--InterferenceInterference--free operationfree operation

--international recognitioninternational recognition

by recording frequency assignments and, as appropriate, orbital positions used or intended to

be used in the

Master International Frequency Register Master International Frequency Register (MIFR)(MIFR)

COORDINATION means

Obligatory NEGOTIATION between Administrations

to

arrive at ” interference-free” operation

by

following the processes and Procedures described in Radio Regulations

Radio Regulations-a binding international treaty(No. 31 of the ITU Constitution)

We shall focus upon the: Coordination Approach

dhh

Coordination is central to the three stage process :

Advance Publication of Information

(API)

Coordination

Notification & Recording in the Master International

Frequency Register(MIFR)

Submission of advance informationthat is published by the BR

Exam. by BR to establish Findings, coordination Requirements and to publish . Coordination is then carried out by the responsible administration.

Examination of the Notification, checking of Coordordination Agreements & Recording in MIFR

Let us now focus on the process of coordination to establish Findings

and coordination Requirements

Coordination Examination comprises of two parts:

No. 9.35 (11.31)

Compliance with Table of Frequency Allocation

No. 9.36:

Identify any administration with which coordination may need to be effected

No. 9.35 (11.31)Compliance with Table of Frequency Allocation

refers to:

Conformity with

the `Table of Frequency Allocations’

(Article 5)Successful application

of No.9.21(when reqd.)
