[]{#__RefHeading___Toc166347444 .anchor}**Agenda Item 1.2**

To consider allocations and regulatory issues related to the Earth
exploration-satellite (passive) service, space research (passive)
service and the meteorological satellite service in accordance with
Resolutions **746  (WRC‑03)** and **742 (WRC‑03**).

**Proposals for Agenda Item 1.2**

##### Background information 

[]{#__RefHeading___Toc166347445 .anchor}B) Resolution 746: Use of the
frequency band 18-18.4 GHz.

*Resolves 1*

> *to invite ITU‑R to conduct sharing analyses between geostationary
> meteorological satellites operating in the space-to-Earth direction
> and the fixed, fixed-satellite and mobile services in the band
> 18-18.4 GHz to define appropriate sharing criteria with a view to
> extending the current 18.1-18.3 GHz geostationary meteorological

> contiguous spectrum;*

This proposal addresses *resolves 1* of Resolutions **746**
**(WRC‑03)**, "to invite ITU-R to conduct sharing analyses between
geostationary meteorological satellites operating in the space-to-Earth
direction and the fixed, fixed-satellite and mobile services in the band
18.0-18.4 GHz to define appropriate sharing criteria with a view to
extending the current 18.1-18.3 GHz geostationary meteorological
satellite allocation in the space-to-Earth direction to 300 MHz of
contiguous spectrum." Presently the meteorological-satellite (MetSat)
service (space-to-Earth), limited to the geostationary-satellite orbit
(GSO), is allocated by footnote **5.519** in the band 18.1-18.3 GHz. The
band is allocated on a primary basis to the fixed-satellite service
(FSS), the fixed service and the mobile service in all three Regions and
these allocations also exist for these same services in the band
17.8-18.1 GHz in all Regions. In both bands, the FSS is allocated in
both the space-to-Earth and Earth-to-space directions. Additionally, in
the 18.1-18.4 GHz band, the FSS (space-to-Earth) allocation has
associated with it Nos. **5.484A** and **5.516B**. The first provision
applies to non-Geostationary FSS satellite systems. The latter provision
states that the band 18.3-19.3 GHz has been identified for use by
high-density applications in the FSS in Region 2.

The design of the next generation GSO meteorological satellites has been
optimized to maximize the level of homogeneity between FSS and Metsat
systems. It is envisioned that this would maximize compatibility and
facilitate coordination under No. **9.7** for operation of both types of
systems in the space-to-Earth direction.

Sharing between Fixed service point-to-point systems and MetSat Earth
stations under line-of-sight conditions is feasible with an angular
off-pointing of typically around 2-2.5 degrees and a separation distance
of typically 4-9 km. For point-to-multipoint systems (out stations),
sharing is possible with no or very little angular off-pointing. Values
may range between 0 degrees and 0.9 degrees and a separation distance of
typically 4 to 7 kilometers is required. Point-to-multipoint central
stations do not require off-pointing. Given the small number of
geostationary MetSat systems and their corresponding Earth stations
(approximately 5 per Region) careful selection of the location of
meteorological Earth stations should facilitate coordination with fixed
service stations. To facilitate coordination with the fixed service,
Table **8-d** of Appendix **7** would have to be amended in order to
provide the required parameters for the determination of coordination
distance for a receiving MetSat Earth station in the 18.0 -- 18.3 GHz
band.

In accordance with No. **5.516** the band 18.0-18.1 GHz in the
Earth-to-space direction is used for feeder links for the
broadcasting-satellite service. Compatibility studies have been
performed to estimate the typical required separation distances in
reverse band sharing situations between receiving MetSat earth stations
and transmitting BSS feeder uplink stations. In the worst case, it has
been determined that around 40 km separation is required. Therefore it
is expected that with some care in situating the limited number of
MetSat receive stations international coordination would rarely be
required under No. **9.17A**.

While the expected design of the GSO MetSat satellite networks
envisioned for operation in the 300 MHz wide band appears to be
generally compatible with FSS systems being implemented, it would appear
that, for Region 2, operating MetSat systems below 18.3 GHz would avoid
several potential difficulties. Given the desire to have a common MetSat
allocation in all three Regions, it is proposed to expand the additional
allocation in No. **5.519** from 18.1-18.3 GHz to 18.0-18.3 GHz,
including the limitation to geostationary satellites and the requirement
to meet the current applicable power flux density limits as given in RR
Table **21-4** for the MetSat service in the band 18.1-18.3 GHz in the
new 100 MHz extension.

