Global telecommunication refers to the world wide communication through cable, telegraph, internet, telephone, or broadcasting. It facilitates the transfer of various data. facts, figures and information from one region to any other region of the globe. In broad sense, it refers to a wide variety of electrical and electronic communication systems used throughout the world. Modern telecommunication enables us to send and receive sound, videos, printed materials, and visual images in a fraction of a second.
Late 1960s saw the emergence of internet as an impotent instrument of global telecommunication. Internet is a enormous network of computers that connects many of the world's businesses, governments, institutions, and individuals. The Internet, which means interconnected network of networks, links millions and billions of smaller computer networks. It enables computer users throughout the world to send and receive messages, share information in a variety of forms. Compuers of all sorts, whether it is of an individual i.e. a personal computer or super computers and servers of various institutional bodies and government can be connected to the internet.
Telephone is a device for transmitting sound to a distance by cable or radio by altering acoustic vibrations to electrical signals. It is one of our most valuable means of global communication. In just a few seconds, one can telephone a person in any part of the world. In its most indispensable form, a telephone enables people to talk with one another at distances beyond the range of the human voice. Modern telephones are also capable of transmitting text messages, graphics and videos apart from traditional voice messages.
Radio is one of our most important means of global communication. It enables people to send words, music, codes, and other signals to any part of the world. Persons in aircraft and on ships can keep in contact with persons on land by using radio. People also use radio to communicate far into space.
These satellites are now an essential part of worldwide communications. A communication satellite is capable of transmitting a large number of phone calls or streaming videos in very little time. It is also essential for satellite telephony system. A ground station has a large dish aerial for transmitting and receiving radio signals.
The Global Telecommunications System (GTS) is a global grid for the transference of meteorological data from weather terminals, satellites and numerical weather forecasting centers.
The Global Telecommunication System (GTS) consists of an incorporated set of connections of meteorological telecommunication centres. The circuits of the GTS are framed with a amalgamation of terrestrial and satellite telecommunication associates. The GTS is well thought-out on a three stage basis, namely:
The Main Telecommunication Network is the hub network of the GTS. It connects jointly three World Meteorological Centres and 15 Regional Telecommunication Hubs. These are:
The Main Telecommunication Network (MTN) has the purpose of providing an regimented and dependable communication facility between its centres, with the intention of making sure the speedy and consistent global and interregional transfer of observational facts and figures, processed information and other data essential for Members.
The Regional Meteorological Telecommunication Networks consist of an integrated network of circuits interconnecting meteorological centres, which are assisted by radio broadcasts where essential. The Regional Meteorological Telecommunication Networks are to make certain the gathering of observational statistics and the local careful circulation of meteorological and other correlated information to Members. The RTHs on the MTN carry out a crossing point purpose between the Regional Meteorological Telecommunication Networks and the MTN.
The National Meteorological Telecommunication Networks facilitate the National Meteorological Centres to accumulate observational data and to accept and dispense meteorological information on a national stage.
Fibre optic cables are indispensable part of global telecommunication network as a channel for high speed data transfer across the globe. The largest fibre-optic cables can carry hundreds of thousands of telephone conversations or hundreds of television channels across the globe. Satellites and microwaves are also employed in global telecommunication.
Companies like AT&T, Microsoft, Vodafone, Orange, T-Mobile, Aces, and Singular Wireless are some the major players which operate in global telecommunication industry and provide the facility of global communication.
