> huge Wifi antenna to connect to an open Wifi of a rural school a couple of kilometers away

That's impressive, but how did this work from the school's side? Wouldn't they need a huge wifi antenna too?

"huge" antennas usually have high gain, which increases your signal-to-noise ratio - both Rx and Tx.

So one can "hear" signals further away and "speak" softer than would.be normally necessary.

They had regular wifi access points, nothing fancy.

The huge antenna [1] was connected to an Alfa R36 hotspot which was fairly powerful. I guess that's why it worked.
