HCIA-IoT case studies
HCIA-IoT · Put your knowledge to work in context.
HCIA-IoT is an associate-level certification for people starting a career in Internet of Things engineering, typically network engineers moving into IoT, field or solution engineers, and students who already understand basic IP networking. It tests breadth rather than deep specialisation: how IoT systems are layered, which wireless and wired technologies connect devices, how devices attach to a network and are managed from a platform, what security controls apply at device, network and platform level, and how these pieces come together in vertical solutions such as smart metering, manufacturing and smart cities. The HCIA-IoT case studies are 5 cases and about 3,503 words.
1Smart Campus: Edge or Cloud for 800 Cameras
Riverside University is deploying a smart-campus system across 40 buildings: 800 1080p cameras at 4 Mbps each, 2,000 environmental and energy sensors reporting every 60 seconds, 350 smart locks, and 120 Modbus energy meters. The only WAN link to the cloud is a 200 Mbps fiber.

A washing-machine plant runs 60 laser-guided AGVs along 4 m aisles between production lines. Each AGV sends 20 Hz telemetry and needs 10 Hz motion commands; the control loop tolerates 20 ms end-to-end latency and under 0.1% packet loss.
