I guess one of the things that I am unclear about is the following comment which keeps appearing: "There has been a lot of discussion about the SpectruCell implementation of CDMA without the need for Qualcomm chipsets. To clarify things a bit, Qualcomm does not own CDMA, it owns a specific hardware based implementation of CDMA. This is the IS-95 specification." I was under the impression that the QCOM patents for CDMA were for the air interface abilities to afford soft-handoff and power regulation. I question that claim of this being a hardware-only based patent, for it deals with the ability to do this, not necessarily with their chipset. Perhaps the hardware accomplishes this function, which would of course be another patent for the hardware design. Could you please address this area with greater specificity? Thanks, Martin Thomas

"To clarify things a bit, Qualcomm does not own CDMA, it owns a specific hardware based implementation of CDMA. This is the IS-95 specification." This doesn't appear to be a correct appraisal. Note the patents which NOK, ERICY, NTT and MOT have been challenging and losing: European Patent Number 705512, entitled ``Method and Apparatus for Determining the Data Rate of a Received Signal'' covers an invention that is essential to the current commercial CDMA standards as well as third-generation (3G) standards. The invention, which is also useful in other, non-CDMA communication systems, makes efficient use of bandwidth by enabling voice data to be transmitted at a variable rate without the need also to transmit data identifying the transmission rate. European Patent Number 521859, entitled ``Direct Digital Synthesizer Driven Phase Lock Loop Frequency Synthesizer with Hard Limiter'' covers a frequency synthesizer that requires substantially less space, hardware and power than conventional synthesizers and is applied in a number of integrated circuit and telecommunications products. European Patent Number 666007, entitled ``Mobile Communications Device Registration Method'' discloses a technique for accurate monitoring of a mobile phone within a cellular system and is essential to the practice of a number of CDMA industry standards. Japanese Patent No. 2763099, the Japanese version of QUALCOMM's first CDMA patent originally filed in the United States in 1986(U.S. Patent 5,103,459) and granted in Japan in March 1998. The patent, entitled "Spread Spectrum Multiple Access Communication System Using Satellite or Terrestrial Repeaters," claims inventions that are essential to all viable commercial CDMA standards, including the two third-generation (3G) standards, known as W-CDMA and cdma2000, to be deployed in Japan. European Patent No. 0667068, entitled "Dual Distributed Antenna System" enables enhanced coverage and increased capacity in communications systems, especially indoor CDMA systems, and mitigate the adverse effect of fading which can be severe in the indoor environment. European Patent No. 0695492, "Method And Apparatus of Providing Audio Feedback Over a Digital Channel" covers an audible feedback feature that gives the user the ability to monitor audibly the progress of a fax or modem connection over a digital channel. Korean Patent No. 134390. This patent is essential to both second and third-generation CDMA wireless telecommunications standards. The patent entitled, "System and Method for Generating Signal Waveforms in a CDMA Cellular Telephone System" describes inventions for generating the basic CDMA waveforms used in CDMA wireless systems such as IS-95 and in the proposed 3G standards. If Advanced Communications Technologies can bypass QCOM's patents, something the engineers from Ericsson, Hitachi, LGIC, Lucent, Matsushita, Motorola, Nortel, Philips, Samsung, Sony, Sanyo and Toshiba can't seem to accomplish, because they have all licensed 3G from QCOM, why aren't they licensing the technology, or at least telling these companies not to license, and they'll cut them a sweet deal? BTW, if they really talked to QCOM, they would know there is no such animal as "minimum licensing". You need one, you buy them all. They sell a patent pool. Additionally, anyone can develop a system without QCOM's license, they just can't sell it. Kent
