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.
