1. Electromagnetic spectrum

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 10 25 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus.

2. Frequency allocation

Frequency allocation (or spectrum allocation or spectrum management) is the allocation and regulation of the electromagnetic spectrum into radio frequency bands, normally done by governments in most countries. [1]

The radio spectrum is the radio frequency (RF) portion of the electromagnetic spectrum. In the United States, regulatory responsibility for the radio spectrum is divided between the Federal Communications Commission ( FCC) and the National Telecommunications and Information Administration ( NTIA ).

4. Electromagnetic spectrum

electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. Although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies.

5. United States Spectrum Allocation Chart

This chart portrays the frequency allocations in the electromagnetic spectrum for different purposes as specified by United States government. The Radio Frequency Spectrum Allocation Chart is the first and broadest level technical document to consult when planning uses for spectrum allocations in that nation's borders.

6. Table of Frequency Allocations Chart

The FCC's Table of Frequency Allocations consists of the International Table of Frequency Allocations ("International Table") and the United States Table of Frequency Allocations ("United States Table"). The FCC's Table of Frequency Allocations is codified at Section 2.106 of the Commission's Rules.

10. Spectrum Sharing

Spectrum sharing is a way to optimize the use of the airwaves, or wireless communications channels, by enabling multiple categories of users to safely share the same frequency bands. Spectrum sharing is necessary because growing demand is crowding the airwaves. Smartphones, the Internet of Things, military and public safety radios, wearable ...

11. Electromagnetic Spectrum Regulation

Spectrum allocation is a distribution of frequencies to radio services. An allocation designates the use of a given frequency band for use by one or more radio communication services. National and international tables of frequency allocations contain lists of these frequency band designations.
