§ 15.713 White space database.
(a) Purpose. The white space database serves the following functions:
(1) To determine and provide to a white space device, upon request, the
available channels at the white space device's location in the TV
bands, the 600 MHz guard bands, the 600 MHz duplex gap, the 600 MHz
service band, and channel 37. Available channels are determined based
on the interference protection requirements in § 15.712. A database must
provide fixed and Mode II personal portable white space devices with
channel availability information that includes scheduled changes in
channel availability over the course of the 48 hour period beginning at
the time the white space devices make a re-check contact. In making
lists of available channels available to a white space device, the
white space database shall ensure that all communications and
interactions between the white space database and the white space
device include adequate security measures such that unauthorized
parties cannot access or alter the white space database or the list of
available channels sent to white space devices or otherwise affect the
database system or white space devices in performing their intended
functions or in providing adequate interference protections to
authorized services operating in the TV bands. In addition, a white
space database must also verify that the FCC identifier (FCC ID) of a
device seeking access to its services is valid; under this requirement
the white space database must also verify that the FCC ID of a Mode I
device provided by a fixed or Mode II device is valid. A list of
devices with valid FCC IDs and the FCC IDs of those devices is to be
obtained from the Commission's Equipment Authorization System.
(2) To determine and provide to an unlicensed wireless microphone user,
upon request, the available channels at the microphone user's location
in the 600 MHz guard bands, the 600 MHz duplex gap, and the 600 MHz
service band. Available channels are determined based on the
interference protection requirements in § 15.236.
(3) To register the identification information and location of fixed
white space devices and unlicensed wireless microphone users.
(4) To register protected locations and channels as specified in
paragraph (b)(2) of this section, that are not otherwise recorded in
Commission licensing databases.
(b) Information in the white space database. (1) Facilities already
recorded in Commission databases. Identifying and location information
will come from the official Commission database. These services
include:
(i) Digital television stations.
(ii) Class A television stations.
(iii) Low power television stations.
(iv) Television translator and booster stations.
(v) Broadcast Auxiliary Service stations (including receive only
sites), except low power auxiliary stations.
(vi) Private land mobile radio service stations.
(vii) Commercial mobile radio service stations.
(viii) Offshore radiotelephone service stations.
(ix) Class A television station receive sites.
(x) Low power television station receive sites.
(xi) Television translator station receive sites.
(2) Facilities that are not recorded in Commission databases.
Identifying and location information will be entered into the white
space database in accordance with the procedures established by the
white space database administrator(s). These include:
(i) MVPD receive sites.
(ii) Sites where low power auxiliary stations, including wireless
microphones and wireless assist video devices, are used and their
schedule for operation.
(iii) Fixed white space device registrations.
(iv) 600 MHz service band operations in areas where the part 27 600 MHz
service licensee has commenced operations, as defined in § 27.4 of this
chapter.
(v) Locations of health care facilities that use WMTS equipment
operating on channel 37 (608-614 MHz).
(c) Restrictions on registration. (1) Television translator, low power
TV and Class A station receive sites within the protected contour of
the station being received are not eligible for registration in the
database.
(2) MVPD receive sites within the protected contour or more than 80
kilometers from the nearest edge of the protected contour of a
television station being received are not eligible to register that
station's channel in the database.
(d) Determination of available channels. The white space database will
determine the available channels at a location using the interference
protection requirements of § 15.712, the location information supplied
by a white space device, and the data for protected stations/locations
in the database.
(e) White space device initialization. (1) Fixed and Mode II white
space devices must provide their location and required identifying
information to the white space database in accordance with the
provisions of this subpart.
(2) Fixed and Mode II white space devices shall not transmit unless
they receive, from the white space database, a list of available
channels and may only transmit on the available channels on the list
provided by the database.
(3) Fixed white space devices register and receive a list of available
channels from the database by connecting to the Internet, either
directly or through another fixed white space device that has a direct
connection to the Internet.
(4) Mode II white space devices receive a list of available channels
from the database by connecting to the Internet, either directly or
through a fixed or Mode II white space device that has a direct
connection to the Internet.
(5) A fixed or Mode II white space device that provides a list of
available channels to a Mode I device shall notify the database of the
FCC identifier of such Mode I device and receive verification that that
FCC identifier is valid before providing the list of available channels
to the Mode I device.
(6) A fixed device with an antenna height above ground that exceeds 30
meters or an antenna height above average terrain (HAAT) that exceeds
250 meters shall not be provided a list of available channels. The HAAT
is to be calculated using computational software employing the
methodology in § 73.684(d) of this chapter.
(f) Unlicensed wireless microphone database access. Unlicensed wireless
microphone users in the 600 MHz band may register with and access the
database manually via a separate Internet connection. Wireless
microphone users must register with and check a white space database to
determine available channels prior to beginning operation at a given
location. A user must re-check the database for available channels if
it moves to another location.
(g) Fixed white space device registration. (1) Prior to operating for
the first time or after changing location, a fixed white space device
must register with the white space database by providing the
information listed in paragraph (g)(3) of this section.
(2) The party responsible for a fixed white space device must ensure
that the white space device registration database has the most current,
up-to-date information for that device.
(3) The white space device registration database shall contain the
following information for fixed white space devices:
(i) FCC identifier (FCC ID) of the device;
(ii) Manufacturer's serial number of the device;
(iii) Device's geographic coordinates (latitude and longitude (NAD
83));
(iv) Device's antenna height above ground level (meters);

(h) Mode II personal/portable device information to database. A
personal/portable device operating in Mode II shall provide the
database its FCC Identifier (as required by § 2.926 of this chapter),
serial number as assigned by the manufacturer, and the device's
geographic coordinates (latitude and longitude (NAD 83)).
(i) Unlicensed wireless microphone registration. Unlicensed wireless
microphone users in the 600 MHz band shall register with the database
prior to operation and include the following information:
(1) Name of the individual or business that owns the unlicensed
wireless microphone
(2) Address for the contact person
(3) Email address for the contact person
(4) Phone number for the contact person; and

translator and booster stations, including stations in Canada and
Mexico that are within the border coordination areas as specified in
§ 73.1650 of this chapter (a white space database is to include only TV
station information from station license or license application
records. In cases where a station has records for both a license
application and a license, a white space database should include the
