Guys i live in a very small city, almost a village and i want to make a wireless network with my friends. Our houses aren't further than 2.5 km each other. The only problem is that i can't see my any house of my friends there are other houses on the way. Another friend of mine told me that with a multi-directional antenna we could connect, but i don't believe. I thought that the antennas should see each other. Am i right? Can i connect in some way with my friends?? Always wireless.
