I don't know specifically about wifi but, check out EME bounces. With a hand held ham radio on the 6M band and a directional antenna made from like $6 of supplies from your local hardware store, you can have a radio that can bounce a signal off the moon and talk to someone on the other side of the earth.

It’s more like the 2m and 70cm bands, and really big expensive antennas. You can bounce signals off of meteor trails with a cheap antenna and 6m radios, though!

Been out of it awhile so i was thinking 6m, mighta gotten mixed with the scatter-e propagation. But I knew a guy down in San Diego who used to do EME bounces with cheap directional antennas he homemade. But that guy was also an EE at Qualcomm there.

But that was 6 years ago and since I've moved up to Oregon, I havnt gotten to do much ham stuff because I could never hit the repeaters around here. Maybe they are no longer up, maybe its all the hills and volcanic rock?

You can make it work with normal human antennas, as long as the other person has the big ones! I could never contact someone with the same antenna and radio as me via the MOON, but I can on certain days be heard by those big dogs!

Meteor scatter is pretty fun though!
