NTN (Non-Terrestrial Networks)
A 3GPP standardized architecture for satellite and non-terrestrial network integration with terrestrial 5G networks. NTN supports LEO, MEO, and GEO satellites. Standardization is in progress.

NTN in context
Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how they interlock, is essential for both design and audit work.
To place NTN in the wider telecom-security picture, review LEO, ZSM, 3GPP, Attack Surface Mapping, Zigbee and 6G: each entry cross-references back to this page so you can walk the topic in either direction.
