§ 74.802   Frequency assignment.

   (a) Frequencies within the following bands may be assigned for use by low
   power auxiliary stations:

   26.100-26.480 MHz

   54.000-72.000 MHz

   76.000-88.000 MHz

   161.625-161.775 MHz (except in Puerto Rico or the Virgin Islands)

   174.000-216.000 MHz

   450.000-451.000 MHz

   455.000-456.000 MHz

   470.000-488.000 MHz

   488.000-494.000 MHz (except Hawaii)

   494.000-608.000 MHz

   614.000-698.000 MHz

   944.000-952.000 MHz

   (b)(1) Operations in the bands allocated for TV broadcasting are limited to
   locations at least 4 kilometers outside the protected contours of co-channel
   TV stations shown in the following table. These contours are calculated
   using the methodology in § 73.684 of this chapter and the R-6602 curves
   contained in § 73.699 of this chapter.
   Type of station Protected contour
   Channel Contour
   (dBu) Propagation curve
   Analog: Class A TV, LPTV,
   translator and booster Low VHF (2-6) 47 F(50,50)
       High VHF (7-13) 56 F(50,50)
       UHF (14-51) 64 F(50,50)
   Digital: Full service TV, Class A TV, LPTV, translator and booster Low VHF
   (2-6) 28 F(50,90)
       High VHF (7-13) 36 F(50,90)
       UHF (14-51) 41 F(50,90)

   (2)  Low  power auxiliary stations may operate closer to co-channel TV
   broadcast stations than the distances specified in paragraph (b)(1) of this
   section provided that their operations are coordinated with TV broadcast
   stations  that  could  be  affected by the low power auxiliary station
   operation. Coordination must be completed prior to operation of the low
   power auxiliary station.

   (c) Specific frequency operation is required when operating within the bands
   allocated for TV broadcasting.

   (1) The frequency selection shall be offset from the upper or lower band
   limits by 25 kHz or an integral multiple thereof.

   (2) One or more adjacent 25 kHz segments within the assignable frequencies
   may be combined to form a channel whose maximum bandwidth shall not exceed
   200 kHz.

   (d) Low power auxiliary licensees will not be granted exclusive frequency
   assignments.

   (e)  Clearing mechanisms for the 700 MHz Band. This section sets forth
   provisions  relating to the transition of low power auxiliary stations
   operating at 698-806 MHz (700 MHz band).

   (1) Any low power auxiliary station that operates at frequencies in the 700
   MHz band while transitioning its operations out of that band must not cause
   harmful interference and must accept interference from any commercial or
   public safety wireless licensees in the 700 MHz band.

   (2) Any low power auxiliary station that operates at frequencies in the 700
   MHz band will have until no later than June 12, 2010 to transition its
   operations completely out of the 700 MHz band, subject to the following.
   During this transition period, any commercial or public safety licensee in
   the 700 MHz band may choose one or both of the following voluntary methods
   to notify low power auxiliary stations:

   (i) Any commercial or public safety licensee in the 700 MHz band may notify
   the Commission that it has initiated or will be initiating operations on
   specified frequencies in a particular market(s) in the 700 MHz band. The
   wireless operations initiated by the commercial or public safety 700 MHz
   licensees may include system testing or trials. Following receipt of the
   notification, the Commission will issue a public notice providing that
   operators of low power auxiliary stations, including wireless microphones,
   in the 700 MHz band in those market(s) will be required to cease operations
   within 60 days after the Commission's notice is released.

   (ii) Any commercial or public safety licensee in the 700 MHz band may notify
   any low power auxiliary station users operating in the 700 MHz band that it
   has initiated or will be initiating operations on specified frequencies in
   the  market in which the low power auxiliary station is operating. The
   wireless operations initiated by the commercial or public safety 700 MHz
   licensees may include system testing or trials. Upon receipt of such notice,
   the low power auxiliary station in the affected market area must cease
   operation within 60 days.

   (iii)  In the event that both of these notice provisions in paragraphs
   (e)(2)(i) and (ii) of this section are used with respect to a particular low
   power auxiliary station, the low power auxiliary station will have to cease
   operations in the market(s) in accordance with whichever notice provides for
   earlier termination of its operations.

   (3) Notwithstanding this 60 day notice requirement, any low power auxiliary
   station that causes harmful interference to any commercial or public safety
   700 MHz licensee must cease operations immediately, consistent with the
   rules for secondary use.

   (f) Operations in 600 MHz band assigned to wireless licensees under part 27
   of this chapter. A low power auxiliary station that operates on frequencies
   in the 600 MHz band assigned to wireless licensees under part 27 of this
   chapter must cease operations on those frequencies no later than the end of
   the post-auction transition period as defined in § 27.4 of this chapter.
   During the post-auction transition period, low power auxiliary stations will
   operate on a secondary basis to licensees of part 27 of this chapter, i.e.,
   they must not cause to and must accept harmful interference from these
   licensees.
