6G (Sixth Generation Mobile Network)

Next-generation mobile network technology currently under development, expected to launch in the 2030s. Research directions include terabit-per-second data rates, quantum-resistant encryption, integrated satellite communication, and AI-native architecture. Quantum-resistant cryptography and distributed security models are research focus areas; these are not guaranteed standards.

6G 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.

Security controls in telecom span signaling firewalls (SS7/Diameter/GTP screening at the network edge), transport encryption (IPsec, TLS, PRINS), identity and access on OSS/BSS, and monitoring at both the packet and log level. Controls are audited against GSMA FS.11/FS.19/FS.20/FS.36 and, in Europe, NIS2 sectoral rules.

To place 6G in the wider telecom-security picture, review EAP, Satellite Backhaul, IKEv2, 1G, 2G and 3G.
