I do know that some cdma carriers in canada are planning to switch to gsm.
My gsm phone gets signals where cdma does not. gsm has much more coverage than cdma in the us and goes through walls a lot better. Having to call people on verizon sucks when they are indoors.

But really each technology will be better/worse in different areas. I won't repeat my last example but choose which provider is good in your area and use them. |

Obviously since you live in Canada you are unqualified to talk about what happens here in the US, so let me educate you.
Fact - coverage has nothing to do with CDMA vs GSM. However, those on the Verizon network have substantially more coverage in many areas than those on AT&T or T-Mobile. Since Sprint users can roam on verizon, they have that too.
In areas I primarily travel, i.e. the Eastern Seaboard of the US, Verizon wins hands down in terms of coverage. However, I find that with a weak signal I can still make a call on Verizon's CDMA network and have people understand me. On GSM when the signal is low, people sound like they're underwater and it goes rapidly downhill from there.
CDMA is also more spectrum efficient. GSM's old standard was based on TDMA, which allocates time slices for each user. CDMA has them all transmitting at once which makes more efficient use of spectrum since they're really not taking turns like on CDMA. |

Nope, sorry you are wrong there. As for GSM penetrating walls better, that is debatable, but I find the claim dubious at best. IMO any difference in wall penetration between the technologies would be negligible. |

IMO any difference in wall penetration between the technologies would be negligible. I am right I have GSM and my girlfriend has CDMA. She looses signal in her house. I get perfect signal. She loses signal cross country in remote areas, I do not. She has gone through 3 phones and it does not make a difference.
Anywhere she has a signal I do, but the CDMA phone does not get a signal everywhere GSM does.
I am sorry, but between seattle, chicago, new york, florida, texas, louisiana GSM has better coverage than CDMA.

Fact - GSM gets more coverage across the US, I know I have driven across the US many times.
Fact - weak signals are terrible on CDMA
Fact - when you are in a highly populated area CDMA calls quality drops because the tower lowers call quality to take on more calls.
Fact - GSM gets a much better connection in low signal.
Fact - GSM gets better coverage from New York all the way to florida ( I have driven it with both CDMA and GSM phones)
Fact - I have never had a call on my GSM phone sound like it is underwater. Now I know you are lying. This is possible on CDMA since the tower will lower quality as more people connect to the tower.
Fact - I have lived in Indiana, Louisiana, and Florida. I am in Canada for work. Sorry to ruin your Canada bashing fun.
In Canada the CDMA providers are looking into switching to GSM.

W-CDMA and CDMA are not even close to the same thing.
W-CDMA is closer to GSM than CDMA2000.
Phones that use W-CDMA will also work on GSM as a fallback to where W-CDMA is not running.

Fortunately, AT&T is migrating to LTE which uses OFDM, not UMTS. |

maybe ur gf is using those small cdma companies? i.e. metropcs and others.
Myself having gone through every single carrier and working in cellphone business will stay in CDMA and Verizon is by far the best. Also that depends how much money each company invest money in their towers and Verizon is by far the one who spend the most. |

I guess Verizon wasted their money because they did not optimize their towers to get better coverage than GSM.

I've never called someone on AT&T that the call quality doesn't suck, or get dropped. Landlines/Voip/CDMA calls are crystal clear. I don't know which way you're driving, but I drive from The middle of WV to Orlando all the time and the only time I have less than 5 bars is going through the 2 mile tunnel into VA, and even then I DONT DROP THE CALL, when any passenger with me with ATT looses signal.
FACT- All you're facts are based on YOUR opinion.
Edit-Not to mention the GSM interference with any audio equipment when the phone is about to ring, or is processing a lot of data. |

Well you will believe what you wish to believe and that's fine, but as a whole CDMA has more coverage in the US than GSM. VZW has more coverage than any single GSM carrier including at&t. |
