WLAN

A Wireless Local Area Network (WLAN) is a type of local area network that uses wireless communication to connect devices, such as computers and smartphones, within a specific area. Unlike a wired network, which requires physical cables to establish connections, WLANs facilitate connections through radio frequency (RF) signals, providing a more flexible networking option.

Key Components of WLAN

There are two main components in a WLAN:

Key WLAN Standards

There are several WLAN standards, defined by the Institute of Electrical and Electronics Engineers (IEEE) 802.11 series. Some of the most common standards include:

WLAN Security

As WLANs use wireless signals to transmit data, they can be susceptible to various security threats. Some essential security measures include:

To maintain a secure WLAN, it’s essential to use the appropriate security standard, change default settings, and regularly update firmware to address any security vulnerabilities.
