How Wi‑Fi Sends Internet Through Air

Your internet is literally just invisible radio waves blasting through your house right now.

It feels like magic, but Wi-Fi actually works exactly like a car radio or Bluetooth. Your router beams

these waves out into the air, and your phone catches them to translate digital codes into

the videos you watch instantly. We actually have some Australian researchers from

the nineties to thank for this because they wanted to stop tripping over cables. So basically,

the entire internet is just floating around your room waiting for you to grab it out of

thin air.
