Hands-on Practicals

Spectrum Analyser Setup, Use and In-Depth Analysis

This lab set gives students the necessary familiarity, experience and competence to analyse RF behaviour using spectrum analysers. Student explore spectrum analyser traces and charts and interpret the data to understand a transmitter’s impact on a Wi-Fi network. Exercises include:

Wi-Fi Protocol Analysis

The 10-lab Protocol Analyser lab set focusses on gaining familiarity with analysis tools, using protocol analysers to capture traffic and interpret frame traces:
1. Installation and familiarity with capabilities, configuration, and data visualisation
2. Creating, saving, viewing and modifying capture files
3. Device naming and prioritisation, traffic filtering, colouring rules and more
4. Performing live captures using defined collection criteria
5. Identifying significant network behaviours, metrics and statistics – to identify and isolate network problems
6. Using Protocol Analyser “Expert” features, including conversation analysis
7. Remote site packet trace capture using a remote AP

Understanding Frame Components

This 9-lab set focusses on using protocol analysis tools to capture and visualise multiple 802.11 frame types and formats. Familiarity with 802.11 frame structure and content is essential for effective Wi-Fi network troubleshooting.

Frame Exchanges

For effective Wi-Fi network troubleshooting it is essential to know how and when each 802.11 frame is used in interactive communication. Understanding Wi-Fi frame exchange rules and behaviour is critical to identifying expected and unexpected behaviour. This lab focusses on observing and explaining 802.11 WLAN behaviour using a protocol analyser.

Troubleshooting Wi-Fi Network Problems
This lab enables students to identify and diagnose a series of common Wi-Fi network problems.

Lifetime Post-Course Support

After completing this CWAP training course, delegates receive lifetime post-training support from LEVER Technology Group, to help them apply the technologies and skills they have learned with us, to provide career-long support, and to ensure they are better equipped for their future roles in IT and networking.
