What is WLAN and how does it relate to Wi-Fi?
WLAN stands for Wireless Local Area Network. It is a technology that enables devices to connect and communicate wirelessly within a limited area, typically within a range of a few hundred feet. WLAN is essential for creating networks in homes, offices, and public spaces, allowing for the mobility of devices without the need for wired connections.
Wi-Fi, on the other hand, is a specific type of WLAN technology that uses radio waves to transmit data. The term “Wi-Fi” is often used interchangeably with WLAN, but Wi-Fi is actually a brand name that refers to the wireless networking standards outlined by the Institute of Electrical and Electronics Engineers (IEEE). In essence, all Wi-Fi networks are WLANs, but not all WLANs necessarily use the Wi-Fi standard.
What are the main advantages of using WLAN technology?
One of the primary advantages of WLAN technology is mobility. Users can move freely within the range of the network without being tethered by cables, enabling greater flexibility and convenience, especially in dynamic environments like offices and homes. This mobility allows multiple devices to connect to the same network simultaneously, supporting a wide array of applications, from casual browsing to streaming and gaming.
Another significant advantage is ease of installation and maintenance. Setting up a WLAN typically requires less physical infrastructure than a wired network, which means lower installation costs and fewer disruptions to the environment. Additionally, troubleshooting and expanding a WLAN is generally more straightforward, as new devices can be added easily without the need for extensive rewiring or network design.
How is WLAN set up in a typical home or office environment?
Setting up a WLAN usually begins with selecting a wireless router that incorporates the appropriate Wi-Fi standards. This router serves as the central point of communication for all connected devices. Once the router is configured by connecting it to the internet service provider’s modem and configuring the network settings, users can establish a secure network by enabling Wi-Fi encryption methods such as WPA3.
After the router is set up, devices can be connected to the WLAN by selecting the network from the available Wi-Fi options and entering the designated password. It’s essential to regularly monitor and maintain the network settings to ensure optimal performance and security. Additionally, user devices can be connected or disconnected easily, making it adaptable to changes and new requirements in the home or office setup.
What are some common security risks associated with WLAN?
WLAN networks are susceptible to several security risks, one of the most significant being unauthorized access.
