WLAN vs. WIFI — What's the Difference?

WLAN, short for Wireless Local Area Network, encompasses all types of wireless networks that provide connectivity within a localized area, such as homes, offices, or campuses. These networks use various wireless communication protocols to link devices without physical cables. Wi-Fi, on the other hand, is a specific technology and set of standards within the WLAN category, defined by the IEEE 802.11 family. It enables wireless communication between devices and a network, making it the most common form of WLAN used worldwide.

WLAN is a broad term that includes any network utilizing wireless communication to connect devices within a local area. This can include various technologies like Bluetooth, Zigbee, and others. Wi-Fi specifically refers to the implementation of WLAN using the IEEE 802.11 standards, known for providing high-speed internet access and robust connectivity.

While WLAN can be implemented using different frequencies and technologies depending on the use case, Wi-Fi typically operates on the 2.4 GHz and 5 GHz frequency bands. This distinction allows Wi-Fi to support a wide range of devices and applications, from simple data transfer to high-bandwidth activities like streaming and gaming.

WLANs can be set up using various methods and equipment, such as routers, access points, and network extenders. Wi-Fi networks, specifically, require compatible Wi-Fi routers and devices that adhere to the 802.11 standards to ensure proper communication and interoperability.

In terms of security, WLANs can incorporate various encryption methods to protect data, including WEP, WPA, and WPA2. Wi-Fi networks specifically use these encryption standards to secure connections and ensure data privacy between devices and the network.
