Important Telecommunication Full Forms, Acronyms & Abbreviations

A transmitter and a receiver are required for communication. To put it another way, telecommunication is a technology that allows us to send and receive data over a great distance.

Now, as an example, let’s try to comprehend this. This article is also being read via telecoms. You must be connected to the Internet if you are reading this article on your phone or computer.

In short, Telecommunication is the transfer of data by cable, radio, optical, or other electromagnetic networks using a variety of methods. Let’s read some important “Telecommunication Full Forms, Acronyms & Abbreviations