In addition, ITU-R studies have shown that, in conjunction with
extending the MetSat allocation, extending the existing FSS coordination
arc principle in this band to the case of MetSat systems coordinating
with FSS networks has the potential to reduce the workload of the Bureau
in identifying affected administrations and fulfils the purposes
envisioned by Resolution **901 (WRC-03)**. As such, a consequential
modification to Table **5-1** of Appendix **5** to include this change
is also proposed. It is noted that as with the current No. **9.7**, an
administration may request, pursuant to No. **9.41**, to be included in
requests for coor­dination involving the MetSat or FSS service in this
band, indicating the networks for which the value of *T*/*T* calculated
by the method in § 2.2.1.2 and 3.2 of Appendix **8** exceeds 6%.

**5.519** *Additional allocation:  *the band
18.[0]{.underline}~~1~~-18.3 GHz is also allocated to the
meteorological-satellite service (space-to-Earth) on a primary basis.
Its use is limited to geostationary satellites and shall be in
accordance with the provisions of Article **21**, Table **21-4**.

**Reasons**: To meet the bandwidth requirement for third generation
meteorological-satellites, an extension of the current MetSat service
allocation (18.1-18.3 GHz) by 100 MHz is proposed. This expansion will
provide greater flexibility for the meteorological-satellite service and
extend the current criteria (i.e., the limitation to geostationary
satellites and the requirement to meet the provisions of Article **21**,
Table **21-4**) to protect existing services. The sub-band 18.0-18.1 GHz
is chosen due to the favorable sharing conditions compared to the
sub-band 18.3-18.4 GHz where coexistence with ubiquitous HDFSS systems
could prove to be challenging.

**Reasons:** Consequential modification to the additional MetSat service
allocation in the band 18.0-18.1 GHz. ITU-R studies have shown that
extending the ±8º coordination arc, currently applicable to FSS networks
in this band, to the meteorological-satellite (MetSat) services in this
band would reduce the workload of the Bureau in identifying affected
administrations and the number of unnecessary coordinations for such
systems while maintaining the rights of administrations to be included
in requests for coordination involving the MetSat service or FSS in this
band.

# **Agenda Item 1.3**

# 

# In accordance with Resolution 747 (WRC-03), consider upgrading the radiolocation service to primary allocation status in the bands 9 000-9 200 MHz and 9 300‑9 500 MHz, and extending by up to 200 MHz the existing primary allocations to the Earth exploration-satellite service (active) and the space research service (active) in the band 9 500‑9 800 without placing undue constraint on the services to which the bands are allocated.

[]{#__RefHeading___Toc166347447 .anchor}A) The upgrade of Radiolocation
Service in the band 9000-9200 MHz. and 9300-9500 MHz.

##### Background information

As identified in Resolution **747** **(WRC-03)**, there is a need to
provide contiguous primary spectrum around the 9 GHz band in order for
existing and planned radiolocation systems to satisfy their required
missions. Changes in technology and emerging requirements for increased
image resolution and increased range accuracy necessitate wider
contiguous emission bandwidths. Therefore, there is a need to upgrade
the status of frequency allocations to the radiolocation service in the
frequency range 9 000-9 200 MHz and 9 300-9 500 MHz.

The bands 9 000-9 200 MHz and 9 300-9 500 MHz are allocated on a primary
basis to aeronautical radionavigation and radionavigation, respectively.
The Radio Regulation No. **4.10** recognizes radionavigation as a safety
service. The radiolocation services and the radionavigation service have
demonstrated compatible operations over many years through the use of
similar system characteristics such as low-duty cycle emissions,
scanning beams and interference reduction techniques. For example, past
operational experience in the 2 900-3 100 MHz band as found in Report
ITU-R M.2032 "Tests illustrating the compatibility between maritime
radionavigation radars and emissions from radiolocation radars in the
band 2 900 - 3 100 MHz" confirms that it is possible to mitigate
interference from radiolocation radars to maritime radionavigation
radars in the band.

Some studies have been completed within ITU-R WP 8B that characterize
the technical performance and protection criteria of radiolocation and
radionavigation systems that ensure compatible operations in the bands 9
000-9 200 MHz and 9 300-9 500 MHz. Recommendation ITU-R M.1313 contains
the technical characteristics and protection criteria for maritime
radars in the band 9 300-9 500 MHz and that Recommendation ITU-R M.1372
identifies interference reduction techniques which enhance compatibility
among radar systems.

The ITU-R studies that have been completed on radionavigation radars and
emissions from radiolocation radars in the band 9 000--9 500 MHz
illustrate compatibility between the two services in this band. These
studies indicate that typical radionavigation radars can suppress
emissions from other radars, even when the radars receive interference
with very high interference-to-noise (I/N) ratios if the unwanted pulsed
waveform is asynchronous and has a low effective duty cycle. These study
results support the successful historical sharing experience between the
services in the 9 000-9 500 MHz band. Therefore a primary allocation for
radiolocation can be added to the 9 000 - 9 200 and 9 300 - 9 500 MHz
bands.

