"A couple of weeks ago I received a call from one of my start-up companies gearing up for an exhibition and demo that was dependent on having online connectivity.
Unfortunately, the location was at a marina some 500 metres from the nearest wi-fi hotspot and no 3G signal was visible. They wanted to know whether I could help.
In my lab I looked out a couple of old wireless routers and a wi-fi extender plus a wi-fi dongle. About an hour later I was able to get four bars at 200 metres and began to get confident that this was going to be an easy fix.
To get the final throw I needed to focus the energy in a beam and enlisted the help of an old domestic satellite dish and a dongle. The rough and ready set-up is shown below." ~networks.silicon.com
