§  101.1421   Coordination of adjacent area MVDDS stations.

   (a) MVDDS licensees in the 12.2-12.7 GHz band are required to develop
   sharing and protection agreements based on the design and architecture
   of their systems, in order to ensure that no harmful interference
   occurs between adjacent geographical area licensees. MVDDS licensees
   shall:

   (1) Engineer systems to be reasonably compatible with adjacent and
   co-channel operations in the adjacent areas on all its frequencies; and

   (2) Cooperate fully and in good faith to resolve interference and
   transmission problems that are present on adjacent and co-channel
   operations in adjacent areas.

   (b) Harmful interference to public safety stations, co-channel MVDDS
   stations operating in adjacent geographic areas, and stations operating
   on adjacent channels to MVDDS stations is prohibited. In areas where
   the DMAs are in close proximity, careful consideration should be given
   to power requirements and to the location, height, and radiation
   pattern of the transmitting and receiving antennas. Licensees are
   expected to cooperate fully in attempting to resolve problems of
   potential interference before bringing the matter to the attention of
   the Commission.

   (c) Licensees shall coordinate their facilities whenever the facilities
   have optical line-of-sight into other licensees' areas or are within
   the same geographic area. Licensees are encouraged to develop
   operational agreements with relevant licensees in the adjacent
   geographic areas. Incumbent public safety POFS licensee(s) shall retain
   exclusive rights to its channel(s) within the relevant geographical
   areas and must be protected in accordance with the procedures in
   § 101.103. A list of public safety incumbents is attached as Appendix I
   to the Memorandum Opinion and Order and Second Report and Order, Docket
   98-206, released May 23, 2002. Please check with the Commission for any
   updates to that list.
