  §  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 duplex gap, the 600 MHz service band, and 608-614
   MHz (channel 37). Available channels are determined based on the
   interference protection requirements in § 15.712. A database must
   provide fixed, mobile, 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 recheck 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, the 600 MHz duplex gap,
   the 600 MHz service band, and 608-614 MHz (channel 37). 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 the
   requirement in this paragraph (a)(1) 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, mobile, 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, mobile, 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 and mobile 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. Fixed devices must also register
   with the database in accordance with paragraph (g) of this section.

   (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 generally, or 500 meters in less congested areas 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
