Spectrum allocation

Definition

Spectrum allocation refers to the process of assigning specific frequency bands of the electromagnetic spectrum for various uses, ensuring efficient and interference-free communication. In the context of satellite communication for IoT, spectrum allocation plays a crucial role in enabling devices to communicate effectively over long distances and through various atmospheric conditions, as satellites rely on allocated frequency bands to transmit data to and from Earth.
