§1 — Definition
NTN Feeder Link
The conceptual network-side radio relationship between a non-terrestrial platform and gateway-side infrastructure.
§2 — Relationships
Closest related capability
Difference
Relationship
Closest comparison and adjacent concepts.
NTN Feeder Link operates between gateway infrastructure and the platform. NTN Service Link operates between the platform and user equipment; payload capabilities describe what the platform does between those sides.
What separates them
The feeder link connects the platform to an NTN gateway; the service link connects the platform to user equipment.
How they work together
The two links describe opposite sides of the non-terrestrial access path and keep gateway dependencies separate from user-access questions.

§3 — Standards and AuthorityPrimary authority ↗ Primary authority ↗
Where the terminology comes from.
3GPP defines an NTN gateway as ground infrastructure connected to the payload through the feeder link and distinguishes that link from the service link.

§4 — Evaluation
Apply the distinction to the decision at hand.
The distinction helps architecture teams separate gateway dependencies, responsibilities, and evidence from device-facing access questions.
§5 — LJP Foundation
How this capability fits the package.
NTN Feeder Link keeps gateway-side infrastructure questions distinct from the user-facing Service Link and from payload-processing choices.
NTN Feeder Link addresses the gateway-facing relationship within the five-capability family.
