It has to be high frequency, and of course there are regulations there too, so it would be hard.
But if the internet 2.0 would be decentralized the signal doesn't have to be long, if everyone around you is an internet server, the most the signal has to travel is a few meters. It would be doable, but the ISP lobby and governments would not like it.
Great idea, but it seems a lot like a "all or nothing"-solution. That is, you have to get everyone on board first in order to have a network of antennas big enough to work.
Possibly something that Steemit could recommend to people once they reach a billion users. :)
Possibly. Steemit will play a role in it, that is true.
i heard long ago someone talk of this very possibility, seems like a perfect plan to me !! ; - )
