8. The Motivation
 Article 44 of the ITU Constitution:
“Member States shall bear in mind that radio frequencies
and any associated orbits… are limited natural resources
and that they must be used rationally, efficiently and
economically, in conformity with the provisions of the Radio
Regulations…”
 Article 45 of the ITU Constitution:
“All stations…must be established and operated in such a
manner as not to cause harmful interference to the radio
services or communications of other Member States…”
REGULATION

9. The Method: WRC Process and the RR
 Updating the ITU Radio Regulations on the use of
spectrum/orbit at eachWRC
 The Radio Regulations:
 Frequency Allocation
 Coordination and registration procedures
 Technical characteristics and limitations of stations
REGULATION
The Result
 Improvement in regulatory certainty  support satellite projects’
long lifecycle
 Spectrum harmonization  economies of scale

10. Examples of recent regulatory improvements towards
the Efficient Use of Orbit/Spectrum:
 No more API submissions  Less “paper” satellites
 Reduction of the Coordination Arc in the C/Ku bands and
adoption of PFD criteria outside the arc  Improvement in
reduction of unnecessary coordination
 Introduction of ESIMs in the Ka-band  Addressing industry
developments

20. AGENDA
USE CASE 1: IMT AND FSST

21. WRC-19 AI1.13 : FURTHER SPECTRUM IDENTIDICATION FOR IMT
 Over 33 GHz of spectrum are under study
 Potential identification of IMT in frequency bands where FSS is allocated as a primary
service:
Note: the 24.25-27.5 GHz (“the 26 GHz band”) has been identified as a pioneer band
for 5G mm-wave use in Europe.
Candidate band Potential sharing band Allocation in ITU Region 1
24.25-27.5 GHz 24.65-25.25 GHz FSS (E-s)
37.5-40.5 GHz 37.5-40.5 GHz FSS (s-E)
40.5-42.5 GHz 40.5-42.5 GHz FSS (s-E)
42.5-43.5 GHz 42.5-43.5 GHz FSS (E-s)

22. (Possible) 5G BS parameters:
Power: 5W
Carrier BW: 20 MHz
Gain: 5 dBi
Rooftop antenna 2m
FSS ES parameters:
Antenna Gain: 34 dBi
Carrier BW: 1 MHz
IMT vs FSS : C-BAND SHARING SCENARIO
5G station is to be located at 1-12 km away from a satellite ES
to meet the criteria for compatibility

23. IMT vs. FSS : mm-wave bands
(Possible) 5G BS parameters:
Power: 5W
Carrier BW: 100 MHz
Gain: 5 dBi
Rooftop antenna 2m
FSS ES parameters:
Antenna Gain: 45 dBi
Carrier BW: 100MHz
Power: 100W
Red contour: 5G BS “restricted” area
around FSS ES at 40 GHz  much smaller
than in C-band
Blue coverage:Transmitting ES exceeds the
compatibility criteria to a 5G BS at 25 GHz

31. Summary
 The drivers of efficient use of spectrum/orbit originate both from
regulation and industry technology trends
 The use of appropriate radio engineering tools is mandatory for radio
services’ coexistence studies and consequent informed decisions on the
regulations of radiocommunications.