[]{#__RefHeading___Toc166347448 .anchor}B) The 200 MHz extension of the
primary EESS (active) and SRS (active) allocations.

**Background information**

The band 9 500-9 800 MHz is allocated on a primary basis to the Earth
exploration-satellite (EESS) (active), space research (SRS) (active),
radiolocation and radionavigation services. In order to satisfy global
environmental monitoring requirements for increased resolution, EESS
(active) and the SRS (active) allocations require an increase of 200
MHz. This additional bandwidth will greatly improve the resolution of
the features for global monitoring and for environmental and land-use
purposes.

The ITU-R studied the compatibility between EESS (active) and the
existing services in the two bands identified by Resolution **747
(WRC-03)** for consideration as extension bands.

Results of ITU-R tests and measurements indicate that representative
radiolocation and radionavigation radars do not suffer any performance
degradation due to any of the representative EESS (active) waveforms.
These various ITU-R compatibility studies combined with tests and
measurements indicate that sharing is feasible in the additional 200 MHz
of spectrum between the EESS (active) and existing services in either
the 9 300-9 500 MHz band or the 9 800-10 000 MHz band. In addition,
these studies demonstrate that narrow band (less than 300 MHz) SAR
present higher interference potential compared to wide band (300 MHz or
greater) SAR extending over the whole 9300-9800 MHz band. With respect
to sharing between the EESS (active) and the fixed service, ITU-R
studies have shown that interference from a distribution of FS
transmitters operating in the 9 800-10 000 MHz band did not exceed the
interference threshold of a spaceborne SAR.

Recognizing further that narrow bandwidth (less than 300 MHz) SAR can
operate in the existing frequency band (9 500 - 9 800 MHz) and that the
requested extension is only justified for SAR systems requiring more
than 300 MHz bandwidth, a limitation of such 200 MHz extension to these
wideband (300 MHz or greater) SAR systems could limit the risk of
interference to meteorological radars while responding to the need for
200 MHz EESS extension to, as expressed in the above background section,
*"greatly improve the resolution of the features for global monitoring
and for environmental and land-use purposes".*

Since the SRS (active) systems operate in the vicinity of planets and
celestial bodies other than the Earth or as experimental platforms for
future EESS (active) systems, SRS (active) systems were not studied for
compatibility with any Earth-based systems. Another possible use of the
SRS (active) is as an experimental platform for a future EESS (active)
system. However, in this case, the SRS (active) system and the EESS
(active) system would be essentially the same. With respect to other
types of EESS (active) systems other than SARs, it should be noted that
precipitation radars and cloud profile radars cannot operate in this
frequency range due to the physics of their intended applications.
Altimeters, which are wideband EESS (active) systems operating at
relatively low power levels, have been shown to not cause interference
to radiodetermination systems in the 9 500‑9 800 MHz band. Results for
any extension band should be analogous.

##### **Agenda Item 1.5**

##### 

##### To consider spectrum requirements and possible additional spectrum allocations for aeronautical telecommand and high bit-rate aeronautical telemetry, in accordance with Resolution 230 (WRC-03).

**Proposals for Agenda item 1.5**

##### Background information

This agenda item addresses a growing demand for spectrum allocated for
aeronautical telemetry and associated telecommand. There is a
significant and growing shortfall in spectrum that is necessary to
conduct aeronautical telemetry. The shortfall is exacerbated by the loss
of telemetry spectrum diverted to other than telemetry applications. As
indicated in the responses to ITU-R Question 231/8, additional spectrum
is necessary due to rapidly increasing data rates associated with the
testing of new and emerging technologies. For example, newer
technologies rely increasingly on high-resolution video for monitoring
aircraft functions or increased use of computer based aircraft systems.
Without access to additional spectrum, aeronautical development would be
subject to escalating delays and costs, and the growth of aerospace
industry would be impaired (including equipment manufacturers, civilian
programs and test ranges, and airlines). New worldwide telemetry
spectrum will aid numerous countries and the international aeronautical
community as Administrations continue to support their national airlines
and some administrations initiate their own test programs. Existing
international allocations used for aeronautical telemetry will need to
remain available.

