Office of Engineering and Technology Requests Comment on the Public Trial

of Google, Inc.’s TV Band Database System Registration Procedures

ET Docket No. 04-186

Comments Date: August 13, 2014

Reply comments Date: August 19, 2014

The Commission’s Office of Engineering and Technology (OET) is requesting comment on the

45-day public trial of a new system of registration procedures for Google Inc.’s (Google’s) TV bands

database system that was completed on July 17, 2014. Google’s TV bands database system is designed

and intended to support the operation of low power unlicensed transmitting devices on unoccupied

spectrum within the broadcast television spectrum (TV band). This unoccupied spectrum is commonly

known as the TV “white spaces.” As part of their operations, TV white space database administrators,

including Google, are required to provide for registration in their databases of certain facilities using the

TV band that are to be provided protection from unlicensed devices and whose operating information is

not available from the FCC databases. Currently, Spectrum Bridge, another approved TV band database

administrator, is processing the registration of these protected facilities on Google’s behalf.

In a Public Notice released May 28, 2014, DA 14-720, OET announced that, beginning June 2,

2014, it was conducting a 45-day public trial of a new registration system was developed by Google and

is to be used with its TV band database system. This new registration system will replace the Google

database system’s current reliance on the Spectrum Bridge system for processing registration requests.

The 45-day trial allowed the public to access and participate in the testing of Google’s new registration

system to ensure that the system properly registers facilities entitled to protection and that Google’s

database system as modified to incorporate its new registration system provides protection to such

facilities as specified in the Commission’s rules. Participants were encouraged to report any inaccuracies

or other issues with any aspect of the database system to Google.

Google has provided a summary report on the trial of its new registration procedures and

modified database system to OET. This summary report identifies: 1) problems reported and their

disposition and 2) descriptions of changes made by Google to its new registration procedures or its

channel availability calculator during the trial period. We are requesting that interested parties submit

comments on the trial and this report. A copy of Google’s summary report is available on the

Commission’s Electronic Comment Filing System (ECFS) at:

Summary Report:


The Commission’s 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 (regular licensed and temporary); 3) receive

sites (and received channels) of TV translator, low power TV, and Class A TV stations and multichannel

video programming distributors (MVPDs); 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 MVPD receive sites, sites where licensed

wireless microphones are used, and approved unlicensed wireless microphone venues, the necessary data

and information for protection of the above facilities will either be extracted by Google from the

Commission’s databases or are specified in the rules. Operators of 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.

Operators of MVPD receive sites, wireless microphones users, and operators of temporary BAS

links must specifically register their sites with a TV bands database to receive protection from TV band

devices.1 Google’s modified database system provides a registration capability for these facilities that

replaces its current arrangement whereby its database uses registration procedures provided by Spectrum

Bridge. Those new registration procedures will be available for use with its database once OET grants

Google final approval to operate its database with those procedures. The rules also provide that

responsible parties may request that the Commission approve registrations for protection of venues where

unlicensed wireless microphones are used (such requests may be made through the Commission’s

Universal Licensing System (ULS) at Such requests for registration will

first be made available for public comment, and the Commission will subsequently review them for


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 not be transferred to its operational database. Parties are still able to register their

MVPD receive sites, sites where licensed wireless microphones are used, and temporary BAS links with

Google’s current database using the Spectrum Bridge registration procedures. They will be able to

register those facilities in Google’s modified database system once general operation of that system for

use by TV band devices is approved and implemented. Registrations made with the current Google

database system that have not expired as of the date when the modified database is approved for operation

will be included in the modified database.

The 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 bands database administrators (see Order in ET Docket No. 04-

186, DA 11-131). OET will grant final approval for Google to operate its database system as modified

with its new registration 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.

1 The TV band databases are required to exchange registration records such that a registration made with

any given database will also be transferred to and included in all of the other databases. A protected

entity therefore needs to register its facility with only a single database to obtain protection from all of the

databases. Thus far, OET has approved the TV band databases of Spectrum Bridge, Inc., iconnectiv,

Google, Inc., and Keybridge Global, LLC. for operation to provide service to devices.



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

186, and comments and reply comments addressing the trial of Google’s new registration for its TV band

database system must be filed in that proceeding using the FCC’s ECFS as described below. A simplified

interface for ECFS has been implemented 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.
