I genuinely have no idea. addictanon seems to know his stuff, but as far as wifi goes and that, I wouldn't know. It's never been mandatory or part of my courses, and I prefer to not know of these things since they are far too complex. I can do calculus, but not this shit. Wavelengths and hertz do my head in, so I apologise for not being intelligent enough in this respect to know.

Nice reply you stupid mother fucker. You should give up that name and be noexplain.

Ohh, I used to live off of the anon hate. It dulled down, but I just can't wrap my head around the fact that people can't accept that I have gaps in my knowledge. It's kinda hard to study all 3 core sciences at a high academic level without shelling out thousands in student loans.

When they have to ask someone for an answer, I kinda feel like they have to right to be upset when you don't know. They sure as hell didn't know and your services are volunteered. When they start paying you to know everything, then they can genuinely be upset. Otherwise it's childish. Lmao. But such is life on the internet.

Question is ill-posed, sound and wifi work over roughly the same wavelength ranges.
2.6Ghz wireless-b router => c/2.6Ghz = 11.5cm
speed of sound is 343m/s and sound is audible between ~20Hz-20kHz => 343m/s / 20Hz-20kHz = 17m-17mm
I can tell you the creator was specifically modeling WiFi though.

Doing some more research, the creator was indeed mapping wifi. The reason it looks so much like a sound simulation is because, according to the article, he used a refractive index of 1 for the empty space and a "very high" refractive index for the walls. Who knows how accurate it is, and the material of the walls (concrete, brick, drywall, plaster) makes a big difference.
So it is wifi, but it's of questionable accuracy. I'd love to see some experimental work done to try to verify his equation and the variables he used. Could be very interesting.

It's based on small radio waves they work like the satellites on roof.
