Sec.  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.
