Sec.  25.257   Special requirements for operations in the band 29.1–29.25 GHz
between NGSO MSS and 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  Sec. 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  Sec. 25.203
   and  Sec. 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 connection, any single NGSO MSS operator shall only
   identify one feeder link earth station complex protection zone in each
   category identified in  Sec. 101.147(c)(2) of this chapter until the other NGSO
   MSS operator has been given an opportunity to select a location from the
   same category.
