FM Extended Band In Brazil
In Brazil, the FM extended band ( pt, faixa estendida), abbreviated eFM, refers to the extension of the FM broadcast band between 76.1 and 87.3 MHz, beyond the conventional band of 87.5 to 108 MHz that was previously used. The reclaimed spectrum was previously used to broadcast television channels 5 and 6 before the country's digital television transition. The first eFM stations began broadcasting on May 7, 2021, and the spectrum is being used as part of a plan to migrate AM stations to the FM band. History The idea of converting the former channels 5 and 6 for sound broadcasting use had been first floated in Brazil in 2013, as a method to support AM stations by migrating them to FM; that year, President Dilma Rousseff signed a law that started the AM–FM migration process in Brazil. Since then, 1,720 of the country's 1,781 AM outlets have requested migration, including in areas where no further FM stations could be added. Jovem Pan News in São Paulo was allowed by the Minist ...

FM Broadcast Band
The FM broadcast band is a range of radio frequencies used for FM broadcasting by radio stations. The range of frequencies used differs between different parts of the world. In Europe and Africa (defined as International Telecommunication Union (ITU) region 1) and in Australia and New Zealand, it spans from 87.5 to 108 megahertz (MHz) - also known as VHF Band II - while in the Americas (ITU region 2) it ranges from 88 to 108 MHz. The FM broadcast band in Japan uses 76 to 95 MHz, and in Brazil, 76 to 108 MHz. The International Radio and Television Organisation (OIRT) band in Eastern Europe is from 65.9 to 74.0 MHz, although these countries now primarily use the 87.5 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 87.5 to 108 MHz band. Frequency modulation radio originated in the United States during the 1930s; the system was developed by the American electrical engineer ...

Public Broadcaster
Public broadcasting involves radio, television and other electronic media outlets whose primary mission is public service. Public broadcasters receive funding from diverse sources including license fees, individual contributions, public financing and commercial financing. Public broadcasting may be nationally or locally operated, depending on the country and the station. In some countries a single organization runs public broadcasting. Other countries have multiple public-broadcasting organizations operating regionally or in different languages. Historically, public broadcasting was once the dominant or only form of broadcasting in many countries (with the notable exceptions of the United States, Mexico and Brazil). Commercial broadcasting now also exists in most of these countries; the number of countries with only public broadcasting declined substantially during the latter part of the 20th century. Definition The primary mission of public broadcasting is that of public servic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Broadcast Engineering
Broadcast engineering is the field of electrical engineering, and now to some extent computer engineering and information technology, which deals with radio and television broadcasting. Audio engineering and RF engineering are also essential parts of broadcast engineering, being their own subsets of electrical engineering. Broadcast engineering involves both the studio and transmitter aspects (the entire airchain), as well as remote broadcasts. Every station has a broadcast engineer, though one may now serve an entire station group in a city. In small media markets the engineer may work on a contract basis for one or more stations as needed. Duties Modern duties of a broadcast engineer include maintaining broadcast automation systems for the studio and automatic transmission systems for the transmitter plant. There are also important duties regarding radio towers, which must be maintained with proper lighting and painting. Occasionally a station's engineer must deal with c ...

Radio In Brazil
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, 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 modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highway Advisory Radio
A travelers' information station (TIS), also called highway advisory radio (HAR) by the United States Department of Transportation, is a licensed low-powered non-commercial radio station, used to broadcast information to the general public, including for motorists regarding travel, destinations of interest, and situations of imminent danger and emergencies. They are commonly operated by transportation departments, national and local parks departments and historic sites, airport authorities, local governments, federal agencies, colleges and universities, hospitals and health agencies, and for special events and destinations. United States Current regulations and applications In the United States, most Travelers Information Stations (TIS) are licensed by the Federal Communications Commission (FCC), although stations operated by U.S. national parks and others under U.S. federal government jurisdiction are licensed by the National Telecommunications and Information Administration ...

Rádio Nacional
Rádio Nacional (''National Radio'') is a Brazilian radio network belonging to the government-owned corporation EBC (''Empresa Brasil de Comunicação'', Brazil Communication Company), formerly known as ''Radiobrás''. History The Brazilian system of public radio began to be assembled from the nationalization of the ''Rádio Nacional'', a Rio de Janeiro-based station in 1936, by President Getúlio Vargas. In 1958, two years before the inauguration of new capital Brasília, ''Rádio Nacional Brasília'' was founded, and in 1976 the FM version, ''Nacional FM'' was assembled in the same city. In 1977, the shortwave service ''Rádio Nacional da Amazônia'' was created, covering much of Brazil with the aim of showing the Amazon culture to the rest of the country. In 2006, ''Nacional'' launched the ''Radio Nacional do Alto Solimões'', covering municipalities of the Alto Solimões region of Amazonas state. On May 7, 2021, five EBC transmitters on 87.1 FM—four of them for Rádi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Telecommunications Agency (Brazil)
The National Telecommunications Agency ( pt, Agência Nacional de Telecomunicações) or Anatel is a special agency in Brazil created by the general telecommunications act (Law 9472, 16/07/1997) in 1997 and governed by Decree 2338 of 07/10/1997.

Megahertz
The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s−1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz). Some of the unit's most common uses are in the description of periodic waveforms and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the clock speeds at which computers and other electronics are driven. The units are sometimes also used as a representation of the energy of a photon, via the Planck relation ''E'' = ''hν'', where ''E'' is the photon's energy, ''ν'' is its frequency, ...
