WIRELESS COMMUNICATION-Wireless Communication refers to the transmission of information from one point to another

Wireless Communication refers to the transmission of information from one point to another without the use of physical wires or cables, relying instead of electromagnetic waves. This technology allows for transfer of data, voice, and video across various distances, including short-range connections like Bluetooth and longer- range systems like cellular networks.

Types of Wireless Communication: In Network type

1.       Wireless Personal Area Network (WPANs): Short- range networks for connecting devices in a small area (ex: Bluetooth, Sigsbee).

2.       Wireless Local Area Networks (WLANs): Connect devices within a limited area, like a home or office (ex: Wi-Fi).

3.       Wireless Metropolitan Area Network (WMANs): Cover a large area then WLANs, such as a city.

4.       Wireless Wide Area Networks (WWANs): Cover large geographical areas, often using cellular technologies (ex: LTE 5G).

5.       Satellite Networks: Provide Communication across the global using Satellite.

Based on Communication: 

·         Simplex: one way communication (ex: Radio Broadcasting).

·         Half-Duplex: Two- way communication, but only device can transmit at a time (ex: walkie-talkies).

·         Full-Duplex: Two-way communication where both devices and can transmit and receive simultaneously (ex: mobile phones).

Ø  The world of wireless communication is constantly evolving, with new technologies, and applications emerging all the time.

Ø  These diverse methods play a crucial role in our daily lives, connecting people, devices, and information across the globe.

Applications of Wireless Communication:

§  Mobile Communications: Mobile phones, cordless phones, and remote controls all utilize wireless communication for voice and data transmission, enabling quick communication and access information.

§  Internet of Things (IOTs): Wireless communication is a crucial for connecting various devices, enabling them to exchange data and automate tasks without physical wires.

§  Wireless Sensor Networks: These networks enable the monitoring of various parameters in diverse environments, including environmental monitoring, traffic management, and surveillance.

§  Satellite Communication: Wireless communication via satellites used for broadcasting television signals, weather forecasting, and global positing system (GPS).

§  Micro wave Communication: Used for long- distance communication and satellite communication.

§  Wireless LANs (Wi-Fi): Provides wireless internet access in public hotspots, homes and offices.
