If your aim is to provide broadband to all, you'll have to build there too. Sweden aims to do 100 Mbps to 90% of the population by 2020. Can't do that by just covering urban areas.
That's a fair point.
> And even then, it's much less expensive to connect two dense urban areas at either end of a 100 mile road than to serve sparse suburbs and exurbs along a 100 mile stretch of road.
Not necessarily. Build costs in dense urban areas are high, but there are more subscribers. Suburbs and exurbs are cheaper to build per mile, but have less customers. It averages out fairly well.
Looking at the map, the northernmost county has barely any HSPA coverage. Nevertheless that county has a population of a quarter of a million inhabitants. To get 99.6% coverage, you'd still have to cover over 200 000 of those and everybody else in the country. That's clearly impossible as 100 000 inhabitants in that county live outside the ten largest "metro" areas.
There's just no way of not covering a lot of roads if if you aim for coverage in the high nineties with such a dispersed population.
