Not so Mark, 3G is a CDMA based system, so it will be possible to
achieve good coverage in rural areas with very large cells.
It won't have the cell size restriction of GSM.
No, 3G is a marketing term given to a group of technologies which
overlay services over relatively high-bandwidth mobile communications
channels.
EVDO is essentially 3G over CDMA. 3GSM is 3G over GSM. They're not
the same. Telstra has picked 3GSM for its future rollout plans.
3G is indeed a CDMA system. WCDMA in fact & is totally different to GSM
( & CDMA ;-)
No, Don, it isn't.
3G means "3rd Generation."
First generation cellular: AMPS.
Second generation cellular: GSM and CDMA: Digital cellular with
low-bandwidth data channels.
Third generation cellular: 3GSM, EVDO, WCDMA, and no doubt others
I haven't heard of. Digital cellular with high-bandwidth data
channels. Hyped by companies like "3". Amazingly expensive because
the spectrum auction yielded dot-com prices instead of realistic
prices (not a phenomenon unique to Australia. World-wide takeup
rates have been low due to pricing constraints imposed by spectrum
costs, with some notable exceptions like Japan, where this stuff is
ubiquitious)
Fourth generation cellular: Undefined at the moment, so virtually
every mobile technology vendor and network operator claims that their
gear is 4G.
