WRC-15 GENERAL INFORMATION

3275 participants attended WRC-15, including:

• 2780 participants from 162 Member States, and

495 participants representing 130 other entities, including

industry, which also attended as observers

678 Documents including 2888proposals were submitted

before WRC-15. Two thirds (66%) of those were common proposals (either regional or

multi-country).

WRC-15 addressed over 40 topics related to frequency allocation and frequency

sharing for the efficient use of spectrum and orbital

resources.

WRC-15 MAIN RESULTS FOR SPACE SERVICES

• Better balance between uplink/downlink and between Regions

• Development of various applications e.g. VSAT, video distribution, broadband networks, internet service, satellite news gathering, backhaul link etc

• Protection of incumbent services

New allocations for the FSS

in Ku-band (250MHz/300MHz)

• The long term availability of the spectrum for feeder links of non-GSO systems in MSS with sufficient protection to existing ARNS stations

No limitation of primary allocation for FSS for feederlinks of

MSS non-GSO in the 5GHz band

• In combination with existing EESS downlink allocation in 8 025-8 400 MHz this new allocation will lead to simplified on-board architecture and operational concepts for future missions of EESS

New primary EESS up link allocation limited to tracking, telemetry and command (TT&C)

in the 7 190-7 250MHz band(34% increase)

• Facilitation rendezvous and docking maneuvers which leads to safety of human life in a manned vehicle

• No change to the conditions to protection of fixed and mobile Service

Removal of the 5 km distance limitation on use of 400MHz band for Extra Vehicular

Activities

WRC-15 MAIN RESULTS FOR SPACE SERVICES

• Additional bandwidth for downlink data transmissions of the next-generation satellites in the MMSS

• Protection of Fixed and Mobile Service

New allocation to MMSS in 7 375 – 7 750 MHz

in the space-to-Earth direction

• Increased use and further development of ESVs in C-band with sufficient protection to the terrestrial services

Possibility to use smaller (1.2m) antenna for ESVs transmitting

in C-band

• Increased use and further development of ESIM in the frequency bands 19.7-20.2 and 29.5-30.0 GHz in all Regions with sufficient protection to other GSO satellite networks and terrestrial services

Set conditions for Earth Station In Motion communication with GSO

FSS space stations in 19.7-20.20.2, 29.5-30.0 GHz

in all Regions

WRC-15 EXAMPLES EARTH EXPLORATION-SATELLITE SERVICE (ACTIVE) IN 8-9 GHZ

• New primary EESS(active) allocations totally of 600 MHz in the 9 200-9300MHz, 9 900-10 000MHz and 10.-10.4GHz bands (100% increase)

Development of modern broadband sensing technologies that provides high quality measurements in all weather conditions with enhanced applications for disaster relief and humanitarian aid, large-area coastal surveillance

Facilitate introduction of new technology and applications which increase quality of life

• Allocation of bands adjacent to the existing 600MHz allocation Increase efficient use of spectrum and orbital resources

• Worldwide allocation Achieve simple and universal rules

Background

• EESS (active) bandwidth in 8-9 GHz was 600MHz. Growing demand for higher resolution to satisfy global environmental monitoring raised the need to increase the bandwidth up to 1200 MHz in total.

Results of WRC-15

WRC-15 EXAMPLES EARTH EXPLORATION-SATELLITE SERVICE (ACTIVE) IN 8-9 GHZ

• Inferior status with respect to incumbent services (radionavigation and radiolocation)

• PFD limits in the new bands Provision to protect existing and future fixed and mobile stations

• Protection of Space Research service and Radio Astronomy outside the band through practical arrangement to avoid interferences described in ITU-R Recommendations

• No harmful interference to incumbent

• Increase efficient use of spectrum and orbital resources

• Maintain stability of regulatory environment

• Article 9.21 procedure

• Accommodate different needs of the regions and counties where necessary

Results of WRC-15

WRC-15 EXAMPLES SATELLITE REGULATORY PROCEDURESBackground

• the use of the same space station to bring frequency assignments to geostationary satellite networks located at different orbital locations into use within a short period of time could lead to inefficient use of spectrum/orbit resources

Results of WRC-15

• New Res. 40 (WRC-15) to increase transparency when one space station is used to bring into use assignments to GSO networks at different orbital locations within a short period of time

• Obligation to inform 1) the last orbital location where the space station was used to bring into use 2) the satellite network(s) with which the frequency assignments were associated 3) the date on which the space station was no longer maintained at the previous orbital location


• Facilitate equitable access to spectrum and orbital resources

• Stability of regulatory environment

• Simple to apply and apply worldwide

WRC-19 CHALLENGES

Possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration satellite service (space-to-Earth) in the frequency band 460-470 MHz

• Regulatory certainty for Data Correction Systems which are essential for monitoring and predicting climate change, monitoring oceans and water resources, weather forecasting and assisting in protecting biodiversity, improving maritime security, while protecting incumbent fix and mobile services

Possible revision if necessary, of RR App. 30Annex 7 limitations, incl. orbital position limitations

• Possible increase of flexibility of BSS operation and efficiency of spectrum use while protecting existing FSS networks

Studies to consider the use of the bands 17.7-19.7 GHz (s-E)and 27.5 29.5 GHz (E-s) by earth stations in motion communicating with GSO space stations in the FSS and take appropriate action

• Possible provisions to satisfy needs for Global broadband mobile satellite communication while protecting existing services

Studies on development of a regulatory framework for non-GSO FSS systems that may operate in the bands 37.5-39.5 GHz (s-E), 39.5-42.5 GHz (s-E), 47.2-50.2 GHz (E-s) and 50.4-51.4 GHz (E-s)

• Regulatory certainty for non-GSO FSS systems in V band like those in Ku and Ka bands while protecting GSO and incumbent services

WRC-19 CHALLENGES

Timely availability of wide and contiguous blocks of spectrum for IMT-2020 in the frequency range between 24.25GHz and 86GHz

Necessary regulatory actions for HAPS (high-altitude platform stations) within existing allocation and new bands: 38-39.5 GHz on global level & 21.4-22GHz and 24.25-27.5 in Region 2

• Maintain harmful interference free environment (protection of incumbent services)


• Simple to apply and apply worldwide

• Accommodate different needs of the regions and counties where necessary

Broadband applications to be shared with space services

WRC-19 CHALLENGES

• Current practice (One NGSO satellite at one orbital plane, Capable to transmit or receive frequency assignment, 90 days of operation) is not clearly defined in the RR unlikely the case for GSO

• Current practice might result in possible spectrum warehousing / “fictitious frequency assignments”


• Facilitate equitable access to spectrum and orbital resources



Satellite Regulatory issues

Definition of BRINGING INTO USE of NGSO system

WRC-19 CHALLENGES

Range of changes of characteristics allowed for NGSO during coordination without losing date priority

Satellite Regulatory issues

• No tolerance defined for orbital characteristics for NGSO

• Current identification of coordination requirements is based on frequency overlap

• No agreed criteria to measure increase of interference • Increase efficient use of spectrum and orbital resources
