§74.802. Frequency assignment. — Inbound Citations

(h) The Chief of the Office of Engineering and Technology is delegated authority to administer the database functions for unlicensed devices operating in the television broadcast bands (TV bands) as set forth in subpart H of part 15 of this chapter. The Chief is delegated authority to develop specific methods that will be used to designate TV bands database managers, to designate these database managers; to develop procedures that these database managers will use to ensure compliance with the requirements for database operations; to make determinations regarding the continued acceptability of individual database managers; and to perform other functions as needed for the administration of the TV bands databases. The Chief is also delegated authority jointly with the Chief of the Wireless Telecommunications Bureau to administer provisions of § 15.713(h)(8) of this chapter pertaining to the registration of event sites where large numbers of wireless microphones that operate on frequencies specified in § 74.802 of this chapter are used.

(e) The Chief of the Wireless Telecommunications Bureau is delegated authority jointly with the Chief of the Office of Engineering and Technology to administer provisions of § 15.713(h)(8) of this chapter pertaining to the registration of event sites where large numbers of wireless microphones that operate on frequencies specified in § 74.802 of this chapter are used.

(a) White space devices shall rely on a geolocation capability and database access mechanism to protect the following authorized service in accordance with the interference protection requirements of § 15.712: Digital television stations, digital and analog Class A, low power, translator and booster stations; translator receive operations; fixed broadcast auxiliary service links; private land mobile service/commercial radio service (PLMRS/CMRS) operations; offshore radiotelephone service; low power auxiliary services authorized pursuant to §§ 74.801 through 74.882 of this chapter, including licensed wireless microphones; MVPD receive sites; wireless medical telemetry service (WMTS); radio astronomy service (RAS); and 600 MHz service band licensees where they have commenced operations, as defined in § 27.4 of this chapter. In addition, protection shall be provided in border areas near Canada and Mexico in accordance with § 15.712(g).

(d) A request for special temporary authority shall specify a frequency band consistent with the provisions of § 74.802: Provided, That, in the case of events of wide-spread interest and importance which cannot be transmitted successfully on these frequencies, frequencies assigned to other services may be requested upon a showing that operation thereon will not cause interference to established stations: And provided further, In no case will operation of a low power auxiliary broadcast station be authorized on frequencies employed for the safety of life and property.

(c) Licensees of AM, FM, TV, and International broadcast stations; low power TV stations; and broadcast network entities may be authorized to operate low power auxiliary stations in the frequency bands set forth in § 74.802(a).

(f) Applications for the use of the bands allocated for TV broadcasting must specify the usual area of operation within which the low power auxiliary station will be used. This area of operation may, for example, be specified as the metropolitan area in which the broadcast licensee serves, the usual area within which motion picture and television producers are operating, or the location of the venue. Licenses issued to large venue owners or operators are specific to a single venue and authorize operation only at that venue. Because low power auxiliary stations operating in these bands will only be permitted in areas removed from existing co-channel TV broadcast stations, licensees have full responsibility to ensure that operation of their stations does not occur at distances less than those specified in § 74.802(b).

(5) The operating bandwidth shall not exceed 200 kilohertz, except that a wireless multichannel audio system must have an operating bandwidth not exceeding 6 megahertz in the TV bands or 4 megahertz in the 653-657 MHz band and must have a mode of operation in which it is capable of transmitting at least three audio channels per megahertz. For wireless multichannel audio systems operating in the TV bands, the 6 megahertz (or less) channel must fall entirely within a single TV channel (2-36) that is available for Part 74 LPAS use under § 74.802(b). The provisions of § 74.802(c) regarding frequency of operation within TV channels do not apply to wireless multichannel audio systems.
