Which term describes interference in the radio frequency spectrum?

• A. Antenna Gain
• B. Wave Propagation
• C. Radio Frequency Interference
• D. Transceiver

Answer: (C)

Radio Frequency Interference is the term used for disturbances that degrade signals within the radio frequency spectrum. It describes when unwanted energy from other devices or sources disrupts the intended radio signals, which can affect control or video links in drone operations. This makes it the precise way to name interference in RF environments. Antenna gain refers to how an antenna concentrates energy in a direction, not to interference itself. Wave propagation covers how radio waves travel and behave through space, including reflections and diffraction, rather than the disturbances that degrade a signal. A transceiver is the device that both transmits and receives signals, not the concept of interference. In practical terms, RF interference might come from nearby electronics, other wireless devices, or even atmospheric sources, and it’s what you’re trying to identify and mitigate when you hear terms like “RFI” in drone communications.
