How does Wi-Fi transmit internet signals wirelessly?

Wi-Fi sends internet signals through the air using radio waves, just like a phone uses sound waves to talk.

Imagine you and your friend are playing a game with flashlights in a dark room. When you shine your flashlight, your friend sees it and knows to do something, like turn on their own flashlight or say “got it!” That’s kind of how Wi-Fi works. Your Wi-Fi router is like the person with the flashlight, sending out messages through the air.

The router uses radio waves, which are invisible signals that can pass through walls and around corners. These waves carry information, like your favorite video or a game you're playing, to your device, such as a phone or computer. Your device picks up those signals, just like your friend sees the flashlight beam.

Wi-Fi keeps sending messages back and forth, like how you and your friend keep flashing lights to each other. This way, you can watch videos, chat with friends, or play games, all without any wires!
