It'll be good for Verizon to join in with the rest of the world, and have true global compatibility once they get off CDMA2000/ANSI platform.

More like 2010 or 2011. They aren't going to twiddle their thumbs while WiMax is going up.

well I was looking at the even bigger picture. When they switch over completely from CDMA.

they will not be switching from cdma. this is not a gsm vs cdma for lte is not gsm. sometime on the future verizon might move the network to lte with voip but not anytime soon as they still dont have the spectrum for 4g at all.
...

They will switch eventually hence the time frame I gave.

When will you guys learn that LTE is NOT GSM. Its just a 4g data network. One of the main reasons why VZW is going to LTE is due the their main competitor ATT. Since ATT will also have LTE, they can roam off each other which will boost the size of the LTE network once both companies have it up and running. But VZW is NOT switching to GSM, they have and will always be CDMA. If they were to switch to GSM it would take they them to build a whole new network, replace ALL of their customers handsets, and much much more. Again, LTE is not GSM, just a 4g data network.

says who? Verizon would not sign a deal with sprint to roam using EVDO so why would they let att? You said main competitor not main friend!
...

The reason why Sprint and VZW can't roam of each others data network is actually not due to signing any deal. When I worked for sprint I found that their setup for EVDO was different. Yes it was the same technology but the phones would have to be configured when switching networks.
...
wombough

Dec 29, 2007, 12:20 PM
oh please they are the same. They don't want to give access to the network due to many reasons as has been discussed on here. EVDO is EVDO alltel and sprint worked it out.
...

Dec 29, 2007, 4:48 PM
That was my understanding as that is what was told to me when I worked for Sprint. I could have been told wrong as someone might have mistaken these differences for the whole BREW/JAVA issues that VZW customers have had.
...
wombough

Dec 29, 2007, 4:55 PM
maybe. Alltel and verizon use brew. Sprint java. But EVDO is EVDO and they can roam but verizon does not want their spectrum used. be it they can't handle all th etraffic or whatever they would only sign a 1x rtt data agreement with sprint.

If you look at the post under this topic, people are thinking that it is GSM and that VZW is switching to GSM.

Although it may not be a direct evolution of GSM technology, LTE is still part of the GSMA global standard. It was developed and adopted under the umbrella of current standards including GSM, UMTS and HSPA...and will continue to be considered a 3GSM/4GSM technology.

No I know its not GSM. I never said it was. Its as GSM as Wimax is CDMA.

You are correct in stating that it was accepted by the GSMA Global Standard group but just because its accepted by that group doesn't mean its GSM. Its only considered as a 4g network architecture technology, not a 4GSM. The actual standard is called 3GPP Release 8. What you guys get confused is the fact the GSM is a voice only handling part of a network. The data runs on different spectrum's. This is why you have dual/tri/quad-mode phones. Each spectrum of the network handles a different voice and/or data of the network. Now LTE can handle data and voice and you might even see phones that make data calls but that doesn't mean its GSM.
...

I thought the reason that there are dual/tri/quad-mode phones is because that is the frequency that specific countries set up for wireless mobile services ๐Ÿ˜ณ

Having multi-mode phones has nothing to do with that. Data and voice can be piped through the same band with GSM. It has more to do with setting aside bandwidth in a particular band. Hence why ATT phones are 850/1900 with GSM & WCDMA both occupying those bands.
...
dublea

Dec 29, 2007, 5:09 PM
ROFL!! If that were true, then Sprint & VZW wouldn't have tri-mode phones. You have two CDMA bands (analog/digital) and one EVDO band. The different bands on GSM are for analog/digital/international/edge. Its going to be the same when WiMAX comes out for Sprint. I think wombough said it best..

Its as GSM as Wimax is CDMA.

