WLAN (Wireless Local Area Network) & use of WLAN

WLAN stands for Wireless Local Area Network. It is a type of wireless network that allows devices to connect and communicate with each other without the use of physical cables. A WLAN typically consists of a wireless access point (AP), which connects the wireless devices to the wired network, and one or more wireless clients, such as laptops, smartphones, and tablets, that connect to the AP. The AP acts as a bridge between the wired network and the wireless clients. WLANs use radio waves to transmit data between devices and typically operate in the 2.4GHz or 5GHz frequency bands. They use a variety of wireless networking protocols, such as Wi-Fi, to ensure secure and reliable communication between devices. WLANs are commonly used in homes, small businesses, and public spaces such as cafes and airports, but are also used in enterprise settings to provide wireless connectivity for employees. WLAN (Wireless Local Area Network) is useful for several reasons: Mobility: WLAN allows users to ...

WiFi technology : Wireless communication between Device and Internet

Wi-Fi technology is a wireless networking standard that allows devices to connect to the internet and communicate with each other without the use of physical cables. It is based on the IEEE 802.11 standard and uses radio waves to transmit data. Wi-Fi networks use access points (APs) to connect wireless devices to the internet and to other devices on the network. When a device wants to connect to a Wi-Fi network, it will first broadcast a request to discover available networks in the area. Once the device finds the desired network, it will request to connect by sending a message to the AP, which includes a unique identifier called a Media Access Control (MAC) address. The AP will then check its list of authorized devices and if the requesting device's MAC address is on the list, it will grant access to the network. Once access is granted, the device will be assigned an IP address and the AP will establish a secure connection, using protocols like WPA2 or WPA3. Wi-Fi technology uses ...
