How does Wi-Fi transmit data wirelessly throughout our homes?

Wi-Fi sends data through the air like a radio sending music to your phone.

Imagine you have a speaker in one room and a pair of headphones in another. When the speaker plays music, the sound waves travel through the air, and your headphones pick them up so you can hear the music. That’s kind of how Wi-Fi works, instead of sound waves, it uses radio waves, which are like invisible messages that move quickly through the air.

Your router is like a special speaker that sends out these radio messages. Your phone, tablet, or computer is like a receiver that listens for those messages and turns them into things you can use, like videos, games, or messages from friends.

Every time you click on a link or send a picture, your device talks to the router using these invisible radio waves, just like how your headphones listen to music from a speaker. This back-and-forth conversation happens super fast so you don’t even notice it!
