LAN in Wi-Fi refers to a Local Area Network that utilizes Wi-Fi technology for wireless communication between devices within a limited area, such as a home, office, or public hotspot. In this context, LAN refers to the network of devices connected wirelessly via Wi-Fi access points.
The use of LAN in Wi-Fi enables devices like smartphones, laptops, tablets, and smart devices to connect to each other and to the internet wirelessly within a specific area. It provides flexibility and mobility for users to access resources and services without being tethered to a wired connection.
Wi-Fi itself is a technology that allows devices to wirelessly connect to a LAN. When you use Wi-Fi to connect your devices at home or in an office, you are essentially connecting them to a LAN over a wireless medium. Therefore, your Wi-Fi network functions as a LAN for devices within its coverage area.
To connect to a LAN Wi-Fi, you typically need to connect your device (such as a laptop or smartphone) to a Wi-Fi access point or router that is part of the LAN. This involves selecting the Wi-Fi network name (SSID), entering the correct password if security is enabled, and establishing a connection to access resources and the internet.
Wireless LAN (WLAN) and Wi-Fi are often used interchangeably, but technically, WLAN refers to any wireless local area network, whereas Wi-Fi specifically refers to wireless networking technology based on the IEEE 802.11 standards. In practical terms, when people refer to Wi-Fi, they are usually referring to a wireless LAN using Wi-Fi technology for connectivity.
