We have tons of wireless data transmission. I'm on a phone rn
Fiber cable use light, which is wireless, but it is contained inside a cable
Fibre cables are also wires.
They are glass tubes that direct light. I dunno if that classifies a wire
Isn't WiFi wireless ?
When you get to high school, it will be explained. High frequency transmission is line of sight. Can you see Europe from NYC? No, then cables are needed.
Or up to satellite and back down, but the limits of that method are beyond this discussion.
