Examples include telephone networks, cable television or internet access, and fiber-optic communication. Anything and everything you see around yourself having wires and uses electricity to operate belongs to wired technology
  4. 4. Wireless Technology The term wireless refers to the communication of information over a distance, without requiring wires, cables or electrical conductors. Information is transmitted through air , without requiring any cables by using electro magnetic waves like radio frequencies, infrared, satellite etc.
  5. 5. Types of Wireless Communication The different types of wireless communication mainly include, IR wireless communication, satellite communication, broadcast radio, Microwave radio, Bluetooth, etc. 1. Satellite Communication 2. Infrared Communication 3. Broadcast Radio 4. Microwave Communication 5. Wi-Fi 6. Mobile Communication Systems 7. Medical 8. Wireless Power Transfer
  6. 6. 1. Satellite Communication A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver(s) at different locations on Earth.
  7. 7. Uses Of Satellites Television : Network TV : Live news broadcasting Telephones : in-flight phone communications on airplanes : After Disaster Navigation : GPS : IRNSS : Google Maps : Offline Maps Weather : Forecasting : Hurricanes : EL Nino Climate and Environmental Monitoring : Polar melting : Ocean temperature : Forest fires : Emission of greenhouse gases Safety : Airborne pollution : Search & rescue missions : Black box : Development : Access to education in rural areas : Developing nations Space Science : Satellite telescopes : Observing space : Monitoring threats on earth Land Stewardship : Under ground water : Mineral resources : Measure land Military : Early warning ICBM : Satellite weapons : Military communication : Spy satellites : Missile defense systems ( PAD, Brahmos,) : Drones
