode protocol stack Available from InterDigital

January 16, 2006

InterDigital Communications Corporation announced the availability of an integrated, standards-compliant, dual-mode 2G (GSM/GPRS/EDGE) and 3G (UMTS) protocol stack for integration into mobile terminal devices.

The complete dual-mode protocol stack is available for integration with existing dual-mode baseband solutions. Alternatively, the single-mode 3G stack can be integrated with existing GSM/GPRS/EDGE designs. Key features of the solution include the following items:

-- Global Certification Forum (GCF) -certified legacy 2G protocol stack with 75 type approvals and interoperability tested by more than 80 operators in 40 countries;

-- 2G/3G dual-mode protocol stack completed ten interoperability tests with major equipment producers and operators;

-- 2G/3G dual-mode protocol stack GCF certification expected in early Q1 2006;

-- High data throughput performance - customer-based interoperability tests validated peak data rates of 384 kbps in UMTS offerings;

-- Adaptable to future releases including UMTS Release 5 scheduled in Q1 2006 and UMTS Release 6 scheduled in the second half of 2006;

-- Seamless handover between GSM/GPRS/EDGE and UMTS networks.

"A key initiative for us has been to create a comprehensive product offering that we can offer to terminal unit manufacturers in a complimentary fashion with our strong patent portfolio," noted William J. Merritt, InterDigital's President and Chief Executive Officer. "The recent licensing of legacy GSM/GPRS/EDGE technology from Infineon Technologies AG (Infineon) completes a high value dual-mode protocol stack that both expands the target market for our product offerings and creates new synergistic offerings for handset licensees."

InterDigital's integrated dual-mode protocol stack is comprised of Infineon's 2G protocol stack and the 3G protocol stack co-developed by InterDigital and Infineon. InterDigital offers full customer support from initial integration through product introduction.
