Office of Engineering and Technology Seeks Comment on Microsoft Corporation Proposalto be Designated as a TV Bands Device Database Administrator
ET Docket No. 04-186

Technology (OET) seeking designation as a TV bands device database administrator under Part 15 of the
Commission's rules.1 By this Public Notice, we invite interested parties to file comments on Microsoft
On September 23, 2010, the Commission adopted a Second Memorandum Opinion and Order
(Second MO&O) in ET Docket No. 04-186 that revised the rules for unlicensed wireless devices that can
operate in broadcast television spectrum at locations where that spectrum is unused by licensed services.2
This unused TV spectrum is commonly referred to as television "white spaces." The rules allow for the
use of unlicensed TV bands devices in the unused spectrum to provide broadband data and other services
for consumers and businesses.
To prevent interference to authorized users of the TV bands, TV bands devices must include a
geo-location capability and the capability to access a database that identifies incumbent uses entitled to
interference protection, including, for example, full power and low power TV stations, broadcast
auxiliary point-to-point facilities, PLMRS/CMRS operations on channels 14-20, and the Offshore
Radiotelephone Service.3 The database will inform a TV bands device which TV channels are vacant
and can be used at its location.4 The database also will be used to register the locations of fixed TV
bands devices and the protected locations and channels of incumbent services that are not recorded in

2010. An Erratum correcting certain text and amendments to the rules in the Second Memorandum Opinion and
Order was released by the Commission's Office of Engineering and Technology on October 19, 2010.
3 See 47 C.F.R. 15.711. The rules also contain provisions for devices that rely on spectrum sensing to determine
available channels. See 47 C.F.R. 15.717.
4 See 47 C.F.R. 15.713(a)-(b).
Commission databases.5 The rules state that the Commission will designate one or more entities to
administer a TV bands database.6
The Office of Engineering and Technology (OET) released a public notice on November 25,
2009 inviting entities interested in being designated as a TV bands database administrator to file
proposals with the Commission and inviting comments on the proposals.7 The notice requested that
entities address how the basic components of a TV band database(s) as required by the Commission's
rules would be satisfied--i.e., a data repository, a data registration process, and a query process--and
whether the entity sought to provide all or only some of these functions and affirm that the database
service will comply with all of the applicable rules. Nine parties filed proposals in response to this
On January 26, 2011, OET issued an order designating all nine parties that filed proposals as TV
bands database administrators, subject to certain conditions. Specifically, the administrators were
required to: 1) supplement their initial filings to show how they will comply with the rule changes
adopted in the Second MO&O, 2) attend workshops conducted by OET to address the operation of the
databases to ensure consistency and compliance with the rules, 3) cooperate with any steps OET deems
necessary to ensure compliance with the rules, and 4) agree that they will not use their capacity as a
database manager to engage in any discriminatory or anti-competitive practices or any practices that may
compromise the privacy of users. In addition, each administrator's database will be subject to a trial
period of not less than 45 days before it is allowed to be made available for actual use by TV bands
devices to allow interested parties an opportunity to check that the database is providing accurate results.
OET has conducted two workshops since the release of the January 26, 2011 order.9
Microsoft's proposal addresses the questions in the November 25, 2009 public notice that invited
proposals from parties seeking to be designated as database administrators. In addition, Microsoft
provided information to show that it complies with the rule changes adopted in the Second MO&O and
states that it will comply with the other three conditions in the January 26, 2011 order that conditionally
designated the nine database administrators. We note that Microsoft representatives attended both of
OET's database administrator workshops.

of the TV stations whose signals they receive; the locations where authorized wireless microphones and other low
power auxiliary devices are used on a regular or scheduled basis).

7 See "Office of Engineering and Technology Invites Proposals from Entities Seeking to be Designated TV Band
Device Database Managers," Public Notice, DA 09-2479, ET Docket No. 04-186, rel. Nov. 25, 2009. The
information requested in the Public Notice was based on rules for TV bands databases and administrators adopted
in the Second Report and Order and Memorandum Opinion and Order (Second Report and Order) in ET Docket
No. 04-186, 23 FCC Rcd 16807 (2008).

LLC and LS Telcom), Key Bridge Global LLC, Neustar Inc., Spectrum Bridge Inc., Telcordia Technologies, and
Airity, Inc. (formerly WSdb LLC).
