Spectrum Decisions Impact Satellite Use

Users/providers of satellite communications would like certainty around its use BUT spectrum decisions can & do impact service provision

u Growth of data => more spectrum being demanded & licensed for

terrestrial use

u C-Band (3.6-3.8 GHz) faces the greatest pressure u According to ITU regulations, C-Band allows both the SATELLITE & the FIXED

SERVICE (point-to-point)

u In some places, C-Band is now being shared with point-to-

multipoint/mobile/IMT which has led to interference cases

⇒ C-Band users such as the humanitarian community

& relevant govt depts are often unaware of policy decisions that may impact them

Examples of Interference

UN DOS (Dept of Operational Support) relies on C-Band for critical peacekeeping operations

u Only UN organisation to own/operate teleports worth $15m (Brindisi (IT) & Valencia (ES)) u DOS supports all UN humanitarian missions globally u Use C-Band due to RELIABILITY / COVERAGE / links back to EU (global beams rather than

spot beams in Ku/Ka band)

u Example 1: Post EU-2008 decision on Broadband Wireless Access at 3.6-3.8 GHz - DOS saw

interference between Brindisi & Somalia and worked with satellite operator to use >3.8 GHz

u Example 2: Iraq, Aug 2019: DOS used satellite at 4.055 GHz but WIMAX at 3.750 GHz

caused interference - filters used to avoid it but significant reduction in available satellite spectrum

⇒ Even if ITU rules permit FIXED P2P and SATELLITE use in C-Band ⇒ Once use becomes point-to-multipoint or IMT, causes problems for satellite

Numerous UN agencies rely on satellite networks to coordinate activities & work, send reports, voice communications, & provide WiFi for staff welfare

u Emergency Situations are increasing & with it, use of C-

Band as well

u UN Agencies relying on Satellite Services:

UN Food and Agriculture Organisation – FAO UN Children’s Fund – UNICEF UN Office for Coordination of Humanitarian Affairs – UNOCHA UN Relief and Works Agency – UNRWA World Food Program – WFP World Health Organisation – WHO UN Population Fund – UNFPA UN Development Program – UNDP International Office for Migration – IOM UN Department of Operational Support – UN DOS UN Program on HIV/AIDS – UNAIDS

A Look to the Future

Use of C-Band is not decreasing

A Look to the Future

Pressure on C-Band is increasing

Pressure to identify 3 600-3 800 MHz for IMT in Region 2 (Americas) at WRC-23 WRC-23 could upgrade mobile service to PRIMARY status in Region 1 (Europe / Africa / ME / CIS) creating even more potential for interference with satellite

WRC 2019 - Why do we care?

Any disruption to legacy bands would seriously affect our ability to deliver services to populations of concern Concerned about potential risks to core satellite services that UNHCR/other UN bodies/ NGOs rely on for emergency response & day-to-day business

u We use several communications technologies across our operations BUT there is no

• bvious replacement for SATCOMS due to location & coverage as well as resilience in

areas affected by man or nature made disasters

u UNHCR continues to use today nearly 300Mbps of space segment - primarily C-band &

Ku-band. We use L-Band for MSS and Ka-band is used for emergency networks in Syria and Yemen

u In spite of our great expectations for this technology, 5G is not a connectivity means that

we will be able to rely on in short- or long-term, as it is unlikely to cover many areas

u We look forward to using next generation systems as well including NGSO (LEO)

constellations which we believe will compare well to terrestrial networks

Conclusions

Learn Lessons & Share Best Practices

v Mozambique was eager to embrace fibre &

in the future terrestrial 5G

v They phased out satellite & were supportive

• f allocating C-Band spectrum to IMT

v At the time of Cyclone Idai they realised

how critical satellite was & how unprepared they were LESSON LEARNED:

⇒ Synchronise your NETP with national

spectrum planning to ensure continued

• peration of essential satellite services

Conclusions

What ITU Member States need to know (I)

u Satellites provide an irreplaceable service that save lives at times of emergency u Imbalanced policy decisions can impact their availability u Interference / reduced ability to access critical satellite services at times of disaster

should be unacceptable for any Member State

u Member States do not need to pick winners among technologies: all have a role to play u Spectrum decisions should allow for the development of both 5G & vital satellite

services

u NETPs & National Spectrum Planning should make clear provision for satellite services

knowing there is NO ALTERNATIVE

⇒ Member States should take informed decisions

Implementing the NETP Guidelines

Conclusions

What ITU Member States need to know (II)

u ITU plays a critical role in Disaster Relief and Spectrum Policy (WRCs) u ITU on Emergency Communications post WRC-15: “Recognizing that the immediate

availability of pre-identified and pre-coordinated frequencies, and/or spectrum are important for the successful use of radiocommunications in the very early stages of humanitarian assistance intervention for disaster relief will save many lives”

The ITU Role

Guidelines should help MSs assess if they have the required capabilities & frameworks in place to cope with disasters. For satellite this includes:

⇒ Have we got the required satellite equipment, does it work, are staff trained to use it? ⇒ Do regulatory barriers prevent satellite equipment entering the country or being used? ⇒ Is spectrum available to use the satellite service?
