Telecommunication: Definition, Network, Elements and More


Telecommunication is a technique that consists of the transmission of a message from one point to another.

It covers all types of distant communication. The word includes the Greek prefix ‘Tele,’ which means “distance” or “far.”

Basically, Telecommunication is the transmission of distance information data electronically and technologically.

However, a primary telecommunication circuit comprises two stations, each equipped with a receiver and a transmitter, combined to create a transceiver.

Telephone, radio, television, and data transmission through computers are part of the telecommunications sector.

Let us add that, it is the Set of means of remote communication or transmission of words, sounds, images, or data in the form of impulses or electronic or electromagnetic signals.

What is the Network Telecommunication?

  • A telecommunications network consists of multiple interlinked transmitter and receiver stations that exchange information.
  • Moreover, the most extensive and well-known network is the Internet.
  • However, Other smaller networks are telephone networks and private radio broadcasts.
  • Example: Internet and Networks.

What are the Elements of Telecommunication?

  • The elements that make up a telecommunications system are the following:

1. The transmitter

  • It transforms or encodes the messages into the signal through a transmission medium or communication channel.
  • And also, its physical nature may modify the signal on its way from the transmitter to the receiver.
  • Therefore, the receiver must have a decoding mechanism capable of recovering the message within certain signal degradation limits.
  • However, there might be interference in the communication channel such as noise, message propagation time, lousy signal.

2. Receiver

  • He is the one who receives the message, and in some cases, it is the ear of the human eye, and the mind does the retrieval of the message.

What is the System of Telecommunication?

  • In a telecommunications system, cables, fiber optics, or electromagnetic fields transmit telecommunication signals.
  • Basically, the areas that are free of transmission and reception of data by electromagnetic fields are known as Wireless and Radio.

What are the Examples of Telecommunication?

1. Radio

  • The private radio stations in Cuba also provide for the decentralization of the country’s Radio Broadcasting communications.
  • It must pay various taxes that may increase to pay this license to the beneficiary, to continue its radio-electric exploitation.
  • There are currently seven private radio stations with state concessions for a maximum period of 10 years.
  • However, these are the stations that would be privatizing, which helps improve communications, independent of any political label

2. Telephone

  • The first telephone conversation in Spanish took place in Havana in October 1877, just seven months after Alexander Graham Bell told it.
  • And also, a patent on the phone was granted.
  • In 1888, the privileges of a telephone transmission were granted to Red Telefónica de la Habana, SA, that managed to install 1,500 telephones in a decade.
  • However, the modernization of the obsolete national transmission network began with the construction of the National Fiber Optic System.
  • Let us add that, it also started the process to achieve complete digitization of the telephone.

3. Television

  • In 1958 the country had 25 television transmitters with a power of 150.5 kW, installed in Havana, Matanzas, Santa Clara, Ciego de Ávila, Camagüey, Holguín and Santiago de Cuba.
  • Basically, three national channels with seven transmitters each organize the service.
  • These were CMQ Televisión, Unión Radio Televisión and Telemundo.

4. Internet

  • The first Internet connection in Cuba was made in September 1996 at 64 kbps.
  • The total bandwidth between Cuba and the rest of the planet is only 209 Mbit / s upstream and 379 Mbps downstream.
  • Satellite internet accesses to the network. In 2008, Cuba had 190,000 private Internet users.
  • Let us add that, in 2011, the submarine fiber optic cable between Venezuela and Cuba was completed and began operating in January 2013.

5. Mobile telephone

  • The Empresa de Telecomunicaciones de Cuba SA (ETECSA) operates the cellular telephone network in Cuba, available in 900 Mhz throughout the national territory in GSM.
  • Basically, to enjoy the 3G Network in Cuba, the client must be in an area under 3G coverage, and the terminal of his cell phone must be compatible with the WCDMA standard in the 900 MHz frequency.
  • At present, the coverage of this technology in our country allows us to appreciate a higher data transmission speed, multimedia capacity, and better quality in transmitting voice and video in real-time.
