I'd like to set up a wifi connection between two houses that are roughly 2 1/2 blocks away. Right now I'm assuming it might have to go through a few trees. I'll check on the roof when the weather permits to see if I can get direct line of sight.
Is there a solution that doesn't cost thousands of dollars (and is legal).
What about alternate wireless transmissions. They use to use shortwave radio for tcp/ip. I'm guessing this isn't practical given the speeds would be ridiculously slow.
