Office of Engineering and Technology Announces the Opening of Public Testing for
Google’s TV Band Database System Registration Procedures
ET Docket No. 04-186
The Commission’s Office of Engineering and Technology (OET) announces that on June 2, 2014,
it will commence a 45-day public trial of a new registration system for Google’s TV band database
system. TV band databases support the operation of unlicensed devices on unused spectrum in the TV
band (TV white space or “TVWS”). Currently, Spectrum Bridge Inc., another approved TV band
database administrator, is managing the registration of protected entities on Google's behalf. Google has
now developed its own protected facility registration procedures to replace its use of the Spectrum Bridge
procedures. This is a limited trial that is intended to allow the public to access and test Google’s new
registration procedures to ensure that those procedures properly register certain facilities entitled to
protection and that its modified database system provides protection to such registered facilities as
specified in the rules. We encourage all interested parties to test these new registration procedures and
provide appropriate feedback to Google.
The Commission’s Part 15 rules (47 C.F.R. § 15.701 et seq.) require that unlicensed TV band
devices contact an authorized database system to obtain a list of channels that are available for their
operation (i.e., channels not occupied by authorized radio services) at their individual locations and must
operate only on those channels. Such devices are required to provide their geographic location, by means
of a secure Internet connection, to a TV band database system authorized by the Commission. The
database will then return a list of the channels available for operation by a device at its reported location.
As part of its authorization process for TV band database systems, the Commission stated that
each database will be subject to a public trial period of not less than 45 days to ensure that the database is
providing accurate results before it is allowed to be made available for regular public use. Google’s new
protected entity registration procedures constitute a major modification of its database system and
therefore are subject to the Commission’s TV band database approval process, including the 45-day
public trial. OET has examined the new Google protected entity registration procedures facilities and
finds that those procedures are ready for trial testing by the public.
Trial Access and Details
Parties may participate in the trial by accessing Google’s TV band database test facility at:
https://www.google.com/get/spectrumdatabase/sandbox/. This website provides a description of the trial,
instructions for participation, details on use of the new registration procedures and database system,
access to the database’s various capabilities, and a link for providing comments and other feedback to
Google. The test facility will not be active before the date the trial is scheduled to commence.
During this trial, participants are encouraged to test:
the MVPD receive site (cable headend and satellite receive site) registration utility
the broadcast auxiliary temporary receive site registration utility
the fixed TV band device registration utility; and
the wireless microphone registration utility
the channel availability calculator to observe that protection is provided for registered
The trial is intended to ensure that each of these elements of Google’s modified database system is
working properly and providing the interference protection required under our rules.
In addition, participants are encouraged to report any inaccuracies or provide comments on issues
with any other aspect of the registration system and the database system as modified to Google through
the response facility on the trial’s website. Google will respond, as appropriate, to such reports and
comments with an explanation and notification of any responsive actions it may take, as appropriate.
During the trial, Google may apply any corrective measures it determines are needed and will advise
participants of such measures through the trial’s website.
As indicated above, the trial of the modified Google database system is currently scheduled to last
for 45 days and will therefore end on July 17, 2014. However, if the results of the trial indicate that
additional testing is necessary, OET may extend the trial period.
After the close of the trial, Google will provide a summary report to OET that identifies: 1)
problems reported and their disposition; and 2) descriptions of changes made to the registration
procedures or channel availability calculator. Once Google submits its report, OET will provide a short
period of time for interested parties to submit comments on the report. Note that the successful
performance of the modified database system through this trial is only one element in OET’s evaluation
of a system for approval to operate. Other requirements for TV band database systems are set forth in 47
C.F.R. 15.701 et seq. and OET’s January 26, 2011 Order on TV band database administrators (see Order
in ET Docket No. 04-186, DA 11-131). OET will grant final approval for Google to operate its modified
database system with certified TV band 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
The FCC rules require that TV band database systems protect the following radio services: 1)
broadcast television stations (including full power, TV translator, low power TV, and Class A stations);
2) fixed broadcast auxiliary service (BAS) links (both permanent fixed and temporary sites); 3) receive
sites (and received channels) of TV translator, low power TV, Class A TV stations, and multichannel
video programming distributors (MVPDs) (collectively “receive sites”); 4) private land mobile radio
service and commercial mobile radio service operations; 5) offshore radio telephone service operations;
6) radio astronomy operations at specific sites; and 7) low power auxiliary service operations (principally
licensed and certain approved unlicensed wireless microphone venue sites). Except for temporary BAS
links, receive sites, locations where licensed wireless microphones are used, and approved unlicensed
wireless microphone venues, the necessary information for TV band databases to provide protection from
unlicensed devices is either extracted by the database administrators from the Commission’s databases or
is specified in the rules. Parties responsible for facilities for which information is contained in the
Commission’s records or provided in the rules do not need to take any action to obtain protection from
TV band devices.
Parties responsible for temporary BAS links, receives sites, and wireless microphone uses must
specifically register their sites to receive protection from TV band devices. Google’s modified database
system provides new registration procedures for these facilities. These new registration capabilities are
available for examination through Google’s database test facility at:
https://www.google.com/get/spectrumdatabase/sandbox/. The rules provide that use of unlicensed
wireless microphone may be registered for protection in the TV band databases only at certain qualifying
venues and if pre-approved by the Commission. (Such requests may be made through the Commission’s
Universal Licensing System (ULS) at http://www.fcc.gov/uls/login). For purposes of this trial, Google,
with OET’s approval, has implemented a test registration capability for registration of venues where
unlicensed wireless microphones are used that does not require that registrations be pre-approved by the
Commission; this test registration capability is available through Google’s database test facility.
We encourage parties responsible for MVPD receive sites, licensed wireless microphone
operations, venues where large numbers of unlicensed wireless microphones are used, and temporary
BAS links to enter trial registrations and make use of these capabilities in their testing of Google’s
modified database. Registrations for MVPD receive sites, sites where licensed wireless microphones are
used, venues where large numbers of wireless microphones are used, and temporary BAS links that are
made during the trial period will be deleted by Google after the trial.
Parties can register their temporary BAS links, receive sites, and sites where licensed wireless
microphones are used with Google’s operational database system now through its use of the Spectrum
Bridge registration procedures incorporated therein. Existing registrations and new registrations made
through that database will be included, as appropriate, in Google’s modified database system after that
system is approved and implemented for operation with the new registration procedures. Note that
registrations made with Google’s operational database are shared with the other databases and
registrations that expire will not remain in the TV band databases. 1 New registrations entered into
Google’s current operational database during the trial or its modified database after the trial will be
communicated to, and included in, the other databases.
