  1. TeleCommunication Media Devices Ms. K. Scruggs

  2. Objective • Given instructions, the learner will discuss different components of telecommunications with 85% accuracy.

  3. Telecommunication • Telecommunication is the transmission of information over significant distances, for the purpose of communication.

  4. Earlier Telecommunication Devices • Early communication involved the use of visual signals and audio messages such as: • Beacons • Smoke • Semaphore telegraphs • Signal Flags • Optical heliographs • Drumbeats • Lung-blown horns • Loud whistles

  5. Modern Age Telecommunication Devices • Modern Age devices used electricity and electronics such as: • Telegraph • Telephones • Teletypes • Radio • Microwave communication • Fiber Optics • Orbiting Satellites and Internet

  6. Wireless Media

  7. Media Transmission • A sending device is a generally computer. • A communication device, such as a modem, that converts the computer signal into signals supported by the communication channel. • A Communications Channel or path, such as telephone lines, cable, or a wireless transmission link, over which the signal are sent. • A receiving device that accepts the incoming signal, which is a general computer. • Communication software

  8. Radio Signals • Radio signals travel in a straight line from one source to the other.

  9. Microwave • A microwave signal is sent through space in the form of electromagnetic waves. The signal is also sent is a straight line. Doppler Radar Microwave Station Microwave Station

  10. Satellite Transmissions • Communication satellites are placed in orbit 22,300 ft above the surface of the Earth. • http://www.bing.com/maps/default.aspx?v=2&cp=44.023938~-99.71&style=h&lvl=4&tilt=-89.875918865193&dir=0&alt=7689462.6842358

  11. Post Q’s? • What is the transmission of information over significant distances, for the purpose of communication? • Telecommunication • Name several earlier form of telecommunication devices. • Beacons, Smoke, Semaphore telegraphs, Signal Flags, Optical heliographs, Drumbeats, Lung-blown horns, and Loud whistles • Name several modern forms of telecommunication devices. • Telegraph, Telephones, Teletypes, Radio, Microwave communication, Fiber Optics , and Orbiting Satellites and Internet • What travels in a straight line form one source to the other? • Radio Signal • ________ is sent through space in the form of electromagnetic waves. • Microwave signal
