Notification
Notification
Any 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.

3
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).

4
Above 30 MHz - Bilateral Agreement

• Pro Active Process
• Co-ordination versus notification
• Sharing arrangements by band
• Some bands first-come, first-served
• Others block and zone
• Electronic exchange of proposals

5
Bilateral Co-ordination - Management Objectives

• Better agreements
• Faster access to spectrum
• Strategies
• Reduce case-by-case co-ordination

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.

a)COORDINATION
THE NEED FOR COORDINATION
WITH WHOM ? ADMINISTRATIONS OF NEIGHBOURING
COUNTRIES WHOSE TERRITORIES LIE WHOLLY OR PARTLY
WITHIN THE COORDINATION AREA OF THE PLANNED
STATION
WHEN ? BEFORE NOTIFYING TO THE
RADIOCOMMUNICATION BUREAU OR BRINGING INTO USE
ANY FREQUENCY ASSIGNMENT TO AN STATION

• 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.

29
b)COORDINATION
COORDINATION
Coordination of a new network is required when
it operates 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

• 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

• RR 11 Section II (RR 11.27 to RR 11.49)
• In order of their date of receipt
• Regulatory
• Technical
• Compatibility with Regional/Worlwide Agreements
  (ST61, RJ81, GE89, etc)

32
b) Examination of notices
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.

MIFR Error 1
Incorrect data in SRS database The detailed
examination of the SRS database and the
corresponding IFICs 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.) - bandwid
th 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.

Conclusions

• The usefulness of the Master Register depends on
  the notifications made by each administration

Analysis of the ITU-BR SRS database show that a
large number of networks, already operational,
have not been sent to BR for notification -INTEL
SAT5 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 request
Coordination 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.
61
a)Terrestrial stations

• - 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.

terrestrial stations - calculate (or use
notified) E.I.R.P. of the transmitting terrestri
al stations - determine the antenna gain of the
terrestrial stations in the earth station
direction - auxiliary contours for the earth
stations

The method of App7
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.)

Decision
COORDINATION PROCESS (7)
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

Narrow Bandwidth Emissions
The emissions with BW less than reference BW
generate error if a reference BW is not used in
calculations.
The narrow bandwidth emissions should be
considered in all reference bands (without empty
slots) if operators doesn supply emissions

b) Broadcasting Agreements
2. b) Relevant Cases involving Broadcasting
Agreements

• Regional LF/MF Broadcasting Agreement, Regions 1
  and 3, Geneva, 1975

• Regional Agreement relating to the Use of the
  Band 87.5 - 108 MHz for FM Sound Broadcasting,
  Region 1 and part of Region 3 - Afghanistan and
  the Islamic Republic of Iran, Geneva, 1984

Broadcasting in this band is faced with the
problem of compatibility with aeronautical
radionavigation services (ILS/VOR) operating in
the immediately adjacent band (108 - 117.95).

• Regional Agreement relating to the Planning of
  VHF/UHF Television Broadcasting in the African
  Broadcasting Area and Neighbouring Countries,
  Geneva, 1989
