This was the first site we installed,
Oaklands Caravan Park in Warton, Lancashire
as you can see from the image below it is a simple relay from the higher node, which currently has one user on it, to the lower node which is connected to a standard ADSL router (Also use 3G or Cable Systems Too) and supplies the higher node with internet. These routers are connected to 2 Hi-Gain antennas, the higher one connected to an 15dbi antenna and the lower one an 8dbi antenna which provides coverage to the entire site.
