The Commission initially revised the rules for U-NII devices in 2014 (FCC 14-30, ET Docket No. 13-49). Subsequently, the Commission updated some of the rules for devices operating in the U-NII-3 band on March 2, 2016 (FCC 16-24, ET Docket No. 13-49; referred to in this document as New Rules). These rules became effective on May 6, 2016.

• All new devices or already approved devices seeking to add operations under Part 15 Subpart E must meet the requirements of the latest rules.
• Permissive changes will not be permitted for devices approved under the Old Rules, unless they meet the requirements of the New Rules.
