5GNR (5G New Radio)
Categories: Radio Access NetworkProtocols and Standards
5GNR in context
The radio access network is the layer where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations, downgrade attacks and jamming, and defenses hinge on mutual authentication, integrity-protected signaling and Open RAN supply-chain hygiene.
Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how the specs interlock (for example 3GPP TS 33.501 with GSMA FS.34 for 5G SBA security), is essential for both design and audit work.
To place 5GNR in the wider telecom-security picture, review Handoff (Handover), 6G, ADSL, NB-IoT, OT and PoE.
