1.10 to review the regulatory procedures and associated technical
criteria of Appendix **30B** without any action on the allotments, the
existing systems or the assignments in the List of Appendix **30B**

APPENDIX 30B (Rev. WRC-2000)

Provisions and associated Plan for the fixed-satellite service\
in the frequency bands 4 500-4 800 MHz, 6 725-7 025 MHz,\
10.70-10.95 GHz, 11.20-11.45 GHz and 12.75-13.25 GHz

Objective of the provisions and associated Plan

**NOC**

1.1

**MOD** EUR/10A10/1

1.2 The procedures prescribed in this Appendix shall in no way prevent
the implementa­tion of assignments in conformity with the national
allotments of the Plan.

**Reasons:** Consequential to elimination of Part B from the Plan.

**NOC**

ARTICLE 2

**NOC**

Definitions

**NOC**

2.1

**MOD** EUR/10A10/2

2.2 *Plan:* The Plan for the fixed-satellite service in the frequency
bands contained in this Appendix, consisting of national allotments.

**Reasons:** "Existing systems" are associated with FSS satellite
networks that had already been submitted to the ITU BR when the Plan was
developed. By now, the frequency assignments in these networks have
either been brought into use and become assignments in the List of
Appendix 30B or have been cancelled. Therefore there is no need for
keeping the concept of Part B of the Plan.

**MOD** EUR/10A10/3

2.3 *Allotment:* For the purpose of this Appendix, an allotment
comprises:

-- a nominal orbital position;

-- a bandwidth of 800 MHz (up-link and down-link) in the frequency bands
listed in Article 3 of this Appendix;

-- a service area for national coverage .

**Reasons:** The generalized parameters are not considered to be
necessary since examination of the compatibility of any proposed
assignment with allotments in the Plan or assignments in the List can be
conducted without calculating such parameters. As discussed and
justified in connection with Article 6 below, a non-sequential
processing of submissions is being proposed here and such an approach is
not compatible with retention of the PDA concept.

**MOD** EUR/10A10/4

2.4 *Existing systems:* Those satellite systems, in the frequency bands
covered by this Appendix, which are identified in
Resolution **\[EUR/10A10/109\]** **(WRC-07)**.

**SUP** EUR/10A10/5

2.5

**Reasons:** Subregional systems are now considered as "additional
systems" together with conversions of allotments into assignments and
modifications of assignments in the List under a single consolidated
procedure in Article 6 of Appendix 30B.

**MOD** EUR/10A10/6

2.6 *Additional* *system:* For the application of the provisions of this
Appendix, additional systems shall be understood to be a system for
which the assignments, notified by an administration, are not the result
of conversion of an allotment into assignments. An additional system may
also be submitted on behalf of a group of named administrations with one
designated administration to act as the notifying administration in
respect of the International Telecommunication Union.

**Reasons:** Definition of the new category of "additional systems"
covers both former "additional uses" and former "subregional systems".
The concepts of subregional systems and additional uses have been
introduced in the Appendix 30B Plan with different motivations. In
particular, subregional systems intended to allow neighbouring countries
to combine their allotments into a system with regional coverage. For
that reason, the possibility of suspending allotments was associated
with subregional systems. However, up to now the submissions for
subregional systems have seldom if ever included requests for suspension
or partial suspension of allotments and such submissions have been
implemented in a way that does not affect allotments in the Plan or
assignments in the List. Therefore, subregional systems have actually
been implemented as "additional uses" in the sense that they will
coexist with allotments and assignments as additional uses have. In view
of the above, it is proposed to eliminate the category of subregional
systems and to have a new and more simplified definition for "additional
system", capable of accommodating requirements currently being met by
the two existing categories.

**ADD** EUR/10A10/7

2.7. *List of assignments (hereafter called in short the "List"):* The
List associated with the Plan containing assignments resulting from the
successful application of the provisions of Article 6 of
Appendix **30B** or the application of Resolution **\[EUR/10A10/109\]
(WRC-07)**.