Aeronautical mobile telemetry ("AMT") is an application within the
mobile service. Depending on the extent to which new AMT spectrum
requirements can be fulfilled using primary mobile service allocations,
it is important that the viability of additional spectrum for AMT be
studied. International recognition of bands suitable for AMT will not
only encourage international harmonization of test equipment, but also
provide assurance to Administrations that, based on technical studies
conducted in the ITU-R, implementation of telemetry systems can be
accomplished by those Administrations wishing to do so without
disrupting other services using the bands. This will also enable
manufacturers to offer prospective customers aircraft with common test
equipment packages, and thus help airlines achieve additional economies
in the aircraft life-cycle cost. Moreover, by establishing conditions
under which AMT use of a band would be suitable, incumbent users of the
spectrum can be assured that they will not experience unacceptable
interference, while manufacturers and test ranges will have a measure of
additional certainty for the substantial investment in range
infrastructure that will be incurred in equipping to use new bands
deemed suitable for AMT.

The need for additional spectrum has been studied by several
administrations who indicate that the amount of additional spectrum for
aeronautical flight test telemetry is between 100 MHz and 650 MHz. The
requirement may differ depending on national and regional needs. It is
not necessary to fulfill all AMT requirements in only one band. The new
requirements for aeronautical telemetry are only in the air-to-ground
direction inasmuch as telecommand functions (i.e., ground-to-air
transmissions) can be accommodated in existing bands. In addition, this
new AMT spectrum will not be used for the protection of life and
property. The latter AMT applications will continue to be accommodated
in existing bands (see Nos. **5.342**, **5.343**, and **5.394** in the
Radio Regulations). Hence, aeronautical mobile telemetry applications in
new spectrum will not require the level of protection associated with
operations in existing telemetry bands. However, the AMT application may
be utilizing bands, such as the 6 GHz band, that are used for critical
applications such as public safety communications (including police and
fire vehicle dispatch), coordinating the movement of railroad trains,
controlling natural gas and oil pipelines, regulating the electric grid,
and backhauling wireless telephone traffic.

ITU-R WP 8B conducted a number of studies of bands that could be used to
satisfy the requirements of aeronautical telemetry applications.
Available technologies, signal fading/propagation considerations, and
the scope of agenda item 1.5 dictate that the new wideband AMT spectrum
requirements be fulfilled in the 3 GHz to 7 GHz frequency range.
Conversely, technological challenges necessitate at this juncture a
focus on bands below 16 GHz. With the cooperation of other responsible
WPs, several bands were studied for suitability to implement AMT, given
the other co-primary services in the band. Portions of these bands, such
as the 5925 - 6700 MHz band, are used for public safety communications
and other applications that require a high degree of protection. It is
expected that the implementation of telemetry may require avoiding
co-frequency operations with local services in some of the bands. This
will likely mean that the spectrum requirement for AMT would be
satisfied using portions of each of the bands studied and deemed
suitable for AMT implementation. In this context, suitable means that
AMT can be implemented compatibly with other co-primary services
utilizing the band, assuming the implementation is in accordance with
the established sharing criteria.

ITU-R studies have determined conditions under which aeronautical mobile
telemetry for flight test purposes can be implemented in these bands
without adversely affecting the operation of existing systems and
allocated services. The ability to implement AMT in some areas and in
some portions of the bands may be restricted based on deployment density
of other co-primary service stations, such as the Fixed Service (FS)
stations, in the same vicinity. In cases where AMT operations could
impact Radio Astronomy observatories, it may be possible to arrange AMT
time-sharing with those observatories to enable AMT use of the
4 825-4 835 MHz band.

In the past, terms such as "designated" or "identified" have been used
in the Radio Regulations with respect to certain technologies and bands
to encourage technology implementation on a worldwide basis without
making the use by administrations mandatory, and without establishing
any priority of use. Since the spectrum requirements and the conditions
under which AMT will be implemented can vary by administration, an
approach is proposed to simply indicate the suitability of certain bands
for the implementation of AMT based on compatibility studies. This
approach provides valuable information while maximizing the flexibility
of implementing AMT. A finding that spectrum is suitable for AMT
implementation inherently would not establish any priority of use or
preclude use of the bands by other co-primary services.

Any authorization of AMT operations within these bands would be decided
by individual administrations, and would be specifically limited to
testing of aircraft at designated flight test areas in the air-to-ground
direction within those individual countries. According to No. **5.444**
of the Radio Regulations, the 5 091-5 150 MHz band is to be used by the
MLS (Microwave Landing System) with precedence given to this
international standard system. However, to date there has been no
deployment of MLS in \[New text\] the band 5 091-5 150 MHz.

