How does Wi-Fi transmit data wirelessly from your router?

Wi-Fi sends data from your router to your phone or tablet using invisible waves, just like how a radio plays music through the air.

Imagine your router is like a loudspeaker at a party, and your phone is like someone listening across the room. The speaker doesn’t need wires, it just makes sound waves that travel through the air, and your ears pick them up. That’s what your router does, but instead of sound waves, it uses radio waves.

How it works

Your router takes the data you're trying to send, like a message or a video, and turns it into radio waves, which are invisible vibrations in the air. These waves travel through the room (or even your house) until they reach your phone or tablet, which acts like a little radio receiver.

Your phone then changes those waves back into data you can use, like letters on a screen or music playing from your device. It’s like turning sound waves back into words when you listen to a radio!

Every time you click a link or watch a video online, the router is sending out invisible messages that your phone catches and understands. No wires needed, just waves!
