UNII (Unlicensed National Information Infrastructure) er frekvensbånd, som er anvendt af fx Wi-Fi5, Wi-Fi 6 og Wi-Fi 6E rlan-udstyr og af mange trådløse internetudbydere.

UNII er en USA FCC regulatorisk domæne for 5-7 GHz trådløst udstyr. Den europæiske HiperLAN standard opererer i UNII-båndet.

UNII-bånd udgøres af flere dele:
