Caxton,
<< I am a qcom groupie ... but I am fairly sure we all agree that cdma2000 out performs WCDMA as the article below states >>
Are you addressing that to the other qcom groupies, zealots, and missionaries that populate this thread?
WE here, do not ALL agree on that.
Looks like the carriers of the world do not all agree on that.
Me, ... I'm just a qcom investor and although I have a great deal of respect for long time CDMA perma bull Andrew Seybold, I don't yet, and may never, agree that cdma2000 out performs WCDMA.
How could it?
Right now 1xRTT outperforms WCDMA only in the sense that it exists in a commercial trial where initial debugging is taking place, using a trial chip that is noncompliant to the IMT-2000 IS-2000A standard, and WCDMA, by contrast, does not exist in any commercial environment.
We have seen some slideware from the mother house that suggests that 1xRTT (and 1xRTT combined with 1xEV) based on QUALCOMM simulations is more than 2x as efficient as WCDMA and that WCDMA is only 3x as efficient as GSM ... which means that WCDMA missed its design goals by a wide margin ... and I'm not quite ready to bet the ranch that is the case.
The same company that brought us this slideware, once claimed that IS-95A CDMA was 7 to 10 times as efficient as GSM, but by the time they commercialized their product, the half rate vocoder was on the GSM scene, and as it turned out most people could agree that IS-95A was 3 to 3.5 x as efficient as GSM. Now despite that, until 3 months ago CDG had a statement on their web site that stated that cdmaOne was 4 to 5 times as efficient as GSM ... and that might be true in the desert.
Maybe we should wait till we get some real world feedback on this ... and we won't have that this year.
Next month WCDMA will commence its existence in a similar environment (Tokyo) to that in which 1xRTT birthed (Seoul). There will be 4 handsets from 2 manufacturers supposedly available at outset (compared with Seoul where there was 1 for 1), Supposedly they will offer peak data rates of 384 kbps as opposed to 144 kbps at outset (and SKT originally said max peak was 115 kbps initially for 1xRTT, not 144 kbps).
Heck, 384 kbps v. 144. A WCDMA groupie could say that WCDMA out performs cdma2000 or at least 1xRTT Phase ZERO - if it in fact achieves these rates - and who knows whether it will or won't.
Me, I think I'll wait for 1xRTT to be integrated with 1xEV, for cdma2000 and WCDMA undergo QoS optimization, enter the general deployment stages, and watch get comparative feedback from sources other than Qualcomm and CDG (or Nokia, Ericsson, and GSMA) ... before I make a even a preliminary determination of whether cdma2000 outperforms WCDMA, or vice versa.
It may be a long wait. cdma2000 has to standardize, debug, and commercialize several of its family members before we draw valid conclusions.
By then I guess we can start to compare 1xEV-DV to HSDPA.
<< They put on a full court press to convince carriers to go with an inferior technology through financing and bribes (buying stakes in current cdma operators) >>
Heck, these dirty birdies might even buy 3G spectrum next, so WCDMA will be deployed in the IMT-2000 core band instead of cdma2000.
Just a reminder here. 3GPP WCDMA is the carriers technology choice, and it is the standard they evolved, and continue to evolve.
<< Turn on high speed data as its needed to maximize capacity. That is why I own qcom. >>
I own qcom because in January 1998, 3GPP chose CDMA as their primary air interface, and existing and new GSM carriers will deploy it as needed to maximize capacity, and to offer multimedia data services, and when they do, QCOM gets paid.
I also own qcom because back when I bought it, cdmaOne was the "fastest growing" mobile wireless technology in the world, and the comparatively seamless cdma2000 migration path was a "no brainer" for cdmaOne carriers, or so we thought.
I sure didn't buy it on the strengths of 3GPP2 cdma2000 as an ANSI-41 based, end to end, third generation global technology platform. If I had, I'd take one look at the score card and ditch it.
... but I'm not ditching it.
Still waiting to see how 1xEV unfolds ... and interested to see if there is any application for it outside the ANSI-41 world ... which will require some standardization for starters, and as of one month ago that effort had NOT commenced.
<< The main reason Nok is buying WCDMA contracts is they are afraid. >>
Right. Shaking in their boots.
They are "buying" WCDMA contracts from carriers that have not for one moment considered a cdma2000 solution, because cdma2000 doesn't offer an interoperable solution for GSM carriers building out in IMT-2000 core spectrum.
From my perspective ... as a NOK investor ... they are spending money wisely, because they are gaining infra market share, and they are in a position to do so.
Maybe QCOM should do some network financing. They have a good balance sheet. The key members of their value chain in the infra arena, do not.
Over 100 3G licenses have been awarded for IMT-2000 spectrum. Over half of the licensees have awarded contracts. Has a single cdma2000 contract been signed yet for IMT-2000 3G?
<< nok is the lead dog of the evil empire >>
Make that THE EVIL EMPIRE!
Lead dog is a promotion. Used to be lead dog ERICY.
Happy Easter,
