Direct-to-Device (D2D) satellite providers face a complex regulatory landscape primarily defined by spectrum allocation, international treaties, and space sustainability mandates.
The primary regulatory risks identified in the sources include:
- Spectrum Misuse and Interference: The most significant risk involves the reuse of terrestrial mobile network operator (MNO) spectrum from space, which currently lacks formal recognition under international and domestic frameworks. Reusing these frequencies for satellite transmission is considered a “non-conforming use” and presents a high risk of causing harmful interference to existing terrestrial and space-based systems.
- International Treaty Compliance: International spectrum use is governed by the ITU Radio Regulations, a treaty to which the UK and USA are signatories. Current D2D operations using terrestrial spectrum often rely on No. 4.4 of these regulations, a provision intended for temporary or experimental use that offers no protection from interference and requires immediate shutdown if interference occurs.
- Slow Regulatory Evolution: The process for modifying national and international tables of frequency allocation is a multi-year endeavour. The ITU typically addresses these issues only during World Radiocommunication Conferences (WRC), which occur every four years, potentially delaying commercial rollouts for years.
- Geographic and Licensing Constraints: Regulators like the FCC have proposed limiting “Supplemental Coverage from Space” (SCS) to specific Geographically Independent Areas (GIAs) where a single entity holds all co-channel licences. This avoids interference at service area borders but limits the market for providers operating in regions with a patchwork of different carrier frequencies.
- Space Sustainability and Debris: Space sustainability policies and environmental concerns are expected to limit the size of satellite constellations, forcing operators to further optimise their deployments. Additionally, the large surface area of satellites used by providers like AST SpaceMobile poses an increased risk of space debris, which invites stricter regulatory oversight and mitigation requirements.
- National Security and Regional Bans: Providers must comply with radio exclusion zones—specific areas such as astronomy sites or national borders where transmissions are forbidden. Furthermore, satellite services are subject to diverse national laws, including regions where the possession of a satellite-capable device may be restricted or where specific features are legally prohibited.
To understand the regulatory challenge, consider the “Radio Border Patrol” analogy: currently, radio frequencies are like strictly fenced territories where terrestrial carriers and satellite operators are kept apart; D2D providers are attempting to remove these fences, requiring a massive, slow-moving legal effort to rewrite the rules of the land so that they can share the same space without causing a diplomatic incident (interference).
