Section 15.713 - [Effective until 11/18/2024] 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: (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 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 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);(v) Name of the individual or business that owns the device;(vi) Name of a contact person responsible for the device's operation;(vii) Address for the contact person;(viii) Email address for the contact person;(ix) Phone number for the contact person.(h)Mode II personal/portable and mobile device information to database.(1) A mobile device and a personal/portable device operating in Mode II shall provide the database its FCC Identifier (as required by § 2.926 of this chapter) and serial number as assigned by the manufacturer.(2) A personal/portable device operating in Mode II shall provide the database the device's geographic coordinates (latitude and longitude (NAD 83)).(3) A mobile device shall provide the database with the boundaries of the geo-fenced area in which it will operate.
