Well that was alot of rambling. So let me get this straight, overnight the billions of dollars put into GSM, CDMAOne & TDMA will be render useless by the troika of Ericsson/Nokia/NTT 3G standard. A standard that is also going to support compatibility? Ah- huh. So much for ammortization of all those company assets. No Qualcomm didn't invent CDMA. Bell Labs did and probably hold the most patents on it. Qualcomm however solved the problems in deploying it in a wireless system. Do you know what the real difference is between QCOM version of CDMA and Ericsson's? About 3.75 Mhz of bandwidth per channel. That is it. Still far more wider than the legacy narrowband GSM system. But by Ericsson OWN admission, they abandon CDMA becasue they couldn't get it to work. Now they had a brainstorm?? Well lookie here. Why setlle for 5Mhz channels, shoot let's make it 6!!!!! As to your claim that QCOM stole from GSM, where did Ericsson steal it from? The only reason we started out with analog in cellular instead of digital was microelectronics wasn't there yet. There in fact was a great debate whether they should wait until digital could be resolved. The demand was to strong to hold off. As a matter of fact LD and interconnection of PTSN was already long migrating into digital by the time cellular first came out, which BTW is TDMA. Now, geewhiz, wonder what the GSM system is model after?? Steal, indeed!!! You say QCOM steals from Ericsson. Well just what kinda of error correction does Ericsson use in GSM? LEt see........he works for QCOM...holds personally a great many of patents himself......Dr. Viterbi ring a bell. Viterbi decoders are a BIG part of GSM. So who stole what and when?? Frankly, I'm sick of these "US is behind the times" nonsense. #G is going to be in the frequency range that PCS is in. The one major reason QCOM decided on 1.25 Mhz channel was the way the FCC envisioned PCS being divide up. Think that Europe or Japan will have five class of license for this service?? The FCC is dragging their feet on LMDS issuance. Winstar with it's frontier license is building out a very formidable wirless system that was orignally for digital video, but is instead going for Internet and voice now. By the time Europe bastardize this standard, we will see what they have. This is the same collective that mandated ISDN service for GSM, where is it?? It got cannabalized for voice via ADPCM techniques, stolen from whom???
