PRELIMINARY POSITION
OF THE RCC CAs ON THE AGENDA ITEMS
OF THE WORLD
RADIOCOMMUNICATION CONFERENCE
2012
1.1
•
To consider and take appropriate action on requests from administrations to delete
their country footnotes or to have their country name deleted from footnotes, if no
longer required,taking into account Resolution 26 (Rev.WRC-07).
• RCC CAs support the ITU-R activities towards the worldwide
harmonization of the radio frequency spectrum usage by
reducing the number of national footnotes to Article 5 of the
Radio Regulations.
ACP WG-F

1.2
•
Taking into account the ITU-R studies carried out in accordance with Resolution 951 (Rev.WRC07), to take appropriate action with a view to enhancing the international regulatory
framework.
•
•
•
•
Convergence of terrestrial services
RCC CAs are of the view that current provisions of the Radio Regulations do not limit the use of
different applications in terrestrial services (fixed and mobile).
(see also Method A1 of the draft CPM Report)
•
•
Convergence of satellite services
In relation to convergence of satellite services, RCC CAs believe that modifications of the Radio
Regulations provisions are not reasonable. The current procedures of the Radio Regulations
provide the necessary flexibility to the administrations in terms of choice of satellite service
applications in the frame of existing frequency bands allocations.
•
•
General principles of frequency bands allocation
1. RCC CAs support that studies on improvement of international regulatory framework and
principles of allocation of the frequency bands for radio services should be finalized at WRC-12.
2. RCC CAs believe that current regulatory framework provide sufficient flexibility and does not
prevent the implementation of new technologies.

1.3
•
•
•
To consider spectrum requirements and possible regulatory actions, including allocations, in
order to support the safe operation of unmanned aircraft systems (UAS), based on the results of
ITU-R studies, in accordance with Resolution 421 (WRC-07).
•
1
•
•
•
. RCC CAs are of the view that to ensure the safe flight operation of UAS in nonsegregated airspace the existing and/or new allocations to AMS(R)S (for satellite
component of UAS), as well as AM(R)S and ARNS (for terrestrial component of UAS)
should be used provided that compatibility with incumbent services is ensured.
2. RCC CAs are of opinion that the development of appropriate international ICAO
standards for systems operating in AMS(R)S, AM(R)S and ARNS shall be mandatory
since these services are intended for provision of safety and regularity of flights
including international routes of civil aviation.
3. RCC CAs do not support consideration of the bands 960-1164 MHz, 1525-1559 MHz,
1610- 1660.5 MHz, 5000-5030 MHz and 15.4-15.7 GHz as candidate ones for the safe
flight operation of UAS.
4. RCC CAs do not support any proposals to modify the Radio regulations with respect
to frequency bands for which studies under WRC-12 AI 1.3 have not yet been
completed.
ACP WG-F

1.4
•
To consider, based on the results of ITU-R studies, any further regulatory measures to facilitate
introduction of new aeronautical mobile (R) service (AM(R)S) systems in the bands 112-117.975
MHz, 960-1164 MHz and 5000-5030 MHz in accordance with Resolutions 413 (Rev.WRC-07), 417
(WRC-07) and 420 (WRC-07).
•
•
Resolution 413 (Rev. WRC-07)
RCC CAs do no object to the usage of the frequency band 112 – 117.975 MHz by
AM(R)S systems since the conducted studies showed the possibility of its
compatibility with the analogue broadcasting systems operating in the bands
below 108 MHz. The AM(R)S usage should be limited by the systems which should
operate in accordance with the acknowledged international aviation standards.
RCC CAs support the appropriate modifications of Resolution 413.
(see also Method A of the draft CPM Report)
Resolution 417 (WRC-07)
•
•
•
•
1. RCC CAs are of the view that protection of ARNS stations from systems of
AM(R)S in the frequency band 960-1164 MHz, as well as compatibility of AM(R)S
systems in the band 960-1164 МHz with RNSS stations operating in the adjacent
band 1164-1215 МHz shall be ensured.
ACP WG-F

1.4
• 2. RCC CAs support the modification of Resolution 417 (Rev.WRC12) with respect of the conditions of protection of ARNS operating
in the frequency band 960 – 1164 MHz and the stations of RNSS
operating in the adjacent frequency bands 1164 – 1215 MHz from
the interference caused by the stations of AM(R)S operating in the
frequency band 960 – 1164 MHz.
• (see also Method B1 of the draft CPM Report).
• Resolution 420 (WRC-07)
• RCC CAs do not object the allocation of the frequency band 5 000 –
5 010 MHz to AM(R)S provided that the compatibility with the
existing radio services in this and adjacent frequency bands under
adopted restrictions is ensured.
• (see also Method C2 of the draft CPM Report)

1.5
•
•
•
To consider worldwide/regional harmonization of spectrum for electronic news gathering
(ENG), taking into account the results of ITU-R studies, in accordance with Resolution 954
(WRC-07).
•
•
RCC CAs consider that:
- spectrum harmonization for ENG systems should be conducted in the
frequency bands already allocated for the services on the worldwide or
regional basis and appropriate for the use of ENG;
- when considering the spectrum harmonization for ENG the protection of
other applications used by administrations in the considered frequency bands
should be ensured;
- when considering the spectrum harmonization for ENG it is necessary to take
into account the existence of effective encoding and audiovisual data
compression methods. At the same time it is necessary to take into account
both the existing technologies of increasing the efficiency of channel resource
usage and the advanced audiovisual data transmitting technologies taking into
account their implementation and maintenance practice.

