Wi-Fi sends messages through the air using radio waves, just like how a phone uses sound to talk to another phone.
Imagine you and your friend are playing with walkie-talkies in the park. When you press the button on yours, it sends a message through the air to your friend's walkie-talkie. That’s similar to what happens with Wi-Fi, but instead of a walkie-talkie, we use routers and devices, like phones or computers.
How It Works
Radio waves are invisible energy that can travel through walls and around corners. A router in your house sends out these radio waves, which carry information like pictures, videos, and messages.
When you use your phone or computer to connect to Wi-Fi, it listens for those radio waves and understands what they’re saying, just like how your friend hears your message on the walkie-talkie.
It's like having a special kind of air message service that works all day long, even when you're not touching anything!
Examples
- A router sends out invisible radio waves that your phone catches to let you stream videos.
- Your laptop uses tiny signals to talk to the Wi-Fi router, like a secret handshake.
- Wi-Fi lets devices in your home share internet without needing cables.
