6 AGENDA ASPECTS OF EFFICIENT USE OF SPECTRUM AND ORBIT RESOURCES

7 WHAT DRIVES THE EFFICIENT USE OF THE SPECTRUM/ORBITS? REGULATION TECHNOLOGY DEVELOPMENT EFFICIENT USE OF SPECTRUM/ORBIT

8 The Motivation REGULATION 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

9 The Method: WRC Process and the RR Updating the ITU Radio Regulations on the use of spectrum/orbit at each WRC REGULATION The Radio Regulations: Frequency Allocation Coordination and registration procedures Technical characteristics and limitations of stations 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: REGULATION 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 EFFICIENT USE OF SPECTRUM/ORBIT

11 The Motivation TECHNOLOGY DEVELOPMENT

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: Candidate band Potential sharing band Allocation in ITU Region GHz GHz FSS (E-s) GHz GHz FSS (s-e) GHz GHz FSS (s-e) GHz GHz FSS (E-s) Note: the GHz ( the 26 GHz band ) has been identified as a pioneer band for 5G mm-wave use in Europe.

22 IMT vs FSS : C-BAND SHARING SCENARIO (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 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
