From television, radio channels, telephone and fax services and even the Internet have been the best exponents of these technologies, so you should know more about them. types of telecommunications that changed the world.

What are Telecommunications?
Telecommunications is the infrastructure that uses electromagnetic waves to send, receive and exchange information using multiple forms of projection, such as sounds, texts, images and even videos.
On the other hand, telecommunications require a series of special technologies and devices to decipher and decode the signals, so that they can be read all the information as it was transmitted.
The 6 types of telecommunications existing in the market
The best way to determine the types of telecommunications existing today is through the technology used. Since its creation until today, up to 6 alternatives have emerged that are still used.
1. Radio communications
It is perhaps the first form of telecommunications that man discovered and used for his contact with other individuals. With the research of the radio frequency waves, devices were created that were capable of receiving and sending them in a coded manner.
Because these waves are not visible and are all over nature, they can be used to upload information and transport it in an encrypted manner throughout the entire system. radio spectrum.
One of the radio communications The best known is precisely the radio, which emerged with an amplitude modulation (AM) system, but later reached frequency modulation with many more benefits.
We can also classify in this type of telegraphic communications to military devices and inventions, which are frequently used for contact between the missions of armies around the world.
2. Telephony
Shortly after the emergence of radio, the telephony made its first advances and is currently one of the most widely used telecommunications structures worldwide, and not only for transmitting audio.
This technology also uses electromagnetism for the Sending messages using antennas, satellites and a complex system of infrastructure specially designed for use in this field.
Receiving devices (cell phones and telephones) They are those that capture said information and decode it, transforming it into audio with excellent quality these days, and with very minimal loss or distortion.
Equally Two channels are used to transport data and audio separately, the first used for the Internet, while the second is suitable for calls that are completely live.
3. Television
Maybe the TV is surfing the imminent disappearance of this type of telecommunication, because with the arrival of the Internet and the services of streaming, people are watching less and less content through the television.
Once again, the radio spectrum is being used to take a frequency, which is decoded to tune in to all the content loaded there. Since TV is an audiovisual medium, the transmitted information shares sound and video at the same time.
Complex infrastructures are required, such as traditional receiving antennas and satellites, the latter emerging with the arrival of the cable TV which partially replaced the electromagnetic system.
However, we can now enjoy the original concept of television through the Internet (without actually being a form of telecommunication because the web is now used to load content).
4. Fax (discontinued)
El fax It is no longer usable today because the Internet made its technology completely obsolete. For this purpose, the telephone infrastructures to send messages and texts through a series of codes.
In that sense, the fax required a special device to copy the document and transmit it over the local telephone line. This could take some time to complete, but not too long.
On the other hand, for a long time it was considered a business environment where executives communicated with their partners remotely and shared important documents, practically in real time.
5. Internet
Today, the best type of telecommunications used on a large scale and globally is the Internet. This works through a system of interconnected networks through computers, servers and all kinds of equipment that constantly exchange information.
In turn, it is connected to what is known as World Wide Web, a vast universe of networks and servers that can be accessed using search engines and typing in their web addresses.
The internet takes advantage all means of telecommunications known to date, including radio frequency wireless networks, satellite systems, coaxial, electrical, fiber optic, copper cabling and even telephone networks.
6. Electronic mail (E-mail)
There is a debate on whether the email like any other type of telecommunications due to its individuality, since even though it must be connected to the Internet in order to function, it turns out to be practically independent.
Email arose from the original concept of postal mail, but because the traditional form required human resources and long time intervals to transport information, it became obsolete and the idea was taken up again with the arrival of the internet.
Anyone has an email with which they can subscribe to any of the services available on the network, although they primarily connect people instantly through encrypted messages and protected by complex protocols.
Conclusions
Communication has always been a human need. The simple fact of expressing our requirements and desires through codes (oral, body, written and now telecommunication language) has meant a important development for man.
All of these types of telecommunications are the ones we have had throughout history and up to the present day, several of which remain, even though they have practically fallen into disuse. The Internet has been the meeting point for everyone and has absorbed its main concepts.
