The Unlicensed National Information Infrastructure radio band is part of the radio spectrum used by IEEE-802.11a devices and by many wireless ISPs. It operates over two ranges:

U-NII Indoor: 5.15-5.35 GHz
U-NII Low: 5.725-5.825 GHz

U-NII is an FCC regulatory domain for 5-GHz wireless devices.

U-NII power limits are defined by the United States 47 CFR 15.407 regulations. Individual countries' use of the bands designated in these sections may differ due to variations in national radio regulations.

The European HiperLAN standard operates in the U-NII band.

In the USA, CFR Title 47 Part 15 (revised in 2004) describes the regulation of the U-NII bands.
