This year I learned from a college classmate about WUGs. Basically, a group of people create a wireless network over a (relatively) small geographic area like a city. These are created using Wi-Fi hardware operating at certain license-free frequencies. They can be used for internet access or to simply play networked games. I suppose some are used as intranets as well. It all sounds a bit much for me as a networking newbie to set up on his own, but it does sound fun; and who doesn't love free internet? For those looking for more information, here is what I could find off google: http://news.sabinet.co.za/2009/09/03/wireless-user-groups/ https://en.wikipedia.org/wiki/Wireless_user_group The Cape Town WUG has its own wiki where they explain the basics. I'm assuming most users here are obviously not from Cape Town so I won't link it here so as to not seem like I'm advertising.
