Telecom Synonym

Telecommunications is that the broadcast of symbols, signs, communications, texts, footage and noises or intellect of any flora by wire, radio, optical or different magnetism systems. Telecommunication happens once the exchange of knowledge between communication participants includes the employment of technology. It’s transmitted either electrically over physical media, like cables, or via radiation. Such transmission ways area unit usually divided into communication channels that afford the benefits of multiplexing. The term is usually employed in its plural, telecommunications; as a result of it involves many alternative technologies.
Early suggests that of the act over a distance enclosed graphical indications, like inspirations, smolder gestures, semaphore telegraphs, signal flags, and optical heliographs. Different samples of pre-modern long-distance communication enclosed audio messages like coded drumbeats, lung-blown horns, and loud whistles. twentieth and twenty-first-century technologies for long-distance communication typically involve electrical and magnetism technologies, like the telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, and communications satellites.
Now, we need to the actual concept about telecom synonyms and acronym or abbreviation in this latest technology of the global world. I would like to arrange some importance word wishes are used in the telecom field during installing and commissioning the equipment.
What is the meaning of 2G, 3G……5G or 6G?
Easily we all are expressing our feelings with loudly – First Generation, Third Generation……..Fifth Generation or Sixth Generation accordingly.
