Wi-Fi

IEEE 802.11 wireless networking, providing shared medium access with its own authentication, RF design and roaming considerations.

IntermediateUpdated 2026-09-01

Overview

Wi-Fi performance is an RF design problem: channel planning, cell size, band steering and client capability matter more than access point count. Wi-Fi 6 and 6E add OFDMA and, in 6 GHz, far more clean spectrum.

Enterprise authentication uses WPA2/WPA3 Enterprise with 802.1X and EAP TLS, issuing per user or per device credentials rather than a shared passphrase.

Security considerations

  • Use WPA3 Enterprise with certificate based EAP TLS where possible; avoid shared PSKs on corporate SSIDs.
  • Separate guest traffic into an isolated VLAN with client isolation and its own egress policy.
  • Monitor for rogue and evil twin access points.