The 5 091-5 150 MHz band is already allocated to the aeronautical
radionavigation service (ARNS) on a primary basis in all Regions and is
also allocated to the fixed-satellite service (FSS) (Earth-to-space) on
a primary basis. This FSS allocation is limited to feeder links of
non‑geostationary mobile-satellite systems in the mobile-satellite
service and is subject to coordination under No. **9.11A**. Test
aircraft are not intended to use ground-to-air transmissions in this
ARNS band. Administrations are also considering the band 5 091-5 150 MHz
under agenda item 1.6 for allocation to the aeronautical mobile (R)
service (AM(R)S). Studies have shown that AMT can share with both the
FSS and the proposed AM(R)S system in the band 5 091-5 150 MHz.

In the event the Conference determines that use of the 4 400-4 940 MHz,
5 925-6 700 MHz, and 5 091-5 150 MHz bands would be suitable \[New
Text\] for aeronautical telemetry, coordination with FSS earth stations
in accordance with Article **9** of the ITU Radio Regulations would be
required

ITU-R studies have not adequately demonstrated that aeronautical
telemetry or telecommand applications could share spectrum with other
uses in the band 5 150 MHz-5 250 MHz.

Changes to Article **1** definitions of aeronautical telemetry and
aeronautical telecommand are unnecessary. This is not only the least
restrictive of the options for implementing aeronautical mobile
telemetry, but has a long and successful history in the ITU. The effort
to secure Article **1** definitions would impose substantial burdens on
the Special Committee for Regulatory and Procedural Matters and ITU
staff, as well as complicate the work of the WRC. There are also less
formal approaches to exploring the meaning of these terms as an
alternative to adopting formal definitions under Article **1** of the
Radio Regulations. To the extent any Administration should be of the
view that further clarification regarding the scope of the agenda item
would be in order, such clarification can be provided via text in the
WP8B Preliminary Draft New Report.

Remotely piloted aircraft, also referred to as unmanned aerial vehicles
("UAVs"), are envisioned by many as fulfilling a variety of civil
applications, and flying in the national airspace of numerous
Administrations within the next decade. Vehicles such as these must be
carefully tested before any such operation commences given, the obvious
safety implications associated with these flights. Additional spectrum
designated for aeronautical mobile telemetry pursuant to Agenda Item 1.5
may be utilized for the flight testing of such aircraft. Such testing is
expected to occur at designated test centers on a coordinated basis with
incumbent services. Such use does not include command and control of
UAVs in national airspace. Consideration of the spectrum needs of UAVs
operating in national airspace should not be considered under Agenda
Item 1.5.

It is noted that, to date, with reference to Resolution **230** Resolves
2, no current secondary allocations of the mobile service have been
identified for upgrade to primary.

[]{#__RefHeading___Toc166347450 .anchor}**Agenda Item 1.13**

Taking into account Resolutions **729 (WRC‑97)**, **351 (WRC‑03)** and
**544 (WRC‑03)**, to review the allocations to all services in the HF
bands between 4 MHz and 10 MHz, excluding those allocations to services
in the frequency range 7 000-7 200 kHz and those bands whose allotment
plans are in Appendices **25**, **26** and **27** and whose channelling
arrangements are in Appendix **17**, taking account of the impact of new
modulation techniques, adapting control techniques and the spectrum
requirements for HF broadcasting.

**Proposals for Agenda item 1.13**

**Background information**

There are multiple services allocated to the HF bands between 4MHz and
10MHz, including aeronautical mobile (OR), aeronautical mobile (R),
amateur, broadcasting, fixed, maritime mobile and mobile services. ITU-R
studies on this agenda item have been divided into five issues as
discussed below.

-   Issue A - Resolution **729 (WRC-97)**

-   Issue B - Resolution **729 (WRC-97)**

-   Issue C - Resolution **351 (WRC-03)**

-   Issue D - Resolution **544 (WRC-03)**

-   Issue E - General review of 4-10 MHz not covered by the Resolutions
    above

[]{#__RefHeading___Toc166347451 .anchor}Issue (A) and (B): Resolution
729 (WRC-97) resolves 2 and 3

Use of frequency adaptive systems in the MF and HF bands.

-   *resolves 2 -* that frequency adaptive systems shall automatically
    limit simultaneous use of frequencies to the minimum necessary for
    communication requirements.

-   *resolves 3 -* that with a view to avoiding harmful interference,
    the system should evaluate the channel occupancy prior to and during
    operation

This Resolution outlines the use of frequency adaptive systems in the MF
and HF bands and invites the ITU-R to pursue studies on the subject to
achieve optimum operational performance and compatibility and to report
on the results of these studies to a future world radiocommunication
conference.

