What is Radio Spectrum?
Radio spectrum is the part of the electromagnetic spectrum ranging from 1 Hz to 3000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, have become widely used in modern technology, particularly in telecommunication.
The spectrum is divided into different frequency bands, and each band has been allocated for a specific application ranging from aeronautical and maritime communication to AM and FM radio stations.
Demand for wireless broadband has soared due to technological innovation, such as 3G and 4G mobile services, and the rapid growth of wireless internet services. With the explosion of technologies requiring the use of the radio spectrum, spectrum managers are looking for ways to increase spectrum availability for broadband and maintain critical services.
