Office of Engineering and Technology Laboratory Division Knowledge Database (KDB)

Welcome to the OET Laboratory Division Knowledge Database (KDB). The FCC Office of Engineering and Technology (OET) publishes equipment authorization procedures and measurement guidance in the form of FCC Public Notices and Knowledge Database (KDB) publications. The staff guidance provided in the KDB is intended to assist the public in following Commission requirements and does not constitute rules. Accordingly, the guidance is not binding on the Commission and will not prevent the Commission from making a different decision in any matter that comes to its attention for resolution.

The Basic KDB Search is a full text search and the Advanced KDB Search allows for input of multiple search criteria. The KDB Publication Number search is a quick search for a specific publication. We hope that your visit is both timely and useful.
