What type of communication device operates at low power and uses a network of repeater stations?

The most appropriate choice for a communication device that operates at low power and utilizes a network of repeater stations is a cellular telephone. Cellular phones work by transmitting signals over radio waves to nearby cell towers, which serve as repeater stations that boost and relay the signals. This system allows for extensive coverage, enabling communication across long distances by connecting calls through a network of interconnected cells.

Cellular telephones typically operate at a low power level compared to other communication devices, relying on these strategically placed towers to ensure signal clarity and reach. This design also allows for the efficient use of bandwidth and facilitates mobile communication for users on the move, which is a key feature in today’s telecommunications landscape.

In contrast, satellite phones utilize satellites for communication without needing ground-based repeaters, making them suitable for remote areas but not fitting the criteria of low power and reliance on repeaters. Base stations are components of the cellular network that handle communication but are not handheld devices. Two-way radios also provide direct communication but often operate on higher power levels and do not utilize a network of repeaters in the same way that cellular systems do.
