Why are repeater stations needed for long distance communication?

Answer 1

Any signal that you send out is going to be weaker as you get farther away from it.

As you move away from the source of the signal, eventually you reach a distance

where the signal is the weakest that you can possibly receive, and if you go any

farther, you won't be able to receive it at all. That distance is the maximum possible

range of communication. If you want or need to communicate any farther than that,

you'd better put in a repeater station. It receives the original signal, and re-transmits

it again, so that you can move farther away and still hear it.

Answer 2

Repeater stations are needed for long distance communication because the signal strength of a radio, television, or telephone transmission weakens as it travels over long distances. Repeater stations amplify the signal, allowing it to travel farther before it weakens to an unusable level. They are strategically placed along the communication path to ensure reliable and uninterrupted transmission over long distances.
