In a Public Notice released September 14, 2011, DA 11-1534, OET announced that, beginning
September 19, 2011, it was conducting a 45-day public trial of Spectrum Bridge Inc.’s TV bands database
system. This trial allowed the public to access and test Spectrum Bridge’s database system to ensure that
it correctly identifies channels that are available for unlicensed TV bands devices, properly registers
facilities entitled to protection, and provides protection to authorized services and registered facilities as
specified in the rules. Participants were encouraged to report any inaccuracies or other issues with any
aspect of the database system to Spectrum Bridge.
Spectrum Bridge has provided a summary report on the trial of its TV bands database system to
OET that identifies: (1) problems reported and their disposition; and (2) descriptions of changes made to
the channel availability calculator or registration systems. We are requesting that interested parties
submit comments on the trial and this report. A copy of Spectrum Bridge’s report and its three
attachments is available on the Commission’s Electronic Comment Filing System (ECFS) at

database administrators (see Order in ET Docket No. 04-186, DA 11-131). OET will grant final approval

such decision through a Public Notice.
