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.

Wired Technology

Wired technology is more associated with wired communicationWired 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

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.

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 Communication2. Infrared Communication3. Broadcast Radio4. Microwave Communication5. Wi-Fi6. Mobile Communication Systems7. Medical8. Wireless Power Transfer

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.

Uses Of Satellites

Television : Network TV : Live news broadcastingTelephones : in-flight phone communications on airplanes : After Disaster

Navigation : GPS : IRNSS : Google Maps : Offline MapsWeather : 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 landMilitary : Early warning ICBM : Satellite weapons : Military communication :

Spy satellites : Missile defense systems ( PAD, Brahmos,) : Drones

2. Infrared Communication

Communication with the help of infrared rays

1. Security lights : Sensing2. Burglar alarms: Sensing3. Remote controls4. Data links over short distances between computers or mobile phones

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. AM2. FM3. Pirate Radio4. Sports , Police

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

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

6. Stream video7. Play online games8. Turn Your Smartphone into a Remote Control9. Tether Your Smartphone to Your Computer for Internet Anywhere : Hotspot

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

Mobile Communication Systems

Wireless Technology In Medical Field

1) Patient Health Monitoring

2) Tele-surgery

3) Mobile wireless biosensor systems

4) Wireless tracking of patients 

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.
