Availability Connectivity Barriers Affordability Awareness
Identifying the Gaps in Availability HIGH DENSITY MEDIUM DENSITY LOW DENSITY
Satellite Infrastructure HAPS FSO Terragraph ARIES
Solutions to Fit/Solve the Problem Close the Gap DENSE URBAN MEDIUM DENSITY LOW DENSITY Quality of connectivity Limited or no connectivity Limited or no connectivity HAPS SATELLITES Solar-powered, high altitude, long endurance station, free space optical Low-earth orbit and geosynchronous satellites, free space optical V BAND NETWORKS 60GHz high bandwidth wireless network
Network Capabilities Terrestrial Satellite Very good indoor and urban coverage High bit rate per user Only in densely populated areas Slow, phased and costly deployment Broad coverage Infrastructure resilience High Throughput Satellites offer superior performance Still relatively expensive for end-users No gradual deployment
HAPS & Other Networks: Synergies New broadband HAPS are designed to supplement Mobile and Satellite networks: HAPS will play and important role in enabling and accelerating mobile deployments HAPS will provide effective and affordable backhaul to connect areas where terrestrial backhaul technologies are uneconomical HAPS can complement and extend Satellite capabilities to further integrate with ground-based infrastructure in the domains of: Earth Observation Telecommunication Navigation
Technology advancements enabling HAPS today Li-ion batteries High efficiency solar panels Lightweight materials Autonomous aircraft avionics Key attributes of HAPS Aim - to provide backhaul solution globally to enable high-speed broadband delivery to underserved areas worldwide Footprint up to 100 km diameter Throughput >10 Gbps Altitude 20 km (well above commercial airspace) Circles in approximately 2-3 km radius to station keep Continuous station-keeping 3-12 months Service life approximately 10 years
Advantages of HAPS Wide-area coverage Footprints larger than 100 km in diameter Low cost Very limited ground infrastructure Low OPEX and CAPEX expenditure Rapid deployment and flexibility Short lead times Easy maintenance and payload reconfiguration
Advantages of HAPS Geographical reach Can reach remote sites on land or sea Continuity of service Advances in battery life Can operate continuously for more than 3 months Environmentally-friendly platforms Solar powered Almost no impact on the environment
Envisaged Applications Rural broadband Disaster relief services Multicasting/broadcasting Communications at temporary venues O erlay of terrestrial data li ks for resilie e or li k failure re o ery

HAPS Proponents: Synergies In 2017, Facebook and Airbus announced they will closely collaborate: To advance spectrum and aviation policy in support of HAPS deployment To continue demonstrate the viability of HAPS systems for providing broadband connectivity.
Spectrum Requirements
Spectrum to Achieve Global HAPS Frequency Application Direction BW Coverage 6GHz GW 80 MHz (x2) 5 Admins (R1, R3) 28/31GHz GW, CPE 300 MHz (x2) 47/48GHz GW, CPE 300 MHz (x2) 21.4-22 GHz GW CPE 600 MHz 24.25-27.5 GHz GW, CPE 3250 MHz 38-39.5 GHz GW, CPE 1500 MHz Existing HAPS bands 23 Admins (R1, R3) Global Candidate HAPS bands Existing bands alone are insufficient due to: Low Bandwidth = limited capacity Geographical restrictions = not global Technical restrictions = limited, costly coverage In some bands - Excessive rain attenuation = insufficient in remote areas and incompatible with HAPS design WRC-19 Agenda Item 1.14 invites to study additional HAPS identifications in the 38-39.5 GHz 21.4-22 GHz and 24.25-27.5 GHz frequency bands
Spectrum Considerations WP 5C developed a Preliminary New Draft Proposal (PDNR) indicating an approximate 4 GHz spectrum needs for broadband HAPS Forward Return GW => HAPS HAPS => CPE CPE => HAPS HAPS => GW 2 727 MHz 938 MHz 117 MHz 341 MHz At November 2017 WP 5C meeting: Contributions from several countries: o Australia, Canada, France, Germany, Korea, Mali, Mexico, Senegal, UAE, USA o Compilation of sharing study documents (totalling some 900 pages) Sharing Studies discussions and outcome o Total of 6 documents: 1 per band (6GHz, 21GHz, 26GHz, 28/31GHz, 38GHz, 47/48GHz) o Key issues discussed: separation distances, power control, shielding and the protection criteria for FSS, IMT and HAPS oa non-system specific (Power Flux Density) approach is being evaluated as an alternative method to demonstrate coexistence feasibility
Regional Views Support sharing and compatibility studies between HAPS and other services to ensure protection of services to which frequency bands are allocated without any constraint to these APT Supports consideration of this Agenda ite [ ] CEPT is of the ie that a y consideration of the frequency band 24.25-27.5 GHz under this Agenda item should not limit the possibility to identify the band for IMT on a global level under Agenda item 1.13 CEPT ASMG does t support a y additio al identifications to applications of HAPS irrespective of results of ongoing studies under AI 1.6 and AI 1.13 Support appropriate regulatory actions to facilitate the use of HAPS, including modifying regulatory provisions in currently identified bands and identifications in candidate bands ASMG ATU 7 Administrations (Bahamas, Brazil, Canada, Ecuador, Mexico, Uruguay, US) developed preliminary views in support of consideration of additional spectrum needs for HAPS Support e essary odifi atio s [ ] to facilitate HAPS development at global or regional level CITEL RCC
Key Takeaways Administrations are actively participating in HAPS discussions in ITU-R study groups and regional groups. Sharing studies suggest that coexistence between HAPS and existing services is feasible. Studies expected to be finalized at the next WP 5C meeting. WP 5C developed a PDNR indicating 4.1 GHz spectrum needs for Broadband HAPS Methods to resolve Agenda Item 1.14 should seek to facilitate access to broadband applications delivered by HAPS by addressing spectrum needs in candidate frequency bands
