Definition of "Radio Spectrum" |
A band of frequencies used for radio communication. / Radio spectrum refers to the part of the electromagnetic spectrum corresponding to radio frequencies – that is, frequencies lower than around 300 GHz or, equivalently, wavelengths longer than about 1 mm. Electromagnetic waves in this frequency range, called radio waves, are used for radio communication and various other applications, such as heating. The generation of radio waves is strictly regulated by the government in most countries, coordinated by an international standards body called the International telecommunication Union. / The Land mobile service, or Land mobile radio service, is regulated in the United States by the Federal Communication Commission in CFR 47 Part 90 for non-federal government wireless use between land-based mobile and fixed stations. |
