Internet of Things (IoT) and Infrastructure introduces the technologies that connect physical objects to the internet and the business decisions behind using them.
It is a 3 competency unit course with no prerequisites, found in WGU's Cloud and Network Engineering degree and its AWS and Azure tracks.
Students often find the course broad. A single scenario can ask about sensors, data flows, cloud architecture, security and privacy at once, so the skill is connecting them into one coherent design.

What D337 Covers
WGU lists five competencies:
| Competency (summarized) | What it involves |
|---|---|
| Identify emerging IoT use cases | Examples in organizations, marketplaces and industries such as manufacturing, health and smart buildings |
| Determine business requirements for data collection and analysis | What to measure, how often, and what decisions the data supports |
| Identify IoT network and cloud architectures | Devices, gateways, edge processing, connectivity options and cloud platforms |
| Describe IoT security solutions | Device identity, encryption, patching, segmentation and monitoring |
| Define requirements for IoT ethics, access and privacy | Consent, data minimization, access control and responsible use |
Key Concepts Explained
A Layered IoT Architecture
A simple model has a device layer (sensors and actuators), a connectivity layer (Wi-Fi, cellular, low-power networks), an edge or gateway layer that filters data, and a cloud layer for storage, analytics and dashboards.
Example: A warehouse fits temperature sensors to cold-storage units. Sensors report every minute to a local gateway, which forwards only readings outside the safe range plus an hourly summary. The cloud platform stores the data and alerts staff by phone. Edge filtering cuts bandwidth and keeps alerts fast if the internet link is slow.
Why IoT Security Is Hard
Devices are numerous, often low-powered, and may run for years without updates. Default passwords, unencrypted traffic and devices on the same network as business systems create risk. Segmenting IoT devices and managing their identities are common responses.
Privacy by Design
Collect only what the use case needs, tell people what is collected, control who can see it and set retention limits. Wearables and smart-home devices raise these questions most sharply.
Typical Tasks and How to Approach Them
| Task type | What it tests | How to approach it |
|---|---|---|
| Use case analysis | Matching IoT to a business need | Start with the problem and the decision the data supports |
| Architecture description | Knowing the layers and options | Trace one reading from sensor to dashboard |
| Security recommendations | Applying controls to devices | Cover device, network, data and cloud layers |
| Ethics and privacy discussion | Responsible data use | Name affected people and the safeguards that protect them |
Comparing IoT Connectivity Options
Choosing how devices connect is a recurring decision in IoT scenarios. The right option depends on range, power, data volume and cost, so a comparison table is a useful revision tool.
| Option | Strengths | Typical fit |
|---|---|---|
| Wi-Fi | High bandwidth, widely available | Indoor devices with mains power |
| Bluetooth Low Energy | Very low power, short range | Wearables, nearby sensors |
| Zigbee or similar mesh | Low power, devices relay for each other | Smart buildings, home automation |
| Cellular (including low-power variants) | Wide coverage, mobile | Vehicles, remote equipment |
| LoRaWAN | Long range, very low power, small data | Agriculture, utility meters |
In a written answer, justify the choice against the requirement. "LoRaWAN because sensors are spread across farmland, send small readings and must run for years on batteries" shows reasoning an evaluator can follow.
Turning Sensor Data into Business Value
The data requirements competency is about purpose. Before choosing sensors, ask what decision the organization wants to make and what data would support it. Then decide how often readings are needed, how accurate they must be and how long they should be kept.
Example: A city wants to cut missed bin collections. Fill-level sensors reporting twice a day are enough to plan routes; reporting every second would add cost and data with no extra value. Readings older than a year can be summarized and deleted, which also supports privacy and storage limits.
Where Students Get Stuck
- Technology before purpose. Requirements come first; choose connectivity and platforms to fit them.
- Treating security as one line. Address each layer, not just "use encryption".
- Thin privacy sections. Ethics and privacy are a full competency, so give them real analysis.
Study Tips for D337
- Pick one industry example and use it to revise every competency.
- Draw a simple architecture diagram for each use case you study.
- Compare connectivity options by range, power use and bandwidth in a small table.
- Link back to Ethics in Technology for privacy reasoning.

Frequently Asked Questions
No. WGU's program guides list no prerequisites for Internet of Things (IoT) and Infrastructure.
It is part of the B.S. Cloud and Network Engineering, including the AWS and Azure tracks.
The competencies focus on use cases, requirements, architectures, security and privacy rather than building devices.
Processing data close to the devices, for example on a gateway, so less data travels to the cloud and responses are faster.
Enough to meet the rubric. It is a full competency, so a short line is rarely sufficient.
No. We provide explanations, custom outlines and feedback so you can complete it yourself.
