This statement is true. Repeaters operate at the physical layer (Layer 1) of the OSI model. They receive signals and regenerate them to their original strength before transmitting them further. This allows signals to travel over longer distances without degradation, helping maintain network performance across extended reaches. It is important to distinguish repeaters from amplifiers, as repeaters do not merely amplify but also regenerate the signal to prevent the propagation of noise.