**Reasons:** Consequential to the revision of the provisions of Article
6 and the treatment of former Part B "existing systems" under Resolution
\[EUR/10A10/109\] (WRC-07).

**[NOC]{.underline}** EUR/10A10/8

ARTICLE 3

**[NOC]{.underline}** EUR/10A10/9

Frequency bands

**Reasons:** Article 3 does not need to be changed because the frequency
bands subject to Appendix 30B will remain the same.

**[NOC]{.underline}** EUR/10A10/10

ARTICLE 4

**[NOC]{.underline}** EUR/10A10/11

Execution of the provisions and associated Plan

**Reasons:** Article 4 should be retained as it is because it conveys
the general idea of operation with the characteristics of the Plan
(§ 4.1 of Article 4) and at the same time refers to the possible
exceptions contemplated in Appendix 30B itself or elsewhere in the Radio
Regulations.

**SUP** EUR/10A10/12

ARTICLE 5     (WRC-03)

The Plan and the associated List of assignments

**Reasons:** The predetermined arc (PDA) concept is not pertinent under
the example offered for consideration in this proposal. Additionally,
material relating to the List of assignments has been transferred to
Article 2 containing definitions.

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

^1^ If the payments are not received in accordance with the provisions
of Council Decision 482, as amended, on the implementation of cost
recovery for satellite network filings, the Bureau shall cancel the
publication specified in § 6.6 and the corresponding entries in the List
under § 6.22 or 6.24, as appropriate, after informing the administration
concerned. The Bureau shall inform all administrations of such action
and that the network specified in the publication in question no longer
has to be taken into consideration by the Bureau and other
administrations. The Bureau shall send a reminder to the notifying
administration not later than two months prior to the deadline for the
payment specified in the above‑mentioned Decision 482, unless the
payment has already been received (see also Resolution **87**

Section I -- Procedure for conversion of an allotment into an assignment

**Reasons:** Consequential to suppression of all sections of Article 6
except for Section II which is used as the basis for a new single
consolidated regulatory procedure.

**SUP** EUR/10A10/17

Section IA -- Procedure for conversion of an allotment into an
assignment that is not in conformity with Part A of the Plan or that
does not comply with Annex 3B

**Reasons:** Consequential to suppression of all sections of Article 6
except for Section II, which is used as the basis for a new single
consolidated regulatory procedure.

**SUP** EUR/10A10/18

Section IB -- Procedure for recording in the List of the existing
systems\
contained in Part B of the Plan

**Reasons:** This section is now irrelevant. Satellite systems in Part B
of the Plan have either been brought into use and have become
assignments in the List of Appendix 30B or have been cancelled and thus
Part B of the Plan is empty. "Existing systems" in § 2.4 of Article 2
are now covered by Resolution \[XXX\] (WRC-07).

**SUP** EUR/10A10/19

Section II -- Procedure for the introduction of a subregional system

**MOD** EUR/10A10/20

6.1 When an administration intends to convert an allotment into an
assignment or when an administration, or one acting on behalf of a group
of administrations^ADD 1B^, intends to introduce an additional system or
modify characteristics of assignment(s) in the List that has been
brought into use, it shall select, not earlier than eight years and not
later than two years before the planned date of bringing the assignment,
the additional system or the modified assignment(s) in the List into
use, send to the Bureau a notice containing the information specified in
Appendix **4**.      (WRC-03)

**Reasons:** The proposed Article 6 contains one single procedure for
submissions of assignments to be entered into the List in order to
simplify the regulatory text of Appendix 30B. The text clearly
identifies the three scenarios under which it applies: conversion of an
allotment into an assignment with or without modifications; additional
system; and modification of assignments in the List for systems that
were brought into use.

**ADD** EUR/10A10/21

\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_

^1B^ Whenever, under § 2.6, an administration acts on behalf of a group
of named administrations, all members of that group retain the right to
respond in respect of their own networks or systems.

**Reasons:** Gives administrations participating in an "additional
system" providing multinational services, equal rights with respect to
their own networks.

