masa, This is not the food fight board and you are fast losing credibility with your sweeping, unsubstantiated statements. Give us some details and you will earn our respect.

c2, << 3G is mostly WCDMA >> What happenned to CDMA2000 1xRTT Release Zero? <g> Irwin, Perry, and Bock Communications, have gone to great lengths to attempt to convince the world that what used to be an interim step to 3G, really is 3G. <gg> Sheesh! 3GSM UMTS WCDMA will not even be "commercially viable" for another month or two. <ggg> But on a more serious note ... << the momentum worldwide is solidly behind WCDMA, a system that will not be replaced by 4G for some time, at least a decade if not longer. OFDM is of absolutely no relevance to this dynamic. >> You might want to listen to Motorola's Analysts Day presentations (they really put on a great show), and pay attention to their comments about the introduction of OFDM into 3GPP (some time ago), Qualcomm's recent introduction of OFDM into 3GPP2, Motorola's push for OFDM standardization in a mobile environment in IEEE 802.16 (as opposed to 802.20 wher qualcomm holds court). You also should note the Korean introduction of OFDM in 2.3 GHz using Samsung IP, the Japanese efforts with OFDM, etc. While I agree with you that 3G systems will not be replaced by 4G - whatever 4G turns out to be - for some time, it is highly likely that complementary OFDM technologies will be introduced into 3G network platforms on some scale in this decade, portable first, then mobile, long before standardized 4G is defined. Starting this year we have had several product introductions of multi-mode, multi-band OFDM (802.11x WiFi) and GSM GPRS/EGPRS smartphones or converged PDAs from Nokia, HP, Motorola and others, and they will be shipping in commercial quantities starting this month. [I'm not ready to invest in MOT, but Ed Zander is a pretty impressive CEO. I do highly recommend a screening of their recent Analysts Day presentations, which improved my perception of the state of this recovering company.] Best, - Eric -

I did not say that something will replace 3G any time soon. But believe me, one day, OK maybe ten years from now, there is a new better system that has replaced or is gradually replacing 3G. What comes to OFDM, Eric L. already answered pretty much on behalf of me. There is a lot of activity around OFDM today.

Every WCDMA player of any consequence, and some of no consequence whatsoever, has agreed to pay Q for its IPR. At this moment in time, I would consider it close to a certainty that all CDMA2000 and WCDMA carriers will remain firmly in the QCOM IPR sphere for at least one more generation, HSDPA and DORelA. I've heard nothing to indicate anyone will veer off via OFDM of any kind, in fact, I have heard from quite a few trial participants that Flash-OFDM performance is not on par with the above, so there isn't even a technical case, let alone a business case. I think we are all well aware that what comes after HSDPA and DORelA is in play(technology wise) within 3GPP and 3GPP2, although an early peek does seem favorable to QCOM IPR. We are also well aware of OFDM progress in freq bands above 2.1GHz and within the 802.x standards bodies, and I would consider it a virtual certainty we'll see a lot of success there for OFDM. But for now, everything is looking sweet!