1.7
•
To consider the results of ITU-R studies in accordance with Resolution 222 (Rev.WRC-07) in order to
ensure long-term spectrum availability and access to spectrum necessary to meet requirements for the
aeronautical mobile-satellite (R) service, and to take appropriate action on this subject, while retaining
unchanged the generic allocation to the mobile-satellite service in the bands 1 525-1 559 MHz and 1
626.5-1 660.5 MHz.
•
1. Ensuring guaranteed long-term access of AMS(R)S to the bands 1525 – 1559/1626.5 – 1660.5
MHz should not result in the change of the existing general allocation of these frequency bands to
the MSS or impose constraints on existing MSS systems operated in accordance with the RR
provisions.
2. Existing regulatory provisions defining the AMS(R)S status (RR No. 5.357A) give priority when
satisfying existing AMS(R)S spectrum requirements for communications with priority 1 to 6 as per
Article 44 in the bands 1545 – 1555 / 1646.5 – 1656.5 MHz. Therefore current regulatory
provisions defining the existing usage of the bands 1545 – 1555 / 1646.5 – 1656.5 MHz for
AMS(R)S, in particular No. 5.357A, should remain unchanged (see also Method C of the draft CPM
Report).
3. To satisfy future spectrum requirements for AMS(R)S it is expedient to consider other existing
AMS(R)S allocations (for example in the band 5 GHz) or new AMS(R)S allocations exclusively for
transmitting messages with priority 1 to 6 as per Article 44 since realization of future AMS(R)S
spectrum requirements in the bands 1545 – 1555 / 1646.5 – 1656.5 MHz (according to RR No.
5.357A) will inevitably impose undue constrains on the existing MSS systems (taking into account
that bands 1525 – 1559 / 1626.5 – 1660.5 MHz are extremely in demand and limited).

•
To revise frequencies and channelling arrangements of Appendix 17 to the Radio Regulations, in
accordance with Resolution 351 (Rev.WRC-07), in order to implement new digital technologies for the
maritime mobile service.
•
RCC CAs support revision of the Appendix 17 of the Radio Regulations according to
Resolution 351 (Rev.WRC-07) if the following requirements are satisfied:
•
- the implementation of changes of Appendix 17 requires a transition period (till
01.01.2015);
- conditions and channelling arrangements for telephony in Appendix 17 and
Appendix 25
should be retained;
- distress and safety frequencies should be retained;
- in the frequency bands assigned to the MMS stations with application of digital
technologies administrations can assign frequencies to the stations for Morse
telegraphy subject to the condition that no harmful interference is caused to, and no
protection is claimed from the stations using digital technologies.
- in the frequency bands assigned to the stations for Narrow-Band Direct-Printing
(NBDP) during the transition period the priority of NBDP over digital technologies is
retained. After the transition period stations using NBDP can be used subject to the
condition that no harmful interference is caused to, and no protection is claimed from
the stations using digital technologies (see also section 1/1.9/5 of the draft CPM
Report)

• To protect the primary services in the band 37-38 GHz from interference
resulting from aeronautical mobile service operations, taking into account
the results of ITU-R studies, in accordance with Resolution 754 (WRC-07).
• RCC CAs are in favour of the restriction of the mobile service allocation in
the band 37-38 GHz to land- and maritime mobile services only (see also
Method A of the draft CPM Report).
ACP WG-F

1.14
• To consider requirements for new applications in the radiolocation service
and review allocations or regulatory provisions for implementation of the
radiolocation service in the range 30-300 MHz, in accordance with
Resolution 611 (WRC-07).
• RCC CAs propose to allocate the frequency band 154-156 MHz to the
radiolocation service on a primary basis providing necessary protection for
the FS and MS systems and limiting application of this service by detection
of space objects (see also Method A of the draft CPM Report).