**ADD** EUR/10A10/22

6.2 If the information received by the Bureau under § 6.1 is found to be
incomplete, the Bureau shall immediately seek from the administration
concerned any clarification required and information not provided.

**Reasons:** To provide the Bureau with the ability to request
clarification and complementary information from the notifying
administration in case of an incomplete notice. This process serves the
same purpose in ensuring an efficient process of examination of notices
by the Bureau as that of § 11.27 of Article 11.

**SUP** EUR/10A10/23

6.39 to 6.42

**MOD** EUR/10A10/24

6.3 Upon receipt of a complete notice under § 6.1, the Bureau shall
examine each assignment in the notice:

*a)* with respect to its conformity with the Table of Frequency
Allocations and the other provisions of these Regulations, except those
provisions relating to conformity with the fixed-satellite service Plan,
*and*

*b)* with respect to its conformity with Annex 3 to this Appendix.

**Reasons:** In order to save time for the Bureau, it is proposed to
check at this time the compliance with the pfd limits. For clarity
reasons it is proposed to move these limits from Annex 4 to a new Annex
3.

**ADD** EUR/10A10/25

6.4 When the examination of any assignment in a notice received under
§ 6.1 with respect to § 6.3 leads to an unfavourable finding, the
relevant part of the notice shall be returned to the notifying
administration with an indication that subsequent resubmission will be
considered with a new date of receipt.

**Reasons:** Follows directly from the application of § 6.3. It is
proposed that the consequence of an unfavourable finding be similar to
that of Article 11.

**ADD** EUR/10A10/26

6.5 When the examination of each assignment in a notice received under
§ 6.1 with respect to § 6.3 leads to a favourable finding, the Bureau
shall use the method of Annex 4 to determine administrations whose:

-- allotments in the Plan; *or*

-- assignments which appear in the List; *or*

-- assignments for which the Bureau has previously received complete
information in accordance with § 6.1 of this Article,

are considered as being affected by any assignment in that notice.

**Reasons:** Follows directly from the application of MOD 6.3.
Simplified as a result of equal treatment of allotments, assignments in
the List and those systems for which the Bureau has previously received
complete information under § 6.1.

**ADD** EUR/10A10/27

6.6 The Bureau shall publish, in a Special Section of its International
Frequency Information Circular (BR IFIC), the complete information
received under § 6.1, together with the names of the administrations
identified under § 6.5 and the corresponding allotments in the Plan,
assignments in the List, assignments for which the Bureau has previously
received complete information in accordance with § 6.1 of this Article.

**Reasons:** The Bureau maintains transparency in the process of its
examinations by publishing the results of its examination for all ITU
members to view and to verify. This is a necessary provision of
information that would normally be expected by any affected
administration.

**ADD** EUR/10A10/28

6.7 The Bureau shall immediately send a telegram or fax to the
administration that has submitted the notice under § 6.1, drawing
attention to the requirement to seek and obtain the agreement of those
administrations identified as being affected in the Special Section of
the BR IFIC.

**ADD** EUR/10A10/29

6.8 The Bureau shall also send a telegram or fax to each administration
listed in the Special Section of the BR IFIC published under § 6.6,
drawing its attention to the information it contains.

**Reason:** Follows directly from ADD 6.6. This communication is a
necessary provision of information that would normally be expected by
any affected administration.

**ADD** EUR/10A10/30

6.9 Comments from affected administrations on the information published
under § 6.6 shall be sent either directly to the administration that has
submitted the notice under § 6.1 or through the Bureau within a period
of four (4) months following the date of the publication in the BR IFIC.
In any event, the Bureau shall be informed that comments have been made.

**Reasons:** The identified (affected) administration fulfils its
obligation to reply to the administration proposing the assignment
within a four (4) month regulatory time-frame while Bureau is kept
apprised of consultations in the event that their assistance is
requested by one of the parties.

**ADD** EUR/10A10/31

6.10 Thirty days prior to the expiry of the same four (4) month period,
the Bureau shall dispatch a reminder telegram or fax to each
administration listed in the Special Section published under § 6.6 which
has not made its comments under § 6.9, bringing the matter to its
attention.

