My father actually worked for a startup providing wireless access to rural and urban areas back in the late 90s. It was nice to have a 27 megabit connection to my house when the hottest thing was a 2 megabit DSL line.

What cost that company $200,000 in 1998 and took up an entire rack now can be bought for about $2,000 from Ubiquiti and mounted in a few U in a rack. They even have the software available to run your own ISP!
