In the MSS/ATC proceeding, we did not analyze the potential for overload interference from ATC base stations to adjacent band satellite receivers. For example, licensees can ``down-tilt'' their station antennas or locate their base stations far enough from one another, spectrally and geographically, to avoid interference. See 47 C.F.R. § 25.252(c)(2). CTIA Comments to AWS Third NPRM at 3. See infra ¶ 111. If base station transmissions are prohibited from the 2020-2025 MHz band, there would be no possibility of ``base-to-base'' interference occurring to ATC base stations receiving in the 2000-2020 MHz band.

Furthermore, TerreStar asserts that the technical rules pertaining to 2 GHz ATC base station operation in Paragraphs (2), (3), (5), and (8) of Section 25.252(a) were adopted to prevent overloading of highly sensitive receivers that Boeing, a former 2 GHz MSS licensee, planned to deploy with a 2 GHz MSS system that was never implemented.

  • the information specified and the process outlined in Part 101 of our rules are adequate for coordination between FS operations and satellite operations and do not need modification. 52. We are revising here some of the Part 25 coordination rules for satellite operations to accommodate new NGSO FSS systems.123 The Report and Order in IB Docket No. 95-117 removed Sections 25.252-25.256 from our rules. Those sections specified the method for determining certain necessary coordination information such as coordination distances, rain scatter coordination distances, permissible interference levels and other coordination parameters.124 The Commission found that because the international coordination procedures contained in Appendix S7 of the ITU RR changed frequently, it would simply reference Appendix S7 in our rules. Therefore, we amend
