CDMA / GSM
There have been a lot of GSM phones coming out lately - seems to be less of CDMA ones. And GSM being what it is, the new phones usually have better and more capabilites. Setting aside the new v710 motorola, i dont see many potentially great phones that will compliment Verizon's CDMA cells.
And with Vodafone losing its bid on AT&T wireless, how long will it take Verizon Wireless to begin its steps to develop a GSM network of their own? Verizon is known for the quality of their calls in its CDMA network, but, will it ever make a move toward GSM?
Thanks for any replies.

i don't think that verizon's gonna be moving to gsm in the near future. the reason is that the gsm network isn't as mature as the cdma one -i mean, it is not nationwide yet, and the reception in some country areas, specially in the ATT network, is extremely poor-.
verizon is a leader in cdma, and many of their customers choose it because of its reception. it is much better for verizon to wait and see the gsm network getting consolidated, rather than going to a new standard, maybe losing its leading position in cdma.
it's gonna take more than three years for verizon to switch definitely to the gsm standard.
i hope i got wrong, though...

Yeah, thats true. At the same time other carriers using the GSM standard are expanding their network. It seems as though companies like Cingular will have a good, or at least decent GSM network that other countries enjoy. And unlike CDMA, GSM can potentially work on 4 frequencies, correct? With the 800 and 1800 being the world standard - correct me if I'm wrong here. Anyway, with this fact, aren't GSM carriers one step closer to developing an "international network?"
I also hear Verizon is trying to slowly fade away AMPS. I know their network isn't all-digital, but how much of it is?

Verizon isnt looking into changing to gsm at all. Right now the focus is on improving the existing network (which is the largest in U.S.) and offering customers that do travel overseas the ability to use a phone there (samsung a790).
...
good 4 them in the short term. let's see what the market may be requesting in 2005/6. but anyway, nice pick 🙂

Your are all so wrong. CDMA or WCDMA will become the wordwide standard. This is due to one major fact. GSM can support EVDO/EVDA broadband speeds.
...
don't think so... gsm transmission speed is much faster, and europe and latam, for example, are switching from cdma to gsm.
...
if you wan't to see what CDMA can do, look to asia, CDMA there is seeing 3.0Mbps downstream speeds, GSM/GPRS won't ever touch that. [(period)(end of discussion)]
...
You ALL are incorrect! Let me get this a little straightened out.
GSM/GRPS/EDGE is the European standard at the moment.
AT&T Wireless, and Cingular (soon to be combined), as well as T-Mobile are the three major contenders of this service. It /IS/ nationwide service, just not even 40% as expansive as ther aging TDMA networks, and even smaller in comparison with VZW's phat CDMA network.
From GSM/GRPS/EDGE, they'll be upgrading (AWS the only one vocally explaining their path), to UMTS, which is 'Universal Mobile Telecommunications Systems'. The technology its based on, is WCDMA (Wideband Code Division Multiple Access). This is only really based on CDMA in name, the technology is very greatly different, and better. It will offer speeds (wh...

yup, in that case US is way behind the european and asian standards; in latam, for example, many of the countries could develop a 1900 mhz gsm network in less than two years...
...
Moobak, I don't know who you work for, but thank God someone can post the truth, and do it in a rational and intelligent way.
...
Um, not exactly... 🙄
CDMA 1xRTT is much faster than GSM GPRS. With the addition of EDGE, GSM is slightly faster than CDMA, but only slightly, and with EV-DO or EV-DV, CDMA leaps ahead - it's WAY faster.
And Europe is not dumping CDMA - they never had it.

...
that's not totally correct...it's a standard w/ several flavors that hopefully all GSM and CDMA will move towards.

Nope. But with a few minor changes, you'd be close:

nobleecho, the thing is that the gsm network has 4 frequencies, as u have accurately said.
these frequencies are 800/900 mhz for country areas, and 1800/1900 mhz for urban areas. regarding these frequencies, u are right, even though some carriers in europe, such as Vodafone, or some others in latam like movistar, or its subsidiaries, work in 1900 mhz. i have the c333g, i live in argentina, luckily i have a 1900 mhz carrier and i am experiencing the greatest reception ever!!!
GSM will become a global standard, no doubt. and i hope the amps users for Verizon know soon the difference whenever the network goes to digital, even on the cdma format. i heard that they are switching to digital, and they are telling our customers to get rid of their...

