Planning Permission
Planning permission or building permit refers to the approval needed for construction or expansion (including significant renovation), and sometimes for demolition, in some jurisdictions. House building permits, for example, are subject to building codes. There is also a "plan check" (PLCK) to check compliance with plans for the area, if any. For example, one cannot obtain permission to build a nightclub in an area where it is inappropriate such as a high-density suburb. The criteria for planning permission are a part of urban planning and construction law, and are usually managed by town planners employed by local governments. Failure to obtain a permit can result in fines, penalties, and demolition of unauthorized construction if it cannot be made to meet code. Generally, the new construction must be inspected during construction and after completion to ensure compliance with national, regional, and local building codes. Since building permits usually precede outlays for ...

Radio Antenna
In radio-frequency engineering, an antenna (American English) or aerial (British English) is an electronic device that converts an alternating electric current into radio waves (transmitting), or radio waves into an electric current (receiving). It is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductor segments ( elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive ...

Radio Waves
Radio waves (formerly called Hertzian waves) are a type of electromagnetic radiation with the lowest frequencies and the longest wavelengths in the electromagnetic spectrum, typically with frequencies below 300 gigahertz (GHz) and wavelengths greater than , about the diameter of a grain of rice. Radio waves with frequencies above about 1 GHz and wavelengths shorter than 30 centimeters are called microwaves. Like all electromagnetic waves, radio waves in vacuum travel at the speed of light, and in the Earth's atmosphere at a slightly lower speed. Radio waves are generated by charged particles undergoing acceleration, such as time-varying electric currents. Naturally occurring radio waves are emitted by lightning and astronomical objects, and are part of the blackbody radiation emitted by all warm objects. Radio waves are generated artificially by an electronic device called a transmitter, which is connected to an antenna, which radiates the waves. They are receiv ...

Free Speech
Freedom of speech is a principle that supports the freedom of an individual or a community to articulate their opinions and ideas without fear of retaliation, censorship, or legal sanction. The right to freedom of expression has been recognised as a human right in the Universal Declaration of Human Rights and international human rights law. Many countries have constitutional law that protects free speech. Terms like ''free speech'', ''freedom of speech,'' and ''freedom of expression'' are used interchangeably in political discourse. However, in a legal sense, the freedom of expression includes any activity of seeking, receiving, and imparting information or ideas, regardless of the medium used. Article 19 of the UDHR states that "everyone shall have the right to hold opinions without interference" and "everyone shall have the right to freedom of expression; this right shall include freedom to seek, receive, and impart information and ideas of all kinds, regardless of frontiers ...

Canadian Radio-television And Telecommunications Commission
The Canadian Radio-television and Telecommunications Commission (CRTC; ) is a public organization in Canada tasked with the mandate as a regulatory agency tribunal for various electronic communications, covering broadcasting and telecommunications. It was created in 1976 when it took over responsibility for regulating telecommunication carriers. Prior to 1976, it was known as the Canadian Radio and Television Commission, which was established in 1968 by the Parliament of Canada to replace the Board of Broadcast Governors. Its headquarters is located in the Central Building (Édifice central) of Les Terrasses de la Chaudière in Gatineau, Quebec. History The CRTC was originally known as the Canadian Radio-Television Commission. In 1976, jurisdiction over telecommunications services, most of which were then delivered by monopoly common carriers (for example, telephone companies), was transferred to it from the Canadian Transport Commission although the abbreviation CRTC re ...

Radio Format
A radio format or programming format (not to be confused with broadcast programming) describes the overall content broadcast on a radio station. The radio format emerged mainly in the United States in the 1950s, at a time when Radio broadcasting, radio was compelled to develop new and exclusive ways to programming by competition with Television broadcasting, television. The formula has since spread as a reference for commercial radio programming worldwide. A radio format aims to reach a more or less specific audience according to a certain type of programming, which can be thematic or general, more informative or more musical, among other possibilities. Radio formats are often used as a marketing tool and are subject to frequent changes, including temporary changes called "Stunting (broadcasting), stunting." Except for talk radio or sports radio formats, most programming formats are based on commercial music. However the term also includes the news, bulletins, DJ talk, jingles, c ...

FM Broadcasting
FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to transmit high fidelity, high-fidelity sound over broadcast radio. FM broadcasting offers higher fidelity—more accurate reproduction of the original program sound—than other broadcasting techniques, such as AM broadcasting. It is also less susceptible to Electromagnetic interference, common forms of interference, having less static and popping sounds than are often heard on AM. Therefore, FM is used for most broadcasts of music and general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequency, radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion of it, with few exceptions: * In the Commo ...

Non-commercial Educational
A non-commercial educational station (NCE station) is a radio station or television station that does not accept on-air advertisements (television advertisement, TV ads or radio advertisement, radio ads), as defined in the United States by the Federal Communications Commission (FCC) and was originally intended to offer educational programming as part, or whole, of its programming. NCE stations do not pay broadcast license fees for their non-profit organization, non-profit uses of the radio spectrum. Stations which are almost always operated as NCE include public broadcasting, community radio, and college radio, as well as many religious broadcasting stations. Nearly all non-commercial radio stations derive their support from listener support, grants and endowments, such as the Corporation for Public Broadcasting (CPB) that distributes supporting funds provided by Congress to support public radio. Reserved channels On the FM broadcast band, the Federal Communications Commission (FCC ...

Frequency Allocation
Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation of RF bands and their standardization. ITU definition The International Telecommunication Union defines frequency allocation as being of "a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions".ITU Radio Regulations, Section IV. Radio Stations and Systems – Article 1.16, definition: allocation (of a frequency band). ''Frequency allocation'' is also a special term, used in national frequency administration. Other terms are: Bodies Several bodies set standards for frequency allocation, including: * International Telecomm ...

Community Of License
In U.S., Canadian, and Mexican broadcasting, a city of license or community of license is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator. In North American broadcast law, the concept of ''community of license'' dates to the early days of AM radio broadcasting. The requirement that a broadcasting station operate a ''main studio'' within a prescribed distance of the community which the station is licensed to serve appears in U.S. law as early as 1939. Various specific obligations have been applied to broadcasters by governments to fulfill public policy objectives of broadcast localism, both in radio and later also in television, based on the legislative presumption that a broadcaster fills a similar role to that held by community newspaper publishers. United States In the United States, the Communications Act of 1934 requires that "the Commission shall make such distribution of licenses, frequenci ...

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the '' Wright Flyer'', the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet engine which enabl ...

Tower
A tower is a tall Nonbuilding structure, structure, taller than it is wide, often by a significant factor. Towers are distinguished from guyed mast, masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation tower, observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek language, Greek τύ ...