Adaptive HF systems have been in use for over 20 years and no special
consideration in the ITU Radio Regulations is required to fully
implement adaptive HF systems. By their nature these systems already
automatically limit simultaneous use of frequencies to the minimum
necessary for communication requirements. These systems also
automatically avoid harmful interference by evaluating the channel
occupancy prior to and during operations. ITU-R has also developed new
recommendations and reports as well as revisions to existing
recommendations describing these systems and providing technical
characteristics of representative systems.

RESOLUTION 729 (Rev WRC ~~97~~ [07]{.underline})

**Use of frequency adaptive systems in the MF and HF bands**

The World Radiocommunication Conference (Geneva,
~~1997~~[2007]{.underline}),

considering

*a)* that the efficiency of spectrum use will be improved by the use of
frequency adaptive systems in the MF and HF bands shared by the fixed
and the mobile services;

*b)* that trials of frequency adaptive systems which have been
undertaken during the past 20 years have demonstrated the feasibility of
such systems and their improved spectrum efficiency;

*c)* that such improved efficiency is attained through:

-- shorter call set-up and improved transmission quality by selection of
the most suitable assigned channels;

-- reduced channel occupancy, permitting the same channels to be used by
different networks, yet decreasing the probability of harmful
interference;

-- minimization of the transmitter power required for each transmission;

-- continued optimization of the emissions owing to the sophistication
of the systems;

-- simple operation by the use of intelligent peripheral equipment;

-- reduced need for skilled radio operators;

*d)* that ~~following Resolution **23 (WRC-95)**~~[^1]~~,~~ the
Radiocommunication Bureau no longer undertakes examination with respect
to the probability of harmful interference caused by new assignments
recorded in the Master International Frequency Register (MIFR) in the
non-planned bands below 28 MHz;

*e)* that frequency adaptive systems will actively contribute to the
avoidance of inter­ference since, when other signals are observed on the
channel, the frequency adaptive system will move to another frequency,

> *resolves*

1\. that, in authorizing the operation of frequency adaptive systems in
the MF and HF bands, administrations shall:

1.1 make assignments in the bands allocated to the fixed and mobile
services;

1.2 not make assignments in the bands:

-- allocated exclusively to the maritime or aeronautical mobile (R)
services;

-- shared on a co-primary basis with the broadcasting service,
radiodetermination service or the amateur services;

-- allocated to radio astronomy;

1.3 avoid use which may affect frequency assignments involving safety
services made in accordance with Nos. **5.155**, **5.155A** and
**5.155B**;

1.4 take into account any footnotes applicable to the proposed bands and
the implications regarding compatibility;

2\. that frequency adaptive systems shall automatically limit
simultaneous use of frequencies to the minimum necessary for
communication requirements;

3\. that, with a view to avoiding harmful interference, the system
should evaluate the channel occupancy prior to and during operation;

4\. that frequency adaptive systems shall be notified to the Bureau in
accordance with the provisions of Article **11**,

~~invites ITU-R~~

~~1 to pursue its studies on the subject (see, for example, Questions
ITU-R 204-1/1, ITU‑R 147-1/9, ITU-R 205/9 or ITU-R 214/9) with a view to
achieving optimum operational performance and compatibility;~~

~~2 to report on the results of these studies to a future world
radiocommunication conference,~~

instructs the Director of the Radiocommunication Bureau

to make the necessary arrangements, as soon as practicable, for the
notification of frequency assignments to adaptive systems and for their
recording in the MIFR, taking into account the studies already
undertaken.

**Reasons:** ITU-R working parties have studied the subject of frequency
adaptive systems in the HF/MF band and have developed recommendations,
reports and handbooks addressing various issues.

[]{#__RefHeading___Toc166347452 .anchor}Issue (D): Resolution 544
(WRC-03)

-   Identification of additional spectrum for the broadcasting service
    in the HF bands.

-   To carry out studies on this matter, taking into account technical,
    operational, economic and other relevant factors, including the
    appropriate transitional arrangements, and how the introduction of
    digital emissions will affect the HF broadcasting requirements and
    how such reallocations will affect other services using these bands

**Background information**

Under Resolution **544** **(WRC-03)**, the broadcasting service
identified a requirement for 250 kHz of additional spectrum to clear
co-channel collisions and up to 800 kHz to clear both the co-channel and
adjacent channel collisions

In the past, WARC-79 allocated 125 kHz of new HF spectrum to the
broadcasting service, and WARC-92 an additional 690 kHz of which 200 kHz
is in the 4 to 10 MHz range to become available on 1 April 2007. Also,
at WRC-2003, the broadcasting service was provided an additional 50 kHz
in Region 2 to be re-allocated in 2009. As a result of these Conference
decisions the incumbent fixed and mobile services lost an equivalent
amount spectrum for their operations. Users of the affected bands,
already scheduled to go to the broadcasting service in 2007 and 2009,
will migrate where practical to adjacent fixed and mobile service bands,
thereby increasing channel occupancy in those bands. Presently, some
administrations are already having difficulties finding replacement
spectrum for the bands the fixed and mobile services will be required to
vacate in 2007 and 2009.

