In Gainesville, Fl, phones that use the GSM network barely get signal compared to the CDMA phones. I was a customer of Sprint for 2 years, and while the plans sucked, the call quality was great. My girlfriend is a Cingular customer, and she keeps getting dropped calls. We laugh at all those commercials that say Cingular has the fewest dropped calls, because for anyone attending the University of Florida, Cingular is the worst! Tmobile also uses GSM technology, and while the signal is a bit better than Cingular's, it still stinks compared to Verizon and Sprint in Gainesville. So, I chose CDMA for my part of town. If I'm traveling to another country, I always carry a quadband phone and pick up a sim card there.

In a local area the difference maybe more apparent, but as a global traveler I use GSM exculsively. With GSM I can go to most countries and get a signal. Currently I'm with AT&T through work. (Still keep the Go Phone for personal/back up use) and I can go to Europe with no problems and same with SE Asia. Granted, I don't think the company likes the international roaming costs (or maybe I have a global plan, hell i dunno, I just use the bloody crackberry). Although I remember when Erickson said CDMA would never work. They kinda got egg on their face over that one.

I keep with GSM because in Canada or at least in Toronto/GTA, GSM and CDMA are almost the same, you won't even notice a difference. I chose GSM (Rogers exclusive) because I travel to Hong Kong quite often and I need a GSM phone since Hong Kong uses GSM almost exclusively.xboxrulz

In Kenya, where I operates from, there are two Wireless Networks companies that relies on GSM I.e. Celtel Kenya and Safaricom Ltd and one using CDMA I.e. Telkom Wireless. Whenever I used Telkom Wireless service, I get clear service as compared to the two GSM Networks services. I have assumed that may be the two GSM companies have more subscribers hence affects quality of service unless the Telkom Wireless that is slowly scrolling subscribers' space. My assumption is still under test but I assume even though both have dos and cons, I think GSM networks eventually gives the best! Though I wait to be assisted with more information.-Richard Omolo

What standards will be used is depending on country's regulation and frequency regulation. GSM and CDMA run on different range of frequencies. And if a range of frequency is full, then providers will start looking other standard and implement the new standard.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 communicationCDMA : 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.

out of cdma and gsm, i choose gsm.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!


.:Brian:.

I have to say that in the areas I have been (now i am in the US here)....CDMA seems to be better....I mean I have signal almost everywhere that I ever go.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...

I am fascinated by cdma offerings that attracts the rural people but gsm is not so economically attractive BUT major businesses of the city runs on GSM technology.majority of the business outfits runs on gsm..

Xboxrulz doesn't know what he is talking about... CDMA and WCDMA are not at all the same thing. Not only is WCDMA not CDMA, the two technologies are not even compatible. 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 deliveryTechnically 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.-AllC

Using non-Bell phones

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!

I just switched from CDMA to GSM (Verizon to T-Mobile). I chose GSM. It just makes more sense in a world where lots of people are traveling from place to place.I live out in the country, and will be going to college soon in the country, but I've found that with increasing technology, a GSM phone in my hometown has a good signal as does a GSM phone. I've also traveled to Europe and it was a pain not having my phone work while I was there.I was more than happy to switch. The sound quality difference is barely noticeable to me, but hey, it's probably different for others. -feedback by Katherine

I'm in Kenya and here there are both CDMA and GSM networks. The leading GSM company Safaricom intends to upgrade to WCDMA in a while and I'd say CDMA reception here is better and data transfer is better and costs less. GSM reception is fairly good though its pathetic when its time for free calls using Safaricom. The other GSM company Celtel's reception is better and calls are clear all the time though it seems to have more BTS sites (what some may call boosters) generally. With both GSM networks roaming is quite easy to East, Central and South Africa. It seems that WCDMA is the future around here.

Good info - can I have more?

CDMA vs GSM

 

Replying to jerms

May I ask whether you're in a large city or a rural area? And my main concern - how is the voice quality of GSM versus CDMA?

