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 intelligence is 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’
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.
Changhez khan for carrying but changhez 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 is 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.
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.
- The first telegraph line
Samuel Morris’s first telegraph line was laid from Washington DC to Baltimore in 1844. The first message sent on this line was “What hath God wrought,” a quote from the Bible.
- Electric Telegraph
It development of the electric telegraph began in the 1830s. In Britain, William Cook and Charles Wheatstone patented the electric telegraph in 1837. Then in 1844, Samuel Morris and Alfred Weil in America built a telegraph system to send messages using Morse code.
- The Decline of the Telegraph
After the invention of the telephone in the early 20th century, the development of radio and the Internet reduced the use of the telegraph. But due to its invention, the foundation of modern communication system has been laid. Its effects are felt even today.
Telegraph has ushered in a new era in human history. Where the immediate transmission of information became possible and thanks to this the world has become closer to each other.
- Origin of the Telegraph
The first experiments with the telegraph were 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 system can be established 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 is the A device that generates information or signals and enables them to be sent.
- Receiver
This device receives the received signals and converts them into information. Transmission Medium: It is the is the path or medium through which signals are sent. This medium can be wireless (radio waves) or wired (fiber optic cable, telephone line).
Types of telecommunication systems
Telephone systems
These are used for voice communication and include landline and mobile phone systems.
- Radio and TV broadcast systems
These systems are used to convey information to a large number of people.
- Satellite communication
It enables global communication using satellites.
- Internet
It is a global network that connects different networks and exchanges different types of information through it.
- Wireless communication
These systems enable communication through radio waves, microwaves or infrared, such as Wi-Fi, Bluetooth, etc.
Advantages of Telecommunication System
- Instant Information Exchange
Facilitation of sending and receiving information instantly to remote locations.
- Global Connectivity
Ability to connect people around the world. and facilitate the exchange of data. Assistance in emergency situations
Provision of immediate information in emergency situations and support for rescue operations. Telecommunication systems have turned the world into a global village.

- Government Sector
Defense and Police telecommunication are examples of government sector.
- Public Or Global Telecommunication System
Public telecommunication service is not restricted to the national boundaries.
National public telecommunication networks are part of Global system. In fact the global telecommunication system is the World’s largest network. A telecommunication system has to be built according to standards and operated according to regulations established by the national authorities or the concerned international organizations.
Advantages of Public Telecommunication System
- Easy and quick contact
Through this service, people are provided with the facility to connect with each other instantly. People can communicate anytime and anywhere through mobile phones, landlines, and the Internet.
- Emergency Services
Enables immediate assistance and access to services in emergency situations, such as police, ambulance, and firefighting. It also plays a very important role in services.
- Social Connectivity
Provides people with the facility to stay in constant touch with their friends and family. People stay connected with each other with the help of social media platforms, messaging, apps, and voice calls, video calls.
- Economic Benefits
Promotes business and trade. Companies can establish effective communication with their customers and partners, thereby increasing their business.
- Educational Opportunities
Facilitates access to educational content through online education and e-learning platforms. Facilitates remote learning and teaching to students and teachers.
