Is Europe worried about CDMA carriers?

There's 3 Flavors of 3G CDMA:
CDMA2000
WCDMA
TD-SCDMA
which one will win depends on Europe.

I think gsm is a given over there. Cdma no chance.

 

Ummm, the upgrade path for GSM is a form of CDMA. How can it not have a chance, when it is currently being deployed by European operators?

 

WCDMA is added to GSM,
and is reverse compatible.
What he really means is CDMA2000
is No Chance in Europe.

A lot here confuse 2G CDMA
w/ 3G CDMA.

3G GSM is WCDMA.
Europe Developed its own CDMA,
not worried about it.

The Fight is Now
WCDMA Vs CDMA2000 Vs TD-SCDMA

The Thread title is wrong to begin with.
It should be
Is Europe afraid of CDMA2000?

 

CDMA2000 will not become a mainstream option for Europe. UMTS (aka WCDMA - same meaning) is already being heavily invested in. Some European countries do have CDMA networks (i.e. Romania) as well but they won't impact the development of UMTS since the license auctions were already overly expensive.

We won't see CDMA2000 period....end of story.

 

I agree with that one ShoresGuy.

I can't see any of the Europeren providers going to CDMA2000.

 

Europe is a much larger continent than is Western Europe.

WESTERN Europe will likely remain the dominion of wCDMA, however the rest of Europe has many CDMA2000 networks.

 

What european countries are those?
They really mean the whole europe,
east or west.

The following European countries have CDMA and CDMA 450:

Just so you are aware, UMTS is not added to GSM, it is a totally seperate network and in no way compatable with GSM, the only reason that the 3g phones that are available now are "backwards compatable" is because they actually contain 2 different radios, one for GSM, one for UMTS. In Europe for example, the UMTS networks are in the 2100mhz bands, here in the US, Cingular is just going to use the 1900mhz band for both.

Which is why it is possible to be in a call and do data at the same time, not hard to do when you are accessing 2 different networks.

There is one reason, and only one reason CDMA never had a chance in Europe, its because it belongs to an American company, thats why they decided to use the GSM standard. Can you imagine how rich Qualcomm would be today if they did decide to use CDMA instead of GSM????

But now there are CDMA networks popping up in Europe in the 450mhz band, I would hope they come up with some tri-band phones so that CDMA customers here can access those networks in the future.

 

HArdware is added to GSM.
Though the phone has 2 Technology.
UMTS is using its own spectrum.
Like an Analog/CDMA phone,
GSM/umts phone.

Handoff between
GSM and WCDMA is No problem though.

 

Iwas looking for the CDMA Numbers outside North America
so i guess this confirms it.

Yes, thats what i ment.

 

There are 683 licensed GSM operators in 213 countries worldwide today.

In the year 2005, GSM added more than 81 million customers in the Americas alone compared to 30 million CDMA customers; worldwide, GSM added 391.9 million new customers, far exceeding the entire customer base of any other mobile technology.

 

Isn't cingular also going to add UTMS in the 850 band as well as the 1900 band?

 

I thought UTMS and HSDPA could do voice and data at the same time without the use of the GSM band?

 

Yes, they sure will. The reason why UMTS and HSDPA will be in the existing GSM 850/1900 bands for the US is because the FCC hasn't opened up a new frequency range for UMTS use. The 2100 Mhz block is still reserved for MSS (Mobile Satellite Service) purposes.

 

what's PDC? and where does FOMA fit into here?

 

I think PDC stands for Personal Digital Cellular, it is a TDMA-based Japanese standard operating in the 800 and 1500 MHz bands.

Do you mean FOMA or FDMA? If you mean FDMA, then I think it's use is minimal to none today. Wasn't FDMA used exclusively for analog cellular systems, even though in theory FDMA can also be used with digital? It was very inefficient anyway, so it got replaced by digital networks TDMA and CDMA.

If you mean FOMA, then I don't have a clue, maybe Jones Knows........

Just my 2 cents.

 

GSM is TDMA and utilizes FDMA,
as way of Frequency Hopping.
As it Moves in Time slots,
it also Moves in Frequency.

 

PDC and FOMA are 2 Japanese network standards developed and used solely in Japan.

PDC was developed as a 2G standard based on TDMA and located in the 800 Mhz band. At its peak, it had 80 million subscribers but that number has now dropped to 46 million due to newer standards being implemented.

FOMA was developed as Japan's and the world's first true 3G/UMTS network standard by NTT DoCoMo in 2001. It is compatible with regular 3G/UMTS networks used in other countries. At the moment, FOMA has 15 million subscribers in Japan and continues to grow as more and more Japanese users shift to 3G.

Thanks Shores that explains. I knew about PDC but not about FOMA. I guess then I would ask why FOMA is not on the chart that Jones posted. At 15 million it should be between IDEN and Analog, right?

 

I don't know, it might have been left out since it's an exlusive network standard used solely by NTT DoCoMo.

 

When I looked at these charts last week in Japan, I assumed that FOMA numbers were just folded into wCDMA or UMTS numbers on top of GSM since that what FOMA is...UMTS

The DoMoCo phone I rented in Japan had UMTS and tri band GSM. It operated on DoMoCo's and Vodaphone's Japanese 3G network.

 

Its a given that CDMA2000 makes more efficient use of spectrum, but that doesn't intern mean customers really care. As long as GSM can operate the same applications, and call block is not an issue, thats all they care. Carriers that are already knee deep in GSM are not going to up and decide to switch everything over to CDMA2000 even if they wanted to.

 

FOMA was most likely folded into the UMTS numbers. This makes sense today, since NTT DoCoMo is making FOMA UMTS compatible.

 

I think Dogma hit the nail on the head; most customers don't care. Mobile geeks like us debate the pros and cons of GSM, CDMA, EVDO, UMTS, etc ad infinitum, but I doubt whether most Europeans will be terribly interested. Most people are probably more interested in whether the end product works rather than the technical details.

CDMA 2000 isn't going to be a factor worth considering in Europe, the networks have invested too heavily in GSM and WCDMA to bother with another standard. I think one also has to realise that there is massive interdependence in Europe; some companies own networks in more than one country and even those who don't have to contend with a great deal of travel between countries. A single unified standard isn't only desirable in Europe, it is necessary.

 

Don't forget UMTS-TDCDMA. Sprint Nextel is taking a long hard look at this one for part of their 4G network.

 

@jrip

I was under the impression that 4G was something different to UMTS and other 3G standards.
