I want to set up a free public internet, I believe it's called point to point or fixed wireless ? little help?

I just want to set up a simple sever with like 4-8tb capacity, fill it up with open source software and music/videos that are no longer under copyright and be able to share it. Of course I realize this will only reach a limited amount of people (a hundred?).. but it's a start.

Could someone point me in the right direction in terms of reading material ? Thanks.
