Okay kiddo, let me explain what skywave mobile communication is in a way that's easy for you to understand.
When you want to talk to someone who is far away, you can use something called a radio. A radio sends out signals that go through the air to a special antenna that the other person is listening to.
But sometimes, the person you want to talk to is really far away, like on the other side of the world. That's where skywave mobile communication comes in!
Skywave communication is when you send out signals from your radio, but instead of just going through the air to the other person's antenna, they actually bounce off something high up in the sky called the ionosphere. It's like bouncing a ball off a wall!
When the signals bounce off the ionosphere, they can travel really far, even across oceans! That's how people on ships or airplanes can talk to people on land, or how soldiers in faraway countries can talk to their families back home.
So, skywave mobile communication is just using special radio signals that can bounce off the top of the atmosphere to talk to people far away. Pretty cool, huh?
