“A good network engineer doesn't just solve problems; they anticipate and prevent them.”

Wireless Networking

The concept of "wireless networking" describes the process of connecting devices to a network using wireless technology so they may exchange data and interact without physical wires. Computers, cellphones, tablets, printers, and other gear connect with one another via radio waves, infrared signals, or other wireless communication methods in a wireless network.

Types of Wireless Networking

Different forms of wireless networking exist, depending on the technology, application, and coverage region. The primary categories are as follows:

  1. Wireless Local Area Network (WLAN)

    2. Description: WLAN is a wireless network that provides connectivity within a limited area, such as a home, office, or campus. The most common technology used in WLANs is Wi-Fi.

  2. Wireless Personal Area Network (WPAN)

    3. Description: WPANs are used for short-range communication between devices, typically within a few meters. Technologies like Bluetooth, Zigbee, and Infrared (IR) are commonly used in WPANs.

  3. Wireless Metropolitan Area Network (WMAN)

    4. Description: WMAN covers a larger area than WLAN, typically spanning a city or a large campus. WiMAX (Worldwide Interoperability for Microwave Access) is a technology used in WMANs.

  4. Wireless Wide Area Network (WWAN)

    5. Description: WWAN provides wireless connectivity over a large geographic area, often spanning multiple cities or even countries. This type of network uses technologies like cellular networks (3G, 4G, 5G) and satellite communications.

  5. Wireless Mesh Network

    6. Description: In a wireless mesh network, each node (device) acts as a relay point, forwarding data to other nodes. This type of network is decentralized and self-healing, meaning it can automatically reroute data if a node fails.

  6. Wireless Ad Hoc Network

    7. Description: This is a temporary network formed without a central infrastructure, where each device communicates directly with others in a peer-to-peer manner. It's often used in situations where a fixed network isn't available.

  7. Cellular Networks

    8. Description: These are large-scale networks used for mobile communication, divided into small geographic areas called cells. Each cell is served by a base station, and technologies like GSM, CDMA, LTE, and 5G are used.

  8. Satellite Networks

    9. Description: These networks use satellites to provide wireless connectivity across vast distances, including remote or rural areas where other forms of wireless networks are impractical.


Applications / Computer Network

A system of connected devices that can interact and share resources is called a computer network. Numerous applications in diverse sectors and businesses make use of these networks. Here are a few typical uses for computer networks:
