Sweden doesn't have any mountains. Well they pretend they do, but being from NZ, even Kebnekaise is "a bit of a hill" to me
(I should probably hide from the real Swedes now for saying that).
Sweden has a govt policy to provide broadband (defined as 2Mb or better bandwidth) to every permanent house. In a lot of places, it's turned out cheaper to chain cell masts and use 4G even for household broadband in order to reach that, than to lay or upgrade landlines. About 2 years ago my mother-in-law went from having to drive 30km to work to get texts from my kids on her cell, to having full speed 4G at her house out in the middle of a forest, about 2 years ago. Was a bit mindblowing!
