4G (Fourth Generation Mobile Network)
High-speed mobile network technology deployed globally from 2009 onward, primarily using LTE (Long Term Evolution) standards. 4G provides average speeds exceeding 100 Mbps (peak 1 Gbps+) and enabled smartphones, streaming video, and real-time applications like high-quality video conferencing.

4G in context
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 4G in the wider telecom-security picture, review 3G, 6G, 3GPP, 5G, HLS and IP.