I think you guys are getting on the wrong track. I work for Verizon network engineering and the freq.(band) has nothing to do with voice or data. We have EVDO on 1900MHz in Atlanta, but in south GA it is running on 800MHz. LTE was originally designed as an upgrade path from UMTS networks,but it has been modified to overlay CDMA networks also. Verizon chose LTE for its global roaming capabilities.
...
wombough

Dec 29, 2007, 10:07 PM
what global roaming capabilities? There is none yet. And there is no definite plans on who will deploy what were! Except Sprint and verizon and vadaphone in the UK
...

Verizon and Vodaphone want to have the same network technology because they are so closely tied in with each other. There seems to be no other true tech. path other than Wi-Max right now, and nethier company wanted to go down that route. I believe that most companies will want to follow in the big boys footsteps because of economies of scale bring lower prices and it will be a better experience for consumers if their phones work all over the world.

Please relay to me this mysterious "one EVDO band". Verizon uses EVDO in both 800 and 1900. TDMA/analog is still running because a small piece of the bandwidth in that particular band "800" is allocated for that use. So I will end this by saying the reason their are different bands (800, 1900, 2100, 1700, 2.5, or whatever) is because that is where the government said you could have mobile services. EVDO or WCDMA can be provided in all of these bands "as long as the provider has sufficient bandwidth". Also, I agree with Wombough's comment. I was just stating that you were wrong or you worded your post horribly ๐Ÿคจ
Maybe I just did not understand what you were trying to say ๐Ÿ˜•

About Verizon switching to a GSM network? I'm not arguing that LTE is GSM, i'm just asking whats up with all the GSM hating?

GSM is less effecient, meaning it cant handle as many users per channel as CDMA. CDMA is less prone to interference, meaning less break-up during conversation. There are other factors, but too many to list. Go to Wikepedia and it will tell you the differences between the two technologies.
...
Adam7986

Dec 31, 2007, 2:29 PM
Alright well I looked into a little further and although CDMA does have a higher user per channel rate it is not always guaranteed, (average of 15-50 users) and it only has 20 channels, GSM only has a solid 8 full rate users and 16 half rate, but with 124 channels. after some math even at is peak performance, CDMA only out does it by 8 users so its not a very good argument.

As far as call quality, every bit of information I have read, aside from Verizon and Sprint, and out of personal experience says that GSM has a clearer, better quality and is more secure. Bottom line neither are going to be good if you don't have a decent signal.

I would be interested in what other factors you have besides the data transfer rates being faster.
...

Dec 31, 2007, 2:49 PM
I dont understand where you get the number of channels. The number of channels depends on the amount of spectrum a carrier has in a given market. For example, Verizon has 22MHz of spectrum in the Atlanta market, you can fit X number of 1.25MHz(channel size CDMA) channels in the availiable spectrum. If another GSM company only hass 22 MHz in the same market, the CDMA carrier will be able to handle more callers hands down. especially in metro areas where there will be low power levels. At the lowest power level, you can fit 58 callers on one channel(CDMA). With GSM it is only 7. The 8th time slot is reserved for the paging channel.
For voice quality, GSM may be clearer during peak traffic, but it is more likely to have interference. ...

Maybe I read the channel information wrong, the link is:

http://www.rfcafe.com/references/electrical/wireless ... »

No matter who develops the network it does not always mean its more secure, and certain parts of the GSM frequency bands are used by the government. And I am still going with call quality on GSM over personal experience living in a metro area (downtown Dallas).

The whole point of my response was not to start a which is better debate, but to ask if it really would be all the bad if Verizon switched to GSM? Or even Sprint for that matter, to me it seems like it would be a benefit to the consumer if we had a national standard. Not that carriers would change just the technology.

Eventually, there will be one standard and everyone will be happy. Wouldnt that be nice? Mabye your phone would work everywhere regaurdless of carrier or tech. or freq. I cant wait.

CDMA is more secure its a fact. Also from my experience talking on a CDMA phone is clear as my landline. GSM not so much. Its getting better as they have updated their codecs. Verizon would never switch to GSM as the world is getting away from GSM. Switching to WCDMA. Even here ATT and Tmobile will eventually carry voice and data over WCDMA like in Japan.
