3G(WCDMA, UMTS/HSDPA) question
I'm so confused. Ok 3G phones will be here in January...an LG and a Samsung for starters. The first to are only WCDMA/Umts, what is the HSDPA...different technologies, different speeds? Also...i know i posted this b4 but will the first phones be ptt able phones...they better be. I can't stand the way cingy does things...i have several ppl that agree w/ me that cingular's first two plane-jane ptt phones are stupid....no camera or nothing. My prediction is that the 3G phones will be the same...they may have a nice camera and fast download speeds...but they will leave off ptt....um how about a phone that can do everything people want??

ok so will HSDPA/UMTS/WCDMA eventually take over GSM...or is it just somethign extra. b/c the new 3G lg phone & samnsung zx-10 will be gsm and wcdma?

HSDPA is to UMTS as EDGE is to GPRS. you will need a phone with HSDPA to take advantage of the faster speeds. I think, and i'm sure someone will say if i'm wrong, WCDMA is the key in the 3G tech. Eventually, when there are enough towers to have the same coverage as GSM, yes WCDMA will replace GSM.

Nothing wrong with that. Perfect explanation.
