The OLPC France association will bring wifi to its Nosy Komba
(Madagascar) deployment this way in June [1], packing antennas,
routers, solar panels, batteries and masts in trunks (!) and setting
them up with local help through line of site wifi over 11km from an
xDSL connection on the nearby larger island of Nosy Be directly to the
XS school server in the school compound. This will be the first
Internet connection on Nosy Komba Island.

Bastien will be with you to tell you more about Nosy Komba ;-)
