How does Wi-Fi transmit data wirelessly around us?

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!
