IoT Applications and Industry Solutions
What the exam tests
IoT Applications and Industry Solutions tests whether you can map a vertical's requirements to architecture and technology choices: smart home, smart city, metering, industrial, agriculture and logistics.
Solution patterns
- Smart home: Wi-Fi for high-bandwidth devices, BLE for wearables and commissioning, ZigBee for low-power mesh lighting and sensors; cloud app for control; privacy and local fallback matter.
- Smart city: street lighting, parking and waste bins use NB-IoT controllers because they are numerous and spread over wide areas; a platform schedules and monitors.
- Smart metering: NB-IoT or PLC to concentrators; DLMS/COSEM data models; head-end system for billing.
- Industrial IoT: deterministic latency, TSN, 5G uRLLC, edge gateways and predictive maintenance; safety and OT/IT segmentation dominate.
- Agriculture: LoRa or NB-IoT soil and weather sensors, low duty cycle, long range, solar or battery power.
Worked example
A city wants to cut street-lighting energy by 30%. Each lamp gets an NB-IoT controller with a photocell and power meter. The platform groups lamps by zone, applies a dimming schedule and reports failures. Per-lamp control needs many low-cost endpoints over wide coverage, so NB-IoT fits; a Wi-Fi mesh would need dense backhaul and power; the platform, not the lamp, holds the schedule so it can be changed centrally.
Traps
Do not apply consumer Wi-Fi to city-scale outdoor deployments; do not ignore power budgets in agriculture; do not assume industrial IoT can share a best-effort network when closed-loop control is required.
