INTERDIGITAL PRESENTS INVENTORS' HALL OF FAME AWARD TO
DR. DONALD L. SCHILLING AND SCHOLARSHIP TO DREXEL UNIVERSITY

Company Recognizes Outstanding Achievements in the Innovation
of Wireless Technologies


King of Prussia, PA, May 6, 2002 . . . InterDigital Communications Corporation (Nasdaq: IDCC), a leading architect, designer and provider of advanced wireless technologies and product platforms, inducted Dr. Donald L. Schilling as the first member of InterDigital's Inventors' Hall of Fame and presented a scholarship in his name to the graduate program at Drexel University. The presentations were made during InterDigital's annual Inventors' Dinner on Saturday, May 4th at the Franklin Institute in Philadelphia. Philadelphia-area based InterDigital, with additional research and development centers in Melville, New York, Montreal, Canada, and Munich, Germany, has designed and developed digital wireless telecommunications technologies and products for almost 30 years.

Chairman of the Board Harry Campagna stated, "I am extremely proud of our inventors for their significant achievements in digital wireless technology design and development. The contributions of our inventors are embedded into mobile products in use today and in development for the next generation of wireless products. The inspiring work of our people has created technology that is a valuable asset to InterDigital and to our industry.

"In particular, it is with great pleasure that we recognize Dr. Donald L. Schilling for his many contributions to CDMA technology and pioneering work for InterDigital in the early 1990s. Dr. Schilling was the founder of a CDMA development company called SCS Mobilecom/Telecom, which InterDigital acquired in 1992. When our companies joined forces, we gained the great benefit of Don Schilling's leadership as a pioneer of CDMA technology. Our combination put InterDigital on a path to become one of the world's leading developers of CDMA technology platforms and products. We applaud Dr. Schilling for his inventive contributions and profound impact on the wireless industry," continued Mr. Campagna.

"Drexel University is delighted that its relationship with InterDigital has been strengthened with the establishment of the Donald L. Schilling Scholarship Fund, which will support graduate students whose research interests focus on wireless telecommunications," said Kevin J. McNamara, Associate Vice President at Drexel. "Drexel also is proud to count many alumni among InterDigital's executive leadership team. We look forward to strengthening the relationship between our University and InterDigital."

InterDigital also recognized prolific inventors for their increasing contributions to significant digital wireless technologies in use today and in development for next generation wireless products. InterDigital presented Plateau Awards to several employees for their accomplishments in reaching certain milestones in the number of patents for which they have been named inventors. Award recipients included Mike Regensburg, Vice President, Programs, for 5 issued U.S. patents; John Kaewell, Senior Vice President, Advanced Product Development, for 10 issued U.S. patents; Ridge Bolgiano, Vice President and Chief Scientist, for 10 issued U.S. patents; and Fatih Ozluturk, Vice President and Chief Architect, Product Incubation, for 20 issued U.S. patents.

Howard Goldberg, President and Chief Executive Officer, presented the President's Award to Fatih Ozluturk for having the most patent applications granted in his name during 2001. Mr. Goldberg stated, "I am delighted to present this award to Fatih Ozluturk whose work constitutes an important part of our third generation technology platform."

Harry Campagna presented the Chairman's Award for the most valuable invention filed in 2001 to Eldad Zeira, Ariela Zeira and Steve Terry for their work on Dynamic Link Adaptation for Time Division Duplex. This winning invention implements dynamic link adaptation by adding or changing control information to notify the receiver which timeslots and codes are currently active and which timeslots should be avoided. Commenting on this award, Mr. Campagna said, "This award represents an extremely significant technical achievement considering that we filed 103 U.S. patent applications last year, a 151% increase over 2000. This is a highly competitive award selected from an outstanding pool of talented inventors."

mschere, sure wish par-q, IQ, or somebody comfortable walking around in the deep wireless tech stuff would show me where I'm wrong(if I am?) in reading that "seamless" handoff patent in your ref post. I have spent hours trying to understand what it says, and it just keeps saying "Holy smokes! Batman, InterDigital wants to flip the whole wireless industry on it's head, this could change everything!".

Check this out, and then take a look at the underlined words in the patent excerpt from you ref post below. All wireless systems today are designed to operate from the top down,i.e., the network of base stations is in charge and decides to recognize a subscriber unit(handset or mobile phone), what kind of service level to give each handset, and when, where and how to handoff that handset to another base station. The base station is King in today's wireless world, and the hansets take whatever the base stations decide to give them.

Dr Faith M. Ozluturk has a very different idea according to what I'm reading in his ref patent. From what I can figure out Doc Ozluturk wants to make the handsets King, and turn the base stations into servant transmission towers! Yikes! That has to sound like total anarchy in the rest of the wireless industry, especially with the engineers. It throws everything they have right out the window, and has to blow out most of the logic circuits in their "top-down is THE way" heads. I bet the propellers on a lot of Nokia engineer hats really spin up a storm whenever "seamless" or "Ozluturk" gets mentioned. Same thing at the Ericsson base station design headquarters LOL! Gotta be plenty of breeze in those halls if I'm reading this right. Take a look;

6. A mobile subscriber system that controls cell hand-off in a multicellular CDMA communication system while roving among individual cells, each cell associated with a base station which transmits a global pilot code, where the subscriber has a preexisting communication link with one of the base stations, (snip)

; and means for establishing a new communication link and abandoning said preexisting communication link to thereby define said new communication link as the preexisting communication link when said minimized transmit power between said mobile subscriber and said selected base station is less than the transmit power of said preexisting communication link.

7. The system of claim 6 wherein the means for acquiring said valid global pilot code further comprises:

means for selecting a global code seed associated with one of said plurality of candidate base stations from a plurality of global code seeds stored in a memory;

means for searching for a global pilot code using said selected global code seed; and

means for performing said search to a maximum expected phase shift between the preexisting communication link and said selected candidate base station.

8. The system of claim 7 further comprising means for synchronizing said transmission between the mobile subscriber and said selected base station.
