How does Wi-Fi transmit data wirelessly in your home?

Wi-Fi sends messages through the air in your house, just like talking on a walkie-talkie.

Imagine your router is like a loudspeaker at a party, and your smartphone or tablet is like someone listening from across the room. The router shouts out messages using invisible waves called radio signals, and your device hears them clearly even if it’s far away.

The router takes the data, like pictures, videos, or messages, and turns them into tiny signals that travel through the air. These signals are like invisible bubbles floating from one place to another.

Your phone or tablet has a special part called a receiver, which catches those bubbles and changes them back into data you can see or use. It’s like when someone speaks in a whisper, and you hear it clearly even if they’re far away, except the router is shouting messages that your device understands perfectly!

When you're watching videos or playing games on your phone, the router keeps sending more bubbles of information so your screen stays bright and fun!