HF bands and fixed and mobile services already experience congestion and
channel non-availability. The spectrum is ideal and necessary for fixed
and mobile applications as it can provide communication range and go
around obstructions and hills. Also, in most countries, existing HF
allocations are used to meet government emergency and security
requirements that support essential national and international services.
HF provides for point-multipoint connectivity and allows a number of
participants to monitor and co-ordinate joint activities. There are no
direct alternatives for this particular capability, and this requirement
will continue and may increase.

The use and demand for HF spectrum for fixed and mobile applications is
increasing with the advent of new, higher speed HF modems, Automatic
Link Establishment (ALE) equipment and banding (using several channels
to enlarge bandwidth) to increase capacity. HF e-mail is also increasing
in demand as it is cost competitive with satellite communications. New
technologies now make HF communications viable and affordable for many
applications such as data exchange, fax, messaging, imagery, and voice.
The convergence in digital communications (data, voice, sound and image)
is giving rise to technology trends in the HF bands that are not only
rapid but also unpredictable and administrations face greater spectrum
planning challenges to deal with this convergence.

**Frequency allocations**

**4-10 MHz**

**Reasons:**

a)  Supports the protection of the incumbent HF services and their
    current allocations.

b)  Improvements in HF technology have increased the importance of HF
    radiocommunications for a variety of users:

-   The use and demand for HF spectrum for fixed and mobile applications
    is increasing.

-   HF e-mail is increasing in demand as it is cost competitive with
    satellite communications this is due to the use of high speed HF
    modems, Automatic Link Establishment (ALE) equipment and banding
    (using several channels to enlarge bandwidth) to increase capacity.

-   New technologies now make HF communications viable and affordable
    for many applications such as data exchange, fax, messaging,
    imagery, and voice.

-   The use of fixed and mobile HF spectrum for Internet applications is
    increasing. Some HF radios specified in ETSI and IEC standards
    currently offer these Internet services; however these new
    applications require channel bandwidths larger than the current
    3 kHz available to provide the necessary quality of service.

c)  Additional spectrum for the broadcasting service would be taken from
    the current fixed and land mobile service allocations placing
    constraints on existing and growing fixed and mobile applications
    including conventional HF systems, PPDR communications and HF
    internet use.

d)  Precludes additional spectrum for the broadcasting service as a
    shared allocation with the fixed and mobile services

-   ITU-R studies lack clear conclusions showing such sharing is
    feasible

e)  Additional spectrum for the broadcasting service may indirectly
    effect the current Land Mobile Service and Aeronatical Mobile
    Service allocations as they may be forced to share by converting to
    generic mobile allocations and share spectrum with the fixed
    service.

-   ITU-R studies lack clear conclusions showing such sharing is
    feasible

f)  Additional spectrum for the broadcasting service may indirectly
    effect the current MMS allocations as the MMS may be forced to share
    spectrum with the fixed and land mobile services.

    -   ITU-R studies lack clear conclusions showing such sharing is
        feasible

g)  The availability of sufficient HF spectrum has a direct bearing on
    the reliability of HF operations when they are needed most.
    Emergency HF is used in a dynamic environment that generates rapidly
    changing requirements arising from the development of a situation.

h)  HF fixed and land mobile services have lost spectrum as a result of
    previous WRC's.

RESOLUTION 544 (WRC-03)

Identification of additional spectrum for the

broadcasting service in the HF bands

**Reasons:** The impact to the Fixed and Mobile community is too severe
to allocate additional spectrum to the broadcasters that would, in fact,
come from bands assigned to these services. In addition, the long term
need for additional broadcasting spectrum is unknown. Additional
spectrum reallocated to the broadcast service would result in congestion
to the fixed and mobile service, including the MMS. Congestion is now
present in some fixed and mobile bands. Recent operations supporting
disaster relief demonstrated fixed and mobile service requirements
exceeded the spectrum allocated to these services. Frequencies used by
the Maritime Mobile Service support general and safety related
communications as well as Ship Security Alert Systems communications and
Long Range Tracking and Identification. Any degradation of these
services would have severe consequences.

