What device handles both transmitting and receiving radio signals?

• A. Repeater
• B. Amplifier
• C. Transceiver
• D. Receiver

Answer: (C)

A transceiver is a device that handles both transmitting and receiving radio signals. It combines a transmitter and a receiver in one unit, enabling two-way communication without needing separate hardware for sending and receiving. In drone systems, the remote controller and the drone rely on transceivers to exchange information: the controller sends control commands and the drone replies with telemetry, video, and status data.

An amplifier simply boosts the strength of a signal and doesn’t provide the receiving path. A receiver only listens and cannot transmit. A repeater does both receive and retransmit to extend range, but the term that describes a single device capable of both transmit and receive as its primary function is transceiver.
