3.1. Communications-Electronics. The specialized field concerned with the use of electronic devices and systems for the acquisition or acceptance, processing, storage, display, analysis, protection, disposition, and transfer of information.
3.2. Radio Frequency Spectrum. The frequencies (or wavelengths)
associated with radio wave propagation (3 kilohertz (3 X 103 hertz) to 3,000 gigahertz (3 X 1012
hertz) or a wavelength of 100 kilometers to 0.1 millimeter,
respectively).
3.3. Spectrum Management. The function where use of the radio
frequency spectrum is controlled to ensure the electromagnetic compatibility
of communications-electronics systems. Requirements for use of the radio
frequency spectrum are presented, reviewed, and, to the degree possible,
satisfied for communications-electronics systems being acquired or brought
into use.
