Wireless LAN Basics

Wireless Local Area Network (WLAN) is a type of computer network that uses high-frequency radio waves instead of wired connections for connecting devices within a limited area such as a home, office building, or campus. WLAN allows devices to communicate with each other and access the internet wirelessly using radio frequency (RF) signals.

WLANs are typically implemented using Access Points (APs) that act as wireless hubs or switches. An AP connects wireless devices to a wired network and manages the flow of traffic between the wireless and wired networks. WLAN devices communicate with each other using a wireless protocol such as Wi-Fi, Bluetooth, or ZigBee.

WLANs are popular because they provide flexibility and mobility, enabling users to connect to the network from any location within the coverage area without being tied down to a wired connection. WLANs also allow for easy network expansion and modification, as new devices can be added to the network without the need for additional wiring.

However, WLANs also present unique security challenges due to the nature of wireless communication. WLANs can be vulnerable to eavesdropping, interference, and unauthorized access if not properly secured. As a result, it is important to implement proper security measures such as encryption and access control to ensure the confidentiality and integrity of data transmitted over a WLAN.
