Repeaters increase the what for portable, mobile, or base station radios that otherwise could not communicate with one another?

• A. signal strength
• B. effective communications coverage area
• C. battery life
• D. latency

Answer: (B)

Repeaters are used to extend the geographic reach of a radio system. By receiving a signal from one radio and retransmitting it at higher power (often on a different frequency) from a location with better line-of-sight or less obstruction, they bridge gaps between radios that can’t hear each other directly. That expanded reach is what increases the effective communications coverage area, allowing portable, mobile, or base station radios to communicate over a larger area than they could on their own. While repeaters do help signals travel farther, they don’t inherently improve a user’s own battery life or the radio’s internal signal strength in a way that would be noticeable to the handheld device. They also introduce only a small, typically negligible amount of additional delay, so latency isn’t the primary benefit.
