Description:  TITLE: Unlicensed White Space Device Operations in the Television Bands

  addressing pending issues associated with white space devices. These actions will provide additional 
certainty to whit e space device users and manufacturers to enable unlicensed white space devices 
to operate efficiently while protecting other spectrum users. In the Report and Order the Commission 
adopts rules specifying the database re -check interval for the new categori es of mobile and 
narrowband white space devices established in 2020. In the Order on Reconsideration, the 
Commission dismisses in part and, on alternative and independent grounds, denies a petition for 
reconsideration of two rule changes for white space de vices operating in the broadcast television 
(TV) bands. In the Memorandum Opinion and Order, the Commission declines to modify the rules to 
permit white space databases to use more complex terrain -based models to determine the available 
frequencies for whi te space devices and will instead continue to rely on the simpler established model 
that has worked reliably to prevent interference to TV and other protected services.  
Effective 21 June 2023.  
This final rule and previous actions notified under the symbol G/TBT/N/USA/1597  are identified by 
Docket Nos. 20 -36 and 14 -165; FCC 20 -17 and 23 -24. Additional information on the final rule is 
accessible from the FCC's Electronic Doc ument Management System ( EDOCS ) at
