Meaning of Telecommunication Engineering

A communications network is a group of transmitters, receiver. The telecommunication is a way of transmission of information, over significantly long distances so the people are able to communicate. In ancient times of human era, telecommunications widely use the visual signals, such as optical heliographs, beacons, semaphore telegraphs,  smoke signals, signal flags, and audio messages. But in the modern age the age of electricity and electronics, telecommunications is also now widely using of electrical devices such as teletypes, telephones, and telegraphs and fiber optics and its associated electronics.

Networks which are used in Telecommunication

The network which is used telecommunications network to transmit the signals is a collection of the terminals, the links and nodes. These all are connect with each other to enable telecommunication between users of thenetworks. Telecommunication networks are use circuit switchingand message switching techniques for communication. The terminals which are used in the network have a unique address so that the messages and connections can be transmitted to the recipients. The group of these addresses in the network is address space of the network. The links are normally used to connect the nodes so that they themselves built a transmissionnetwork which used for transmission of the message across the link.

 These are few examples of telecommunications networks:

  • The networks through computers
  •  Internet which is the fastest network
  •  Phone networks
  •  Telex
  •  ACARS network used in aeronautics


Components of The Telecommunication Networks

The telecommunication networks are generally have five basic components. These are present in each network which is of any type and for any use. The network include terminals, processors of telecommunications, channels, telecommunications control software, and computers.

Network structure of Telecommunication Network

In any telecommunications network there are three parts or we can say planes:

  • The control plane is used to carry control information called as signaling.
  • The data plane also known as user plane  helps to carry the network traffic.
  • The telecommunication network management plane use to carry the operations and administration traffic required for network management.



The data networks are used widely throughout the world. Because these are used to connect individuals and organizations widely. Data networks is used to connect the users together to allow to access resources that are hosted outside of the particular provider. The Internet is used to connect many data networks of different organizations and all those are operating under a single address. For example: WAN, MAN, LAN, CAN and VPN

There are some basic features of telecommunication networks:

  1. The area of the network size is between 5 and 50 km in diameter.
  2. These generally do not belongs to a single organization.
  3. The equipment that interconnects these network, are provided by an association that provide the service to others also.
  4. The telecommunication networks share resources at high speeds in the network.
