Post Processing Captures in Airtool with Python

For the past WLAN Professionals Conference in Phoenix, AZ (February 21-23, 2017), I collaborated with Brian Long for the development of a feature in Airtool to allow users to run a Python script for post processing capture files. The idea is pretty simple: after completing the capture, the user is presented with a dialog to choose a Python script for post processing the capture file.

Automatic data frame slicing in Airtool

Airtool Frame Slicing Preferences

Troubleshooting Wi-Fi networks at the protocol level involves the analysis of control, management, and data frames.
