World Radiocommunication Conference
The World Radiocommunication Conference (WRC) is a conference organized by the ITU to review and, as necessary, revise the Radio Regulations, the international treaty governing the use of the radio-frequency spectrum as well as geostationary and non-geostationary satellite orbits. It is held every three to four years. Prior to 1993, it was called the World Administrative Radio Conference (WARC); in 1992, at an ''Additional Plenipotentiary Conference'' in Geneva, the ITU was restructured, and later conferences became the WRC. At the 2015 conference (WRC-15), the ITU deferred their decision on whether to abolish the leap second to 2023. The most recent World Radio Communication Conference (WRC-23) took place from 20 November to 15 December 2023 in Dubai Dubai (Help:IPA/English, /duːˈbaɪ/ Help:Pronunciation respelling key, ''doo-BYE''; Modern Standard Arabic, Modern Standard Arabic: ; Emirati Arabic, Emirati Arabic: , Romanization of Arabic, romanized: Help:IPA/English, / ...

International Telecommunication Union
The International Telecommunication Union (ITU)In the other common languages of the ITU: * * is a list of specialized agencies of the United Nations, specialized agency of the United Nations responsible for many matters related to information and communications technology, information and communication technologies. It was established on 17 May 1865 as the International Telegraph Union, the first formal and permanent international organization. The organization significantly predates the UN, making it the oldest UN agency. Doreen Bogdan-Martin is the Secretary-General of ITU, the first woman to serve as its head. The ITU was initially aimed at helping connect Telegraphy, telegraphic networks between countries, with its mandate consistently broadening with the advent of new communications technologies; it adopted its current name in 1932 to reflect its expanded responsibilities over radio and the telephone. On 15 November 1947, the ITU entered into an agreement with the newly cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Regulations
Radio regulation refers to the regulation and licensing of radio in international law, by individual governments, and by municipalities. International regulation The International Telecommunication Union (ITU) is a specialized agency of the United Nations (UN) that is responsible for issues that concern information and communication technologies. ''ITU Radio Regulations'' are the set of ITU's regulations governing electromagnetic spectrum from 9 kHz to 275 GHz. The reasons are that the radio waves spectrum is on the one hand considered to be a limited natural resource, on the other side some radio waves are able to propagate on considerable distances and interfere with radio services abroad. Government regulation United States In the United States, radio is regulated by the Federal Communications Commission The Federal Communications Commission (FCC) is an independent agency of the United States government that regulates communications by radio, television, wir ...

World Administrative Radio Conference
The World Administrative Radio Conference (WARC) was a 1979 technical conference of the International Telecommunication Union (ITU) where delegates from member nations of the ITU met to revise or amend the entire international Radio Regulations, radio regulations pertaining to all telecommunication services throughout the world. The conference was held in Geneva, Switzerland, with preparatory conferences held in Panama City, Panama. One outcome of the 1979 meeting was the allocation of WARC bands, three new amateur radio bands. In 1992, at an ''Additional Plenipotentiary Conference'' in Geneva, the ITU was restructured and as a result from 1993 the conference became known as the World Radiocommunication Conference or WRC.

Leap Second
A leap second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC), to accommodate the difference between precise time (International Atomic Time (TAI), as measured by atomic clocks) and imprecise solar time#Mean solar time, observed solar time (UT1), which varies due to Earth rotation#Changes, irregularities and long-term ΔT (timekeeping), slowdown in the Earth's rotation. The UTC time standard, widely used for international timekeeping and as the reference for civil time in most countries, uses TAI and consequently would run ahead of observed solar time unless it is reset to UT1 as needed. The leap second facility exists to provide this adjustment. The leap second was introduced in 1972. Since then, 27 leap seconds have been added to UTC, with the most recent occurring on December 31, 2016. All have so far been positive leap seconds, adding a second to a UTC day; while it is possible for a negative leap second to be needed, this has not ha ...

Telecommunication Conferences
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics. Other early pioneers in electrical and electronic tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Organizations
Radio is the technology of telecommunication, communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna (radio), antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, radio control, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by Modulation, modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the tran ...
