Sec. 22.150  Standard pre-filing technical coordination procedure.

    For operations on certain channels in the Public Mobile Services, 
carriers

must attempt to coordinate the proposed use of spectrum with other 
spectrum users prior to filing an application for authority to operate a 
station. Rules requiring this procedure for specific channels and types 
of stations are contained in the subparts governing the individual 
Public Mobile Services.
    (a) Coordination comprises two steps--notification and response. 
Each step may be accomplished orally or in writing.
    (b) Notification must include relevant technical details of the 
proposal. At minimum, this should include the following:
    (1) Geographical coordinates of the antenna site(s).
    (2) Transmitting and receiving channels to be added or changed.
    (3) Transmitting power, emission type and polarization.
    (4) Transmitting antenna pattern and maximum gain.
    (5) Transmitting antenna height above ground level.
    (c) Applicants and licensees receiving notification must respond 
promptly, even if no channel usage conflicts are anticipated. If any 
notified party fails to respond within 30 days, the applicant may file 
the application without a response from that party.
    (d) The 30-day period begins on the date of receipt of the 
notification by the party being notified. If the notification is by 
mail, this date may be ascertained by:
    (1) The return receipt on certified mail,
    (2) The enclosure of a card to be dated and returned by the party 
being notified, or
    (3) A reasonable estimate of the time required for the mail to reach 
its destination. In this case, the date when the 30-day period will 
expire must be stated in the notification.
    (e) All channel usage conflicts discovered during the coordination 
process should be resolved prior to filing of the application. If the 
applicant is unable or unwilling to resolve a particular conflict, the 
application may be accepted for filing if it contains a statement 
describing the unresolved conflict and a brief explanation of the 
reasons why a resolution was not achieved.
    (f) If a number of changes in the technical parameters of a proposed 
facility become necessary during the course of the coordination process, 
an attempt should be made to minimize the number of separate 
notifications. If the changes are incorporated into a completely revised 
notice, the items that were changed from the previous notice should be 
identified.
    (g) In situations where subsequent changes are not numerous or 
complex, the party receiving the changed notification should make an 
effort to respond in less than 30 days. If the applicant believes a 
shorter response time is reasonable and appropriate, it should so 
indicate in the notice and suggest a response date.
    (h) If a subsequent change in the technical parameters of a proposed 
facility could not affect the facilities of one or more of the parties 
that received an initial notification, the applicant is not required to 
coordinate that change with these parties. However, these parties must 
be advised of the change and of the opinion that coordination is not 
required.
