Austria: Orange's Datenpaket

[inquisitor]

The Netherlands are flat as a pannekoek and densely populated, which makes it easy and economical to cover the whole country and in Sweden they have UMTS running also at 900MHz, which provides up to four times higher signal range (and in terms of covered area you have an even stronger effect as the covered area results from the range (r) squared and multiplied by π resulting in a roughly 16 times larger area covered; covered surface = πr²) than UMTS at 2100 MHz and so makes it pretty easy and cost-efficient to provide nationwide UMTS coverage, since you theoretically need only one-sxiteenth of basestations to cover the same area.
But of course Austria has traditionally been a leading nation in cellular technology and were one of the first to roll out UMTS, later HSPA and then HSPA+, so my objections of UMTS-dead zones may be exaggerated.
