OTA Firmware-Update Architecture for a 50,000-Device Smart-Meter Fleet
Overview
What this challenge is about.
Design a 4-stage OTA architecture for a smart-meter fleet, validate with failure injection, and earn a verifiable certificate.
The scenario
The Reykjavík smart-meter subsidiary (around USD 14M revenue, 52,000 NB-IoT meters across heating + electrical networks) faces regulatory pressure after the last bricking incident — the next botched update risks the utility's operating license.
The Brief
What you'll do, and what you'll demonstrate.
Design and validate an OTA architecture that prevents bricking via canary cohorts, signed images, and brick-resistant bootloader handoff across a 50,000-device fleet.
Earning criteria — what you'll demonstrate
- Design staged OTA architectures with telemetry-gated promotion
- Implement signed-image verification and dual-bank rollback safely
- Validate cyber-physical update systems with synthetic failure injection
- Author production runbooks that survive 3am rollout incidents
