The ComputerClubsCamp2012 needed an internet connection. IPoP (IP over carrier Pigeon) and laser links were discussed, but practicality prevailed and [BOB] organised a couple of 3G dongles.
In brief, put power and ethernet up a 6m pole, connect to a router with USB dongle and plug that in to a 11dB directional Yagi antenna. What could go wrong.
List of people involved
[BOB] provided the router and 3G USB dongle(s).
[DTK] built the enclosure and mast.