•
To consider possible allocations in the range 3-50 MHz to the radiolocation service for
oceanographic radar applications, taking into account the results of ITU R studies, in accordance
with Resolution 612 (WRC 07).
•
1. RCC CAs do not object to the allocation to the radiolocation service of certain frequency
bands
up to 600 kHz each in the frequency band 3-50 MHz providing compatibility with other services
allocated in this band.
2. RCC CAs are of the view that it is possible to allocate to the radiolocation service on the
primary basis a number of frequency bands in the range 3 – 44 MHz (3155-3200 kHz, 4438-4650
kHz, 5060-5450 kHz, 7450-8100 kHz, 9040-9400 kHz, 9900-9995 kHz, 12100-12230 kHz,
13410-13570 kHz, 13870-14000 kHz, 14350-14990 kHz, 15800-16350 kHz, 22855-23200 kHz,
24000-24890 kHz, 25010-25070 kHz, 25210-25550 kHz, 26175-27500 kHz, 39-39.986 MHz,
40.02-40.98 MHz and 41.015-44.0 MHz), limited to the oceanographic radar applications subject
to
the restriction of e.i.r.p to 25 dBW and agreement to its usage from the concerned
Administrations
(see also Method A of the draft CPM Report).
3. RCC CAs are of the view that the frequency bands in the range 44 – 47.5 MHz should not be
allocated to the radiolocation service for oceanographic radar applications.

•
To consider regulatory measures and their relevance, in order to enable the introduction of
software-defined radio and cognitive radio systems, based on the results of ITU-R studies, in
accordance with Resolution 956 (WRC-07).
•
1. RCC CAs are of the view that cognitive radio systems (CRS) and software defined
radio (SDR) are the technologies used by stations of some radiocommunication
services. Such use should be in accordance with the provisions of the Radio
Regulations specified for these services for the relevant frequency bands. RCC CAs
consider that there is no need in changing Articles of the Radio Regulations for the
use of CRS and SDR
2. RCC CAs are of the view that decisions on the possibility to introduce these
technologies (SDR and CRS) and evaluation of necessity to change regulatory
provisions should be taken on the basis of studies on measures which could provide
protection of the stations already used within existing allocations.
3. RCC CAs support the development of WRC Resolution containing guidance on
further ITU-R studies on deployment and use of cognitive radio systems
4. RCC CAs do not support new Agenda Item for WRC-16 on CRS.
5. RCC considers that during the studies of implementation and use of the cognitive
radio systems it is necessary to study the cases when CRS is used in the services
shared with space services (spaceto- Earth), radiodetermination service, the services
using passive sensors (radio astronomy service, EESS, SRS) and safety services due to
increase of possibility of harmful interferences

• To consider a primary allocation to the radiolocation service in
the band 15.4-15.7 GHz, taking into account the results of ITUR studies, in accordance with Resolution 614 (WRC-07).
• RCC CAs consider that additional allocation in the band 15.415.7 GHz to the radiolocation service is possible on condition
of protecting stations perating within existing allocations in
the affected frequency bands.
ACP WG-F

1.22
• To examine the effect of emissions from short-range devices on
radiocommunication services,
• in accordance with Resolution 953 (WRC-07).
• 1. RCC supports the continuation of ITU-R studies in accordance with the
relevant WRC Resolution for SRD on impacts of emissions from shortrange devices (SRD) on radiocommunication services for purpose of global
of regional harmonization of the frequency bands and technical conditions
of work of SRD which can be moved abroad and create harmful
interference to radiocommunication services.
• 2. RCC CAs believe that for exclusion of impact of emissions from some
SRD types (for example, RFID) on radio services, the development and
application of an individual ITU-R Recommendation (s) on technical
characteristics and conditions of these SRD types use is needed.
• (see also Method B of the draft CPM Report).

1.23
• To consider an allocation of about 15 kHz in parts of the band 415526.5 kHz to the amateur service on a secondary basis, taking into
account the need to protect existing services.
• 1. RCC CAs consider that additional allocation of a frequency band
to the amateur service on a secondary basis in the band 415 –
526.5 kHz should be made on condition of providing protection of
services to which this band is currently allocated including
frequency assignments in the Plans of GE-85 Agreement for МMS
and ARNS.
• 2. RCC CAs are of the view that Method D is appropriate for the
future discussions on this Agenda Item.
ACP WG-F

•
•
To consider possible additional allocations to the mobile-satellite service, in
accordance with
Resolution 231 (WRC 07).
•
RCC CAs consider that:
•
1. The need for additional allocations to the mobile-satellite service (MSS) should be
justified by relative requirements which could not be satisfied through the existing
MSS allocations;
2. New allocations to the MSS shall only be made in those bands of the range 4 GHz to
16 GHz where adequate protection of the incumbent terrestrial and space services is
ensured, and MSS will not claim protection from potential interference from existing
and future stations of the incumbent services;
3. Taking into account the results of sharing studies, RCC CAs are of the view that:
- sharing MSS with incumbent services in the frequency bands 7055 – 7250 MHz
(space to Earth), 8400-8500 MHz (Earth to space) and 15.43-15.63 GHz (Earth to
space) is very difficult, therefore these bands cannot be allocated to MSS;
- feasibility of sharing MSS with incumbent services in the frequency bands 5150-5250
MHz (space to Earth), 10.5 -10.6 GHz (space to Earth) and 13.25-13.4 GHz (space to
Earth) is still not fully studied therefore further detailed investigations are required;
- making allocations to the MSS in other bands in the range 4 GHz to 16 GHz are not
advisable.
