America's First WCDMA Call 225
k-hell writes "Ericsson and AT&T Wireless recently completed the first WCDMA/UMTS call in a live network environment in the Americas, capable of data transfer speeds of up to 384 Kbps. AT&T Wireless and Ericsson currently pursuing the path to 3G capabilities in the U.S. market by deploying EDGE-ready GSM/GPRS systems. This path ensures an evolution to EDGE, then UMTS, a wideband radio technology that provides mobile users with data rates up to 2 Mbps." This is not yet a strong enough reason to move to Dallas, though.

In any event, I pay about $80/month for unlimited service. The only down side is that the connection works by buffering and bursting in 500ms intervals. The server saves up 500ms of traffic and bursts it all at once. Then the modem responds. Completely useless for online gaming. Also it drops packets like a mofo. Methinks there is no real error-correction system between the modem and the cell-towers.
Still, it beats 56k modems.

Re:Up to xxx Mbps... until it gets customers (Score:2)
There are different circumstances with data than there is with voice. With voice, the requirement is that you have a constant connection with a minimum bandwidth and a minimum latency. Standards for data trasmission would be much more relaxed. It's okay to wait a few seconds to get a burst of data. At best, most of the cell phones will be bursty instead of constant download streams.
There are going to be people that use the phone to keep their computer on the net constantly. You can bet, though, that the service providers will provide incentives not to use the internet phone much. For example, they'll charge you by the kilobyte. Maybe one day that'll all be worthwhile, but for the first round I'm reasonably sure that they won't have saturation issues.
I do whole heartedly agree with your 'up to' comment, though. Seems like it'd be more useful to post a practical data average. Of course, they'd inflate that # too. heh.

Texas is a huge flat land mass located in the southern portion of the united states. It borders the carribean and has fairly nice weather (except for the occasional tornado) These geographical features are what makes it so appealing to wireless development.
Also to note are the remote oil fields that depend on pump yeild data that is usually sent wirelessly because it's cheaper in terms of right of way. So basically there's a demand in texas for anything new in wireless data transfer.

D-AMPS, aka TDMA (latter name not good because GSM is also TDMA) - Used by Cingular and AT&T until recently
GSM - Used by T-Mobile. Cing and AT&T are rolling out GSM. GSM doesn't seem to handle multiple providers in the same area very well, as numerous T-Mobile customers are complaining about their phones going into "Emergency service only" mode as soon as Cing and AT&T roll out service in their area. Used in Europe by legal mandate.
cdmaOne - Qualcomm's original CDMA implementation. Used by Sprint PCS, Verizon, Qwest, Telus Mobility in Canada, and (I believe) Centennial Wireless in Mexico.
2.5G services:
GPRS - The GSM high-speed data enhancement. 40ish kilobits/sec
CDMA2000 1xRTT - Evolution of cdmaOne, 144 kilobits max in initial versions, later going into the 200s-300s. Backwards compatible with cdmaOne - cdmaOne handsets work with CDMA2000 networks and vice versa, which allows providers to do partial rollouts for market testing/high-demand areas.
3G services:
UMTS - The 3G evolution of GSM. The GSM people realized their modulation scheme was inferior, so moved to a CDMA variant. Unfortunately, almost all the companies with CDMA expertise are behind CDMA2000, which means that the UMTS camp is having trouble getting anything to work well, especially handsets. (Most well-known problem right now is battery life - No mention was made about how long the battery used in this test would've lasted.) NTT DoCoMo rolled out UMTS in Japan, their name is now mud. Completely incompatible with GSM/GPRS. Requires new handsets, new base stations, and new spectrum.
CDMA2000 1xEV-DO - 3G evolution of Qualcomm's CDMA technology. From what I've heard, like 1xRTT it's backwards-compatible back to cdmaOne. i.e. a provider rolling out 1xEV-DO doesn't have to upgrade their entire network at once. Already in use in Korea and also I believe by KDDI in Japan (KDDI might only be using 1xRTT - Either way they're mopping up DoCoMo because their service actually works.)

After that, download speeds aren't too bad if you stick to wireless versions of sites. (Heck, if I were still on dialup instead of DSL, I'd use those at home - fewer ads, too!) I'm not watching streaming video or playing Counterstrike on the road, anyway.
With things like the Treo, where the phone and PDA are all in one unit (or even just with a Bluetooth link between them), and the ability to quickly pull it out, sign on in less than three seconds, get info, and put it back in your pocket, then it might be worth it. To some people.

As I see it, the biggest selling points for 3G data service are the availability and security associated with it. While one can never be completely secure over anything wireless, certainly, when coupled with stronger encryption, 3G can promise high speed security. Most people who need an internet connection for business purposes will likely pay a premium for always-available, secure data services.
For the casual user, I do see 802.11b as being "just fine." So what if someone is packet-sniffing my Yahoo.com mail account? I'm really not doing anything important. However, when data services become both ubiquitous and inexpensive, we may find users who cut the line on their cable modems and DSL connections and go wireless. (Kind of like we are seeing a transition from land-line phones to cellular.)
Of course, there are also issues such as network saturation, which I feel are being grossly overlooked. I mean, I regularly can't complete calls during the evening hours (when the other 26,000 people at my University are also using their free night and weekend minutes.) I can't imagine what it would be like with data services on top of that!
In short, I see the cellular phone as an application of a broader wireless platform. The platform is now beginning to be used to transmit data, which is a perfectly appropriate use of the technology. Over the next few years as 3G becomes more wire-spread, we'll see how things shape up. It will be interesting to watch.
