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,

image02-00.jpg612x792

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

facilities

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

Notice.

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

2

image03-00.jpg612x792

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.

The TV band database systems are the subject of a docketed proceeding, ET Docket No. 04-186,

and responses to the trial of Google’s database system conducted pursuant to this public notice may be

filed with the Commission at any time using the FCC’s Electronic Comment Filing System (ECFS) as

described below. The FCC has implemented a simplified interface for ECFS to facilitate consumer

comment. Documents filed on ECFS may be accessed and reviewed on that system, which contains

copies of written submissions and summaries of oral submissions regarding the white spaces proceeding.

Pursuant to sections 1.415 and 1.419 of the Commission’s rules, 47 CFR §§ 1.415, 1.419,

interested parties may file comments and reply comments on the trial of Google’s database system at any

time during and after the trial period. Comments may be filed using the Commission’s Electronic

Comment Filing System (ECFS). See Electronic Filing of Documents in Rulemaking Proceedings, 63 FR

24121 (1998).

1 Thus far, OET has approved the TV band databases of Spectrum Bridge, Inc., iconectiv (formerly

Telcordia Technologies, Inc.), Key Bridge Global, LLC, and Google, Inc. for operation to provide service

to devices.