**Reasons:** Courtesy to administrations and a safeguard in the event
that administrations were not aware that they were affected for whatever
reason.

**ADD** EUR/10A10/32

6.11 An administration which considers that it should have been
identified as affected in the publication referred to under § 6.6 above
shall, within four (4) months of the date of publication of the relevant
BR IFIC, and identifying the affected allotment, assignment or proposed
assignment, request the Bureau to include its name in the publication.
The Bureau shall study this information on the basis of Annex 4 and
shall inform both the affected administration and the administration
that submitted the notice of its conclusions. Should the Bureau agree to
the administration's request, it shall publish an addendum to the
publication under § 6.6.

**Reasons:** Provides administrations with recourse to demonstrate that
it should have been included in the Bureau's original list of affected
administrations and the opportunity to enter into a coordination
exercise.

**ADD** EUR/10A10/33

6.12 An administration that has not submitted its comments either
directly to the administration that has submitted the notice under § 6.1
or through the Bureau within a period of four (4) months following the
date of the BR IFIC referred to in § 6.6 shall be deemed to have agreed
to the proposed assignment.

**Reasons:** The onus is on the affected administration to act within
the 4 month regulatory time-frame to ensure its inclusion in the seeking
agreement process.

**ADD** EUR/10A10/34

6.13 After expiry of the deadline for comments in respect of any
assignment of the notice submitted under § 6.1, the Bureau shall,
according to its records, publish a Special Section indicating the list
of administrations identified under § 6.5 and published under § 6.6, or
published in an addendum to the publication under § 6.6 in accordance
with § 6.11, whose agreements are required for completion of the
Article 6 procedure.

**Reasons:** Finalizes the determination of the list of affected
administrations in the four (4) month regulatory time-frame.

**ADD** EUR/10A10/35

6.14 An administration may at any time during or after the
above-mentioned four month period inform the Bureau about their
objection to being included in the service area of each assignment in
the notice submitted under § 6.1, even if that assignment has been
entered in the List. The Bureau shall then inform the administration
which had submitted the notice and exclude the territory and test points
that are within the territory of the objecting administration from the
service area of the assignment(s) concerned. The Bureau shall update the
reference situation without reviewing the previous examination.

**ADD** EUR/10A10/36

6.15 If agreements have been reached with administrations identified in
accordance with § 6.13, the administration proposing the new or modified
assignment(s) may request the Bureau to have the assignment(s) entered
into the List, indicating the final characteristics of the assignment(s)
together with the names of the administrations with which agreement has
been reached. For this purpose, it shall send to the Bureau the
information specified in Appendix **4**. In submitting the notice, the
administration may request the Bureau to examine the notice under
§ 6.17, 6.19, 6.20 and 6.21 (entry into the List) and Article 8 of this
Appendix (notification).

**ADD** EUR/10A10/37

6.16 If the information received by the Bureau under § 6.15 is found to
be incomplete, the Bureau shall immediately seek from the administration
concerned any clarification required and information not provided.

**ADD** EUR/10A10/38

6.17 Upon receipt of a complete (Appendix **4**) notice under § 6.15,
the Bureau shall examine each assignment in the notice:

*a)* with respect to its conformity with respect to the Table of
Frequency Allocations and the other provisions of these Regulations,
except those provisions relating to conformity with the fixed-satellite
service Plan; *and*

*b)* with respect to its conformity with Annex 3 to this Appendix.

**ADD** EUR/10A10/39

6.18 When the examination with respect to § 6.17 of an assignment
received under § 6.15 leads to an unfavourable finding, the assignment
shall be returned to the notifying administration with an indication
that subsequent resubmission under § 6.15 will be considered with a new
date of receipt.

**ADD** EUR/10A10/40

6.19 When the examination with respect to § 6.17 of an assignment
received under § 6.15 leads to a favourable finding, the Bureau shall
use the method of Annex 4 to examine if the affected administrations and
the corresponding:

-- allotments in the Plan;

-- assignments which appear in the List at the date of receipt of the
examined notice submitted under § 6.1;

-- assignments for which the Bureau has previously received complete
information in accordance with § 6.1 of this Article at the date of
receipt of the examined notice submitted under § 6.1;

indicated in the Special Section published under § 6.13 and whose
agreement has not been provided under § 6.15 are still considered as
being affected by that assignment.

