WLAN (Wi-Fi) Explained

The WLAN (Wi-Fi) Explained series is comprised of 22 short videos describing various aspects of wireless LAN (Wi-Fi) technology. The series presents different revisions of the 802.11 standard for WLAN and briefly introduces MathWorks WLAN Toolbox. The videos contain valuable information on physical layer (PHY) and MAC layer of Wi-Fi standards. They also explain latest Wi-Fi standards including Wi-Fi 5 (802.11ac), Wi-Fi 6 (802.11ax), and Wi-Fi 7 (802.11be), respectively.
