Hi Cha2,
<< Suggest you may have hit a major point which I was trying to deal with in making a distinction as to which CDMA flavor works best in which set of spectrum >>
I am, BTW, not ignoring your original post on this subject. You suggested a good format for ongoing discussion of this. I'm trying to phrase the proper response.
In the interim, Qualcomm investors should not be overly concerned, IMO, with the fact that DS UMTS will become the predominant 3G mobile telephony standard.
DS UMTS is CDMA. MC (1x to 1xHDR to 3X) is the CDMA migration path Dr. Jacobs courageously assured for IS-95 carriers.
3G is Multimedia (not just voice and data). We are just across the chasm on wireless voice and data , nowhere near on multimedia. Meantime, CDMA continues in hypergrowth with lots of voice, and a little data.
CDMA was commercialized by Qualcomm. They figured how to regulate power for it. CDMA is an extremely complex air interface compared to TDMA, GSM, GPRS.
You can NOT work around QCOM IP in CDMA. The only alternative is to find an alternative like GPRS & EDGE) and in attempting to do so, you lose time and spectral efficiency.
Hey, it would be great if everybody adopted cdma2000 for 3G. Won't happen. The open standard will dominate, but thats tomorrow, not today.
