§ 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.
