§ 25.214   Technical requirements for space stations in the Satellite Digital
Audio Radio Service and associated terrestrial repeaters.

   (a) [Reserved]

   (b) Each system authorized under this section will be conditioned upon
   construction, launch and operation milestones as outlined in § 25.144(b). The
   failure to meet any of the milestones contained in an authorization will
   result in its cancellation, unless such failure is due to circumstances
   beyond  the  licensee's  control or unless otherwise determined by the
   Commission upon proper showing by the licensee in any particular case.

   (c) Frequency assignments will be made for each satellite DARS system as
   follows:

   (1) Exclusive SDARS licenses are limited to the 2320-2345 MHz segment of the
   2310-2360 MHz allocated bandwidth for SDARS;

   (2) Two, 12.5 MHz frequency assignments are available for satellite DAR§ 
   2320.0-2332.5 MHz and 2332.5-2345.0 MHz;

   (3) Satellite DARS licensees may reduce their assigned bandwidth occupancy
   to provide telemetry beacons in their exclusive frequency assignments;

   (4)  Each  licensee may employ cross polarization within its exclusive
   frequency assignment and/or may employ cross polarized transmissions in
   frequency  assignments  of other satellite DARS licensees under mutual
   agreement with those licensees. Licensees who come to mutual agreement to
   use cross-polarized transmissions shall apply to the Commission for approval
   of the agreement before coordination is initiated with other administrations
   by the licensee of the exclusive frequency assignment; and

   (5) Feeder uplink networks are permitted in the following Fixed-Satellite
   Service frequency bands: 7025-7075 MHz and 6725-7025 MHz (101° W.L. orbital
   location only).

   (d) Power limit for SDARS terrestrial repeaters. (1) SDARS terrestrial
   repeaters must be operated at a power level less than or equal to 12-kW
   average EIRP, with a maximum peak-to-average power ratio of 13 dB.

   (2) SDARS repeaters are permitted to operate at power levels above 12-kW
   average EIRP, unless a potentially affected WCS licensee provides written
   notice that it intends to commence commercial service within the following
   365 days. Starting 180 days after receipt of such written notice, SDARS
   repeaters within the area notified by the potentially affected WCS licensee
   must be operated at a power level less than or equal to 12-kW average EIRP,
   with a maximum peak-to-average power ratio of 13 dB.

   (3) For the purpose of this section, a WCS licensee is potentially affected
   if  it is authorized to operate a base station in the 2305-2315 MHz or
   2350-2360 MHz bands within 25 kilometers of a repeater seeking to operate
   with a power level greater than that prescribed in paragraph (d)(1) of this
   section.
