Found an (old) but VERY INTERESTING news about wi-fi bridges.
http://www.wimax-italia.it/2007/05/30/il-wi-fi-fa-paura-al-wimax/
For the ones that does not speak italian here is the translation of
the most important part: (made by me so sorry for mistakes)
Made by teachers and studens from Politecnico di Torino (Engeneering
faculty): a stable 300km Wi-Fi (NOT WI-MAX) bridge at 20 Mbps using 2
dismissed antennae and some old 386 PC running an old linux
distribution....
Hope this sounds interesting....
