Wi-Fi (WLAN)
Technological development of WLAN and Wi-Fi according to IEEE 802.11.
WLAN (Wireless Local Area Network) refers to a wireless network based on radio technology. It is a generic term for wireless networks whose technical foundations are defined in the IEEE standards IEEE 802.11.
Technology
A standard for seamless communication.
The term Wi-Fi, on the other hand, is a protected brand name of the Wi-Fi Alliance. This organization ensures that devices from different manufacturers that are based on the IEEE 802.11 standard can communicate seamlessly with each other. Certifications such as Wi-Fi Certified, WPA3, Wi-Fi 6/6E or Wi-Fi 7 ensure that end devices meet certain requirements for security, performance and compatibility.
