What is a Wireless Network? - (BCA / B.Tech)

Wireless Network & Protocol in Multimedia in Hindi | Wireless Network and Protocol in Hindi:

Wireless networks and protocols have made communication and connectivity easy in the modern era.
This technology is useful in every field, whether it is education, medicine, or business.
However, continuous improvement and research is needed to solve the challenges related to security and reliability.
The future of wireless networks is bright, and its use will become even more widespread with new technologies like 5G, IoT, and smart devices.
A wireless network is a type of computer network in which data and information are exchanged without wires.
It uses radio waves, infrared signals, and other wireless technologies.
Today, wireless networks are being used in every field, such as homes, offices, schools, hospitals, and public places.

Types of Wireless Network in Hindi | Types of Wireless Networks:

Wireless Local Area Network (WLAN): This is used in a small area (like a home or office). Wi-Fi is a popular example of this.

Wireless Metropolitan Area Network (WMAN): This covers a city or a large area. Example: WiMAX.

Wireless Personal Area Network (WPAN): This is used to connect small personal devices. Example: Bluetooth, Infrared.

Wireless Wide Area Network (WWAN): This is used in large areas such as a country or at a global level. Example: Mobile network (3G, 4G, 5G).

Advantages of Wireless Network in Hindi | Advantages of Wireless Networks:

Flexibility: Users can connect to the network from any location.
Cost Saving: There is no need for wires, which reduces the installation cost.
Portability: The device can be taken anywhere and connected.
Easy Installation: Installation is easy and fast due to the absence of the need for cables and wires.

Protocol of Wireless Network in Hindi | Protocols of Wireless Networks:

A protocol is a set of rules and standards that are used for the exchange of data in a network. Some important protocols for wireless networks are as follows:

Wi-Fi:

This is the most common wireless protocol.
It is used for internet connection and networking.
Follows the IEEE 802.11 standard.

Bluetooth:

This is part of WPAN.
It is used to connect small devices such as mobiles, laptops, and speakers.

ZigBee:

This is used for low power and low data rate devices.
Its use is increasing in smart homes and IoT.

LTE and 5G:

These are used for mobile networks.
They provide high speed and low latency.

NFC:

This is used for data transfer over short distances.
It is popular in mobile payment systems.
Challenges of wireless networks

Security:

Data can be accessed without permission, so security is a big challenge.
Signal Interference: There can be interference from radio signals from other devices.
Speed and Coverage: Speed and coverage can be less compared to a wired network.
Power Consumption: Wireless devices use more battery.
