Radio Frequencies (RF) are defined within what range?

Radio frequencies (RF) are categorized within the electromagnetic spectrum, particularly in the range of 3 kHz to 300 GHz. This range encompasses various sub-bands used for different communication technologies, including AM and FM radio, TV broadcasts, mobile phones, and Wi-Fi.

The lower bound of 3 kHz is significant because it begins at frequencies where radio waves can effectively propagate and be utilized for communication purposes. The upper bound of 300 GHz marks the transition into higher frequencies typically used in microwave and millimeter-wave technology. Frequencies above this limit enter into the range of infrared radiation, which is not classified as radio frequency.

Understanding this range is crucial for drone operations and any other radio-based communication systems, as it indicates where devices can effectively transmit and receive signals without interference from other types of electromagnetic waves.
