Mobile edge computing (MEC) enables cloud computing capabilities and IT services at the edge of cellular networks. It addresses the long data paths and lack of determinism in quality of service (QoS) of traditional centralized architectures by relocating applications and services to the edge. This allows for campus area coverage, deterministic QoS, high availability, strong security and seamless mobility needed for demanding industrial Internet of Things (IoT) applications. The document discusses approaches like hybrid networks that separate control and user planes, as well as private LTE networks controlled by enterprises. It also highlights examples like Vodafone's 5G mobility lab demonstrating uses of MEC for areas like smart intersections and vehicle communications.
