Packet radio
Packet radio is like sending messages through a secret code that only special radios can understand. Instead of talking like normal, you type your message into a computer or other device, and it gets turned into lots of tiny pieces called "packets". These packets are sent over the airwaves to the special radios that can decode them back into your message.
It's kind of like sending a puzzle over the airwaves - each packet is like one piece of the puzzle, and when all the packets arrive, they can be put back together to make the whole picture (or message). The special radios that can decode the packets are called "packet modems", and they can understand the secret code that the packets are in.
Packet radio is really useful for people who want to send messages over long distances, like from one country to another, without using the internet or phone lines. It's also useful for people who like to communicate with each other using cool technology!