**ADD** EUR/10A10/41

6.20 The Bureau shall determine if the final characteristics of an
assignment received under § 6.15 cause more interference by checking if
they decrease the uplink single-entry *C*/*I* value or increase the
power flux-density on the service area of an allotment in the Plan or an
assignment in the List or an assignment for which the Bureau has
received complete information in accordance with this Article before the
date of receipt of the notice under § 6.15. If the final characteristics
cause more interference to an allotment in the Plan or assignment in the
List or assignment for which the Bureau has received complete
information in accordance with this Article, the Bureau shall use the
method of Annex 4 to determine whether that allotment or assignment is
considered as being affected by the proposed assignment without the
agreement of the identified administrations.

**ADD** EUR/10A10/42

6.21 The Bureau shall further examine each notice received under § 6.15
with a favourable finding under § 6.17 with respect to the requirement
for the notifying administration to seek the agreement of those
administrations whose territories are partially or wholly included in
the intended service area of the system.

**SUP** EUR/10A10/43

6.43*bis*

**ADD** EUR/10A10/44

6.22 In the event of a favourable finding under § 6.19, 6.20 and 6.21,
the Bureau shall enter the proposed assignment(s) in the List and
publish in a Special Section of its BR IFIC the characteristics of the
assignment(s) received under § 6.15, together with the names of
administrations with which the provisions of this Article have been
successfully applied. The administration may then notify the
assignment(s) in accordance with Article 8 of this Appendix.

**ADD** EUR/10A10/45

6.23 When the examination under § 6.19, 6.20 or 6.21 leads to an
unfavourable finding, the Bureau shall return the notice received under
§ 6.15 to the notifying administration together with the names of the
administrations with which necessary agreements under § 6.19, 6.20
or 6.21 have not been provided and with an indication that subsequent
resubmission under § 6.15 will be considered with a new date of receipt.

**Reasons:** If proposed characteristics generate more interference
towards assignments received before the date of receipt under § 6.15 and
the notifying administration has not obtained the agreement of the
affected assignments, this notice should be returned to the notifying
administration.

**ADD** EUR/10A10/46

6.24 After a notice is returned under § 6.23, should the notifying
administration resubmit the notice submitted under § 6.15 and insist
upon its reconsideration, the Bureau, on the condition of a favourable
finding with respect to § 6.21 and with respect to § 6.19 and 6.20 for
allotments in the Plan, shall enter the assignments provisionally in the
List with an indication of those administrations whose assignment(s)
were the basis of the unfavourable finding. The entry shall be changed
from provisional to definitive recording in the List only if the Bureau
is informed that the new assignment has been in use, together with the
assignment(s) which was the basis for the unfavourable finding, for at
least four (4) months without any complaint of harmful interference.

**ADD** EUR/10A10/47

6.25 When an assignment is entered provisionally in the List under the
provisions of § 6.24, that assignment shall not be taken into account in
updating the reference situation of that (those) assignment(s) which was
(were) the basis for the unfavourable finding.

**ADD** EUR/10A10/48

6.26 Should harmful interference be caused by an assignment entered in
the List under § 6.24 to any assignment in the List which was the basis
of the disagreement, the notifying administration of the assignment
entered in the List under § 6.24 shall, upon receipt of advice thereof,
immediately eliminate this harmful interference.

**SUP**

6.44 to 6.53

**MOD** EUR/10A10/49

6.27 When an assignment included in the List is no longer required, the
notifying administration shall immediately inform the Bureau.

**ADD** EUR/10A10/50

6.28 The date of bringing into use may be extended by the notifying
administration up to no more than eight years from the date of receipt
by the Bureau of the complete notice under § 6.1.

