International Telecommunication Union
(ITU Constitution and Convention). In line to the ITU Constitution and Convention and the ITU International Telecommunication Regulations (ITR), this ITU Radio Regulations belong to the basic documents of the International Telecommunication Union

Radio Regulation In The United States
Regulation of the radio airwaves in the United States was enforced to eliminate different stations from broadcasting on each other's airwaves. Regulated by the Federal Communications Commission, standardization was encouraged by the chronological and economic advances experienced by the United States of America. Commenced in 1910, before the Communications Act of 1934
Communications Act of 1934
was passed, the Federal Radio Commission was the first organization established to control the functioning of radio as a whole through the Commerce Clause. Airwaves run across interstate and international waters, leading to some form of regulation

Treaty
A treaty is an agreement under international law entered into by actors in international law, namely sovereign states and international organizations. A treaty may also be known as an (international) agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms

International Law
International law
International law
is the set of rules generally regarded and accepted as binding in relations between states and between nations.[1][2] It serves as a framework for the practice of stable and organized international relations.[3] International law
International law
differs from state-based legal systems in that it is primarily applicable to countries rather than to private citizens. National law may become international law when treaties delegate national jurisdiction to supranational tribunals such as the European Court of Human Rights
European Court of Human Rights
or the International Criminal Court. Treaties

Abbreviation
An abbreviation (from Latin
Latin
brevis, meaning short [1]) is a shortened form of a word or phrase. It consists of a group of letters taken from the word or phrase. For example, the word abbreviation can itself be represented by the abbreviation abbr., abbrv., or abbrev. In strict analysis, abbreviations should not be confused with contractions, crasis, acronyms, or initialisms, with which they share some semantic and phonetic functions, though all four are connected by the term "abbreviation" in loose parlance.[2]:p167An abbreviation is a shortening by any method; a contraction is a reduction of size by the drawing together of the parts. A contraction of a word is made by omitting certain letters or syllables and bringing together the first and last letters or elements; an abbreviation may be made by omitting certain portions from the interior or by cutting off a part. A contraction is an abbreviation, but an abbreviation is not necessarily a contraction

Electromagnetic Spectrum
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies. The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications

Radio Frequency Spectrum
Radio
Radio
frequency (RF) is any of the electromagnetic wave frequencies that lie in the range extending from around 7004200000000000000♠20 kHz to 7011300000000000000♠300 GHz, roughly the frequencies used in radio communication.[1] The term does not have an official definition, and different sources specify slightly different upper and lower bounds for the frequency range. RF usually refers to electrical rather than mechanical oscillations. However, mechanical RF systems do exist (see mechanical filter and RF MEMS). Although radio frequency is a rate of oscillation, the term "radio frequency" or its abbreviation "RF" are used as a synonym for radio – i.e., to describe the use of wireless communication, as opposed to communication via electric wires

Radiocommunication Service
Radiocommunication
Radiocommunication
service is according to Article 1.19 of the International Telecommunication
Telecommunication
Union´s (ITU)RR,[1] defined as “a service…involving the transmission, emission and/or reception of radio waves for specific telecommunication purposes”. Radiocommunication
Radiocommunication
is sub-divided into space and terrestrial radiocommunication. Space radiocommunication is defined in RR Article 1 as “any radiocommunication involving the use of one or more space stations or the use of one or more reflecting satellites or other objects in space”. Terrestrial radiocommunication is defined as “any radiocommunication other than space radiocommunication or radio astronomy”.

Radio Station
A radio station is a set of equipment necessary to carry on communication via radio waves. Generally, it is a receiver or transmitter, an antenna, and some smaller additional equipment necessary to operate them. Radio stations
Radio stations
play a vital role in communication technology as they are heavily relied on to transfer data and information across the world.[1] More broadly, the definition of a radio station includes the aforementioned equipment and a building in which it is installed. Such a station may include several "radio stations" defined above (i.e. several sets of receivers or transmitters installed in one building but functioning independently, and several antennas installed on a field next to the building). This definition of a radio station is more often referred to as a transmitter site, transmitter station, transmission facility or transmitting station
