AGENDA
ASPECTS OF EFFICIENT USE OF SPECTRUM AND ORBIT
RESOURCES
WHAT DRIVES THE EFFICIENT USE OF THE SPECTRUM/ORBITS?
REGULATION
EFFICIENT USE OFSPECTRUM/ORBIT
TECHNOLOGY
DEVELOPMENT
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
The Method: WRC Process and the RR
Updating the ITU Radio Regulations on the use of spectrum/orbit at each WRC
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
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

AGENDA
USE CASE 1: IMT AND FSST
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)
(Possible) 5G BS parameters:Power: 5WCarrier BW: 20 MHzGain: 5 dBiRooftop antenna 2m
FSS ES parameters: Antenna Gain: 34 dBiCarrier 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
IMT vs. FSS : mm-wave bands
(Possible) 5G BS parameters:Power: 5WCarrier BW: 100 MHzGain: 5 dBiRooftop antenna 2m
FSS ES parameters: Antenna Gain: 45 dBiCarrier BW: 100MHzPower: 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

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.
