Multi-access edge computing

Multi-access edge computing (MEC) is the architectural standard that places compute, storage, and networking resources directly within cellular base stations and radio access networks, collapsing the physical distance between mobile users and computational infrastructure. Standardized by ETSI, MEC is not merely a deployment of edge computing in telecom contexts; it formalizes the base station as a first-class compute node, creating a new tier in the computing hierarchy between the end device and the cloud.

The significance of MEC lies in its integration with 5G network slicing. A MEC host can be instantiated as part of a network slice, meaning that the same physical base station can host multiple isolated edge environments with distinct performance characteristics. A slice for augmented reality demands low-latency graphics rendering; a slice for industrial IoT demands deterministic response times. MEC makes the edge programmable in ways that previous generations of cellular infrastructure did not.

But MEC also introduces a structural tension. Telecommunications operators control the base stations, while application developers own the software. MEC requires these historically separate domains to share infrastructure, governance models, and revenue. The network function virtualization layer that enables MEC is a site of institutional contestation: who owns the compute resources in a base station, and who decides what workloads run there? The technical question of where to place computation cannot be separated from the political question of who controls the platform.
