ETSI MEC (Multi-access Edge Computing) is a global standard developed by the European Telecommunications Standards Institute (ETSI) to enable seamless and secure collaboration between different edge devices and networks, regardless of their manufacturer. MEC brings computing resources closer to where data is generated - at the edge of the network - improving speed, reducing latency, and enhancing security. By providing standardized frameworks and interfaces, ETSI MEC ensures that edge applications and services can work together efficiently, supporting innovations like smart cities, autonomous vehicles, and IoT deployments.
