Cha2,
<< WCDMA Exists >>
Yo Da Man! Reciprocally, HDR Exists.
<< I am curious how 1X fails to meet 3rd gen standards in your view >>
First let me explicitly state Chaz, that I am talking about 1x as it is currently standardized in Release A - Phase Zero (which translates to the MSM5000 chipset that will start to ship commercially shortly). I am not talking about 1x Revision B which is in progress, and so far as I can discern will be voted in December, and may include 1xEV=DO, but not so far as I can tell 1xEV-DV.
The standard (as it exists) and the soon to be shipping chipset allow for peak data rates of 144 kbps (maybe thats 156 kbps).
<< It is approved, no? >>
IS-2000, Release A - Phase Zero is indeed approved and this is what the North American PR guys, Hypsters, and Spinmeisters are hanging there hat on when they call what is about to be implemented at SK-Telecom, "3G", and at least on this side of this Atlantic or Pacific aren't even bothering to call it an "interim step" to 3G, which is what they were calling 1x last year.
Now, let me ask you a few questions back.
1. Is that 144 kbps at full mobility?
2. What about 3G speed in a stationary environment?
3. What about 3G speed in a pedestrian environment?
4. What about interoperability with other modes (particularly DS)
Is this "3G"
<< What about the "connection" of bullet train speed and 3 G speed? >>
Full Mobility
<< So what is the missing element? >>
See questions 2, 3, 4, above, and perhaps item 1.
<< Is it because it can be used in current spectrum? >>
Strictly speaking, No. This as a result of the WRC conference in Istanbul.
Practically speaking, somewhat yes, as I think that those nations that set aside spectrum in the 2GHz range for IMT-2000 services Europe, Korea, Japan), or those nations that will shortly (Brazil, China) tend to still use this differentiator for distinguishing between 2G-2.5G/3G.
<< Again, I see focusing separately on current spectrum for now as the most practical for the next year or so. >>
Thats 2.5G for all practical purposes. Now as a 2.5G standard, and deliverable, 1x blows the doors off GPRS, and TDMA-EDGE although standardized is just vaporware.
... and this indeed presents an opportunity for Qualcomm in current spectrum. This is why I think the recent transfer of GSM/GPRS standards development from ETSI to 3GPP is so significant, particularly as it relates to China. The decks are getting cleared, potentially for cdma overlays of a GSM-MAP network, with no worry about having to have ETSI bless.
<< Future spectrum is just that - the future >>
But contracts are being let now, and the future is near, and we have some important decision being made within 30 days in Korea, that most certainly affect Qualcomm shareholders for the intermediate term, and actually (because of financial analysts reactions to these decisions, for the short term).
