A repeater receives the information over one input or frequency, and retransmits the same information via a separate output or frequency (basically sending a copy). A regenerator actually rebuilds the original signal and sends it on its way.
Signals drop in strength over distance just as sound does due to loss measured in either voltage or DB. The more powerful the transmitted signal, the further it can travel before needing a boost. Single-mode fiber optic cables have very little signal loss for hard line communications.

The original way to assure signal strength at the receiving end was to install amplifiers (repeaters) along the route. This is OK over moderate distances. The problem was that some noise was introduced along the way, and it got amplified too. Regenerators pass on only the original sounds.

properly, i do no longer comprehend what a "regenerr" is, yet a repeater gets transmissions, amplifies them, and then retransmits them so a sign can conceal longer distances. Say you're on your automobile on one side of a mountain. you have an beginner radio. there's a repeater on the best of the mountain. You communicate on your beginner radio on the repeater's enter frequency. The repeater will increase your transmission, and then deliver it back out on it rather is output frequency - so now, you are able to confer with people on the different side of the mountain.

Without them the signal will not reach it's destination. Another good thing about a repeater is it can greatly extend the range of a hand-held radio.
