Study Notes
What is Telecommunication?
- Telecommunication is the transmission and reception of information over long distances through various electronic means such as telephone, radio, and internet.
Origin of Telecommunication
- The origin of telecommunication dates back to ancient times when humans used smoke signals, drumbeats, and homing pigeons to convey messages over long distances.
- The first modern telecommunication system was the electrical telegraph, invented by Samuel Morse in the 1830s.
Evolution of Transmission Media
- The transmission media in telecommunication have evolved significantly over the years:
- Initial transmission media: Electrical wires (telegraph) and radio waves (radio)
- 1920s: Coaxial cables were introduced for telephone networks
- 1960s: Satellite communication emerged, enabling global telecommunication
- 1980s: Fiber optic cables were introduced, increasing transmission speed and capacity
- 1990s: Wireless communication technologies like cellular networks and Wi-Fi emerged
Communication Channels
- Communication channels in telecommunication refer to the mediums through which information is transmitted:
- Wired channels: Coaxial cables, fiber optic cables, and twisted pair cables
- Wireless channels: Radio waves, microwaves, and infrared waves
Pre-Modern Long-Distance Communication
- Examples of pre-modern long-distance communication include:
- Smoke signals used by ancient civilizations like the Greeks and Romans
- Drumbeats used by African tribes to convey messages
- Homing pigeons used to carry messages during times of war and peace