------ ADMIN REPLY -----

GSM

Global System for Mobile Communication. The most widely used current technology for mobile telephony and data communication. GSM systems were originally conceived for voice telephony and provide only very limited bandwidth for data communication. Developed in the early 1980s to allow for roaming throughout Europe.

 

CDMA

Code Division Multiple Access. A digital technology pioneered by QUALCOMM that provides crystal clear voice quality in an exciting new generation of wireless communications products and services. Using digital encoding and "spread spectrum" radio frquency (RF) techniques, CDMA provides much better and cost-effective voice quality, privacy, system capacity, and flexibility than other wireless technologies, along with enhanced services such as short messaging, e-mail and Internet access.

 

CDMA Quality is technology wise is better than GSM.

Rogers is not the only GSM provider in Canada

Nope... FIDO is GSM as well.

Replying to FeedbackerThanks - I'd heard that CDMA is supposed to be superior voice quality, but I've also heard reception sucks for CDMA in large cities - specifically Montreal..Can anyone confirm or argue with this? I'll be moving there soon and my contract with Rogers is almost finished, so I'm thinking of switching to Solo or Telus because their plans are cheaper.

Facts:WCDMA is a 3G for GSM, UMTS is a part of WCDMAEVDO(CDMA2000)is a 3G for CDMA (WCDMA) (CDMA)WCDMA - 70-140 kbps EVDO - 300-700 kbps UMTS - 275�380 kbps WCDMA != CDMA <----- FACT! (WCDMA does not equal CDMA)My thoughts:CDMA > WCDMAUMTS will not rule the world and those history books will remain blank for years to come.If you travel the world GSM is right for you, if you travel the states CDMA is right for you.If you like to get a new phone every month GSM is right for you. If you like to send and receive large amounts of data CDMA is right for you.Verizon has the best coverage, over Sprint (both CDMA) but the software on the phones **** (Verizon)! options: Smartphones; Sprint has coverage in concentrated coverage areas, more people in the target areas.I have both PC cards Sprint and Verizon, Sprint seems to be in more spots I travel, however Verizon seems faster when I can connect to the faster network.AT&T has the best phones! Lowest dropped calls my [explitive]! I have had 6 dropped calls on Verizon, 4 of which in the same area in TN while traveling it is just a bad spot, and 50 million on AT&T. This comes back to the type of network, CDMA hands the call hand off to the next tower much much better. I drive a good distance often, if you are not moble and in one area during most of your conversations dropped calls are a moot point.-reply by Phreay

CDMA has been developed for an isolated society and bases its product on one PERCEIVED need- the need for spped. They have missed the main point of mobile communication- COMMUNICATION and this is what GSM provides! A great GLOBAL communication experience. I am South African, visiting in Canada, and coming from a developing world, I had a few base expectations of maintaining contact with my friends and family in SA and UK through sms's. I was disillusioned to find out that it would cost me a minimum of $35 for access to the network which I would pay $0.10 in South Africa. And what do I get for this? Nothing! A further $10 will give me airtime to that value. For $0.15 I can send and recieve an sms!? which would cost me $0.08 in South Africa (only to send- we don't pay for receiving!!??) and $0.30 to make (and receive!!??) a call which would cost me $0.22 only to receive (so halve it again!!). Oh and I STILL won't be able to send and receive sms from my friends and family in UK and SA. Now that I am using a basic CDMA phone- there are LOTS of other things that I find are better on GSM; like predictive text! T9 word is so 10 years ago!! OK so maybe I have an old phone... But the sim card offers such flexibility and offordability I believe that Americans who dominate the CDMA market are purchasing with their eyes closed. GSM rocks!! and in the gloabal world that we live in GSM has come to the fore- CDMA have developed their technology for an isolated society. I found this article VERY informative about the two types (CDMA and GSM, although it has not been updated to include 3G which I used in SA and it was great!)
