arrive at ” interference-free” operation

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

Coordination is central to the three stage process :

Advance Publication of Information

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

Advance Publication of Information

Notification & Recording in the Master International

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.)

Conformity with

other procedures i.e. Rules of Procedure(RoP)

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