9 LPWAN Practice Quizzes and Videos
Quiz mastery targets are easiest to plan with threshold math:
\[ C_{\text{target}} = \left\lceil 0.8 \times N_{\text{questions}} \right\rceil \]
Worked example: For a 15-question quiz, target correct answers are \(\lceil 0.8 \times 15 \rceil = 12\). If a learner moves from 8/15 to 12/15, score rises from 53.3% to 80%, crossing mastery with four additional correct answers.
9.1 Introduction
This chapter provides comprehensive practice quizzes and video tutorials to sharpen your ability to apply LPWAN knowledge to deployment decisions. The quizzes require you to compare technologies, calculate duty cycle compliance, evaluate total cost of ownership, and diagnose design failures across real-world scenarios.
- Select the appropriate LPWAN technology (LoRaWAN, Sigfox, NB-IoT, LTE-M) by evaluating payload, message frequency, mobility, and coverage constraints
- Calculate duty cycle compliance under EU868 regulations and justify the correct message interval for a given spreading factor and payload size
- Compare 5-year and 10-year total cost of ownership across private and operator-managed LPWAN deployments
- Diagnose LPWAN deployment failures caused by duty cycle violations, payload limits, or operator dependency
- Assess trade-offs between infrastructure cost, recurring subscription fees, and operational reliability
- Distinguish between technology-selection criteria that are absolute constraints versus configurable parameters
These quizzes test your introduction-level knowledge of LPWAN technologies. They cover basic concepts like what LPWAN stands for, why it is useful for IoT, and how it differs from Wi-Fi or Bluetooth. Use them to confirm you have a solid foundation before diving into more advanced topics.