**ADD** EUR/10A10/51

6.29 Thirty days prior to the expiry of the date of bringing into use
under § 6.28, the Bureau shall dispatch a reminder telegram or fax to
the notifying administration, which has not brought its assignment into
use, bringing the matter to its attention.

**Reasons:** Ensure that the administration does not fail to provide
relevant information to the Bureau.

**ADD** EUR/10A10/52

6.30 When:

-- an assignment is no longer required; *or*

-- an assignment recorded in the List and brought into use has been
suspended for a period exceeding two years and ending after the expiry
date specified in § 6.28; *or*

-- an assignment recorded in the List has not been brought into use
within the eight-year period following the receipt by the Bureau of the
relevant complete information under § 6.1, with the exception of
national systems submitted by new Member States where § 6.32
and 7.3*bis* apply,

the Bureau shall:

*a)* publish in a Special Section of its BR IFIC the cancellation of the
related Special Sections and of the assignments recorded in the
Appendix **30B** List;

*b)* if the cancelled assignment is the result of a conversion of an
allotment without modification, reinstate the allotment in the
Appendix **30B** Plan;

*c)* if the cancelled assignment is the result of the conversion of an
allotment with modifications, reinstate the allotment with the same
orbital location and technical parameters of the cancelled assignment
except for its service area that shall be the national territory of the
administration whose allotment is being reinstated; *and*

*d)* update the reference situation for the allotments of the Plan and
the assignments of the List.

**ADD** EUR/10A10/53

6.31 When a proposed new or modified frequency assignment has not
fulfilled all the requirements for entering the List, in accordance with
§ 6.22 or 6.24, by the expiry date specified in § 6.28 the Bureau shall
publish in a Special Section of the BR IFIC the cancellation of the
related Special Sections.

**ADD** EUR/10A10/54

6.32 The procedure of this Article may be applied by the administration
of a new ITU Member State in order to include new assignments in the
List. Upon completion of the procedure, the administration may request
the Bureau to convert the assignments in the List to an allotment with a
service area that shall be the national territory of the administration
for inclusion in the Plan and the Bureau shall then delete the
associated assignments recorded in the List.

**Reasons:** The Plan, being a Plan of national allotments, needs to be
updated to account for and reflect geopolitical changes that take place
over time. New Member States should be afforded entry(ies) in the Plan
according to the provisions of this Appendix. It is therefore reasonable
that following the successful completion of these procedures, the
results of the successful application of

the procedures of this Appendix are captured and recorded in the Plan.
This approach would allow for the equitable treatment of new and
existing ITU Member States.

**NOC**

Procedure for the addition of a new allotment to the Plan\
for a new Member State of the Union

**MOD** EUR/10A10/55

7.1 The administration of a country which has joined the Union as a new
Member State shall obtain a national allotment in the Plan by the
following procedure.

**MOD** EUR/10A10/56

7.2 The administration shall submit its request for an allotment to the
Bureau, with the following information:

*a)* the geographical coordinates of not more than 20 test points for
determining the minimal ellipse to cover its national territory;

*b)* the height above sea level of each of its test points;

*c)* any special requirement, other than a fixed orbital position, which
is to be taken into account to the extent practicable.

**MOD** EUR/10A10/57

7.3 Upon receipt of the complete information (mentioned in § 7.2 above),
the Bureau shall identify and suggest to the requesting administration
appropriate orbital positions, one of which should be selected by the
requesting administration. If the examination with respect to § 8.8 of
Article 8 and compatibility with allotments, assignments of other
administrations and notices received under § 6.1 or 6.15 before the date
of receipt of the request under § 7.2, leads to a favourable finding,
the Bureau shall enter the national allotment of the new Member State of
the Union in the Plan and publish the characteristics of the allotment
concerned and the result of its examination in a Special Section of the
BR IFIC with the updated reference situation.

9.1 The Plan is limited to national systems providing a domestic

of Article 6, convert their allotments or propose additional systems to
provide multinational services.

