NTN Service Link

§1 — Definition
Supplemental Coverage from Space
A bounded context for considering how space-based network resources may complement terrestrial coverage without asserting service availability, geographic reach, entitlement, or performance.
§2 — Relationships
Closest related capability
Difference
Relationship
Closest comparison and adjacent concepts.
Supplemental Coverage from Space addresses a complementary coverage and regulatory context. It may use NTN architectures, but it is not synonymous with a payload type, feeder link, service link, or universal coverage model.
What separates them
Supplemental Coverage from Space is a United States regulatory framework for complementary coverage; NTN Service Link is the technical radio relationship between a platform and user equipment.
How they work together
An SCS implementation may involve an NTN service link, but the regulatory framework and the technical link are not synonymous.

§3 — Standards and AuthorityPrimary authority ↗ Primary authority ↗
Where the terminology comes from.
The FCC adopted the SCS framework in FCC 24-28 under GN Docket No. 23-65. 3GPP provides related NTN technical context, but the FCC order controls the cited United States regulatory meaning.
Single Network Future: Supplemental Coverage from Space
Federal Communications Commission · FCC 24-28; GN Docket No. 23-65
Adopts and explains the United States SCS framework, including its spectrum, licensing, interference, and public-safety context.

Non-Terrestrial Networks (NTN)
3rd Generation Partnership Project (3GPP) · Official 3GPP technology overview
Provides technical context for NTN access, platforms, links, payloads, and cellular integration adjacent to the FCC regulatory framework.
Technical NTN context does not replace the FCC's jurisdiction-specific SCS rules.
§4 — Evaluation
Apply the distinction to the decision at hand.
The category helps strategy and architecture teams identify coverage questions that require operator, technical, commercial, and regulatory evidence.
§5 — LJP Foundation
How this capability fits the package.
Supplemental Coverage from Space makes the coverage question visible while keeping it separate from payload processing and link definitions.
Supplemental Coverage from Space addresses the complementary coverage and regulatory question alongside—not in place of—the payload and link capabilities.
