Basically the swedish operators have more frequencies available to them 
than the US ones, and the country is more sparsely populated. Especially 
the 20Mhz available per operator in 2600MHz makes a huge difference. Even 
initial deployment of 4G in Sweden meant one was able to regularily get 80 
megabit/s of download speed. Now with a lot of users this is of course 
less, but sometimes if you're alone in the cell you can still get this. 
I'm actually surprised that they only get 8 up, usually much more up speed 
should be possible.
