1xEV-DO vs. UMTS/WCDMA
Can someone please enlighten me on the differences between these new technologies and which one is better? My contract is running out with Verizon and I am thinking of going to cingular, but I want to make sure I will be on the network that is on the right track with the newest and best technologies.

Looks like it. Is it as efficient as CDMA/EVDO/EVDV? No...but who really cares about that if their handset is capable of blazing fast data?

Theyre both gonna be fast,I just wish that these companies would put as much energy into new codecs for better sounding service,ie CDMA, and less background noise,ie GSM

I don't think EV-DO will influence the voice channel too much (please correct me if i'm wrong)... But I know the recommendation by Ericcson as far as implementation of WCDMA involves a WCDMA overlay and GSM more as a net to catch the call should it fall off of WCDMA... To improve dropped calls and take full advantage of WCDMA...
So, the phone to always remain on WCDMA (which will in by itself present better call quality)... If the handset is out of reach of the WCDMA network or doesn't handoff to a WCDMA tower it will revert to GSM (avoiding call drops)... Then first chance it gets drop it back into the WCDMA network... Wether or not Cingular will use this method is what we'll find out... It seems like the best route to go... and it's th...

Whoa! Good call speck. evdo is just data. no voice. i just hope cingular can whip out the umts/hsdpa network as fast as it did gsm. they rolled out gsm and high speed edge in under a year!

WCDMA is a complete network rebuild and about half of the Cingular markets are former ATTWS markets. It took them almost 3 years to rollout GSM.
About the time WCDMA is rolled out it will be competing against either EVDV, CDMA3k or 802.16. Either way even with HSPDA, UMTS will only roughly be the equivalent of CDMA. Spectrum will be an issue since UMTS is a spectrum hog. If there are a large amount of data users it will pinch the voice users and vice versa.

Where are you gathering your facts? Based on your comments Cingular started rolling out GSM 6 mo. - 1yr that they were first in the wireless industry... Does that honestly make sense to you? The truth is Cingular rolled out GSM in less than a year. Faster than it took ATTWS to... ATTWS just had a head start. WCDMA is already testing in some markets and will be readily available in a majority of markets late 2005/early 2006.
You really have no clue what you're talking about do you? You just stated that WCDMA will be the equivalent to CDMA... before you argue this point... UMTS/HSDPA == WCDMA... If that is the case then why can't CDMA hit the speeds WCDMA is reaching currently throughout the world... Why must there be another 3G to even com...

Are you serious?
Cingular started their rollout of GSM in late 2003. After just 6 months, they had 80% of their entire network overlayed in GSM/GPRS. They completed (100% of their towers) the GSM overlay in less than 1 year. They have released EDGE in the majority of their network even faster yet.
There have already been press releases by the top executive positions of the company speaking of their determination to release WCDMA as quickly as they did GSM. With an HSDPA upgrade soon thereafter. If their speed at rolling out GSM is any indication of how fast they could roll out WCDMA, Cingular will have this network up and running at the same time or slightly after Verizon completes their EVDO upgrade.
HSDPA has the ability of a...

Yes, but just as GSM is the stepping stone to UMTS, EVDO is the stepping stone to either one of the EVDV releases or CDMA3k or even 802.16.
The fact is that both the UMTS community and the CDMA community will counter each other and be competitive. This discussion will continue until one or both succumb to the other or another technology.

UMTS with an HSDPA upgrade has recorded speeds of up to 14.4 mbps right now and will be being released alongside EVDO that has speeds of up to something around 3 mbps. I'd imagine it would take a few more of those stepping stones to even match the 14.4 mbps possible with HSDPA which is Cingular's answer to Verizon's EVDO, not EVDV, CDMA3K, or 802.16. You can't deny that there is a considerable gap between the speed of the two technologies.
I'm curious, is there any recorded speeds of EVDV, CDMA3K, or 802.16? If so I'd appreciate it if you could provide some. It would be nice to know how they compare to UMTS/HSDPA.
