Sure, why not? Long ago we used to bounce signals off the ionosphere.
So if all the angles and paths are just right, what you wrote can happen.
Craziest thing I ever seen.
I extended my internet via ethernet 12 floors away, Yes I ran cat5e 12 floors, 100m cat5e, then connected an Access Point (wifi name Jingle)
I am on 10th floor and Access Point is on 22nd.
Crazy thing is I can get Jingle(22nd floor AP) from 10th floor. That's 12 floors away Jingle wifi is working.
Is this possible? I am seeing it so possible but how can this be?
I don;t know if this has anything to do but I used about 70m cat5e, so 25m+ is wrapped next to ethernet switch in 10th floor,
Could this wrapped cat5e sending Jingle wifi to 10th floor?
I wouldn;t think so but who knows?
