How does Wi-Fi transmit internet signals through the air?

Wi-Fi sends internet signals through the air like a radio sends music to your car.

Imagine you have a remote control that can send messages to another person across the room, without touching them or shouting. That's kind of how Wi-Fi works! Your router, which is like a smart speaker in your house, talks to your phone or computer using something called radio waves.

Your router takes the internet, think of it as a big stream of information, and turns it into tiny invisible messages that travel through the air. These messages are like little notes being passed between friends in class.

Your phone or computer has a special part called a Wi-Fi receiver, which listens for these messages. When it gets them, it changes them back into something you can use, like pictures on your screen or music coming out of your headphones.

These messages are sent using radio waves, the same kind that make your radio work! Your router sends out a signal, and your phone catches it. It's like having a special walkie-talkie that never stops talking, but you can hear it from anywhere in your house.
