5GNR (5G New Radio)

The radio access technology standard for 5G networks specified by 3GPP, supporting both Sub-6 GHz (e.g., 2.6 GHz) and millimeter-Wave (mmWave) frequency bands (e.g., 28, 39 GHz). NR enables flexible deployment from wide-area coverage to ultra-high-speed urban and indoor scenarios.

5GNR in context

The radio access network is where mobile devices attach to the operator's infrastructure. Attacks in this layer include IMSI catching, rogue base stations and downgrade attacks; defenses rest 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 they interlock, is essential for both design and audit work.

To place 5GNR in the wider telecom-security picture, review 6G, ADSL, DOCSIS, EAP, ETSI and Handoff (Handover) — each entry cross-references back to this page so you can walk the topic in either direction.
