§ 5.85 Frequencies and policy governing frequency assignment.
(a)(1) Stations operating in the Experimental Radio Service may be
authorized to use any Federal or non-Federal frequency designated in the
Table of Frequency Allocations set forth in part 2 of this chapter, provided
that the need for the frequency requested is fully justified by the
applicant. Stations authorized under Subparts E and F are subject to
additional restrictions.
(2) Applications to use any frequency or frequency band exclusively
allocated to the passive services (including the radio astronomy service)
must include an explicit justification of why nearby bands that have
non-passive allocations are not adequate for the experiment. Such
applications must also state that the applicant acknowledges that long term
or multiple location use of passive bands is not possible and that the
applicant intends to transition any long-term use to a band with appropriate
allocations.
(b) Frequency or frequency bands are assigned to stations in the
Experimental Radio Service on a shared basis and are not assigned for the
exclusive use of any one licensee. Frequency assignments may be restricted
to specified geographical areas.
(c) Broadcast experimental radio stations. (1) The applicant shall select
frequencies best suited to the purpose of the experimentation and on which
there appears to be the least likelihood of interference to established
stations.
(2) Except as indicated only frequencies allocated to broadcasting service
are assigned. If an experiment cannot be feasibly conducted on frequencies
allocated to a broadcasting service, an experimental station may be
authorized to operate on other frequencies upon a satisfactory showing of
the need therefore and a showing that the proposed operation can be
conducted without causing harmful interference to established services.
(d) Use of Public Safety Frequencies. (1) Conventional experimental
licenses. Applicants in the Experimental Radio Service shall avoid use of
public safety frequencies identified in part 90 of this chapter except when
a compelling showing is made that use of such frequencies is in the public
interest. If an experimental license to use public safety radio frequencies
is granted, the authorization will include a condition requiring the
experimental licensee to coordinate the operation with the appropriate
frequency coordinator or all of the public safety licensees using the
frequencies in question in the experimenter's proposed area of operation.
(2) Program experimental licenses. A program licensee shall plan a program
of experimentation that avoids use of public safety frequencies, and may
only operate on such frequencies when it can make a compelling showing that
use of such frequencies is in the public interest. A licensee planning to
operate on public safety frequencies must incorporate its public interest
showing into the narrative statement it prepares under § 5.309(a)(1), and
must coordinate, prior to operating, with the appropriate frequency
coordinator or all of the public safety licensees that operate on the
frequencies in question in the program experimental licensee's proposed area
of operation
(e) The Commission may, at its discretion, condition any experimental
license or STA on the requirement that before commencing operation, the new
licensee coordinate its proposed facility with other licensees that may
receive interference as a result of the new licensee's operations.
(f) Protection of FCC monitoring stations. (1) Applicants may need to
protect FCC monitoring stations from interference and their station
authorization may be conditioned accordingly. Geographical coordinates of
such stations are listed in § 0.121(b) of this chapter.
(2) In the event that calculated value of expected field strength exceeds a
direct wave fundamental field strength of greater than 10 mV/m in the
authorized bandwidth of service (−65.8 dBW/m2 power flux density assuming a
free space characteristic impedance of 120π ohms) at the reference
coordinates, or if there is any question whether field strength levels might
exceed the threshold value, the applicant should call the FCC, telephone
1-888-225-5322 (1-888-CALL FCC).
(3) Coordination is suggested particularly for those applicants who have no
reliable data that indicates whether the field strength or power flux
density figure indicated in paragraph (f)(2) of this section would be
exceeded by their proposed radio facilities (except mobile stations). The
following is a suggested guide for determining whether coordination is
needed:
(i) All stations within 2.4 kilometers (1.5 statute miles);
(ii) Stations within 4.8 kilometers (3 statute miles) with 50 watts or more
average ERP in the primary plane of polarization in the azimuthal direction
of the Monitoring Station;
(iii) Stations within 16 kilometers (10 statute miles) with 1 kW or more
average ERP in the primary plane of polarization in the azimuthal direction
of the Monitoring Station;
(iv) Stations within 80 kilometers (50 statute miles) with 25 kW or more
average ERP in the primary plane of polarization in the azimuthal direction
of the Monitoring Station.
(4) Advance coordination for stations operating above 1000 MHz is
recommended only where the proposed station is in the vicinity of a
monitoring station designated as a satellite monitoring facility in
§ 0.121(b) of this chapter and also meets the criteria outlined in paragraphs
(f)(2) and (3) of this section.
