Wireless LANs
Wireless Local Area Networks (WLANs) are computer networks that use high frequency radio waves instead of cables to connect devices. WLANs are commonly used in homes, businesses, schools, and public places, allowing users to connect to the network without the need for physical cables.
WLANs use the IEEE 802.11 standards to provide wireless connectivity. These standards define the physical and data link layers of the network protocol stack, and are commonly known as Wi-Fi. The most widely used standards are:
802.11a: Uses the 5 GHz frequency band and provides data rates up to 54 Mbps.
802.11b: Uses the 2.4 GHz frequency band and provides data rates up to 11 Mbps.
802.11g: Uses the 2.4 GHz frequency band and provides data rates up to 54 Mbps.
802.11n: Uses both the 2.4 GHz and 5 GHz frequency bands and provides data rates up to 600 Mbps.
802.11ac: Uses the 5 GHz frequency band and provides data rates up to 6.9 Gbps.
WLANs use access points (APs) to provide wireless coverage to devices within their range. The AP acts as a bridge between wireless devices and a wired network, such as the Internet or an intranet. WLANs may also use wireless controllers to manage multiple APs and provide centralized management and security.
WLANs face a number of security challenges, such as unauthorized access, eavesdropping, and interference. To address these challenges, WLANs use security measures such as encryption, authentication, and access control. Common WLAN security protocols include WEP, WPA, and WPA2.
