Reply comments Date: June 20, 2013
45-day public trial of Keybridge Global Inc.’s (Keybridge’s) TV bands database system that was
completed on April 24, 2013. This database system is designed and intended to support the operation of
low power unlicensed transmitting devices on unoccupied spectrum within the broadcast television bands
(TV bands). This unoccupied spectrum is commonly known as the TV “White Spaces.”
In a Public Notice released March 4, 2013, DA 13-328, OET announced that, beginning March
11, 2013, it was conducting a 45-day public trial of Keybridge’s TV bands database system. This trial
allowed the public to access and participate in the testing of the Keybridge 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 Keybridge.
Keybridge has provided a summary report on the trial of its TV bands database system to OET.
This summary report identifies: 1) problems reported and their disposition and 2) descriptions of changes
made by Keybridge to the channel availability calculator or registration systems during the trial period.
We are requesting that interested parties submit comments on the trial and this report. A copy of
Keybridge’s summary report and its three attachments is available on the Commission’s Electronic
Comment Filing System (ECFS) at

The successful performance of the database system through this trial is only one element in the
Commission’s evaluation of a system for approval to operate. Other requirements for TV bands database
systems are set forth in 47 C.F.R. 15.701 et seq. and OET’s January 26, 2011, Order on TV bands
database administrators (see Order in ET Docket No. 04-186, DA 11-131). OET will grant final approval
for Keybridge to operate its database system with certified TV bands devices once it determines that the
system complies with all of the applicable rules and requirements. The public will be informed of such
decision through a Public Notice.
