How Does WIFI Signal Penetrate Walls? (Illustration + Analogy)

I explain with cool illustration how we use WIFI in a different room to the router.

I was sitting on the toilet wondering how does the wifi pass through the toilet walls? So I ended up here.

All you need to know is..
wifi to wall is to light to glass.
Some glass is just more tinted than others.

You taught me a world of information in just a few minutes. This is the best explanation I could have asked for.. Thank you, thank you, thank you.

[SurenderSingh-xdkl]

Watched many videos on the topic but didn't understand anything. This is the best video. Thank you.

i get why light cant get through cause of the mosquito example and i get why gama rays and all that stuff can pass through the gaps between the atoms, but i still dont get why can the big radio waves can get through walls, shouldnt they be blocked just like the mosquito example?

[BadCaliph]

Very educational and good info, dude. This is amazing.

[nthamornin]

the dabbing bitmoji character with the dubstep music threw me off but thank you for the explanation 😂

[justguitar]

IDK why I'm watching this but it was very educational and clear. Thanks

Brother of A Amazing another mother. Very clearly explained and spoken. Keep up the good work

Technically, what Badzilla argues here is incorrect. I’m not attacking him, because analogies are meant to build intuition, and I think that is what he is doing. The way that he uses “large” implies a spatial component to the fields in light. Remember, that when you see those charts of light where you have electric fields in one direction, and orthogonal magnetic fields in the other, the height of those fields ARE NOT SPATIAL.

It is not the “smallness” or “largeness” of certain EM frequencies that allows them to pass. Rather, it is the bands of frequencies that the matter in the walls won’t oscillate to. Imagine your friend is on a swing and you (the pusher) is pushing them at a certain rate (frequency) If you push them once every minute (low frequency), they will hardly move. If you push them once every second (high frequency), you will essentially cancel their oscillation out with half of your pushes.

I was lost until you mentioned atoms then it clicked thank you :D

Awesome analogy and great explanation! Keep doing it

[cheontop]

I've been studying basic acoustics & lightings these days, but still don't know how wavelength works until I watch this haha. Thank you!

[nygeek]

2.4ghz and 5ghz refers to frequency, not wavelength. Since the frequency is inversely related to the wavelength, the higher the frequency, the smaller the wavelength, thus why 5ghz WiFi can not penetrate barriers as well as 2.4ghz WiFi bands, even though the higher frequency can transmit faster speeds.

[frosty-tgme]

that actually was a very good analogy and I did learn something new even though I felt like it was right In front of me the whole time

[abdllahalaidaros]

I love the way u explain what we studied .. I feel like I just understand what I learned

[phamjack]

Thanks man, this helped me finding a better position to setup the AP

[ZARC-WOD]

Now I understand this completely thanks bro

[TheApurv]

You are awesome, brother! Thanks for the knowledge.

[XTenDaysX]

You have some great analogies man really helps you understand. Thank you
