Radio Broadcasting
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale). Television broadcasting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Top-level Domain
A top-level domain (TLD) is one of the domains at the highest level in the hierarchical Domain Name System of the Internet after the root domain. The top-level domain names are installed in the root zone of the name space. For all domains in lower levels, it is the last part of the domain name, that is, the last non empty label of a fully qualified domain name. For example, in the domain name www.example.com, the top-level domain is .com. Responsibility for management of most top-level domains is delegated to specific organizations by the ICANN, an Internet multi-stakeholder community, which operates the Internet Assigned Numbers Authority (IANA), and is in charge of maintaining the DNS root zone. History Originally, the top-level domain space was organized into three main groups: ''Countries'', ''Categories'', and ''Multiorganizations''. An additional ''temporary'' group consisted of only the initial DNS domain, arpa, and was intended for transitional purposes toward the ...

Intelsat
Intelsat S.A. (formerly INTEL-SAT, INTELSAT, Intelsat) is a multinational satellite services provider with corporate headquarters in Luxembourg and administrative headquarters in Tysons Corner, Virginia, United States. Originally formed as International Telecommunications Satellite Organization (''ITSO'', or INTELSAT), from 1964 to 2001, it was an intergovernmental consortium owning and managing a constellation of communications satellites providing international telecommunications and broadcast services. As of June 2022, Intelsat operated a fleet of 52 communications satellites which was then one of the world's largest fleets. In 2020, the company announced plans to procure, build and launch seven C-band satellites over the next several years. These C-band satellites will contribute to the acceleration of America's 5G buildout. In early 2022, the company announced contracts for four GEO software defined satellites (SDS), two in partnership with Airbus and two in partnership ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

TEAMS (cable System)
TEAMS (The East African Marine System) is an initiative spearheaded by the government of Kenya to link the country to the rest of the world through a submarine fibre optic cable. It was first proposed as an alternative to EASSy, the East African Submarine Cable System. The Kenyan government had grown frustrated with the ownership model favoured by South Africa, the time it was taking and what it perceived as an attempt by South Africa to control the cable. As a result, in November 2006, the Kenyan government decided to partner with the Emirates Telecommunication Establishment (Etisalat) to build its own fibre optic cable. Although the Kenyan government has decided to pursue their own fibre optic cable, they are still committed to EASSy. History Five companies — Alcatel-Lucent, Tyco Telecommunication, Fujitsu Corporation, NEC Corporation and Huawei Technologies — had placed their bids for the building of the TEAMs undersea cable. On October 11, 2007, Alcatel-Lucent were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EASSy (cable System)
The Eastern Africa Submarine Cable System (EASSy) is an undersea fibre optic cable system connecting countries in Eastern Africa to the rest of the world. EASSy runs from Mtunzini in South Africa to Port Sudan in Sudan, with landing points in nine countries and is connected to at least ten landlocked countries — which will no longer have to rely on satellite Internet access to carry voice and data services. EASSy was the highest capacity system serving sub-Saharan Africa until the commissioning of WACS. It has a 2 fibre-pair configuration with a design capacity of more than 10 terabit per second (Tbit/s). It is the first to deliver direct connectivity between east Africa and Europe / North America. It is the only system with built-in resilience end-to-end. EASSy interconnects with multiple international submarine cable networks for onward connectivity to Europe, the Americas, the Middle East and Asia. The project, partially funded by the World Bank, was initiated in Jan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Very Small Aperture Terminal
A very-small-aperture terminal (VSAT) is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s up to 16 Mbit/s. VSATs access satellites in geosynchronous orbit or geostationary orbit to relay data from small remote Earth stations (terminals) to other terminals (in mesh topology) or master Earth station "hubs" (in star topology). VSATs are used to transmit narrowband data (e.g., point-of-sale transactions using credit cards, polling or RFID data, or SCADA), or broadband data (for the provision of satellite Internet access to remote locations, VoIP or video). VSATs are also used for transportable, on-the-move (utilising phased array antennas) or mobile maritime communications. History The concept of the geostationary orbit was originated by Russian theorist Konstantin Tsiolkovsky, who wrote articles on space travel around the beginning of t ...

Microwave Radio Relay
Microwave transmission is the transmission of information by electromagnetic waves with wavelengths in the microwave frequency range of 300MHz to 300GHz(1 m - 1 mm wavelength) of the electromagnetic spectrum. Microwave signals are normally limited to the line of sight, so long-distance transmission using these signals requires a series of repeaters forming a microwave relay network. It is possible to use microwave signals in over-the-horizon communications using tropospheric scatter, but such systems are expensive and generally used only in specialist roles. Although an experimental microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. During the war, the British Army introduced the Wireless Set No. 10, which used microwave relays to multiplex eight telephone channels over long distances. A link across the English Channel allow ...
