Calculate the airtime and duty-cycle budget for a LoRa uplink at a given spreading factor and payload size.
Your checkpoint

Your checkpoint
A hand-drawn or text-based end-to-end architecture diagram for a smart-metering scenario labeling each communication link and the protocol used on it.
IoT Platform and Device Management
List the core capabilities of an IoT platform (device onboarding, device shadow, rule engine, OTA, data storage) and explain why each matters.
Explain device lifecycle states from registration through decommissioning and what triggers each transition.
Describe how a device shadow or twin keeps reported and desired state synchronized when a device is offline.
Outline the steps to onboard a device securely using per-device credentials and a bootstrap process.
Your checkpoint
A device lifecycle flowchart with at least six states and the events that cause each transition.
IoT Platform and Device Management & IoT Security
Compare MQTT, HTTP, and CoAP for device-to-platform telemetry in terms of overhead, reliability, and QoS.
Explain how the rule engine or stream processing routes telemetry to storage, alerts, and applications.
Identify the main attack surfaces in an IoT system: device, network, platform, and application layers.
Describe how mutual TLS, token-based authentication, and certificate rotation protect device-to-cloud channels.
Explain why default passwords and unpatched firmware are leading causes of IoT breaches and how to mitigate them.
Your checkpoint
A threat-model table listing at least eight threats mapped to the layer they affect, with one mitigation per threat.
IoT Security
Describe how a hardware root of trust and secure boot protect device integrity.
Explain the principle of least privilege as applied to device identities and platform roles.
Outline a firmware OTA update process that includes signing, verification, and rollback.
Distinguish data protection in transit from data protection at rest and give one control for each.
Your checkpoint
A secure OTA procedure checklist with at least eight steps from build signing to post-update verification.
IoT Overview and Architecture & IoT Applications and Industry Solutions
Describe the standard IoT reference architecture layers (perception, network, platform, application) and the function of each.
Explain how edge computing changes latency, bandwidth, and privacy trade-offs in IoT solutions.
Map at least four industry verticals (smart home, smart city, manufacturing, agriculture) to their key requirements and typical technologies.
Identify the main scalability and interoperability challenges in large IoT deployments.
Your checkpoint
A layered reference architecture diagram with one concrete example component and one protocol per layer.

Explain how network slicing and private networks support industrial IoT requirements.
Compare edge versus cloud processing for a latency-sensitive industrial control scenario.
Justify technology choices in a design against cost, power, coverage, and security constraints.
Your checkpoint
A two-page solution design for one industry scenario that names every technology choice and justifies it in one sentence each.
IoT Overview and Architecture & IoT Communication Technologies & IoT Networking and Connectivity & IoT Platform and Device Management & IoT Security & IoT Applications and Industry Solutions
