What is Electromagnetic Spectrum Management?

Electromagnetic Spectrum Management (ESM) is the process of managing the use of radio spectrum in order to minimize harmful interference while ensuring that the spectrum is used most efficiently and with the greatest benefit. The means by which spectrum management endeavors to implement its goals are: allocation of frequency bands to radio services; writing rules for the compatible use of allocated bands; and making interference-free frequency assignments to individual transmitters within the allocated frequency bands. Effective spectrum management is becoming increasingly important as the use of wireless communication explodes.
