Wireless Communication: Definition & Different Types

Here you will get knowledge about “Wireless Communication, its Definition & Different Types”. We have described all types of Wireless Communication in detail here. You will get complete knowledge about Wireless Communication here. Keep Visiting – Vlcinfo.

Definition of Wireless Communication

• It is a transfer of data without using physical connections (wires or cables).
• It uses radio frequency waves for transmission of data.
• Examples:
  • Phones
  • Tablets
  • Laptops
  • Routers
  • IoT devices
• These devices use wireless technology for each other communication.

Different Types of Wireless Communication

Here we have listed different types of wireless communication below,

1. Wi-Fi

• Full Form: Wireless Fidelity
• It uses IEEE 802.11 standards.
• It is used in limited area (home, office, campus or public hotspot).
• Works in 2.4 GHz to 5 GHz frequency bands.

2. Bluetooth

• Used for short-range communication
• Used within range of 10 meters.
• Works in 2.4 GHz frequency band.

3. Satellite Communication

• It uses satellites to provide signals over long distances.
• It provides transfer of voice, data and multimedia services globlly.
• It is used in satellite phones, satellite television, GPS and remote sensing.
• It is used for marine and aviation communication, disaster response and military communication.

4. Infrared Communication

• It uses infrared light waves to transfer data.
• It is used over short distances.
• It needs direct line of sight between the transmitter and a receiver

5. Cellular Communication

• It uses cell tower network to transfer data.
• It is used over large geographic areas.
• Uses :
  • To make voice calls
  • Send text messages and
  • Access the internet on mobile devices.

6. NFC (Near Field Communication)

• It is used for very close-range communication
• Used within a few centimeters.
• Works in 13.56 MHz frequency band.
• Uses :
  • Contactless payments
  • Ticketing
  • Access control
  • Data exchange
  • Smart cards
  • NFC tags and
  • NFC-enabled devices.

7. RFID (Radio Frequency Identification)

• It uses radio waves. For identification and tracking of objects.
• It consists :
  • (1) RFID tags (transponders) attached to objects
  • (2) RFID readers (interrogators).
• Uses :
  • Inventory management
  • Ticketing
  • Access control
  • Contactless payment
  • Supply chain management
