What term refers to a wireless device that receives an incoming signal and automatically responds?

Explanation:
Transponder. The idea here is an automatic reply to what it receives. A transponder is designed to receive a signal and then immediately generate a predefined response or perform a specific action without human input. That automatic response is what sets it apart from the other devices: a transmitter only sends signals, a receiver only receives, and a repeater simply relays what it gets to extend range (without generating an automatic, context-specific reply). In many systems like RFID or satellite communications, the device that responds to an incoming signal is called a transponder.
