We're getting a bit pedantic here - both 3G and Next G are 3rd-generation mobile phone networks using similar technology.
2G is the old GSM technology.
3G operates in the 2GHz band. Next G is a slightly later technology than 3G, and (in Telstra's case) operates in the 850Mhz band.
Both sytems use variants of Wideband CDMA technolgoy, totally different to the older 2G GSM and significantly advanced from the older CDMA.
The technology has nothing to do with the spectrum it occupies.
Telstra chose that spectrum because
a) it already owned the license to the exclusion of others
b) the lower frequency compared with 3G ensures a better range
A downside with their choice of band is that there were not many manufacturers of the handsets in the 850MHz band (Cingular in the US was about the only other operator at the time of Next G implementation).
And of course, Australia is fairly unique with cellular mobile systems in that we push extreme distances from our cells, which was never a consideration with Europe and US operators. So with some of the early handsets, sensitivity was not really a consideration, an issue Telstra should not have disregarded.
