Building wide WiFi is not something the FCC really regulates. They put some standards on manufacturers to comply with but beyond that there is no interaction at the user level.
Because they manage the fees paid for telecommunication services to be provided to areas where it's less profitable but necessary.
The thing is, the Internet is real. And the modern day student NEEDS access to the internet. But an alarming number of them only get access to it via the "free" hotspots at McDonalds and such - and kids needing to do homework, that's an issue. I mean, you'd think they'd go to the library to do their work and use their wifi, but no, they close at 6pm, so they move to the local McD's because they have WiFi for free.
The parents can afford a computer (they're not THAT expensive these days). but can't afford internet access, so instead of kids having to trudge through the city seeking free internet, why not provide funding for schools and libraries to offer it up so kids can use it.
Sure, it works fine in the city, but when you're out in the boonies, well, wifi may be least of a town's concern and the kids just have to find a local hotspot. Having it be their library and school, can only help matters
