What is The Meaning Of Telecommunication System:

 

Telecommunication System” means any electrical Electromagnetic Electronics, Optical or Optoelectronics. system for the Emission,Conveyance, Switching or Reception of any Intelligence whether or not that subjected to Rearrangement, Computation or any other Process in the Course of Operation of the system and includes Cable Television Transmission System and Terminal Equipment. Hey there! Did you know that humans have been sending messages over long distances using sound and visual signals since prehistoric times?
It’s true! In ancient Greece, a man named Phidippides even ran over 240 kilometers in just two days to ask for Sparta’s help against the Persians before the battle of Marathon. And even later on, mail was delivered across the United States using a relay of men on horseback.
It’s amazing what people can accomplish, isn’t it?

 

  • In Indian Seraye’s’ Telecommunication Fundamentals

 

In India Seraye’s were built Pre-Mughal Muslim period. These served as staging posts for the horse-riding messengers. The remains of the earliest communication system related to the Mughal period can be seen by the roadside between “Agra” & “Srinagar”.These are Seraye’s of masonry heaps or half-columns at suitable distances, for accommodation, drummers used to send advance messages of Mughal King Jahangir’s procession.

 

CHANGHEZ KHAN ORGANIZED. Telecommunication Fundamentals

 

Changhez khan for carrying but organized a pigeon relay service across Asia and Europe. Lighting of fire on hill tops, release of smoke was an early form of visual signaling.
At sea the traditional method of communication was to hoist flags at different part of ships to communicate depicting messages. Later on this method of flag signaling was adopted on land. Semaphore, a code for signaling alphabet with the help of 2 flags continued to be used for long time.

 

  • Definition of Telecommunication Telecommunication Fundamentals

 

Telecommunication  defined any transmission, emission or reception of signs, signals, writing, images, sounds or intelligence of any nature by radio optical, or another electromagnetic system.
  • The Discovery Of Static Electricity
The discovery of static electricity and invention of Layden jar in 1746 for its strange paved the way for further experiments, which led Benjamin Franklin to identify Conductors and Insulators.
  • Telegraphy
 Telegraphy over electrical conductors was described since 1753.Telecommunication Fundamentals
 
On these finding Georges Lesage built a communication link in 1774 with separate wires for different alphabets. This was improved upon by Sir Francis Ronald’s using single wire.
  • First Telegraph link

 

The first telegraph link constructed in 1786 between Madrid and Aranjuez over a distance of 42 Km. With the invention of electric cell by Volta a source of continuous electric currant become available and the demonstration of magnetic effect of electric currant by Oersted in 1820 facilitated electrical communication.
 Telegraph A system that made possible the transmission of messages by sending electrical signals through wires. The first telegraph lines were laid in the early 19th century. It was used to convey messages quickly over long distances. The telegraph line was laid by Samuel Morris from Washington, DC to Baltimore, Maryland in 1844. The invention of the telegraph revolutionized communication and laid the foundation for the telephone and the Internet.

  • Origin of the Telegraph

The first experiments with the telegraph carried out in the late 18th and early 19th centuries. Claude Chope in France invented the visual telegraph system in the 1790s, which used signaling devices mounted on towers.
  • Telecommunication System Telecommunication Fundamentals
Telecommunication system can establish with a minimum of two users. With the increases in the number of users the utility of the network is improved. Telecommunication system may be private, corporate, public or government.
 
The basic components of a telecommunication system

  • Transmitter

This device that generates information or signals and enables them to sent.

  • Receiver

This device receives the received signals and converts them into information. Transmission Medium: It is the path or medium through which signals sent. This medium can be wireless (radio waves) or wired (fiber optic cable, telephone line).
