Notification of frequency Assignment for recording in the Master Register Notification

NotificationAny frequency assignment to a transmitting station and to its associated receiving stations except for those mentioned in Nos. 11.13 and 11.14 shall be notified to the ITU Radio Bureau.Why to notify?

Which assignments should be notified?How to notify an assignment?When to notify ?Where to notify ?

• International registration provides:• international recognition of services and frequency plans;• It is usual to notify international frequency use after successful

negotiations between countries;• There are some circumstances detailed in the ITU Radio

Regulations when an administration is obliged to notify its use of the spectrum.



Considering Other Users

• The procedures for allocating frequencies must also consider the impact of other countries’ assignments as published in:– ITU Frequency Plans; – the ITU International Frequencies List (IFL); and– Information circulars published by the

Radiocommunication Bureau (IFIC).

International Frequency Coordination• Since the electromagnetic spectrum is a global shared asset,

otherwise autonomous administrations must agree to cooperate for the benefit of all.

• The ITU Radio Regulations are the basis for this agreement.

• The agreed procedures aim to avoid mutual interference by exchanging and analysing frequency allocation data.

Coordination Procedures:• There are three main parts to formal coordination procedures:

– how the process will be administered;– how information is to be recorded, and exchanged;– how technical information is to be gathered, analysed and

reported.• Coordination procedures will also specify restrictions on uses of

assigned frequencies.

THE NEED FOR COORDINATION THE NEED FOR COORDINATION

WHEN ?

BEFORE NOTIFYING TO THE RADIOCOMMUNICATION BUREAU OR

BRINGING INTO USE ANY FREQUENCY ASSIGNMENT TO AN STATION

a)COORDINATION

• Coordination is a regulatory obligation:- for the administration wishing to assign a frequency to a station;- for any other administration whose services might be affected;

• The agreement resulting from the coordination involves certain legal rights and obligations

• Coordination must be effected in accordance with RR procedures and on the basis of the criteria established by the RR or agreement

between administrations.



Coordination of a new network is required when itoperates in the same frequency bands as networks that:

-are in conformity with the provisions of the RR;- are already recorded in the Master Register; - or have already been coordinated - or are undergoing coordination in accordance with Section

II of Art.11;-if the threshold value of AP29 is exceeded- Coordination is not required: RR1066-RR1071

COORDINATION

• Information required by Appendix S4 (Circular Letter CR/65) sent to all Administrations with which coordination is required

• Copy sent to the Bureau• Can commence minimum 6 months after AP-I• Must be carried out before notification or bringing into use

a)Examination of Notices The Bureau examines Appendix 3 information for completeness and

conformity with:- Table of Frequency Allocations- Other provisions of the RR (except for coordination provisions and probability of harmful interference)

The Bureau identifies any other Administration whose space services might be affected

The Bureau publishes the coordination request in a Special Section of its Weekly Circular including the results of its examination

Notification of frequency Assignment for recording in the Master Registerb) Examination

of notices

If the notice contains all the necessary information, it is published in Part I of the Weekly Circular at the latest two months after its receipt (11.28/RR 1235). Subsequent processing of a notice varies according to the frequency band and service concerned. Article 11 (12) specifies the various cases.It is to be noted that the former systematic examination of the probability of harmful interference, in the bands below 28 MHz, no longer appears in the Regulations adopted by WRC-95 and WAC-97, and was even abandoned as from 18 November 1995, pursuant to the decisions of WRC-95.

Incorrect data in SRS database

The detailed examination of the SRS database and the corresponding IFIC’s shows more than 20000 cases (assignments) containing incorrect data:- maximum power density in 1 Hz (Pd) is less than average power in Hz of the emission (Pav) with up to 76 dB (Pav_Pd) (Table.1.);

Pav = Pa - BWdb- maximum power density (Pd) is higher than total power (Pa) (Table.2.);- bandwidth of the emission (BWemiss) is wider than the bandwidth of the channel (bdwdth) (Table.3), etc. Examination with such incorrect data results in incorrect findings of the BR. The satellite networks would not work using such vallues of the parameters, but the coordinations on paper are completed successfuly.

Rights

Participation

Analysis of the ITU-BR SRS database show that a large number of networks, already operational, have not been sent to BR for notification:-“INTELSAT5 XXX” – 57 notices are under coordination;-“INTELSAT7 XXX” – 106 notices are under coordination;-“INTELSAT8 XXX” – 126 notices are under coordination;-“INTELSAT9 XXX” – all notices are under coordination.

Coordination requestCoordination information shall be sent (Nos. 9.29, 9.31) by the requesting administration (Administration A) to all administrations (Administration B) identified using coordination area.

The coordination is expected to be concluded within a period of four months but may take longer in many cases due to the requirement for detailed interference calculations between the earth station and existing or planned terrestrial stations. The requesting administration may, therefore, sometimes receive a copy of the diagram indicating the location of existing terrestrial radiocommunication stations and/or the ones planned to be brought into use in the next three years within the coordination area of the earth station, together with relevant basic characteristics and with such suggestions to achieve a satisfactory solution to the problem.



- Coordination of terrestrial stations within the coordination area of an earth station

- Coordination with respect to earth station assignments

which are :• in conformity with RR1503 and• either coordinated under RR1107 or for which

coordination has been initiated (not for Res 46) or• recorded in the MIFR with a favourable finding.Administration requesting coordination should

send to the Administration concerned :- Diagram with location of the terrestrial stations ;- characteristics of frequency assignments ;- planned date of bringing into use.

Affected Administrations

• Affected Administration examines coordination request and then notifies requesting Administration within 4 months of date of publication of either:- its agreement to the proposal, or- its disagreement, along with pertinent details upon which disagreement is based .

• Administration initiating coordination communicates to the Bureau, after 4 months, the agreement obtained and the progress made with other administrations.

Technical examination – Examine the coordination data; A decision is to be taken within 4 monthsRequest BR’s assistanceRR1142-RR1144



Examination of the coordination request• Collect technical data for terrestrial stations to be

taken into consideration :- recorded in MIFR;- in operation in conformity with the RR but not yet notified to the BR;

Examination

Technical examination- draw on a map with an appropriate scale the location

of the terrestrial stations - calculate (or use notified) E.I.R.P. of the transmitting

terrestrial stations- determine the antenna gain of the terrestrial stations

in the earth station direction- auxiliary contours for the earth stations



The method of App7 is based on most

unfavourable assumptions

- more detailed examination (acceptable level of

interference, percentage of time, terrain profile,

type of modulation etc.)

The method of App7



4 - month period for decision

- agreement (indicating the coordinated frequency

assignments)

- agreement (with a list of appropriate terrestrial stations)

- disagreement with a copy of diagram with locations of

the terrestrial stations within the coordination area

together with all relevant characteristics and suggestions

to solve the problem

The narrow bandwidth emissions should be considered in all reference bands (without empty slots) if operators does’n supply emissions carrier plan of the satellite transponders

Narrow Bandwidth Emissions

The emissions with BW less than reference BW generate error if a reference BW is not used in calculations.
