The Universal Licensing System (ULS) and Antenna System Registration (ASR) databases offer public access downloads for specific wireless radio services.
These downloads are available as zip files in both weekly transactions and in a six day sequence of transactions (daily).

NOTE: The 800 MHz Vacated Spectrum Files are not updated on a daily or weekly basis. Look for Public Notices regarding file availability updates.
* Some of the database files are very large.
