How to See WiFi Networks on Google Earth
Acrylic WiFi Free works with GPS devices to georeference 802.11 networks as well as stations (STA’s) that have been identified during the scanning process to later visualize these WiFi networks on Google Earth.
In this blog entry, we will explain how to perform a wireless capture on 802.11 networks, including the localization of the detected devices and networks on a small project. The hardware used is the following:
• Integrated wireless card (Broadcom 43142) • GPS device (ND-100 GPS DONGLE)
The fist step is to access the GPS window (1), from where we can configure our GPS device (2). Once our GPS device parameters have been defined, click on the Start button to initiate satellite identification.
After satellite identification, the user will see the signal level for each one of the detected GPS satellites, as shown in the image below.
Once the GPS device has been configured and our site position has been identified, 802.11 network and station identification process can begin by starting a capture. To do that, select the desired interface (4) and then click on “Start” button. The use of a GPS device is required to visualize WiFi networks on Google Earth.
As the networks are identified, Acrylic WiFi shows the last detected network and station locations on the Networks window.
Once the capture is concluded, click on the “Stop” button to finish. Acrylic will prompt if you want to save the performed capture. Click on “Yes” and then select the folder where the pcap capture file will be saved.
Acrylic includes a simple tool the allows you to convert a pcap capture file into a KML file. To access this tool, go to “Tools” menu and select the option “pcap to KML”.
How to Load a KML File with WiFi Networks on Google Earth
The WiFi capture file conversion process will generate two KML files, one containing the identified networks, and the other one including the detected stations (STA’s).
Finally, we will be able to open the KML capture file that includes the access points identified during the capture process using Google Earth to visualize the locations where wireless networks have been detected, including information such as SSID, network type, security type, signal strength, and channel.
