Wi-Fi 7
What is Wi-Fi 7?
Wi-Fi 7The marketing name for IEEE 802.11be, introducing 320 MHz channels, 4K-QAM, and Multi-Link Operation, with WPA3 as the mandatory security baseline.
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.
