§ 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;
(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
(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/m2 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/m2 in any 1 MHz at the boundary of the
relevant adjacent area without negatively affecting the successful
operations of the adjacent area licensee.
