Just about a year ago the FCC approved new White Space broadband rules governing the use of unlicensed spectrum, largely freed by the shift to digital television, for a new form of broadband with the potential for significant rural reach. This week the FCC announced that they'll soon be testing the database system they've created that will allow devices to check for nearby interference. These databases will be run by several companies including Google, and the FCC says their testing of this new system will occur between September 19 and November 2. The FCC has published their database test facility here, which users will be able to poke and prod for accuracy and other issues.
