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.

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 4G in the wider telecom-security picture, review 3G, 3GPP, 5GNR, 6G, ADSL and AES — each entry cross-references back to this page so you can walk the topic in either direction.
