5G/MEC Workloads
5G and Multi-access Edge Computing (MEC) workloads enable ultra-low-latency, high-bandwidth applications by placing compute resources close to end users and devices. Unlike hyperscale or enterprise workloads, 5G/MEC workloads are highly distributed, latency-critical, and tightly coupled with telecom infrastructure. They support AR/VR, robotics, autonomous vehicles, IoT backhaul, and private 5G networks for enterprises and campuses.
Overview
- Purpose: Provide compute and storage at the network edge to support latency-sensitive services.
- Scale: Thousands of MEC sites across metro regions, each with 10–200 kW capacity.
- Characteristics: Sub-20 ms response targets, distributed scaling, telecom-grade reliability.
- Comparison: Unlike CDN (throughput-heavy) or AI factories (compute-heavy), MEC focuses on deterministic latency and integration with 5G RAN/core.
Common Workloads
- AR/VR & XR: Rendering frames close to the user to avoid motion sickness.
- Autonomous Mobility: Vehicle-to-everything (V2X), robotaxi coordination, fleet telemetry.
- Industrial IoT: Factory-floor robotics, predictive maintenance, digital twins.
- Gaming: Cloud gaming nodes placed at metro edge to cut latency below 30 ms.
- Private 5G: Enterprises running dedicated MEC nodes on campuses or factories.

Facility Alignment
| Workload Mode | Best-Fit Facilities | Also Runs In | Notes |
|---|---|---|---|

Key Challenges
- Latency: Maintaining deterministic <20 ms across distributed edge sites.
- Scale: Orchestrating thousands of small sites vs. dozens of hyperscale campuses.
- CapEx/OpEx: Building and maintaining MEC nodes at scale is costly.
- Reliability: MEC nodes must meet telco-grade uptime (99.999%).
- Security: Thousands of edge sites increase attack surfaces; zero-trust is required.
- Integration: MEC workloads must interoperate with both telecom RAN/core and enterprise IT.

- Sustainability: Small nodes powered by renewable microgrids and ruggedized cooling.
FAQ
- How is MEC different from CDN? MEC is compute-focused (apps, inference, AR/VR); CDN is content-focused (caching, streaming).
- Where are MEC nodes deployed? At 5G tower sites, metro colocation centers, and enterprise campuses.
- Why is latency so strict? Apps like AR, robotics, and V2X break if RTT exceeds 20 ms.
- Do MEC nodes use GPUs? Yes, for inference, rendering, and AI acceleration in robotics/vision workloads.
- What’s the biggest bottleneck? Orchestrating thousands of distributed MEC sites while keeping costs manageable.
