Question

Which of the following terms best describes a device that picks up signals from​ lower-power radio units and retransmits at a higher​ power?

A. Repeater
B. Mobile radio
C. Cell phone
D. Base station

Answer 1

A Repeater is the device that picks up lower-power signals and retransmits them at a higher power to extend communication range.

Step-by-step explanation:

The term that best describes a device that picks up signals from lower-power radio units and retransmits them at a higher power is a Repeater. Repeaters are utilized in radio communication networks to extend the range of communication by amplifying signals that might otherwise be too weak to transmit over long distances. These devices receive a signal on one frequency and retransmit it on another frequency at a higher power, ensuring the signal can cover greater distances without degradation.