**Reasons:** Changes are consequential of the consolidated regulatory
procedures introduced in Article 6.

**SUP** EUR/10A10/71

9.2

**Reasons:** Existing systems are associated with FSS satellite networks
that had already been submitted to BR when the Plan was developed. By
now, the frequency assignments in these networks have either been
brought into use and become assignments in the List or have been
cancelled. Paragraph 9.2 strictly applied would require all these
frequency assignments to cease operation (or operate under No. 4.4 of
the Radio Regulations) after 16 March 2010. Operation under No. 4.4 is
not a realistic option, at least as Appendix 30B frequencies are more
widely used. Moreover, requiring that operational satellite networks
with large number of users cease abruptly their operation is
unreasonable. By suppressing § 9.2, frequency assignments of existing
systems that have been brought into use just remain in the List
similarly to the way in which frequency assignments associated with
subregional systems are currently treated. Resolution \[EUR/10A10/109\]

Parameters used in characterizing the fixed-satellite service Plan

**MOD** EUR/10A10/97

Section A -- Technical data used in establishing the Allotment Plan\
and the associated provisions

# 1 Basic technical characteristics

The allotments in the Plan are based on a reference satellite network
with the following assumptions:

## 1.1 Type of modulation

The Plan is independent of modulation characteristics and accessing
techniques.

## 1.2 Carrier-to-noise ratio

The carrier-to-noise ratio (*C */* N*) is as follows:

*a)* the uplink *C*/*N* ratio under rain fading conditions exceeds
21 dB;

*b)* the downlink *C*/*N* ratio under rain fading conditions exceeds
15 dB;

*c)* the total link *C*/*N* under rain fading conditions exceeds 14 dB;

*d)* for the 6/4 GHz bands, the above *C */* N*s are exceeded for 99.95%
of the year (NOTE -- The rain attenuation margin is limited to a maximum
of 8 dB);

*e)* for the 13/10-11 GHz bands, the above *C */* N*s are exceeded for
99.9% of the year

(NOTE -- The rain attenuation margin is limited to a maximum of 8 dB);

*f)* the gaseous atmospheric attenuation and rain attenuation models
used are those described in Recommendations ITU‑R P.676-6 and
ITU‑R P.618-8, respectively.

## 1.3 Earth station antenna elevation angle

The minimum elevation angle for each test point defining the service
area is based on the following:

10° for climatic zones A to G;

20° for climatic zones H to L;

30° for climatic zones M and N;

40° for climatic zones P and Q.

Administrations may select lower elevation angles for their service
areas. For countries at high latitudes or with dispersed territories, in
the absence of such a request, if the above values for minimum elevation
angle are unobtainable, then the highest elevation angle leading to a
non-zero service arc applies. In mountainous areas, the elevation angles
are specified by the administrations concerned.

## 1.4 Interference criteria

The Plan has been prepared with a view to assuring for each allotment an
aggregate carrier-to-interference ratio under free-space conditions of
21 dB or higher.

## 1.5 Polarization

Polarization isolation between satellite networks was not used in the
development of the Allotment Plan.

## 1.6 Earth station characteristics

1.6.1 The diameters of the earth station antennas are:

4.6 m for the 6/4 GHz band;

2.4 m for the 13/10-11 GHz band.

1.6.2 The earth station receiving system noise temperature referred to
the output of the receiving antenna is:

95 K for the 4 GHz band;

125 K for the 10-11 GHz band.

1.6.3 The earth station antenna efficiency is 70%.

1.6.4 The earth station antenna reference pattern applicable to all
allotments is shown in Table 1 below.

-- the calculated Earth-to-space single-entry carrier-to-interference
ratio at any test point within the service area of the interfered
satellite network is more than or equal to *C*/*N~ref_up~* + 12.2 dB,

aggregate carrier-to-interference ratio averaged over the necessary\
bandwidth of the modulated carrier

# 1 Earth-to-space single-entry

This section describes the method for calculating the Earth-to-space
single-entry interference potential.

The method is based on the single-entry carrier-to-interference ratio
(*C */* I *) which a given allotment or assignment made in accordance
with the provisions of Appendix **30B** might experience due to emission
from the proposed modification for which the minimum orbital separation
with a given allotment or assignment under worst-case station-keeping
conditions is less than 10° in the 6/4 GHz band and 9° in the
13/10-11 GHz band.

