What role do repeaters play in a telecommunications network?

Repeaters play a critical role in telecommunications networks by amplifying and retransmitting signals. In the context of telecommunications, a repeater is a device that receives a weak or degraded signal and then boosts its strength before sending it out again. This is especially important in long-distance communications, where signals can weaken as they travel over distances and through various media. By amplifying the signal, repeaters help to maintain the integrity and quality of the transmitted data over longer distances, ensuring that it can be effectively received at its intended destination.

The specific functionality of repeaters makes them essential in scenarios where direct communication between devices is not feasible due to distance or obstacles. They enable a network to cover larger areas without a loss of signal quality, thus enhancing overall network performance by extending the range and reliability of communications.
