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.

 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.

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 !
