What are Telecommunications?
Telecommunications is the transmission of distance information data through electronic means and technology. Information data transport to telecommunications circuits by electrical signals.
What we use in our day-to-day activities, such as television, computers, and our mobile devices, are some of the most shared examples used as headsets of information in telecommunications.
So to answer what telecommunications are, we must know that it is about the interaction of information between distances, and they denote all types of voice, data or video transmission.
The concept of telecommunications includes a series of transmission technologies such as those mentioned above, although many others such as satellites, fibre optics, etc. Throughout this post, we will investigate what telecommunications are, among other issues among others.
How do Telecommunications Work?
Telecommunications, in terms of the transmission of info utilizing electromagnetic waves, work with frequencies emitted by a powerful electromagnetic emitter. It makes waves of the same nature with different frequencies, depending on the function that leads to the cape.
It can be high-frequency, ultra- frequency, low-frequency, microwave, etc. The study and claim of the technique that designs systems allow long-distance communication through the transmission and greeting of signals.
History of Telecommunications
The invention of the telegraph started telecommunications and gave way to the telephone. The man tried has overcome detachments to send and receive signals from very early times. For this, he used fume signals, instrumental sounds, human messengers or chains of fire signals.
However, only with the appearance of the postal mail in its different versions, some older than others, did a true remote communication system appear. It generally aims at communicating with the king or the grand metropolis with its distant subjects or colonial territories.
For its part, the first systems of rapid remote communication were created in the Modern Age. Thanks to the dominance of electricity, using it to transmit simple messages, generally limited to one word, emerged.
This invention was consolidated in the following years as the great modern means of communication, especially in the United States, thanks to the expansion of the railways. It served as the basis for future inventions, such as the “talking telegraph” (the telephone) or “wireless telegraphy” (radiocommunication).
Finally, after the creation of computers and their incorporation into material exchange networks, new technologies add modems, sonar, microwaves, telecommunications satellites, cellular telephony, WiFi, and other modern modes of transmission of information. Information digitized by electromagnetic waves.
Types of Telecommunications
There are many habits to classify telecommunications according to different elements. For example, we can differentiate between unidirectional communications, those in which the dispatcher is always the sender, and the bidirectional ones. The receivers finally also occupy the role of the sender. That is, there is feedback.
On the other hand, captivating into account the nature of its specific technology, we can differentiate between:
1. Radio Communications
It refers not only to the broadcast of radio waves in AM and FM from commercial stations, whose programming must retrieve by the public on their radio devices and short-wave radio devices, such as those used for triangulation and radio stations. Military communications.
2. Telephony
The old Graham Bell wireline telephony replace throughout the 20th century by a whole contemporary telephone industry, which usages satellites and broadcast towers to send and receive electromagnetic signals of specific incidence. The device then changes into sound waves, recovering the speaker’s voice with minimal distortion and delay.
3. TV
The great invention that transformed the mass media in the 20th century survive by adapting to the times, through cable broadcasts or streaming through the Internet, to bring both audio and images to the getting devices in each home, either live and direct delayed.
4. Internet
Today practically everything connects to the Internet, the great network of computer networks, which allows the reciprocal sending of information over enormous distances. It is an intricate network of mutually interconnected computers that share an immense volume of data of any nature through fibreglass cables, coaxial cables, or radio waves (WiFi). The Internet allows various services such as the World Wide Web, email, streaming service, etc.
5. Fax
A technology now extinct, but that serves as an example, and that contained using telephone lines to send the imitation of an image taken from a text, that is, something similar to a photocopier, whose originals were yet far away. Since the influx of the Internet, it has been considered obsolete and abandoned throughout the world.
What does a Telecommunications Engineer Do?
As you well know, telecommunications engineering is a speciality responsible for solving various problems concerning the transmission and welcome of signals and the interconnection of networks. We must tolerate in mind that today the basis of information systems is electronics, so it needs to be processed and transmitted.
Although it is true that to work as a telecommunications engineer, it is necessary to complete a university degree such as the following: degree in electronic telecommunications engineering, the degree in engineering in telecommunication systems and the degree in engineering in telecommunication knowledge.
However, at Euroinnova, we propose a series of online training related to telecommunications in which it is not essential to have a university degree. Through our online training, you can learn all about the technologies and telecommunications services that provide you with knowledge. to create tracking systems for a product or a service and implement the development of communications systems.
Functions of Telecommunications
Although there are many functions, the above opinions are the most common apart from teaching or processing images. Although it can also carry out the following tasks, among many others:
- Analyze and assess new technological trends in the field of telecommunications.
Performs tasks installation, operation and upkeep of telecommunications equipment. - Participates in the efficient administration of the different phases of telecommunications projects, taking into account the market’s needs.
- In short, in a summary of telecommunications, the profession is about a profession with a future trajectory since it can work in any market sector.
- A free professional expert with the option of choosing from a multitude of professional opportunities can dedicate to the field of banking, logistics and transport, images. And even defence, among other sectors that you can develop professionally.
What are the Main Objectives of Telecommunications?
Carry out the policy of the arena of action of telecommunications, focused on satisfying the entire society’s needs. Develop the programs in performance with the Telecommunications Regulation and Control Agency and with the public.
Ensure the massification of Information and Communication Skills in the populace of Ecuador, upsurge the Telecommunications Infrastructure.
Advise and facilitate the management of the Telecommunications Regulation and Control Agency to ensure that all the criteria of the National Development Plan meeting.
To function as a connecting link between the administration of the sector and bureaucratic decisions.
Design and execute agendas. And short and medium-term schemes that respond to the development regulations of the subdivision.
Guide the procedures of design, creation, establishment, development and updating of a Telecommunications Information System.
Carry out practical research, reports and specific studies in telecommunications. The socio-economic conditions determine its growth. It authorizes the design, formulation, implementation and evaluation of sector policies and institutional development.
Regularize and achieve cooperation capitals, both nationally and internationally, ordering with the telecommunications development policies. Bring the monitoring, switch and evaluation to the policies, programs and projects of the telecommunications sector.
Conclusion
When we speak of telecommunications, we refer to science. And practice of transmitting information through electromagnetic means finished using a set of specialized techniques and materials. Such info may consist of data textual, audio, video or a combination of the three.
