So, I have a contract with a local network that uses CDMA 1X. I have had my current phone with them for a while, but I am wanting a new one, and I don't like any of the phones they have. I have been looking at various phones and really like the Nokia 3555, which uses WCDMA 1700, 850/1900 or 850/2100 -- The question is will the 3555 operate on CDMA 1x?

Nope sorry it will not. The Nokia 3555 is a GSM phone, which is a totally different technology.

Like Charlyee said, it is a GSM phone, even though it is W-CDMA compatible.

W-CDMA is part of the GSM evolution, not CDMA, despite the similarity in name.

UMTS, HSPDA, HSUPA, and W-CDMA are all related via their connection to GSM. They seem to be used interchangeably. Even though the flow is more like UMTS/W-CDMA > HSPDA > HSUPA> then to LTE eventually.

The forward path for CDMA 1x is CDMA Rev. 0 > Rev. A > Rev. B > then to UMB eventually.

(Techies, if I'm wrong or missing something, please correct this).

This was just posted a few minutes ago, so you can also count LTE as a possible evolution in the CDMA networks.

Yeah, I noticed the article on Phonescoop after I originally posted this. Thanks Jay.

Ah, bummer, that would figure. So does CDMA 1X go by any other names that I could look for when searching for phones on manufacturer's websites?

No just look for CDMA 800/1900. It can be 1x, 1xrtt, EVDO......

LTE is not an evolution of CDMA networks. CDMA operators are changing tracks to LTE because the evolution of CDMA (UMB) is dead before it started.

Evolution tracks:

3GPP: GSM -> GPRS -> EDGE -> UMTS -> HSDPA -> HSPA -> eHSPA -> LTE
3GPP2: CDMA -> EVDO -> UMB -> ?

*Note: 3GPP and 3GPP2 are not related at all.

20 or 30 years ago French was the "international language" for buisness and diplomats. Today it changed tracks to English. Is English an evolution of the French language? No. Neither is LTE an evolution of CDMA.

Please forgive me, I have mispoken. What I was trying to say was that LTE could be a viable path to follow now that the technology exists to make the handoffs possible.

The 3GPP Pope forgives you

...the next few years you'll see alot more inter-technology handovers. T-Mobile allready has handovers to WiFi, CDMA to LTE was just demonstrated. Sprint's WiMAX will have to hand over to other technologies. It's all about "Convergance". Stay tuned...

Sorry are these LTE's could be classify as 4G generation of GSM? What about CDMA, is it UMB? What is UMB, i search on Wiki, could found it on CDMA articles

LTE is the next progression in GSM's evolution. UMB is the next for CDMA. Verizon will be using LTE instead of UMB so the4y are compatible with international roaming with Vodafone, their parent company. Other us based CDMA carriers may also go to LTE if their coverage depends on roaming with Verizon.

cheddar · 03-31-2008, 10:04 AM

Is anybody going with UMB or have carriers decided it isn't worth and they're just going to go LTE eventually? Last I heard companies like Nortel weren't even working on UMB gear.

Also has anybody heard of WIMAX being used to replace a CDMA or GSM network? I know its being deployed in newly allocated frequencies but has anybody said they're going to migrate their existing networks to WIMAX?

Sprint is dabbling in WiMax. Verizon and AT&T have already announced they are going LTE. I'm not sure if TMO has announced, but since they are a GSM carrier LTE is a logical choice. Alltel will probably go LTE because Verizon is. Alltel, and the other smaller rural & regional CDMA carriers depend on Verizon for urban coverage. It is very possible that once the jump to 4G is made all US based carriers will be LTE, with the exception of Sprint.

It depends. Although Alltel will likely go to LTE. They actually don't use verizon all that much anymore. It's all sprint with vzw as a second or third roamer. So there is some potential for a different option...

RadioFoneGuy · 04-01-2008, 8:07 AM

LTE was originally designed for for the GSM evolution path but having some CDMA interworkings devolopers saw an oppourtunity thru Mimo and multiple chipsets that it could work with existing CDMA netoworks.

After the Motorola Test Alltels interest in the test is a good indicator of things to come.

This what I think the carriers will look like.

LTE AT&T, Verizon, Tmobile, Alltel, USCC

Wimax? Sprint for now, but with economic issues they may run Wimax hotspots for data only and remain on the CDMA path for now. Just my thoughts.

gpatrick900 · 05-01-2008, 9:01 PM

Here what I was told by a Verizon store person.

That Verizon will keep there CDMA network up for quite awhile.

700 mhz CDMA Voice, LTE Manily for Data and other features.
800 Mhz CDMA Voice, Basic Text Message
1900 Mhz CDMA Voice, Basic Text Message

So, if you use a CDMA phone, you will not have to throw it out for quite sometime.

I can not see pageplus, getting there own phones. Verizon will have to provide them with some new phones.

I am agree wirh Charlyee. someone guide you wronge.

NASA is also considering going with LTE, but Globalstar is considering WIMAX for its advanced Global Satellite coverage, but so far there are no commitments on witch technology both might choose... However when I learn something on the goverment sector i will post it...
