Practical training on the physical layer, data link layer, and security of wireless LAN using a spectrum analyzer, packet capture tool, Wireshark, etc. (compatible with Wireshark 4.X)
Perform spectrum analysis in the 2.4/5/6 GHz band using a spectrum analyzer to check external waves, DFS, interference, etc. and learn physical layer analysis methods.
Packet capture tool (CommView For WiFi) Acquire IEEE802.11 frames using Eye P.A. (Chanalyzer6) and Linux) and learn how to troubleshoot protocol operations, communication state transitions, and trend analysis techniques.
Actually use Wireshark4 and open source tools to capture and decrypt WPA2/WPA3, and learn security techniques, threats, and vulnerabilities.
*We strongly recommend that you take the introductory seminar on packet capture and trend analysis. |
