Wi-Fi 7 (802.11be Extremely High Throughput) extends Wi-Fi 6/6E with 320 MHz channels in the 6 GHz band, 4K-QAM modulation, and Multi-Link Operation (MLO), which lets a client use multiple bands simultaneously. From a security perspective, Wi-Fi 7 mandates WPA3-SAE (Simultaneous Authentication of Equals) and 802.11w Protected Management Frames, eliminating WPA2-PSK as a certified option. MLO introduces new key-derivation and roaming considerations: keys are bound to the MLD (multi-link device) rather than to a single radio, so misconfiguration can bypass per-link controls. Operators should pay attention to enterprise-grade authentication (802.1X/EAP), client driver maturity, and detection for downgrade or rogue-AP attacks specific to MLO.

Defences for Wi-Fi 7 typically combine technical controls and operational practices, as detailed in the full definition above.

Common alternative names include: 802.11be, Extremely High Throughput Wi-Fi.
