Unlicensed National Information Infrastructure (U-NII) devices operate in certain segments of the 5 GHz band and provide a wide array of high-data-rate mobile and fixed communications for individuals, businesses, and institutions, particularly for wireless local area networking –including Wi-Fi—and broadband access.

The rules for U-NII operation are set out in 47 CFR Part 15 Subpart E. In the First Report and Order in ET Docket No 13-49 adopted March 31, 2014, the Commission modified the rules for the U-NII-1 5.15-5.25 GHz band to allow certain access points to operate outdoors with up to 1 watt of conducted power. At the same time, the Commission took steps to ensure that incumbent systems are sufficiently protected from harmful interference. Specifically, Section 15.407 (j) provides a safeguard against harmful interference to incumbent systems in the 5.15-5.25 GHz U-NII-1 band by requiring accountability for large scale deployments of access points. Companies that deploy an aggregate total of more than one thousand outdoor access points within the band must submit a letter acknowledging that they may be required to take corrective actions should their devices cause harmful interference within the band.
