• No economical backhaul for 4G/5G expansion or to deliver high-speed broadband to remote communities
• No quality access in remote areas for enterprise cloud applications
• No effective gate-to-gate solutions
• Limited quality of satellite access
• No global network
• No solution today for “home like” connectivity on waters
• High GEO latency prevents effective remote ops
• No global network
• Poor morale, welfare and recreation (MWR) experience due to throughput, quality gaps
• Limited resilience of GEO architecture
• Proprietary systems are expensive and take too long
Pain points
• Low latency for end-to-end encryption and cloud applications
• Plug-n-Play like terrestrial transport
• One global network for multi-national companies
• High focused capacity around airports
• Global coverage incl. polar routes
• Low latency for ‘office/home in the sky’
• High focused capacity in cruise hotspots
• Low latency for seamless ‘remote-to-shore’
• Reliable multi-satellite constellation
• Low latency for unmanned aero, advanced digitalization

ITU - The Strategic Goal of the Radiocommunication Sector (ITU-R)
“To Seek ways and means to ensure the rational, equitable, efficient and economical use of the radio-frequency spectrum and satellite-orbit resources and to promote flexibility for future expansion and new technological developments.”

Regulation that Supports Competition and Technology Developments
- Regulation should be designed to meet public interest and encourage competition- Raw material is availability of spectrum, especially for ubiquitous services- The development of new technologies that underlie non-GSO constellation designs is
complex and takes time- Unnecessary time constraints would force operators and manufacturers to select
simpler but less spectrally efficient technologies- Due to their strict application, ITU rules need to include sufficient time margin for non-
GSO deployments to account for uncontrollable delays, for example availability of launch vehicles

- Under Agenda Item 7, Issue A, WRC-19 will decide on deployment milestones for new non-GSO satellite systems and transition milestones for existing non-GSO satellite systems that are not yet fully deployed
- The aim is to balance prevention of spectrum speculation with sufficient regulatory certainty to foster innovation and the development of transformational systems
- CITEL Inter-American Proposal (IAP) provides the correct balance:Effective date: 1 Jan 2021

- The first milestone should be no earlier than 1 Jan 2024- Any early date does not consider the severe consequences of missing an ITU deadline, which could be
outside the control of an operator (e.g. manufacturing and/or launch delays)- Imposing strict milestones has the only effect of reducing the number of systems that will come to
fruition, affecting negatively the benefits that competition would bring to citizens, consumers and businesses
- Warehousing is a non-issue- Such a “safety net” is too short to warehouse spectrum
- There is no need for the first milestone to fall before WRC-23- In fact, should a system miss such strict first milestone, it would be too late for WRC-23 to remedy to
the regulatory damage suffered by the relevant administration- Resolves 3 of the CITEL IAP states existing systems shall provide information on their deployment
schedule no later than 1 Feb 2021; therefore, this information will be available at WRC-23- Administrations are urged to support the CITEL IAP
