RSPG Opinion 6:
A coordinated EU Spectrum approach for
Scientific Use of Radio Spectrum, 25-10-’06.
Objective: improve recognition
Conclusions:
Considerable societal value
Incommensurable in financial terms
Intergovernmental commitments is a European
priority
Exclusive allocations only for a limited portion of
spectrum
If sharing (for non 5.340 bands): impact on both
services shall be assessed.

Opinion 6 and WRC agenda 8.1.1 item C
Director ITU-R to Report on sector activities related to
Resolution 673 (WRC-07): Radiocommunications Use
for Earth observations applications:
Its objective: improve recognition
Res 673 has no word about Radio Astronomy
In ITU-R we develop the Report about the essential role
of observations (EESS etc. and RAS/SRS);
Sections on RAS had a slow start
Shall we change from Science to Observation Services?

RSPG Opinion 12:
Best Practices Regarding the Use of
Spectrum by Some Public Sectors,11-2-’09
Focuses on Defense, Emergency and Public
Safety, and Public Transport
Multiple approaches:
Document the rights of use by public sector
bodies;
Determine needs via ex-ante detailed audit;
Apply a “justification procedure”;
public sector bodies have to submit a detailed
explanation of their spectrum requirements.
Also: acquire service from the market, introduce
spectrum pricing etc.
•

Netherlands (1)
Change in Telecommunication Law
Public Spectrum Users have to justify their
needs on a regular basis:
Also Science Services have to submit every 3
years a plan containing their justified needs.
•

Netherlands (2)
Minister of Education and Science to specify:
Purpose and legal basis for public use use,
Organisation to use,
Inventory of required spectrum,
Time, location, conditions for use,
Further information my be requested by the
Telecom Minister.
What about proposing this in an ITU-R Report
or Recommendation?

ECC: Short Range Radar in 24 GHz
Electronic Communications Committee
Permanent in US,
Interim on 24 GHz in Europe; the European Regulation
to protect Radio Astronomy is not enforceable.
No take-off could lead to prolongation of interim
regulations
Future band: still considerable disagreement in CEPT.
Prolong on limited period in 24 GHz, and move to 77-81
GHz
Allow 10 %, or
limited period in band 26 -29 GHz and move to 77-81 GHz.

CEPT Report 36 on 24 GHz
put on hold, awaiting final decision on 26 GHz
Provisional Conclusion:
“Finally, simply by taking into account the
constraints resulting from coexistence between
SRR 24 GHz and EESS, FS & Radio Astronomy,
CEPT can conclude that existing regulation for SRR
24 GHz systems should in principle be kept without
substantial changes”
(max. 7 % , or mid 2013).

No definitions in the Radio Regulations
Any radio system may implement SDR/CRS techniques
within any radiocommunication service as long as it
operates in accordance with the provisions of the RR
applicable for that specific service in the related
frequency band.
Frequencies or frequency bands (tuning range) for
specific applications could be harmonized, as
necessary, on world wide basis in ITU-R
Recommendations or regionally.
No regulatory actions would be required for SDR .

Deployment scenarios:
If all systems in a certain band have CRS
capabilities: CRS can share on a primary basis.
In case of sharing in a band with systems not
having CRS capability: CRS use is secondary to the
use of the service having primary allocation.
Conclusion:
There is no need to exclude Radio astronomy
bands.

Other views: Cognitive and Software Radio
No change to RR’s with a WRC Resolution
providing guidance for further studies;
No future agenda item;
No change to RR’s with a WRC Resolution dealing
with the use of Cognitive Radio, further studies
within ITU-R;
Exclusion of Radio Astronomy and others until
studies are finished

CPG: Flexibility (Resolution 951)
Increase flexibility in RR while ensuring compatibility
between services: allocations to be done in the
broadest possible way under provisions to ensure
technological neutrality where possible.
Include only issues which have an international
implication in the Radio Regulations
Use of a frequency band is decided at national or
regional level, in accordance with the Radio
Regulations, noting that some use is international, or
has international implications
Develop a WRC Resolution on principles for enhancing
the international spectrum regulatory framework.

CPG: Flexibility
Current trend towards convergence of applications
within different services;
Regulations have to keep pace with developments,
while ensuring effective and efficient use of
spectrum allowing operation to be free of harmful
interference;
Decisions to modify the Radio regulations may take
a period of 4-8 years, sometimes even more.
•

ITU-R: Flexibility
Convergence Fixed - Mobile:
Do as we have done always: every WRC
Modify definitions in Article 1 to make a clear
difference:
at motion or at unspecified location is mobile;
Fixed receiver at specified point or at any point
within a specified area is Fixed Service.
CEPT: Licensing will protect RAS

ITU-R: Flexibility
General Allocation Issues:
2 views:
RR’s and WRC’s provide the means to meet
requirements of the future;
Allocate bands to the most broadly defined
service; allocate on a worldwide basis taking
into account safety, technical, operational,
economical factors
•
RFI2010, March 29-31 2010 Groningen

Flexibility for Radio Astronomy ?
In Article 5 there are 20 frequency bands
allocated to both EESS (passive), Radio
Astronomy and SRS (passive).
What about a flexible allocation to:
Observation Service (passive)?

To conclude:
Look a little bit less to the universe,
Look a little bit more to the spectrum !
