How does a repeater function in a telecom network?

A repeater functions by amplifying and retransmitting signals to extend coverage within a telecom network. Its primary role is to receive weak or degraded signals, boost their strength, and then send them out again. This is particularly crucial in areas where the original signal may struggle to reach due to distance, obstacles, or interference.

By enhancing the signal, repeaters ensure that communication can occur seamlessly across larger distances without significant loss of quality, which is essential for maintaining connectivity in various environments, especially in rural or obstructed areas. This is why the amplification and retransmission of signals is a vital function of a repeater in the telecom network.

On the other hand, options that mention generating signals, controlling data packet routing, or serving as backups focus on other functionalities in telecommunications that do not align with the core purpose of a repeater. Generating signals pertains more to transmission towers or base stations, while routing data packets is the function of routers and similar devices. Backup systems play a different role, typically linked to redundancy and disaster recovery strategies in network design.