Improvements in HF technology have increased the importance of HF
radiocommunications for a variety of users. New applications used by the
Fixed and Mobile Service require additional bandwidth to allow higher
data rates. These new technologies now make HF communications viable and
affordable for many applications such as data exchange, fax, messaging,
imagery, and voice

[]{#__RefHeading___Toc166347453 .anchor}Issue (E):

-   Review the allocations to all services in the frequency range 4-10
    MHz except allocations to services in the frequency range 7 000-7
    200 kHz and those bands whose allotment plans are in
    Appendices **25**, **26** and **27** and whose channelling
    arrangements are in Appendix **17**. This section contains those
    issues that are not covered by any of the Resolutions and those
    elements where the Resolutions are interrelated.

**Background information**

Issue E is very broad and may potentially cover many sub-issues. This
proposal deals with the amateur service at 7200-7300 kHz in Region 2
only.

Most administrations recognize the amateur service's support in serving
public protection, humanitarian and disaster relief agencies as well as
non-government organizations such as the Red Cross and Red Crescent
Movement, as provided in the changes to Article **25** made at WRC‑03.

For the 7 MHz band, WRC‑03 realignments will increase the worldwide
amateur allocation from 100 kHz to 200 kHz (7000-7200 kHz) effective 29
March 2009. In Region 2, there is a 300 kHz amateur service allocation
at 7000-7300 kHz which continues to be required in the region.

#### **Agenda Item 1.15**

#### To consider a secondary allocation to the amateur service in the frequency band 135.7‑137.8 kHz.

**Proposals for Agenda item 1.15**

##### Background information

At WRC-03 this agenda item was proposed by CITEL under Resolution
**26**. The conference decided to have this issue included as an agenda
item for WRC-07.

For more than two decades radio amateurs around the world increasingly
have been interested in experimenting with communications at low
frequencies. In the past ten years, approximately 40 Administrations
have given domestic Amateur Radio allocations or have authorized
experimental amateur radio communications in the low frequency range
including 73 kHz, 135.7 - 137.8 kHz, and 160- 190 kHz.

In 1997, radio amateurs in Europe were given formal authority to operate
in the LF band pursuant to CEPT Recommendation 62-01 E (Mainz 1997),
which pertains to the use of the band 135.7 -- 137.8 kHz by the Amateur
Service. Currently, radio amateurs are active in the band 135.7 - 137.8
kHz in more than 25 European countries. Operation in Russia has been
authorized in both the European and Asiatic parts of the Federation.
Furthermore, New Zealand has granted an allocation to the Amateur
Service in this band, and Australia has authorized some experimental
communication.

In Region 2, amateurs have been conducting communications in the
frequency band 135.7 - 137.8 kHz under experimental authorizations and
have taken measures to avoid interference to the operations of the
primary users of the band. With the approval of the CEPT Recommendation
in Europe, France has also authorized the use of the band 135.7 - 137.8
kHz in its Region 2 Territories, St. Pierre and Miquelon, Martinique and
Guadeloupe.

No cases of interference to other services from amateur service
operations in the frequency band 135.7-137.8 kHz have been reported and
studies show that the probability of interference to other services from
amateur LF stations with an EIRP of 1 or 2 watts, is low. The frequency
band 135.7-137.8 kHz is allocated on a primary basis to the fixed and
maritime mobile services in the three Regions and to the radiolocation
service in Region 3. Footnote **5.67** provides an Additional
allocation in Azerbaijan, Bulgaria, Mongolia, Kyrgyzstan, Romania,
Turkmenistan and Ukraine, to the radionavigation service on a secondary
basis.

ITU-R WP 9C did not find sharing problems with the amateur service at
135.7-137.8 kHz, and ITU-R WP 8A is currently drafting CPM text with
various methods to solve the agenda item.

##### Proposals

##### 

Add a secondary allocation to the amateur service in the frequency band
135.7‑137.8 kHz with an associated footnote as described below.

**5.XXX** In the band 135.7-137.8 kHz, stations in the amateur service
using frequencies in this band shall not exceed a maximum radiated power
of 1 W (e.i.r.p.).

**Reasons:**

a)  No cases of interference to other services from amateur service
    operations in the frequency band 135.7-137.8 kHz have been reported;

b)  Harmonizes with similar allocations that have been provided in some
    countries in North America, Europe, Australia and parts of Asia.

c)  Provide an opportunity for experimentation with equipment,
    techniques, antennas and propagation phenomena in a new frequency
    band heretofore unavailable to the amateur service;

d)  Provide an opportunity for experimentation of potential benefit to
    other services in keeping with the amateur service's tradition of
    contributing to the development of radiocommunications techniques
    and practices;

e)  Provide radio amateurs with the opportunity to participate in and
    contribute to an exciting new aspect of radio communications which
    would be consistent with the basis and purpose of the amateur
    service;

f)  Recognize the value of experimentation in attracting young people to
    the amateur service.
