  Sec.  101.509   Interference protection criteria.

   (a) As a condition for use of frequencies in this service each licensee is
   required to:

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

   (2)  Cooperate  fully  and in good faith to resolve whatever potential
   interference and transmission security problems may be present in adjacent
   and co-channel operations.

   (b) All harmful interference to other users of co-channel and adjacent
   channel use in the same or adjacent geographical area are prohibited. In
   areas where Economic Areas are in close proximity, careful consideration
   should be given to minimum 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) Licensee 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 same or adjacent areas. Incumbent SMSA
   licensee(s) shall retain exclusive rights to its channel(s) within its SMSA
   and must be protected.

   (d) Licensees shall comply with the appropriate coordination agreements
   between  the United States and Canada and the United States and Mexico
   concerning  cross-border sharing and use of the 24 GHz bands which may
   require using channels pairs in accordance with the table in  Sec. 101.147(r)(9).

   (e) The Commission recommends that coordination is not necessary if the
   power flux density (pfd) at the boundary of the relevant adjacent area is
   lower than –114 dBW/m^2 in any 1 MHz. This value can be changed and agreed
   upon by both coordinating parties. Licensees should be able to deploy with a
   pfd up to –94 dBW/m^2 in any 1 MHz at the boundary of the relevant adjacent
   area without negatively affecting the successful operations of the adjacent
   area licensee.
