Now a days there are two different technology for mobile phones in the world.
(1) CDMA -Code Division Multiple Access
(2) GSM - Global System for Mobiles based upon TDMA ( Time Division
Multiple Access)
There are some countries where GSM is the major technology and CDMA has entered recently like India. On the other side there are some countries where CDMA is the main technoloy and GSM has entered recently like USA, Canada as far as I know.
What you think about these. I mean which technology you like and why??? And which will win in the race between these two in the future.
I work in the industry and being from Europe obviously I'd have to say GSM. Technical both technologies are level pegging. Some would argue that CDMA is better quality. But to the average Joe you cant tell the difference.
GSM however is a much more globally standardised technology. For this reason international roaming is excellent with GSM. There is so much international roaming in Europe therefore GSM is used 100%. However CDMA isnt as internationally accepted. Great in your own country but if you want to travel somewhere else the chances are your CDMA phone wont work.
Interestly, the GSM standards group have adopted WCDMA (Wideband CDMA) as the basis for the next version of GSM (i.e 3GSM).
I suppose the debate doesnt really matter as we will all be using WCDMA in 10 years time.
In Europe all the companies are upgrading their systems to that technology.
I use GSM myself, like many people and I believe most of Australia has access to a GSM network, although mine is sometimes non-existent.
Therefore, I voted CDMA, but as I said, it's called WCDMA.
In Canada, it's being introduced later this year!
I can't wait!

The First GSM phone I had was in Germany through Vodofone. Then when I got back to the states Cingular offered a dual TDMA/GSM phone. I used that for a couple years then switched to a Motoroloa V60 series GSM (I think it was the 170 or 160, I can't remember). Now I have a Razer V3 through the Cingular Go service.
Why I do the monthly plan linked to my debt card just as I did before with the 2-year plans. The nice thing is if I can get a really good deal through someone else, I'll join, if I need to go to Germany for 6Months, I can just cancel my month to month with no $150 fee...it works for me...

In Europe, CDMA has never existed... in fact GSM has been arround for decades. UMTS is in fact a technology used in GSM ... So therefore GSM IS the future as UMTS belongs to GSM.
You can also tell this by the fact that the latest phones in US were obsolete in Europe nearly 10 years ago..
CDMA as well as Analogue where dead many years ago.
) were coming out with a new data network I think Verison just beat us to it called HSDPA (High Speed Data Packet Access or something) its pretty interesting double the speed of the CDMA providers network right now. With data and now video calling starting to become the norm it will all depend on data speed not call quality in my opinion.-Jordan
I would check the coverage maps before actually getting in bed with a cell carrier.
But there are Pro's and Con's about both..In India at least, CDMA handsets do not hold a SIM card. So you can't change your handset (or its not as easy a process). I often bet with my friends and we're shuffling between our handsets, thanks to versatile SIM cards! Besides, CDMA is used for cellular as well as FWT services. In case of FWT, I think that's the best solution for quality.
But of course, GSM is an internationally accepted standard. And people tend to roam. So all odds favor it - for the compromise in quality, we would use GSM technologies in the future. I didn't agree upon that SMS taking a long time to be sent thing though! I've never seen that around!
whereas GSM is used in most of the countries and it has several enhanced features like, GPRS, EDGE etc.

You work for Rogers Communications Inc.? They are the only Canadian provider to use GSM.

and, i can bet tht UMTS is not long from overtaking the rest!

I think what matters most is the uniformity of the mobile technology. Mobile phones are about communication so it is important to make sure that the message/phone call is sent to the recipient, regardless if it is GSM or CDMA.

Here in Australia, the big telco has just starting phasing out the CDMA network to make way for the third generation network it has recently deployed around Australia. This means, by January next year, there will be no more CDMA in Australia!Link: view Post: 106982
Does that mean your country can only use 3G phones then? 3G is still quite expensive to use and implement, not ideal for the consumer.

Telstra has almost finished implementing 3G coverage across Australia. Because the 3G handsets can roam on the 3G and GSM networks, this means that people with 3G compatible handsets have more then, i think they said 99% coverage over Australia.
I don't yet have a 3G handset, only because I don't need it. Yes, the extra speed that the EDGE network has is great, but I just dont need it yet. And as you said, its quite expensive! To purchase a 3G phone is very expensive, though Telstra has just released 3G Pre-Paid, which will be good for some people. You can even watch Pay-TV channels on your 3G mobile now!
Although I remember when Erickson said CDMA would never work. They kinda got egg on their face over that one.

I'm using both GSM and CDMA (I have 4 handphones with 4 different numbers, 2 GSMs and 2 CDMAs). There's no favourite. They have their own functions.
GSM : 1 number for Internet via GPRS, and another for my wife's communication
CDMA : me and my wife. usually CDMA is bad for text messaging and the signal is poor, sometimes we have to recharge the batteries often because the handphones try to look for signal.
telstra are getting rid of their cdma service next year anyway.
i have a next g phone, i prefer next g. the internet on it is so much faster!
Yet I have some friends who have GSM (AT&T phones), and their service is awful. It'll show full signal...but the number of dropped calls....or the fact that the phone won't ring one minute, but be in the exact same spot and ring the next....Or even better when you call them and you get this nice little voice saying something along the lines of "Welcome to AT&T we are sorry but this user is currently unable to receive phonecalls at this time. Error blah blah" (now that isn't exact but it is something like that....and why on earth it wouldn't go to voice mail I have yet to figure out)...but that has been my experience with GSM service...
Also, there are no WCDMA plans for Canada. I work in the mobile phone industry both for my employer (in a technical capacity, but I am not at liberty to name them, and with my own startup company that works with mobile data delivery
Technically speaking, CDMA is superior and offers several technical benefits (greater data transfer speeds, greater reception and range, less susceptible to dropped calls), but since it is a patented technology it is not free and its use incurs royalties for the cellular provider. Because of this, and because GSM already boasts 8 times as many users, and therefore the more important market for phone manufacturers, GSM and then UMTS will win out and that's a shame.

CDMA vs GSM
I'll try to make this short and clear. I have a student plan (non data) through bell. I want to get the HTC 6800 but don't want to buy it through Bell because they will make me sign a data plan and another contract to get a decent price. I have found a couple of the phones on Ebay but they are American.
My questions are:
1. Will an American CDMA phone work with Bell? Does it have to be unlocked like the GSM phones?
2. Since this isn't a Bell manufactured phone, will the Wi-Fi work?
Thanks!
-Curious Bell Customer
