  agenda item 7.2                                
  ---------------------------------------------- ------------------------

7.2 to recommend to the Council items for inclusion in the agenda for
the next WRC, and to give its views on the preliminary agenda for the
subsequent conference and on possible agenda items for future
conferences, taking into account Resolution **801 (WRC-2000)**

Resolution 801 (WRC-2000) specified as agenda item 2.12 the following:
"to consider spectrum requirements for wideband aeronautical telemetry
in the band between 3 GHz and 30 GHz;"

Background information

The 2000 Radiocommunication Assembly approved Question ITU-R 231/8,
titled: *Operation of wideband aeronautical telemetry in bands above 3
GHz*. The 2000 Radiocommunication Assembly directed that Question ITU-R
231/8 studies be completed by 2005.

The World Radiocommunication Conference 2000 included item 2.12 in the
preliminary agenda for the World Radiocommunication Conference 05/06.
ITU-R Circular letter CA/109 was a "request for administrations and
Sector Members to supply data on existing and planned wideband
aeronautical telemetry systems operating at frequencies above 3 GHz". In
this circular letter Wideband Aeronautical Telemetry is defined as:

***"Emerging Telemetry Systems With Large Data Transfer Requirements to
Support New and Different Telemetry Capabilities (such as high
resolution video and associated data for remotely-piloted aeronautical
vehicles). It is further defined as telemetry generally requiring a
bandwidth of 20 MHz or greater."***

It should be noted that neither the wideband spectrum requirement
referenced under this agenda item, nor Question ITU-R 231/8, contemplate
a substitution for existing aeronautical telemetry allocations below 3
GHz. The requirement for these allocations will continue. Rather, this
proposal addresses new and emerging wideband requirements.

Preliminary information submitted in initial response to the Circular
letter CA/109 indicated that there are substantial requirements for
additional spectrum, for wideband aeronautical telemetry. Additional
information is being developed for the next study cycle, which will
present a complete characterization of the spectrum requirements
pursuant to Question ITU-R 231/8. Preliminary data also indicates that
the spectrum would be used for high data rate systems, such as multiple
high‑definition video links, newer forms of avionics technologies, etc.

Proposals

RESOLUTION 801 (WRC-2000)

\...

resolves to give the view

\...

**MOD** USA/12/260

2.12 to consider spectrum requirements and allocations for wideband
aeronautical telemetry in the band between 3 GHz and 16 GHz in
accordance with Resolution **\[WIDEBAND TELEMETRY\] (WRC-03)**;

**Reasons:** To provide the required focus on this agenda item so as to
align it with recent plenipotentiary decisions regarding agenda items.

**ADD** USA/12/261

draft RESOLUTION \[WIDEBAND TELEMETRY\] (WRC-03)

Consideration of mobile allocations for use by wideband aeronautical\
telemetry in the band between 3 and 16 GHz

The World Radiocommunication Conference (Geneva, 2003),

considering

*a)* that there is a need to provide global spectrum to the mobile
service for wideband aeronautical telemetry systems;

*b)* that there is an identified need for significant additional
spectrum required to meet future wideband aeronautical telemetry
demands;

*c)* that there is a need to protect existing services,

noting

*a)* that a number of bands between 3 GHz and 16 GHz are already
allocated to the mobile service, without excluding aeronautical mobile,
on a secondary basis;

*b)* that any spectrum allocated for the mobile service above 3 GHz (to
include aeronautical telemetry) is not a substitution for existing
aeronautical telemetry allocations below 3 GHz. The requirement for
which will continue,

recognizing

*a)* that there are emerging telemetry systems with large data transfer
requirements to support testing of commercial aircraft and other
airframes;

*b)* that the future technologies and performance expectations for
airborne platforms contemplate a need for real-time monitoring of large
data systems with multiple video streams (including high-definition
video), high-definition sensors, and integrated high-speed avionics;

*c)* that the 2000 Radiocommunication Assembly approved question ITU-R
231/8, titled: Operation of wideband aeronautical telemetry in bands
above 3 GHz,

further recognizing

*a)* that the 2000 Radiocommunication Assembly directed that Question
ITU-R 231/8 studies be completed by 2005;

*b)* that those studies will provide a basis for considering regulatory
changes, including additional allocations and recommendations, designed
to accommodate the spectrum requirements of aeronautical mobile
telemetry consistent with the protection of incumbent services,

resolves

that WRC-07 be invited to consider, on the basis of the studies
specified below:

1 as a matter of urgency, spectrum required to satisfy wideband
aeronautical mobile telemetry requirements above 3 GHz;

2 review, with a view to upgrading, the status of secondary frequency
allocations to the mobile service in the frequency range 3-16 GHz for
the implementation of wideband aeronautical telemetry;

3 consider allocation of frequencies to the mobile service, including
aeronautical mobile, on a primary basis in the frequency range 3-16 GHz
for the implementation of wideband aeronautical telemetry,

invites ITU-R

to conduct, and complete in time for WRC-07, appropriate studies leading
to technical, regulatory and operational measures to facilitate sharing
between aeronautical mobile telemetry and existing services taking into
account the *resolves* above.

**Reasons:** This Resolution refines the agenda item to make clear that
spectrum allocations are included within its scope, to narrow the
frequency range for study in the next cycle, and to ensure compatibility
with existing services.