The single-entry *C */* I* due to a single interfering satellite network
is given by:

(*C */* I *)*u* =
$\left( \frac{p_{1}g_{1}g_{2}(\phi)1_{su^{'}}}{p_{1^{\prime}}g_{1^{\prime}}(\theta)g_{2}(\rho)1_{\text{su}}} \right)$

RESOLUTION \[EUR/10A10/109\] (WRC-07)

Satellite systems in Part B of Appendix 30B (WARC-Orb-88)

The World Radiocommunication Conference (Geneva, 2007),

considering

*a)* that WARC‑Orb‑88 adopted a Plan for the fixed-satellite service in
the frequency bands 4 500-4 800 MHz, 6 725-7 025 MHz, 10.70-10.95 GHz,
11.20-11.45 GHz and 12.75-13.25 GHz as contained in Appendix **30B**;

*b)* that, when the Plan was adopted, some satellite systems in the same
frequency bands were under coordination or had been recorded in the
Master International Frequency Register (MIFR) or had information
relating to advance publication that was received by the
Radiocommunication Bureau before 8 August 1985, and which in all cases
were listed in Part B of the Plan at WARC‑Orb‑88;

*c)* that in the original provisions of Appendix **30B** (WARC‑Orb‑88),
the satellite systems referred to in *considering b)* above were
designated as "existing systems";

*d)* that satellite systems identified in *considering b)* have either
been included in the List of Appendix **30B** or cancelled, and thus
Part B of the Plan is empty;

*e)* that therefore WRC‑07 suppressed Part B of the Plan in
Appendix **30B**,

recognizing

*a)* that Article 9.2 of Appendix **30B** (WARC‑Orb‑88) indicates that
"The existing systems listed in Part B of the Plan may continue in
operation for a maximum period of 20 years from the date of entry into
force of this Appendix", and consequently the period of operation of
satellite systems in Part B of the Plan expires after 16 March 2010;

*b)* that some administrations expressed their wish to continue
operation of these systems after the deadline mentioned in
*recognizing a)*;

*c)* that satellite systems referred to in *considering b)* are
compatible with satellite networks in Appendix **30B**,

resolves

1 that the period of validity of assignments to "existing system(s)" as
referred to in *considering c)* shall be extended until 42 months from
the closing of the Conference (WRC‑07) at the request of the notifying
administration;

2 that administrations intending to further operate assignments to
"existing system(s)" as referred to in *considering c)* shall so inform
the Radiocommunication Bureau before 16 March 2010, indicating which
assignments are concerned;

3 that, after the notifying administration has acted in accordance with
*resolves *2, assignments to "existing system(s)" as referred to in
*considering c)* may continue to be operated in accordance with the
period of validity including the extension provided in *resolves* 1 if
appropriate;

4 that an administration wishing to further extend the notified period
of validity of assignments to "existing system(s)" as referred to in
*considering c)* shall inform the Bureau accordingly more than three
years before the expiry of the period in question and if that assignment
remains unchanged, the Bureau shall amend, as requested, the period of
validity and publish that information in a special section of the
Bureau's International Frequency Information Circular (BR IFIC),

instructs the Radiocommunication Bureau

1 to cancel from the Master Register and the List assignments to
"existing system(s)" as referred to in *considering c)* upon expiry of
their period of validity or on 16 March 2010 if the notifying
administration failed to communicate to the Radiocommunication Bureau
the confirmation in accordance with *resolves* 2;

2 to take the appropriate actions in accordance with *resolves *1 and 4.

\_\_\_\_\_\_\_\_\_\_\_\_

[^1]: ^1D^ These limits shall not apply to assignments recorded in the
    List before 16 November 2007 or to any proposed new allotment or
    assignment for which the Bureau has received information in
    accordance with Article 6 before 16 November 2007.

[^2]: ^1E^ These limits shall not apply to any assignment entered in the
    List before WRC‑07.
