Why are coaxial cables no longer used by the ethernet?

What may be active at one time will be likely replaced in the future as technology advances. Coaxial cable is a type of copper cable with a metal shield and other components engineered to block signal interference. The cable TV companies connect their satellite antennae with it to service homes and businesses. Coaxial cables are expensive, fat, and stiff.

This makes it capable of multiple bands of communication, which isn’t necessary for handling network traffic. Hence, it’s a better option to use a solid cable with a single piece of copper for the electrical conductor.
