2. In computing terminology, the term "wired" is
used to differentiate between wireless
connections and those that involve cables.
While wireless devices communicate over the
air, a wired setup uses physical cables to
transfer data between different devices and
computer systems.

3. Wired Technology
Wired technology is more associated with wired communication
Wired communication refers to the transmission of data over a wire-
based communication technology.
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. 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. 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. 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. 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

8. 2. Infrared Communication
Communication with the help of infrared rays
1. Security lights : Sensing
2. Burglar alarms: Sensing
3. Remote controls
4. Data links over short distances between computers or mobile phones

9. 3. Broadcast Radio
Broadcast Radio is the distribution of audio content to a dispersed
audience via any electronic mass communications medium, but typically
one using the electromagnetic spectrum (radio waves), in a one-to-many model.
1. AM
2. FM
3. Pirate Radio
4. Sports , Police

10. Microwave transmission is the transmission of information or
energy by electromagnetic waves whose wavelengths are
measured in small numbers of centimeter; these are
called microwaves. ( low frequency ).
1. Used in small frequency radios.
2. Microwave oven
4. Microwave Communication

11. Wi-Fi
Wi-Fi is a low power wireless communication , that is used by various electronic
devices like smart phones, laptops, etc. In this setup, a router works as a
communication hub wirelessly.
Wi-Fi - Wireless Fidelity : Full form
Uses Of WI-FI
1. Share your internet
2. Share resources between PCs
3. Print & scan
4. Remote control of your entertainment system
5. Listen to music

12. 6. Stream video
7. Play online games
8. Turn Your Smartphone into a Remote Control
9. Tether Your Smartphone to Your Computer for Internet Anywhere :
Hotspot

13. The advancement of mobile networks is enumerated by generations.
Many users communicate across a single frequency band through mobile phones.
Cellular and cordless phones are two examples of devices which make use of
wireless signals.
Telephony was introduced in India in 1882.
The total number of telephones in the country stands at 1002.05 million
1. 2G
2. 3G
3. 4G
4. 6G : Japan
Bluetooth
NFC
Mobile Communication Systems

14. Wireless Technology In Medical Field
1) Patient Health Monitoring
2) Tele-surgery
3) Mobile wireless biosensor systems
4) Wireless tracking of patients

15. Wireless power transfer (WPT) or wireless energy
transmission is the transmission of electrical power from
a power source to a consuming device without using
discrete manmade conductors.
1. Wireless Charging
2. Long Range Conduction
