Frequency Management and Spectrum
The electromagnetic spectrum is a finite natural resource that must be carefully managed to enable the countless wireless services modern society depends upon. From mobile communications and broadcasting to radar systems and satellite links, every radio-based technology requires access to specific portions of the spectrum. Effective frequency management ensures that these diverse services can coexist without harmful interference while maximizing the economic and social value derived from spectrum use.
Frequency management encompasses a broad range of technical, regulatory, and operational activities. It includes the allocation and assignment of frequencies to specific services and users, the development of technical standards that enable coexistence, the monitoring of actual spectrum usage to detect violations and interference, and the resolution of interference problems when they occur. As wireless technologies continue to proliferate and the demand for spectrum grows, sophisticated management techniques become increasingly essential.
