In this lab, we'll look at software applications that can use the WLAN Pi as an external Wi-Fi sensor for network scanning:
Kismet
Windows: WiFi Explorer Pro for the very first time!
macOS: WiFi Explorer Pro 3
WiFi Explorer Pro enables scanning of the 2.4 GHz, 5 GHz, and 6 GHz bands. The results from this lab will assist us in understanding the RF environment, which will be helpful when we get to the frame capture lab.
WiFi Explorer Pro initiates a SSH session to the WLAN Pi, continually switching its wireless interface to each Wi-Fi channel. Beacon frames are captured using a utility on the WLAN Pi, such as tcpdump, to build a list of Wi-Fi networks. The beacon data is processed on the scanning app to create a detailed channel audit of 802.11 networks that the WLAN Pi can hear.
The WLAN Pi can be geographically remote from the host running the Wi-Fi scanner. Remote network connectivity may be provided between the scanner application and the WLAN Pi sensor using some type of VPN access, such as Tailscale or ZeroTier.
