What is the purpose of using 'repeaters' in communication networks?

Using repeaters in communication networks serves the key function of amplifying and extending the range of radio signals. When radio signals are transmitted over long distances, they may weaken due to various factors such as terrain, obstacles, and distance. Repeaters receive these weakened signals and amplify them, allowing the signals to be retransmitted with increased strength. This process ensures clearer communication over greater distances, enhancing the coverage area of the communication network.

The primary role of repeaters is to maintain the integrity of the signal and improve the quality of communication, particularly in environments where signals might otherwise degrade. This makes them essential components in both analog and digital communication systems, particularly in scenarios involving vast geographical areas or urban environments with many obstructions. As a result, networks can achieve more extensive coverage, connecting users who are situated further apart.
