What you'll learn
✓ Calculate and apply dB, dBm, dBi, EIRP, and link budgets for real Wi‑Fi deployment decisions.
✓ Decode 802.11 management, control, and data frames to diagnose connection and performance issues.
✓ Identify packet-level causes of retries, auth/assoc failures, and hidden throughput bottlenecks.
✓ Evaluate aggregation (A‑MSDU/A‑MPDU) and OFDMA behavior using meaningful QA test metrics.
✓ Understand Wi‑Fi 7 concepts (MLO, 6 GHz, 320 MHz) and their impact on test strategy.
✓ Build repeatable interoperability and environmental test plans that hold up in engineering review.
Requirements
● Basic networking knowledge (IP, Wi‑Fi basics, routers/APs, and client connectivity).
● Familiarity with technical troubleshooting concepts is helpful.
● No advanced RF math background required.
● No expensive lab equipment required; concepts are taught with practical real-world examples.
Description
This course is built for engineers who want to understand Wi-Fi the way it behaves in real deployments, not just how standards documents describe it.
You will start with RF foundations that are essential for practical decision-making: logarithmic thinking, dB/dBm/dBi, EIRP, path loss, and link budgets. From there, the course moves into 802.11 frame-level behavior so you can diagnose real connection failures, retry storms, and hidden reliability issues that speed tests often miss.
You will then analyze why throughput claims and real user experience often differ. We cover aggregation behavior, OFDMA expectations versus lab reality, and how to design tests that expose true system performance using meaningful metrics.
A dedicated section focuses on Wi-Fi 7, including Multi-Link Operation (MLO), 6 GHz, and 320 MHz planning tradeoffs. You'll learn which legacy QA assumptions break and how to upgrade existing Wi-Fi 6 test strategies without starting over.
The final part of the course addresses interoperability and environmental variables: client-router compatibility, temperature and humidity effects, and building repeatable, defensible test processes that hold up in engineering review.
No expensive lab setup is required to benefit from this course. The focus is practical reasoning, field-relevant diagnostics, and systematic QA thinking you can apply immediately in product validation, deployment planning, and troubleshooting.
Who this course is for
■ WLAN/Wi‑Fi engineers who want deeper protocol and RF-level understanding.
■ QA and validation engineers testing wireless devices, firmware, or access points.
■ Network engineers/admins who want to troubleshoot beyond surface-level speed tests.
■ Product and test teams preparing for Wi‑Fi 6/6E/7 real-world behavior and interoperability challenges.
