Radio Frequency (RF) [RF]
Radiofrequência ou RF refers to the oscillatory change in a circuit, waveguide, or transmission line in the range from around 20,000 times per second (20 kHz) to around 300 billion times per second (300 GHz), roughly between the upper limit of audio and the lower limit of infrared light. Under certain conditions, RF becomes radio waves of electromagnetic radiation. These waves can propagate at the speed of light, over large distances, and through various materials, air, and even the vacuum of space.

Radio frequency also refers to the commonly used communications bands that a UAS uses to communicate between the GCS and the UAV.
