§ 25.257   Special requirements for NGSO MSS operations in the 29.1-29.25 GHz
band regarding LMDS.

   (a) Non-geostationary Mobile-Satellite Service (NGSO MSS) operators
   shall be licensed to use the 29.1-29.25 GHz band for Earth-to-space
   transmissions from feeder link earth station complexes. A “feeder link
   earth station complex” may include up to three (3) earth station
   groups, with each earth station group having up to four (4) antennas,
   located within a radius of 75 km of a given set of geographic
   coordinates provided by a NGSO MSS licensees or applicants pursuant to
   § 101.147.

   (b) A maximum of seven (7) feeder link earth station complexes in the
   contiguous United States, Alaska and Hawaii may be placed into
   operation, in the largest 100 MSAs, in the band 29.1-29.25 GHz in
   accordance with § 25.203 and § 101.147 of this chapter.

   (c) One of the NGSO MSS operators licensed to use the 29.1-29.25 GHz
   band may specify geographic coordinates for a maximum of eight feeder
   link earth station complexes that transmit in the 29.1-29.25 GHz band.
   The other NGSO MSS operator licensed to use the 29.1-29.25 GHz band may
   specify geographic coordinates for a maximum of two feeder link earth
   station complexes that transmit in the 29.1-29.25 GHz band.

   (d) Additional NGSO MSS operators may be licensed in this band if the
   additional NGSO MSS operator shows that its system can share with the
   existing NGSO MSS systems.

   (e) All NGSO MSS operators shall cooperate fully and make reasonable
   efforts to identify mutually acceptable locations for feeder link earth
   station complexes. In this regard, any single NGSO MSS operator may
   identify only one feeder-link earth station complex protection zone in
   each category identified in § 101.147(y)(2) of this chapter until the
   other NGSO MSS operator has been given an opportunity to select a
   location from the same category.
