It is a broad term that includes a wide range of information transmission technologies.

Such as telephones (wired and wireless), microwave radio-link communications, fiber optics, satellites, radio and television transmissions, the Internet, and telegraphs.


From the etymological point of view conferring to the online etymological dictionary, telecommunications comes from the Greek prefix “tele.”

Stages of a Telecommunication System

A single complete telecommunication circuit consists of two stations, each equipped with a transmitter and a receiver. The transmitter and receiver at any station can be combine into a single device a transceiver.

And also, The signal transmission medium can be through an electrical cable or wire (also known as “copper”), fiber optics, electromagnetic fields, or light.

However, The transmission of free space and the reception of data using electromagnetic fields is wireless communications.

Types of Telecommunications Networks

Moreover, The modest form of telecommunications occurs between two stations, but it is typical for multiple transmitting and receiving stations to exchange data.

However, The Internet is the most significant example of a telecommunications network.

On a smaller scale, examples include:
