Also, when can we get Internet over Radio? Good luck stopping waves bouncing off the stratosphere. Such a tech would immediately end censorship and lawfare using physics and science.

Mesh networks have been made using ham radios! It's not ready for the general public since you need a ham operators lisence & their range is limited by line of sight. But if you own a large property, you can network your own space using the tech. It's also a good back up in the case of a large scale infrastructure disruption.

Heres a link :)

Are there any papers or sources on this? Of course it would be very slow, but I'd be interested to see what proposals exist.

I'm aware of 802.11 lol, But i'm wondering about papers or sources talking about the feasibility/usability of bouncing it off of the ionosphere using something like shortwave to achieve the objective originally stated.

What makes 802.11 effective is that it exists in the GHz band and as a result it can move a lot of data very quickly, but you need a low frequency to allow a radio signal to be reflected back to earth without escaping into space instead, so speeds would suffer greatly. Just wondering if there are proposals on how to make it usable in the low frequency bands so that you could reflect it back to earth and also not have to wait 7 years for an image to load.

Furthermore for this to work you would need a relatively high powered radio setup on your end to send messages back to the source youre receiving from if you don't intend to just receive data.

:D

I'll see if i can find something specifically about what you are asking, but I would be surprised if anyone has taken the time to try to bounce WiFi. The wavelength might not be amenable to bouncing, as it is such a high frequency signal. If I recall correctly, there is a relatively narrow range of wavelength that will actually bounce back to earth off of the atmosphere.

Awesome, this is just what i was looking for, thanks!
