Wireless Local Area Network (WLAN) is a LAN that uses radio waves instead of cables, offering flexibility and ease of setup but with potential security vulnerabilities.

Benefits of Using WLAN

WLANs offer significant benefits, including ease of setup and cost-effectiveness. They eliminate the need for extensive cabling, making installation simpler and less expensive. This flexibility allows for quick deployment and adjustments as needed.

Additionally, WLANs enhance user mobility and device connectivity. Users can move freely within the network's coverage area without losing connection, making it ideal for dynamic work environments. The scalability of WLANs also allows for easy expansion by adding more access points or users.

Securing Your WLAN

Securing your WLAN is crucial to protect sensitive data and ensure network integrity.

• Encryption: Use WPA2 for robust security.

• Access Control: Implement MAC address filtering to block unauthorized devices.

• Regular Audits: Conduct frequent security assessments to identify vulnerabilities.

WLAN vs. Wired Networks

Choosing between WLAN and wired networks depends on various factors, including installation, scalability, and user experience.

• Installation: WLANs are easier and quicker to set up, requiring less physical infrastructure. Wired networks, on the other hand, need extensive cabling and hardware, making them more time-consuming and costly to install.

• Scalability: WLANs offer high scalability, allowing easy addition of users and access points. Wired networks require more physical cabling and hardware, making scalability more complex and expensive.

Essential Components of WLAN

Understanding the essential components of a WLAN is crucial for setting up a robust and efficient network. These components work together to provide seamless connectivity and ensure the network's functionality. The central device in this setup is the Access Point (AP), which connects all wireless devices to the network. Stations, which include devices such as computers and mobile phones, connect wirelessly to the network. The Basic Service Set (BSS) refers to a group of these stations connected to the network, forming the basic building block of a WLAN. The Distribution System connects multiple access points, either through wired or wireless means, to extend the network's reach, ensuring comprehensive coverage.
