Scientific American "What Is 5G?"
I read about 5G. 5G is a new telecommunicating system using very short radio spectrums. We can use this for many things. And it will make our lives more convenient. First, there are various products embedded, such as sensors of vehicles medical machinery. They are connected by 5G, there is not any lag. So we can operate vehicles very precisely. Second, we can use sidelinking system. The Sidelinking system will allow self-driving cars to coordinate more efficiently by communicating with each other directly. So we can prevent traffic jams.
