§  90.1319   Policies governing the use of the 3650-3700 MHz band.

   (a) Channels in this band are available on a shared basis only and will
   not be assigned for the exclusive use of any licensee.

   (b) Any base, fixed, or mobile station operating in the band must
   employ a contention-based protocol.

   (c) Equipment incorporating an unrestricted contention-based protocol
   (i.e. one capable of avoiding co-frequency interference with devices
   using all other types of contention-based protocols) may operate
   throughout the 50 megahertz of this frequency band. Equipment
   incorporating a restricted contention-based protocol (i.e. one that
   does not qualify as unrestricted) may operate in, and shall only tune
   over, the lower 25 megahertz of this frequency band.

   (d) All applicants and licensees shall cooperate in the selection and
   use of frequencies in the 3650-3700 MHz band in order to minimize the
   potential for interference and make the most effective use of the
   authorized facilities. A database identifying the locations of
   registered stations will be available at http://wireless.fcc.gov/uls .
   Licensees should examine this database before seeking station
   authorization, and make every effort to ensure that their fixed and
   base stations operate at a location, and with technical parameters,
   that will minimize the potential to cause and receive interference.
   Licensees of stations suffering or causing harmful interference are
   expected to cooperate and resolve this problem by mutually satisfactory
   arrangements.
