How does Wi-Fi technology transmit data through the air?

Wi-Fi sends messages through the air using radio waves, just like a phone call uses sound waves.

Imagine you and your friend are playing a game where you send secret messages by tapping on a table. If you tap fast, it means "yes," and if you tap slow, it means "no." Wi-Fi works kind of like that, but instead of taps, it uses radio waves, invisible signals that can travel through the air.

Your phone or computer has a special part called a Wi-Fi adapter, which acts like a radio. When you open a website or watch a video, your device sends out signals in the form of waves, just like how a radio station sends music to your car radio.

These waves travel through the air until they reach your router, like a special kind of radio that catches the signal and passes it along to the internet. Then, the internet sends the message back to you using the same kind of invisible waves.

Your device breaks up big messages into small pieces, just like how you might break a big puzzle into smaller parts to carry them one by one. Each piece is sent as a wave, and your router puts them all together again so you can watch that video or play that game without interruption!
