Create a map of your neighborhood WiFi networks with your car and Raspberry

curiously, the most interesting "home" projects that have been known in recent times have Raspberry Pi starring. The minicomputer fashion has helped thousands of people get "mount" something with their own hands in what is known as a culture maker. One of the last projects we know are to create a complete map of WiFi networks a neighborhood using an car and a Raspberry Pi.

The term wardriving refers to "search for Wi-Fi wireless networks from a moving vehicle. It involves using a car or truck and a computer equipped with Wi-Fi, as a laptop or PDA, para detectar las redes” (Wikipedia). This is something really curious that serves to create a map of WiFi networks in a particular area.

And that is precisely what has been proposed Scott Helme, demonstrating that it is something simple and available to anyone wanting to investigate the matter. This equipped his car with a certain equipment and set to drive up and down the neighborhood. Total, 10442 WiFi access points were discovered. After gathering all this information, the user overturned the coordinates in Google Maps to create a map. On his personal website can be viewed results.

Specifically, 8174 the networks had discovered WPA protection, 85 thereof with WEP protection and 2183 without any protection. further, It realized the significant increase WiFi networks available compared to the study conducted similarly in the year 2013. It is clear that wireless technologies are increasingly important for users and society.

The necessary equipment

as we see, it is a combination of several devices available to anyone. Among them are an external battery 50.000 to feed the assembly mAh, a Raspberry Pi 3, Alfa WiFi module and a GPS module. All linked by gums.

Nevertheless, to get affordable range, placed the Raspberry Pi in the car window and WiFi and GPS antenna modules on the outside of the vehicle that is commonly used for radio reception. After, only he had to connect everything to your laptop and start saving data.

By the way, if ever you urge to do something similar, remember you can upload the data to Wigle, a collaborative map where anyone can dump the location of WiFi hotspots worldwide.