There are actually a lot of new CDMA phones coming out. LG alone announced something like 12 new CDMA phones at CTIA this year, including the awesome VX-8000. Then there's the Motorola V710 and A840, the Nokia 6255i, and the Kyocera Koi. There will always be more GSM models worldwide, just because it's a bigger market, but I wouldn't say CDMA is suffering or fading in any way.
Vodafone originally wanted Verizon to move to GSM, but they've given up on that. It would be way too expensive, with not enough benefits. It makes much more sense to stick with CDMA - Vodafone knows that. It's an investment for them, and a switch to GSM would be a guaranteed way to lose money on that investment.

but then what after ev-do? GSM will have UMTS but CDMA seems to be at a dead end.
...
First, EV-DO is much faster (for download, at least) than UMTS, so if it were a dead-end, it would be a better one.
But there are no dead-ends. After EV-DO, there's EV-DV release C, then EV-DV release D. That last one is pretty awesome, and totally blows UMTS out of the water.
But UMTS (WCDMA) isn't a dead-end, either. After that, they will have HSDPA, and upgrade that makes WCDMA 3-5 times faster and more efficient.
It's always an endless game of leapfrog. TDMA (specifically, IS-136) is the only dead-end technology.

speaking of analog, do you know who they are gonna auction off the analog spectrum when they start pulling it in '06?

There's no separate spectrum for analog - it's just plain old cellular spectrum at 800(850) MHz.
Companies like Verizon and Cingular have, of course, been phasing out analog for quite a while. As they've done that, they've been switching increasing portions of the cellular spectrum they own to digital. In 2006, they'll be able to turn off that last little slice of analog and immediately use it for digital service.
So no auction - that spectrum is already owned and being used mostly for digital. The only thing that changes in 2006 is "most" becomes "all".

thnx.
i was under the impression that they were going to kill of the analog spectrum and auction it off which was puzzling me a bit. what you said does make more sense.

...
You might have been thinking of TV. They've already started auctioning off the old analog TV spectrum at 700 MHz, with more to come. Digital TV will free up a lot of spectrum in that range.
...
that's probably what it was. i knew about them doing that to tv and probably was thinking the same with cell. thnx.

Let me just start off by saying that I have been a Verizon customer for almost 4 years. I live in Westchester County, New York which almost demands that you have Verizon due to every other carriers inadequate coverage. However, I recently went to Jamaica and purchased a Nokia 6600 which is a tri-band GSM phone (900/1800/1900) and activated it with ATT Wireless. While Verizon may have better "network" coverage, there is really no comparison with respect to call quality and the features of a GSM phone. ALL Verizon phones have a very tinny sound and sometimes have an echo problem. You get a signal with Verizon in more places than with any other GSM carrier in this area, however, when you get a GSM signal the call quality is far superior to...

haw, one of my former co-workers told me there was no way he could do this job without coming to work high. i guess it was getting to expensive to work here so he quit.

Wow, dayum good thing they stopped drug testing huh ya lil REEFERS :þ I always thought you guys sounded half stoned on the phones lol.

and the fact is that verizon's cdma network is more exapansive than any other GSM carriers digital network. Besides, wouldnt you rather have a phone that works in more places (plus the superior call quality that muchdrama stated)?
Although i do have a question of my own. Is NTT Docomo's FOMA network in Japan UMTS, GSM, or CDMA?

CDMA IS a superior technology to GSM in terms of codecs, call density, etc - no debating. I used to market and sell RF test equipment to the major cell phone providers and manufacturers and knew the ins and outs of all the various standards. Having said that (and having also traveled lots to Europe for business) GSM coverage, quality in Europe crush what's available over here. We all know the phones are much better, but the services offered by GSM carriers in Europe are superior as well (to both what GSM and CDMA carriers offer here). However, the ubiquity of the GSM standard in Europe, as the above poster mentioned, doesn't mean it's superior, it just means it's ubiqituous.
I clearly got better coverage and call quality in Europe than here...

i keep hearing about the CDMA network in korea, but what is so different about it? im sure it uses different frequencies than the CDMA networks in America but what else makes it great in that sense?

It would also be remiss for me to not point out that CDMA quality and services in South Korea in my experience rival or trump what's available in Europe (and of course are much better than what Verizon/Sprint offer here).
I'll bet they have cooler phones as well.
...
What do you think the reason is that service is better in Europe and Korea? Why is the quality of service better? More cell towers, towers closer together, or better quality infrastructure?
I've never been to Europe or Korea, but I do know that cellular service here is the US leaves something to be desired. I know there is a problem in lots of areas of major cities and esp. suburban areas here is the US where they don't want those "unsightly" towers built in their neighborhood.

...
I think it's mostly a common infrastructure - that everyone's on the same standard, and both because of this and because the physical land mass to be covered is much smaller, and they've had networks in place longer, that the tower density is just much greater. I mostly used an Ericsson T200 in Europe which is/was just an OK phone from an RF perspective that would usually get 1-2 bars over here - but it almost never dropped below 4 bars of signal strength in Europe, and no dropped calls.
