ATTREP's Comment on 3G Networks
For working for AT&T, you must be one of the most uninformed reps. I don't even work for a cell phone company and I know more about the technologies than you do! LOL.
The technology that Sprint and Verizon have delpoyed (CDMA2000 1X EV-DO Rev. A) is a 3G technology! AND it is SO, SO much faster than the EDGE that AT&T has across most of it's network. The 3G technology that AT&T does have deployed is in a very limited number of cities, is actually slower than Sprint and Verizon's, is actually based on CDMA NOT GSM!!!!! (that's why it's called WCDMA, duh), and was actually deployed AFTER Sprint and Verizon's.
Get the facts straight next time. Obviously CDMA is the technology of the future and not GSM. Data speeds are so much faster and ...

Actually, yes CDMA is faster then EDGE, but WCDMA and HSPDA are faster then EV-DO rev A, by almost double.
WCDMA is loosely based on CDMA and that is why companies do not have to pay royalties to Qualcomm, unless the use the Qualcomm chipset.
Also CDMA does not support simultaneous voice and data.
Unfortunately CDMA is not the technology of the future. It's actually being phased out from many areas, Latin America that had 17 countries deployed, are migrating to GSM to make sure that are part of the world standard. CDMA is like BetaMax, better, but loss the race.

I agree. Sprint knows this. And this is why Sprint is going toward wimax. Everyone knew that the GSM carriers here in the states were behind. and that it was gonna take time and alot of money to catch up to the rest of the world. But its comming along. Im ok with waiting and having a world standard instead of going with Verizon , sprint and all the carptastic phones they have i dont care how fast their network is.

Thats not true. I can talk on my Sanyo M1 for Sprint which is CDMA and recieve and send text messages. I do it all the time on conference calls.

Text messages are not the same as data. You can't surf the web on your phone and make a call at the same time, unfortunately. It isn't the limitation of the technology though, it is only the implementation. CDMA is very capable of doing both and EV-DO Rev. A is supposed to be what would allow it without sacrificing any voice quality.

Wow, don't talk.
Yes Verizon and Sprint have a 3G technology deployed, but EDGE is also 3G. HSDPA is much faster than EDGE which is why they are deploying it.
WCDMA is only based on CDMA because it is packet based, but it is still a GSM technolgy.
And how is CDMA the technology of the future when WiMax is on the horizon for Sprint?

EDGE is not 3G. Check your facts. EDGE is 2.5G. UMTS is 3G.
...
OK...so this is most likely a dumb question - can a phone be updated say like thru a sync with Itunes in this case with better technology like 3G? Or, is this a hardware issue too?
Thanks.
Thanks.

It is both. A phone like the iPhone can't be upgraded to HSDPA because that radio wasn't included in the hardware (we know this because of FCC documentation).
Now if the iPhone had come with HSDPA, just not enabled, it could have been enabled whenever AT&T and Apple decided to update the software. We have seen and example of this with the Audiovox 6600 and Verizon when it released without EV-DO and was later updated to have EV-DO support.

I wouldn't call it a joke, but it is one persons opinion.
I do honestly think that CDMA has the edge in voice quality with current implementation and codecs, but that could be fixed anytime by allocating a little more bandwidth and tweaking the GSM codecs.
